10 Excellent Reverse Osmosis Systems For Home – Ideas For You

You may ask why purify ‘safe’ water?iSpring RCC7 WQA Gold Seal Certified 5-Stage Reverse Osmosis Drinking Water Filter System

Is our water really safe? EPA gives its best efforts to ensure that every household receives safe and healthy water from the supplier. But, unfortunately, some contaminants do not fall under EPA’s scope. We, therefore, need to purify it further.

Reverse Osmosis (RO) is the process that gives water the healthy, pure and sweet quality for the food processing, drinking and the even for the aquarium if any. Water is fed to the purifying RO system installed under the sink, and a pump takes it to a storage tank from where it is tapped through a faucet. A labeled RO diagram would help cut on the installation cost as the home owner can install the system without an expert’s help.

Want to know more?

From the first commercial use of a reverse osmosis in 1977, RO systems have been refined and re-defined to give homeowners healthy water at an affordable price. Today, RO systems are cheap and small enough to be bought and used by each household. There are many models in the market today and choosing the best among them may prove to be a daunting task.

Buying a Reverse Osmosis filtration system is like buying a car in the sense that you buy a car with the goal of using it for years. A reverse osmosis filtration system should be looked at in that light, so you have to be extremely sure which system will best serve your immediate and long term needs.

The answer to that question can only be found after conducting a thorough research and testing out the different types of reverse osmosis systems. Unfortunately, you may not have the time or resources needed to carry out that task and so we took it upon ourselves to do the research and testing and provide you with the best reverse osmosis system for your home.

Now, let’s get started.

This system was recommended to me by a friend and after installing it and having it running for about three months I couldn't be happier with it. The water is hands down the best I've ever tasted from any source and it's completely eliminated the need to buy bottled water for my wife and I so it will pay for itself in about a year. I also bought a TDS meter to measure the total dissolved solids in our water (HM Digital TDS-4). Our tap water consistently measures 690-720 ppm which is extremely high and consequently, it tastes pretty terrible. Our previous faucet mounted Pur filter only made a marginal improvement. The water coming out of the RO system now measures at around 25 ppm and tastes amazing.From reading most of the reviews here and from my personal experience of installing it, I put together some information that I've given to friends and thought it would be helpful to have it consolidated into one post here. A few reviews mentioned that the main shut-off valve that comes with the RO system started leaking after a while and that you'll be much better off if you just replace it with a better one from the start. The valve is $11 and you can get it at Home Depot and I opted to replace it from the start.It's a Watts 1/4 in. Plastic Adapter Stop Valve model #:P-467CS and Home Depot SKU: 1000018247Just a few notes regarding the installation:Very important: Cut all hoses so the ends are square and and the cuts are clean before making the connections or they may leak. I did that and I've had no leaks, but I can see how you might have leaks if you decide to skip this very important step which is also mentioned in the installation instructions.A few reviews mentioned that changing the order of the filters so the mineral stage comes before storage tank improves the taste of the water. I opted to do this and have never looked back as the water tastes amazingly good.The way it's configured out of the box (after the 3 big filters) is RO Membrane->Storage Tank->Carbon->Mineral->FaucetChange it to RO Membrane->Mineral->Storage Tank->Carbon->Faucet.When you're ready to run water through it for the first time (and whenever you change filters), disconnect the input hose to the RO membrane and flush the first three stages into a bucket. Just like a faucet-mounted filter (ie: Pur, Brita), the water will come out gray at first from the residual carbon so it's probably better not to send all that into the RO membrane. Once the water runs clear connect it to the RO membrane.I think the rest of this is in the instruction manual, but I'll mention it anyway:After you re-connect the RO membrane, keep the valve to the storage tank off and let the water run for a while. It will only trickle out and like the carbon filters, the RO membrane needs to be flushed for a little while and you don't want that going into the storage tank.When you're ready to fill the storage tank, it takes about two hours to fill. Once the tank is full, open the faucet and let it drain it completely and re-fill. You'll want to do that twice before using it. The water will have some bubbles in it at the beginning and it will gradually become very clear.I think that covers it! All of that made a for a leak-free installation and some very tasty water!Since we don't need to buy bottled water anymore, we bought a few of these reusable bottles on Amazon:Copco 2510-2183 Chevron Hydra Bottle, 16.9-Ounce, Neon Orange Dots

My old RO filter (with UV) was not working right, even after replacing all the filters. So I was looking for a new RO system with good reviews and decided on 2 systems: Tap Master TMAFC Artesian Full Contact Reverse Osmosis with Alkaline by Perfect Water and iSpring 6-stage with RO Alkaline. The Tap Master had tons of great feedback, but so was iSpring (the non-alkaline model). The only reason why I ended up purchasing iSpring was the price.DAY 1The system came in a well packaged box and I found everything easily including some spare parts for future use, which I appreciate. Fittings and pipes were included. All I need was the tools (wrench, scissors, etc) and a Teflon sealer that I got from Home Depot. I noticed a little trace of water and I found out that iSpring did a real test for quality control so that's a good thing.Installation was not hard, but it took me 45-60 minutes because I had to make sure that all fittings were tight and I also labeled the in/out just for future references, steps that most people won't do or not required to get the system up and running. The manual is clear and upon my purchase, the seller emailed me a youtube link that shows how to install it.Once everything was installed, I ran the water for about 10-20 minutes just to flush the system. I used HM Digital TDS-EZ TDS Water Quality Tester and got 150+ PPM (parts per million) in the beginning, and got better as I continually ran the water within minutes to as low as 20 PPM. I also tested a very popular bottled water that I like, and it showed the same 20 PPM with similar taste, which is great. After about an hour or two, it seems to stay within the 15-45 PPM range.Note on PPM:0-50 PPM = ideal water50-100 PPM = carbon filtered water100-200 PPM = hard water200-300 PPM = average tap water300-400 PPM = high total dissolved solid (TDS)500 PPM = US EPA's high contaminant levelI've run it off and on for a few hours now and saw no leak. Everything works great. The water quality is crisp and better yet, the Alkaline level is better than just an ordinary RO (alkaline has many benefits and will help you detoxify your body naturally).DAY 2Tested the water often and I get 20-40 PPM. Water came out with less bubbles.DAY 3As of now, the PPM is constantly in the low 20s with very little bubbles. This system runs very quietly and I've never heard any noise from it. I will update this review if I see some degradation in quality other than normal wear/tear or scheduled filter change (which is recommended every 6 months for some, 1 year for the other). Overall, I am happy with the quality and most importantly, I have a good, clean and great tasting water again. I will not have any problem recommending this system to anyone.

iSpring 6 Stage Reverse Osmosis SystemThe water in my area of North Chicagoland was not too bad but I want to remove all chlorine and fluoride as well as all the particles. I recently bought a house and have a 2yr old daughter. So this was an investment in health on many levels. Thus the reason to go with the 6 stage alkaline setup. We had been using PUR faucet filters and I was tired of paying $15 every six weeks for what I am sure is not nearly as clean as an RO system.So I read the reviews here and checked out their website. I also decided to get their whole house system as well. This way we can clean up all the water for the two bathrooms as well as the dishwasher, clothes washer and the showers.It shipped very quickly and it was double boxed. The construction quality of the system was good. The RO System took just over an hour to install. I already had a hole in the sink counter so the faucet install was very quick. I found the color coded hoses to be very helpful. I got it installed without having to watch the videos and after one quick fix for the last several months have had zero leaks.One tip during installation is to make sure the lines are cut with clean, flat facing ends. If its a bit off angle then it could develop a leak. All the parts fit my existing pipes without having to buy anything extra.After running the system for a while I did a PPM test and it came out at 10-15. That was impressive. Prior to the filters being installed it was at 150 PPM. The taste is very clear as is the clarity. I ran a quick water test and the chlorine came out at zero and the PH came out at around 6.5. This is a great number. Ideally, the pH of your water should be somewhere between 6 and 8. I am very happy with the filter and would definitely recommend it.

Let’s now explore some of its great features here;

Features:

  • Solid brass made faucet with nickel finish for sublime feel and appearance. This European-style round-top faucet features a durable ceramic valve and a quarter turn handle. It looks elegant and fits seamlessly in the kitchen sink to compliment the kitchen design.
  • The iSpring features calcium carbonate water filters together with red mineral stones. The calcium carbonate works by getting rid of minerals from water that changes its odor and taste. The red mineral stone features ionized minerals that later add rich minerals to the mineral free water to make it more wholesome.
  • This 6-stage RO comes equipped with transparent 1st stage housing for two main purposes. The first purpose is to let the user see the iSpring’s filtration process as the contaminants are flushed out. As for the second purpose, the user gets to inspect the filters to determine whether they need replacing.
  • This under-the-sink filtration system features quick fitting connections that are color coded to help simplify the installation process. All DIY homeowners will relish the challenge of installing this heavy-duty filtration system as it is made simple by the installation videos that are readily available online.
  • The iSpring features a GAC filter as well as a CTO filter to provide additional protection for the sensitive RO membrane. The GAC filter has loose carbon that works extremely well at flushing out large contaminants from the water. Smaller contaminants and mineral deposits in the water are then filtered out by the highly effective CTO carbon block filter. Getting rid of these impurities enhances the lifespan and performance of the RO membrane.
  • Advanced filtration system that flushes out over 1,000 water contaminants
  • The RCC7AK features a thin-film composite semi-permeable RO membrane. This semi-permeable membrane provides a mindboggling filtration competence of up to 0.0001 microns. To put that into perspective, a single human hair measures about 50 microns.
  • The calcite rich alkaline filters of the iSpring not only remineralize the water, but also balances the pH of the water to make it more ideal for human consumption.

Conclusion

Here is the bottom line:

So why is iSpring number one on our list? Well, it is quite simple. For a 6 stage filtration system, the iSpring is pocket-friendly unlike other 6 stage models. You are sure to get your money’s worth with this unit. What’s more, iSpring RCC7AK is extremely durable and has a lot going for it in terms of features.

All things considered, the iSpring is not a basic RO system by any chance. It is a solid, advanced RO water filter system and that I would strongly recommend as a must buy model if it meets your needs.

PROS:
  • Pocket-friendly price
  • Filters over 1,000 contaminants in the water
  • Compact design that fits under the sink cabinet with ease
  • Easy installation
  • Cost effective water usage

CONS:
  • None

This is a best quality system. I order 2 system from them in one moth. One of them has problem with the tank, the support team call me 2 hours after I was send the email, and the replace tank came three days after. Excellent tech support, and good price. Extra filters will save for another year. Fast delivery, Very easy installation. The system came with white housing and I request them to change all for clear housing. They change it with no extra charge. I can see all the filters though the clear housings. The water came into the first housing. When I see the filter dirty, I change this filter more frequently to keep other filers last longer. Thanks

I recently Purchased the 5 Stage Home Drinking Reverse Osmosis System PLUS Extra Full Set- 4 Water Filter from Express Water.I purchased this unit for our home, it was installed under the kitchen sink. Due to my hobby (obsession) of salt water reef tanks, throughout the years I have purchased and used numerous reverse osmosis deionization units from many various companies. The unit I currently use for my reef tank doesn’t require a storage tank but came with a dual TDS (total dissolved solids) meter and deionization stage to remove the last of the TDS. That unit cost twice as much as the unit from Express Water, HOWEVER it falls short of the quality unit I just installed from Express Water. This 5 stage unit is far more superior to the one I paid twice as much for.For example, this product takes into consideration the task of replacing the filters, they equipped their units with swivel connection to allow for the membrane canister to be open without having to remove the ¼” tubing (which illuminates the possibility to form leaks after a few times of disconnecting and reconnecting the line)They also perform a pressure test of the membrane canister to ensure no leaks prior to shipment (no other unit that I purchased in the past did that)The instruction booklet was very clear and even offered color pictures, diagrams and schematics to aid in easy installation. And to go one step further, each connection that needed to be made to the inlet water, waste water, storage tank, and faucet were labeled on the unit itself. This company clearly understands the complexity of tackling a task like this and has taken every step to eliminate frustration, making it easy for just about any skill level to tackle this job.After installation I followed the instructions and allowed the tank to fill up and then drain it completely, the water was blackish/grey (which is normal due to the final carbon filter being flushed out) then after filling it again I tested the TDS, 7ppm which tells me the unit is doing its job but I knew it could do better than that, in which I then emptied the tank for a second time and let it fill back up. The TDS meter reading the second time was 2ppm…. MUCH BETTER.You can’t have the good without the bad: the provided ½” slip joint adapter for the feed water wouldn’t work for the shut off valve I had under the sink, my valve has a 3/8” outlet. Luckily I had the right 3/8” adapter handy in my miscellaneous parts from all the other units I’ve had over the years and installed it instead. I’m not sure how feasible it would be to add that adapter to the list but it will save some frustration. I looked on line and currently this part can be purchased for $13 (JG Speedfit ASVPP1LF 3/8-Inch by 3/8-Inch by 1/4-Inch Angle Stop Adapter Valve). Please be sure to take that into consideration when purchasing this unit.And Lastly, The wrench that was provided is to aid opening the large canisters during filter replacement. However the membrane housing is slightly smaller and the wrench provided will not aid in opening it. This housing was really hard to open and takes some muscle power to get it open. There is a filter wrench to open housing however it wasn’t provided. I can’t provide a name or part number for that though because there’s many options to choose from. However for me, I was lucky enough to have one handy to get it open.If those 2 concerns were addressed and rectified I would give this purchase and experience 5 gold stars. All in all, the best unit money can buy. I would recommend this unit to anyone that is in the market for a whole home RO unit.
March 6, 2015
I'm rating this 5 stars because the unit is as good as you could get for the money. Granted, for more money you could have more expensive fittings, etc, but they are really not necessary unless you are going to be constantly moving and reassembling.This is my 3rd unit for the house one in downstairs kitchen and one upstairs as well, replacing a 12-year old system that's never caused a problem other than a leak in the UV two weeks ago. Sure I could have replaced just the UV but hey it's time for a complete new system.Complaints about the clarity of the instructions are unfounded as far as I'm concerned. I was replacing a similar unit (different brand) but there were no parts of the old system re-used other than the metal fitting on the cold water pipe, which still required the new compression fitting. The only difficulty with the instructions was the slightly upgraded output faucet which was not covered, but easy to figure out the difference and install.The main caution, as said by a few others, is to make sure you seat the tubes fully into the fittings... it's covered well in the manual and on youtube, but I still managed to have one leak afterward, which was hectic since I already had the unit on the wall of the cabinet and it was now full of water and pretty heavy. Push those tubes into the fitting HARD so you can feel when it goes that last 3/8 of an inch.PROs vs the older unit:1. Very very nice that they pre-assembled the filter portion, that saves probably 45 minutes for you.2. Tubing diagram, in color, makes assembly and troubleshooting very easy.3. This unit has about twice the water volume coming out of the faucet, which is nice if you're filling a coffee pot.4. Extra Filters includedCONs vs older unit:1. Does not include the UV sanitizer, and they point out twice in the instructions that you need that if you have any chance of microbial pollution. If you are using city water, it's probably not needed, but those of us in the country will need them.2. Not one complaint about the purchased unit itself. Good quality.I'm almost 75 years old and assembled this without help. I'm blind in one eye, a little senile, and have problems crouching for any period of time and even worse trying to get back up from under the sink. I'm sure it took me twice as long as most people, but the result was well worth it. I like the color coded tubing, easy to see where things go and come from under the sink.Suggestions for easier assembly:1. Install the faucet first, with the tubing left full length2. Install the input line from the cold water pipe, leaving the tubing full length3. Install the tank, tubing full length4. Install the drain tube cut to the length since the junction with the sink drainpipe is near the front.5. Place a large rectangular plastic dish pan in front of the cabinet and assemble the connections there, so that you can turn it on and check for leaks before hanging the unit on the cabinet wall. That way you can easily see and fix any leaks without making a puddle under the sink.

Let us now look at some of its many features:

Features:

  • The Express Water features an airtight frame that keeps out air and thus contaminations that may be carried by air. All Express Water units are tested for air leaks using air injection pressure testers before shipping to ensure they meet the highest standards of the brand.
  • This five stage filtration system is fitted with a pressure tight frame to guarantee its users maximum durability when subjected to normal working pressure. The pressure tight quality (just like the air tight quality) of the Express Water helps maintain the freshness of the filtered water.
  • Comes with a polypropylene sediment filter as the first line of defence against contaminated water. This polypropylene filter excels at filtering out all large contamination such as dirt, rust, silt, etc. from water.
  • Both the Granular Activated Carbon (GAC) filter and the CTO carbon filter on the Express Water are made entirely from coconut shell extracts. Not only do these filters flush out residual dirt and chemical compounds found in water but they also restore the natural odor and taste of water.
  • The semi-permeable RO membrane in this filtration system is built specially to filter out 99 percent of contaminants in water including health-hazard contaminants such as bacteria and viruses.
  • The Express Water comes equipped with an inline polishing filter as the last stage of the filtration process. The work of this inline filter is to get rid of all bad odour and tastes and finally stabilize the taste of water by adding health friendly minerals to the water.
  • Compact design that fits in all standard sized under counter kitchen cabinets. The compact design of this five-stage filtration system also makes installation and maintenance easy.
  • This filtration unit features color coordinated caps and connectors that indicate where hoses are to be inserted. Also, all the filter housings are labeled with the corresponding filter number to simplify the replacement process for all non-professionals and DIYs.
  • The Express Water features an adjustable pressure mechanism that puts out clean, filtered water at an astounding rate of 0.8 gallons per minute.

Conclusion

To sum it all up:

With over a whopping 27 years in the business of producing water filtration systems, it is fair to say that the Express Water brand is full of expertise in the water filtration industry. This experience translates directly into the quality of their products as evidenced by this model.

This filtration system is one of the best 5 stage RO models out there. So when you buy the Express Water, you are not only getting four complementary filters and purified water , but you are buying into the entire history of the brand.

PROS:
  • Premium quality
  • Easy installation
  • Excellent performance
  • Super-fast flow rate of water
  • Comes with four replacement filters

CONS:
  • None

iSpring RCC7 WQA Gold Seal Certified 5-Stage Reverse Osmosis Drinking Water Filter System

iSpring RCC7 WQA Gold Seal Certified 5-Stage Reverse Osmosis Drinking Water Filter System

iSpring RCC7WQA is very similar to its bigger brother, the iSpring RCC7AK in almost every aspect. Both of these RO models are from the same company and as such feature the same design cues and features. They both look alike, in terms of shape and size that you couldn’t set them apart in a line-up.

Perhaps the most notable difference is iSpring RCC7WQA is 5 stage RO system compared to the 6 stage iSpring RCC7AK. Another notable difference is the discounted price of the iSpring RCCWQA. But just like the first one, the second difference aforementioned cannot be spotted by looking at the two units side by side.

This will be my third RO system to install. The first was 15 years ago and I replaced it 10 years later. The third one I installed due to moving to another house. I almost decided not to go with a RO system, not because they are not effective but because of their bulkiness and tendency to waste water. But, I couldn't stand the thoughts of spending nearly 75% more for something that doesn't remove all the contaminants a RO system is capable of doing. I Looked at a few RO systems and finally narrowed it down to the iSpring. I liked the fact that it includes the brushed nickle faucet, were another vendor wanted an extra $45 for the same. The faucet that comes with the iSpring is very well made.and looks great. The system is easy to install with a few hours time. Instructions are well written, although there were a couple of things I had to search for. They apparently have the same instruction manual for UV systems as for non UV systems which may cause some to get confused on where one of the hoses connects. It's in the manual though. Just have to backtrack and look at pictures. I turned on the system and had two leaks which were my fault. I didn't have a couple of hoses pushed in tight enough. After doing it right, I've had zero leaks. This system is very well made with good, quality products and workmanship. They even throw in a few extra items, like valves and O-rings, not to mention the water detection alarm. Honestly, I'm not sure how they can sell the system for this price, especially with the expensive looking faucet. System runs quiet, too. I've known some RO systems that were noisey. I needed a washer plate to go under my faucet since the existing hole (for a soap dispenser) was a tad too large. I had superb customer service from the company and they shipped the washer to me free of charge.

This RO filter is really nice. I was able to install it myself while my family watched the super bowl. It wasn't exactly easy, but I managed to get it all set up with no drips, no leaks, no booboos, etc.; not even much swearing.This morning we used a TDS tester to compare tap to filtered. Tap, which tastes oddly like the smell of a pool noodle, tested at 42 TDS. The RO filtered water has no residual flavor and tested at 9 TDS. Our previous house had tap water in the 300-400 range of TDS, so even though we were dropping by 90%, we still wanted the extra cleaning and purifying effect of the RO system.So far, quite happy.
February 7, 2015
My Las Vegas tap water reads 506 parts per million of total dissolved solids. A day after this filter was installed, it's down to 25!Took me a couple hours to install as I was doing other work under the sink. Instructions are mostly clear, but do watch the recommended YouTube video, as it clarified a few things, especially the connection to the faucet.PUSH THE QUICK-CONNECT TUBING IN FARTHER THAN YOU THINK! It seats itself a bit on insertion, then you have to push it firmly farther to connect it securely! Or you'll end up confused with water sprinkling out of your connections.Setup is a bit daunting with all the parts before you begin, but it's pretty easy. They also include extra parts, which helped when I accidentally cracked a joint.

Features:

  • The iSpring RCC7WQA comes with a 3.2-gallon tank for storing filtered water for instant access. The tank reservoir is both air tight and pressure tight to keep out contamination and preserve the freshness of the filtered water.
  • This 5 stage filtration system features an adjustable pressure control that can easily put out 75 gallons of water per day. This enhanced pressure ensures water is readily available at all times. The iSpring’s water pressure combined with its 3.2-gallon tank make it suitable for use by a large family or even for commercial needs such as a small restaurant.
  • Solid brass-made faucet with nickel finish for sublime feel and appearance. This European-style round-top faucet features a durable ceramic valve and a quarter turn handle.
  • The RCC7WQA features a thorough pre-filter process that comprises of the first three filtration stages. The pre-filter stage essentially begins once the unfiltered water enters the filtration system. In this three-part stage, large contaminants such as dirt and chemical compounds are flushed out of the water to protect the RO membrane from damage.
  • Like the RCC7AK model, the iSpring RCC7WQA features a transparent filter housing that not only shows the filtration process taking place but allows the user to monitor the condition of the filters for replacement purposes.
  • This five stage RO system is compact. The whole system measures about 17.5 inches by 14.5 inches by 5.5 inches meaning it can fit in all standard sized kitchen cabinets.
  • Features output lines for filtered water that can be connected to various equipment units such as an aquarium, a refrigerator, and a coffeemaker, etc.
  • The iSpring features a GAC filter as well as a CTO filter to provide additional protection for the sensitive RO membrane. The GAC filter has loose carbon that works extremely well at flushing out large contaminants from the water. Smaller contaminants and mineral deposits in the water are then filtered out by the highly effective CTO carbon block filter.

Conclusion

What are our final thoughts?

Some people may be put off with the uncanny similarities between the two models from iSpring but when you stop and think about it for a minute, you realize that the similarity is a good thing. The iSpring manufacturers got it spot on with the RCC7WQA model because it employs the same characteristics as the RCC7AK model of which are nothing short of a master class.

So, if you own a small restaurant or a big house, regardless the family size, the iSpring RCC7WQA represents an attractive prospect for a filtration system and therefore you should consider buying it.

PROS:
  • Easy installation and maintenance
  • Filters out over 1,000 different water contaminants
  • Excellent performance
  • Great tasting water
  • Enhances water efficiency

CONS:
  • None

I purchased from Costco. As of Jan 2011, Costco is currently selling it for $189 with $30 MFG rebate, so the unit can be purchased at $159 with tax.I replaced an older GE GXRM10GBL Reverse Osmosis Water Filtration System purchased at Home Depot with this Watts unit. Where this system wins out is the ease of maintenance. It's very easy to pop any of the filter cartridges in and out. GE system was harder to maintain and some of the parts broke during maintenance. The main issue was that whenever I need to sanitize the system or replace RO cartridge, I had to open the plastic cap to the RO cartridge holder, which is made out of fairly light plastic. Every 1-2 years, after opening a couple of times, the plastic cab would break when I screw it back on. The replacement part for the RO cartridge holder is $150, which is the same price as buying a new unit.Here is my comparison, as of Jan 2011. Watts is a clear winner in my mind. Just a lot less hassle to maintain and probably cheaper in the long run. I'll probably update the post after a year or so to see if Watts still holds up well.---------------------------------------------Initial Price - Slight advantage GE. GE is $150 from HomeDepot where $189 with $30 MFG Rebate from CostcoOS Membrane Cost - Slight advantage GE. We replace this every 2-3 years. It's $50 for GE replacement cartridge from homedepot.com (FX12M) and $61 for Watts from filterfast.comCarbon filter Cost - Advantage Watts. Watt's it's only $50 for 1 year replacement set that replace pre-filters every 6 months and post filter every 12 months. For GE it's $75 a year ($37 for a pre/post cartridge pair (FX12P) from filterfast 2 pair a year). which replace post pre/post every 6 months. In my opinion, post filter only need replacing every 12 monthsNoise - Advantage Watts. Both make sound when ro process take place, but Watts is quieter. With GE, I can really hear it in the middle of night.Water quality - Same. My family can't taste the difference. Both specs seem to remove about same amount of all the contaminants.Initial Install - Slight advantage Watts. The system is more well designed and it's a bit easier to install although the GE one was not badReplacing pre/post filter - Advantage Watts. Watts takes me 10 seconds. GE takes me 10 minutes and water can get spilled easily.Replacing RO membrane - Advantage Watts. Watts takes me 5 seconds, GE takes me 20 minutes if everything goes well. I also have to have 2 very large clamps to open up the RO cartridge holder.Sanitize system - Advantage Watts. Watt is a lot easier to sanitize, takes 5 minutes to put in the bleach, and 4 hours flush afterwards, which can be unattended. GE require us to remove pre/post/RO membrane, and sanitize, and then put everything back. It's something that takes me about an hour, with 4 hours flush time in between. And water gets spilled easily.Durability - Advantage Watts. I haven't had Watts for long, but I can tell by how simple it is to swap the cartridges that it won't break easily. We simply don't have to take anything apart during maintenance where as GE requires you to do more mechanical things. Parts of GE breaks system after a couple sanitization or replacing RO membrane. Buy parts is a big pain since local stores don't sell it and have to call GE to older. Some parts are very expensive.Jan 13, 2012Updating after an year.....---------------------------------------------Durability comment about WATTS above holds so far, nothing breaking. Water still tastes great.The indicator light on the faucet, indicating filter need to change, seem to light up earlier than what the document replacement time should be ... So I end up ignoring that light.PS. if you are installing an RO system yourself (any RO system), make sure plumbing is done right and always check for slow leaks every month. With RO systems, the water pressure in some pipes build up slowly as filtered water gets created. So don't just install the system and assume there are no leaks. Check in 1 day, a week, then in a month...
February 2, 2011
Since moving into my house, I relied upon a custom installed Culligan 3 stage reverse osmosis filtration system (under the sink). Every year I paid a service rep to come to the house and replace filters and service the system. Costs ranged anywhere from $125 TO $175 including parts. (As a side note, in the 8 years Culligan serviced my system, they never cleaned the tank.) This year I called for service and was told the cost would be over $250 in parts and labor to replace the 3 filters and membrane. I had enough at this point and looked for a cost effective (and updated) alternative solution. Culligan also offered to lease me a system for over $300 a year that included servicing. I said no.After much research, I decided on this Watts Premier. I will not bother detailing specification comparisons because those are readily available on the Internet and all these systems essentially provide same filter performance. Since my plumbing was already setup for this system by Culligan, I figured no big deal in switching out. More on that later. Anyway, the product arrived and I was not dissapointed. The product was packed very well with no missing items. The system is comprised of quality components all around. The tank was actually better made and larger than my Culligan tank (8 years old). The filter components are made of quality material and far easier to replace than those on my Culligan system. The supplied quick connectors worked great. Everything is color coded and instructions are OK, though a little more detail would be warranted. The faucet provided is actually better quality than my Culligan faucet and has a filter replacement indicator light. Note that the faucet is Chrome. I did not mind even though all the faucet hardware is Nickel- but some may mind.Installation was fairly simple. As I said, I was replacing a Culligan system (allow more time if you are not replacing an existing plumbed system). So, I did not need to drill through my granite to install the faucet (I would get a pro to do that). The existing hole was a little small, but I managed to make it work. My drain pipe and cold water feed was already plumbed as well as my inline to the refrigerator water supply. The main issue I ran into was tubing diameter. Culligan used 3/8" whereas Watts uses 1/4". The 1/4" seems to be the new standard and I actually noticed increased water pressure post-filter compared to the Culligan system. But, because of the difference in diameter, I had to change out some quick connector connections. This is where I would dock 1/2 star from my rating if I could. It turns out Watts does not include a Tee Quick Connector for connecting the system to the refigerator water supply. I am sure Watts did not include it because they figured you already had one or did not want one. In my case however, I had to transition from 3/8" to 1/4". I ended up ordering the part (Celcon Push-to-Connect Tube Fitting, Acetal Copolymer, Tee, Tube OD) from Amazon for about $4 cheaper (free shipping) than my local Home Depot, which did not have any in stock anyway (they wanted me to buy an entire kit).PRIOR TO INSTALLATION I recommend you read the instructions carefully, gather needed tools, and layout all the parts. There are not so many parts that you will find installation overwhelming. In fact, I was left wondering why I had not done this before since it would be cheaper for me to replace the entire system every year instead of having personal service. Installation time to replace exisyting system is about 45 minutes. Without existing system, I would plan for 2 hours.AFTER INSTALLATION be sure to check for leaks after youu turn water on. Check regularly for a few days. I could not detect any leaks with the Watts. Post installation, the Watts requires you flush the system 4 times prior to consuming water from the system. This will take place over a 24 hr period. You simply let the system fill the holding tank and then drain entirely (emphasis added). Repeat 3 more times. I suspect those reviewers complaining of a "plastic" taste upon first use are not performing this step 4 times and/or accurately. Remember, you need to completely drain the system (empty the tank). The first few glasses of water appeared "milky white." This is due to air in the system and is normal. The water is fine (if you let the glass sit for a minute or two, it becomes crystal clear). It went away after two days.SPECIAL NOTES: If you detect leaking from any quick connections, chances are you did not insert tubing far enough. Simply try to push tubing in further- don't be gentle. The noise you hear in the drain is normal during filtraion process. It can be a bit annoying. My Culligan never made this noise, but the Watts is a different design. This noise is the result from water that did not make it through the membrane filter and IS NORMAL for this design.

Watts Premier (531411) RO PURE (RO-4) Reverse Osmosis Filter System - MPN - Watts Premier RO-PURE RO-4The install went smoothly by me the homeowner. The water and ice cubes were outstanding. That was the first six months.Then....The supplied faucet started leaking out a vent hole in the back. Research showed me that this was a known problem and advised that a clogged drain tube could be the problem. Taking it apart proved that the tube was not blocked. The call to customer service included a reply that implied I could not prove the drain tube was not blocked. A supervisor finally got a warranty faucet on the way.The replacement arrived and was installed. The faucet would not shut the water off. Another call to customer service required a supervisor to tell me a special trick (not in the in the instructions) required on the install that did stop the faucet running. The result, A half pot of water for coffee has the sink gurgling for fifteen minutes. Any small usage of filtered water wastes gallons and gallons of water. Did I tell you about our new kitchen floor that got messed up by the leak? This thing has to go. Bad purchase.Update; Six months after installing the replacement faucet, (1 year of ownership) it started leaking with the same problem. The system has now been removed and scrapped.
August 9, 2011

Let us now look at some of its features and compare it to other models.

Features:

  • Filter change made easy on the Watts Premier thanks to the buttons that release the worn out filters when pushed. What’s more, the filters included are specially designed to snap into place once they have been aligned correctly. It is without a doubt that the filter changing mechanism employed by the Watts Premier is the standout feature that makes it appealing.
  • Auto shutoff valves built in the filter heads provide convenience such that the user doesn’t have to manually shut off the water supply to the filtration system once the tank is filled with clean filtered water.
  • The high production semi-permeable membrane of the Watt Premier filters contaminants as small as 0.0001 microns. This mindboggling fact means that 96 percent of dissolved solids and 99 percent of disease-causing bacteria and viruses are flushed out of the water, leaving it safe for drinking.
  • The technologically advanced Watt Premier features a display monitor that lets the user control some of its functions. The monitor doubles as an information center that notifies the user when it’s time to replace the filters.
  • As expected from a top tier RO system, the Watts Premier features a full-sized tank that allows users to store water for immediate use and future use.
  • Features 5-micron pre-filter traps that filter out sediments such as dirt, silt, and rust as well as excess chemical compounds such as chlorine, sodium, etc. in water.
  • This 5 stage filtration system puts out about 50 gallons per day to ensure your family or small business is well catered for with clean, filtered water.

Conclusion

How about the bottom line?

Despite only being a 4 stage RO system, the Watts Premier is a great RO filtration system. All things considered, the Watts Premier easily stands toe to toe with the finest filtration systems despite costing a fraction of the price as the high-end models. This is because it has a lot going for it in terms of usability and features.

Also, the Watt Premier has one of the best filter changing technology in the market. All in all, if you want to consume high-quality water similar to bottled at a fraction of the price and without the inconvenience of bottles, this system will suit your needs perfectly.

PROS:
  • Great build quality
  • Quick change filters at the touch of a button
  • Great tasting water
  • Easy to install and maintain
  • Reasonably priced

CONS:
  • Isolated cases of leaky valve after months of use

Home Master TMHP HydroPerfection Undersink Reverse Osmosis Water Filter System

Home Master TMHP HydroPerfectionUndersink Reverse Osmosis Water Filter SystemFirst impression on the Home Master HydroPerfection is that it does not look anywhere its price tag. For a highly priced item such as this, you would expect it to feature some discerning qualities that separate it from its competitors but it looks average, like most water filtration systems we have looked at above.

However, the sense of touch tells a completely different story. When you touch it and feel it, you get a rough idea of where the money went. From all the RO systems we have tested, the 9 stage filtration system feels the most premium so you could easily forgive its average look. Let us go through some of its unique features below to give you a better sense of this model.

Warranty Description

5 year limited warranty against manufacturer defects

I am not very handy and I was able to install this in about 3 hours. You'll need to go buy a $10 1/2" granite drill bit from Home Depot and 4 wall anchors with screws. The screws that come with this installation kit were not big enough for my needs. Also, check your outlet under your sink. My outlet where the garbage disposal is plugged in is on a switch. That means both plugs are on that switch. You will need an outlet that provides constant power because the UV filter needs to be plugged in.If you're looking for the best tasting water, get this RO system. It re-mineralizes the water. I think it tastes similar to Fiji bottled water and Fiji is one of my favorites. I live in southern California and the water out of my fridge (filtered) still tastes metallic to me. This water is absolutely void of any metallic taste.When I was researching which RO system to buy, I was only interested in the best possible tasting water regardless of price. I'm pretty sure I found it with this system. It is on the costly side of other RO systems but I believe it was worth the $$.UPDATE 9/20/2015: I have had this system for 10 months now. The faucet that comes with the system started dripping to the point where I had to call the company. They said it was covered under warranty for 5 years and sent me a repair kit. As I stated before, I'm not handy. I find this to be very inconvenient. I tried anyway. I ended up breaking the handle and ripping the skin on my finger trying to get the handle back on. My recommendation is to buy a better faucet from the beginning, not the cheap one that comes with it. I learned that you will need a NO AIR GAP FAUCET. I ordered one here on Amazon for $37.UPDATE 12/7/2015: I just ordered the replacement filters and replaced them (Annually). On one of the filters, I did not secure the fitting on the end very well. When I re-pressurized the system, water came pouring out. I shut the system back off and pushed it in a little further and now it doesnt leak. This whole process took about 20 minutes. The ends come off pretty easily. Just make sure you put a towel down before taking any of the filters off or water will be all over the floor.

We installed the Home Master HydroPerfection system in our new home, and are very pleased with the purchase. I am handy, but ultimateley decided to let a plumber perform the installation. The quality of the water produced by the system is incredible. We had a Culligan RO system at our old house, and the difference with the HydroPerfection is night and day. The purity of the water, to our taste, is significantly better. A couple of the things that really stand out for us are (1) the sound - the HydroPerfection is very quiet whereas the other system was constantly making noise in the drain, and was loud enough to disturb TV watching. There is a subtle ocassional noise from the HydroPerfection when it is producing water, but that is all, and it is very acceptable. (2) the flow - the HydroPerfection produces a high volume of water that is great for quickly filling pots for cooking and my Keurig coffee machine. The Culligan system had a very low flow and seemed to run out of water part of the way through preparing for cooking. The last thing is that I can replace the filters myself, and not be dependent on a costly service call to have the work performed. I had questions about the system and Customer service has been great before and after the purchase.

This is my first ro system and I absolutely enjoy the fresh purified water it produces. Just to give you an idea on its performance,I had purchased a tds meter device that measures total dissolved solids. Here are some results of my tap water, ro,costco water,Evian water, filtered water from refrigerator, just to give you an idea. The lower the better. I live in bonita California and the tap water comes out at 550, right out of my faucet. Ro water is 76. Costco water 24, Evian 176. I have been using my system for two days now and there are no problems with the system. I did buy the refrigerator kit and a automatic shut off valve in case the system leaks. This will safe guard my house from flooding. I purchased the additional items from the perfect water.com. I am pretty handy and for the average person it's not a bad installation at all. Cons about the system, for the price I wish they included a nicer faucet. There design can be more stream lined and simplified. One person on amazon said it's like an octopus.lol I think that's exaggerating but I get the point. I love the fact that I don't have to go to Costco and carry those heavy water bottles anymore. I simply order filters on amazon and install them and that's it. I definitely reccomend this system. I will probably write another review after a year of having it.

Features:

  • While the design is not groundbreaking, it is perfectly compact and solves common issues related to RO systems such as ease of fitting and maintenance.
  • The standout feature of the Home Master is its 9 stage filtration system. 98 percent of contaminants such as hydrogen, iron, sulfide, chlorine, metals, rust, and other components are flushed out thanks to the effective combination of a sediment filter, catalytic carbon filter and reverse osmosis purification process.
  • The semi-permeable RO membrane is coated with iron components to protect it from the contaminated water from wells. It is worth noting that the iron pre-filter system of the Home Master is fitted with a catalyst called redox media KDF85 that helps suck all the iron from the water. As you would expect from a high-end filtration system, the Home Master comes fitted with multiple carbon filtration systems that get rid of minerals from the water.
  • Modular filter design in this 9 stage filtration system is revolutionary. Not only does it speeds up the entire filter replacement process but disrupts the build-up of harmful microorganisms in the system. Unlike traditional RO systems that allow you to only change the filters, this unit uses an all-in-one filter and filter housing that is disposable after a period of one year.
  • Since UV light is more effective than chlorine in killing harmful bacteria and microorganisms, the Home Master features UV light technology as a method of sterilization. An added advantage of using UV light is that it does not contaminate the water further as is the case with chlorine.
  • The Home Master features a non-electric permeate pump that enhances the system’s effectiveness by increasing water production by a staggering 50 percent while decreasing water wastage by 80 percent.
  • The Home Master is fitted with high flow components as well as large flow tubes to double the rate of water flowing to the faucet.

Conclusion

To sum it all up:

The Home Master is truly a perfectionist piece of equipment. It is true that this RO filtration system delivers a high quality filtration performance that purifies water better than most filtration systems. The thing about the Home Master is that, you don’t only get germ-free water but you are guaranteed odourless and great tasting water with added minerals.

The odourless, mineral-rich water is made possible by the Home Master HydroPerfection coupled with other cutting edge technology. Perhaps the only stumbling block with this model is its super high price. Unlike some RO filtration systems, the price of the Home Master is justified with technology such as UV light, the non-electric permeate pump and the all-in-one modular filter design among others.

So if price is an issue for you, you are better off looking at other alternatives but if it is not an issue, you will get back every cent of your investment through the Home Master’s performance.

PROS:
  • UV light technology
  • Easy to change filters
  • Fast flow rate
  • Water efficiency
  • Great build quality

CONS:
  • Expensive

I got this to replace my old under sink filter. I was a bit worried because my old unit came with its own mini pump and was unsure if I would get as much water. But I get as much if not more, at half the cost. Now if it will last as long, just over eight years, I will be happy indeed. The only problem I see that someone that is not very handy might have is the picture diagram instructions. But if you take your time and trace everything you should have no problems. Oh! One more thing there are a few screw in, or on hose fittings that you may need to add some Teflon tape to, 2-4 wraps. They come with some but mine had so little that they leaked. OK just one more thing, the hose fittings are push in types. Make sure you push them in all the way.

The customer support is exceptional. Call or email and question and it is answered quickly and professionally. I looked for a reverse osmosis system for three months evaluating them all and glad I went for the GlobalWater system. It has the best price for the best product.Ron

The instructions are TERRIBLE! The outlet fitting was broken when it showed up as well. Having said that it is a VERY complete kit at a great price!I suggest you watch this video for instructions. It isn't quite the same kit but close enough:[...]After replacing the fitting with a part from the home improvement store I was able to install the unit in about an hour with very basic hand tools. It leaked from the threads on the tank but a few wraps of teflon tape fixed that. I've had it for about a week and it works great!

Features:

  • 5 x 14 x 16 inches in dimensions with a weight of 17 pounds.
  • An NSF compliant sediment filter (5-micron) that effectively filters away large particles such as mud and sand.
  • A GAC carbon filter (10-inch and activated) that serves to remove dissolved organic substances as well as chloride and fluoride components giving the water a nice odor. Any color particles and chemicals are well dealt with by this filter.
  • One CTO carbon filter (5-micron) that removes the cloudy property of unpurified water. This filter restores the sweet natural taste of water.
  • A semi-permeable membrane (TFC), which filters away over 1000 pollutants before being disposed down the drain. Unwanted elements including dissolved minerals with negative health impacts are filtered by the membrane. Other remaining amounts of chlorine, fluoride, VCO chemicals and organic solutes are filtered too.
  • One inline filter at the final stage of the process where unwanted smells and unnatural tastes are removed. This cartridge fits easily into the system.

Conclusion

Global Water RO- 505 system is one of a kind. As if the fact that its USA made fittings are durable is not enough, the buyer gets a free spare of all filters for free. It has never been better. The effectiveness of the system in giving households water that is not only sweet but also healthy.

PROS:
  • Global Water has been the water business for a long time. This system is, therefore, designed and made with years of experience to offer the best possible service.
  • The RO-505 system filters 99% contaminants after five stages in the RO process leaving you with clean, sweet, odorless water.
  • The NSF faucet, colored tubing, and NSF steel tank are very durable. Further, the components are lead-free.
  • This system has Water Quality Association (WQA) certification. This means the buyer is assured 100% satisfaction with minimal usage frustrations.
  • The sediment filter and three carbon filters that make up the system come in double. This means that after the installed ones wear out, replacement can be done without much hassle. The system also affords self-shutting valves.
  • Installing the system at home is easy. The system comes with an installation kit and easy to follow instructions that cover the entire installation process.
  • This system comes with no batteries and requires no batteries to run. It uses pressure instead.
  • In case of any problem either during installation or during usage, the customer service of Global Water is available round the clock.

CONS:
  • The efficiency of the system is low. A relatively large amount of water is lost during the RO process (ratio 3:1)

Warranty Description

5 year limited warranty against manufacturer defects

I will give you the bottom line up front - WE LOVE IT!Although I live in an area of Michigan with pretty good water quality, after the Flint Water Crisis, we became more cognizant that things can go wrong without anyone realizing it for quite some time - with the damage done. So began our journey to the Home Master TMAFC Artesian Full Contact Filter.My Girl is always reading up on the latest health news and trends. And while a lot of it is helpful, sometimes she gets to thinking about things that I am not sold on: Fluoride.She has become one of those that believes Fluoride is bad for you, that it acts as a poison, and hampers proper function of something called the Pineal Gland. I will spare you all the rest of the discussion, let me just say that at this stage of life, I find it easier to just give in some times and not fight it. So, even though I am one of those that believe Fluoride has done immense good for America's kids by reducing cavities, I am at the age where my teeth are fully developed and I am not worried about cavities anymore. So she began to buy and drink ONLY bottled water.After her first month of spending a King's ransom on bottled water, I decided to investigate to see if I could bring some better solution to the table. At my local Better Health food store, I discovered that the latest trend was not only bottled water, but PH water. I researched the issue, and understood the logic behind it. So I told her if we are going to spend a fortune on bottled water, we might as well do the PH positive thing and gain the health benefits of that as well. So over the course of three days I purchased 28 various brands of bottles water - from local grocery store brands, to the very high end waters. Then I performed a PH strip test on them all. I was shocked to find out that nearly every water that advertised itself as PH high (with a few exceptions) was lying. The brands that rated the highest numbers were Perrier and Crystal Mountain (from Michigan). To ensure that I was correct in my thinking, my ex father in law, the former Head of Chemistry at the University of Minnesota, said that any water should be testable with test strips - to within a half PH number or so. That was good enough for me. Yet, I knew that paying for these would still be a costly and cumbersome solution. So nearby, I found a store that sold purified water. Sort of like a Deer Park, but one that you bring your containers there and pick up the new ones yourself. The savings over a home delivered one was huge, and would have been much better than buying bottled water by the liter or less. Guess what, his PH water tested the same as tap (7)- after he had assured me that he had tested that morning with a PH of 9. I figured that if I couldn't trust him with that, that I couldn't trust him on any claim of additional purity over tap.So then we began our research into Under Sink Water Filters. Because of my experience with the famous brand waters, as well as the local water business guy, my trust in any company's claims was shot. So I researched numerous third party sites that tested various filter's water, and narrowed it down to three - which included this one. One was much more expensive, and one about half. I read EVERY Amazon Review, Question, and Answer for each of the three. I was pleasantly surprised to read that the data on Amazon coincided with the data from the third party sites; and that all three finalists seemed to be good honest solutions.In the end, we chose Home Master because we wanted a Mineral Water not just Purified Water. We also a positive PH level. And finally, the under sink set up seemed to look ideal for our existing under sink world. I figure the money I spent on the Water Filter system would pay for itself in a year or so, instead of buying bottled water.Although we already had a hole drilled in the counter top, where we had removed a failed hot water tap for tea/coffee, I had the wisdom to not try to install it myself and had my plumber brother in law do it. Excellent move on my part. Although I had measured the space for the water tank properly, I had failed to account for it slipping under the existing disposal and its plumbing. In short, the tank wouldn't fit, nor would the filter assembly in the place it really needed to go. So my plumber took out the disposal, put the tank in, and re-routed the existing plumbing so that our Home Master could fit. Perhaps many homes don't have this problem, but I did, and am so glad to have had a plumber do it. It took him around two and a half hours to install. Afterwards, I read the directions and ran the system flushing operations three times to get the water quality where it needed to be. I measured that it took an hour and half to refill my tank, and it would take six minutes at filter tap full on to drain it. Good to know for future reference. Your numbers may be different though.So, since then my girl and I love the water, it tastes great - as good as any bottled water out there. And I am confident that it is filtering out the stuff we don't want while providing the minerals and PH we do. My cats seem to love it too, although i do plan to conduct a test with them, where I put regular tap water next to the Home Master water and see if they really do prefer the filtered.One final thing. My gal did not like the faucet style that came with the unit. So we found another on the company web site she did like. We ordered it from the company and it arrived and looks great. During the whole process - just before Christmas - we spoke on the phone about three times with Customer Service and found them to be absolutely professional, knowledgeable and friendly as can be. I could not have asked for a better experience.So, if you want my recommendation. For a reasonably affordable unit for a couple this unit is a no-brainer. Yes, you can cut corners and get something about half price - but that won't give you the mineral water element, and in fact will raise your acidity. And Yes, you can spend over a thousand bucks more and get a very nice filter, but why do it you can get the same quality here?

OK, We have had a prior RO which died and was discontinued by another manufacturer, we never had decent flow with this prior unit. We then spent time looking at all the highly rated systems on Amazon and on the internet. We initially tried a different brand that was rated for up to 500 gallons a day, had it's own integrated electrical pump, and was advertised to handle home up to small cafe. That unit was really pretty, but again despite being able to produce a lot in one day, it's flow when you opened the RO tap was similarly slow to our our prior unit, and if the integrated electrical pump was not on, forget about it, flow was at a trickle. That is the other issue that it takes about 10 or seconds for these systems with the integrated electrical pumps to register the demand before they kick in an really start providing any flow.Well I was drawn to the Home Master system being that it states that it provides twice the flow of other systems from use of among other things larger 3/8" tubing rather than 1/4". In addition to that the system has a permeate pump which is a pump that uses the hydrostatic flow of the water to generates increased pressure, decreases waste water and increases flow all without the need to run electricity to it. It works somewhat to a turbo system on a car spinning a flywheel with the flow, but without the turbo lag. The Home Master systems also come with integrated filters and filter housing that you simply replace as a unit every year. The thinking is that filter housings also wear out over time, and this way as replacing it as a unit, you don't need to worry about wear on the housing and their gaskets. In addition to this the Home Master systems come with a five year warranty. I will say the systems esthetically are not much to look at, the other system we tried had an integrated frame everything mounts on, but who cares this system gets it done. Additionally this system mounts to the sidewall of a cabinet on a bracket and takes up much less space than most of the other systems out there.This particular Artesian system replaces minerals such as magnesium and a little calcium that are leeched out during the RO cycle so the water doesn't taste flat like distilled water of most RO systems, but tastes like mineral water like Fiji water. So how pleased am I with the system? I can't say enough good things about it. I thought the instruction manual was just so so, but the manual directs you their on line videos where installation is broken into multiple short easy to follow installation videos. The water flow out of the RO faucet is astounding! It literally fills a 12 ounce glass in two seconds. All with the same house pressure that our prior and the other system we tried gave only a mediocre trickle.I did call Home Master's 1-800 number and they were very helpful in choosing the right one of their systems. I obviously feel that if you are looking for an RO system with great flow, great tasting water, ease of upkeep with a low profile that this is a great system to consider.

I have been using an RO system for 20 years (first with a well & now on city water) and have appreciated the quality of water, the coffee pot that runs forever without problems and the refrigerator that produces perfect ice cubes. Recently, when our old Kinetico unit failed I started to look for a replacement. I was inclined to just replace the worn out parts on the old unit, but common sense prevailed and I purchased the Home Master unit. Repair parts and filters are readily available on Amazon and their Support team is excellent.Our unit was installed with the Home Master Permeate Pump (ONLY USE THIS OEM PUMP) and was mounted in the basement just below the kitchen sink (see photo). After a little checking this was the best location considering future maintenance and to free up the space under the sink (note: we have 60 PSI water pressure). After getting the installation schematic (see photo) the process went quickly and the push connectors worked well. I also purchased extra tubing and the refrigerator kit.A bonus is the new unit fills the capacity tank much faster and the faucet flows maybe 50% more than the old unit. Because this is a new installation I cannot speak to reliability, but will try to update these comments in a couple of months.

Features:

  • Full Contact technology adds two minerals at separate stages during the purification process. Magnesium and calcium are added at the rate of 30-60 mg/l. The resulting water is healthy and without acidity. Slightly alkaline water is tasty.
  • The Modular Filter design is an innovative way to do away with the problem of canister filter housing. The new design combines the filter in a filter housing that is easy to change. Otherwise, the debris filtered during RO accumulates in the canister and weakens it. Eventually, it starts leaking, causing wastage.
  • A catalytic carbon filter, which filters away very resistant contaminants such as chloramines, which common carbon filters cannot filter out.
  • A non-electric permeate pump that enables the production of 75 GPD. Further, the pump reduces water wastage to a ratio of 1:1, which is 80% lower than traditional RO systems. It also increases the flow rate.
  • A Fast Flow RO kit that avoids slow flows. This system uses tubes that are slightly larger. This, combined with the power of permeate pump, ensures fast flow rates.
  • The system measures 12 x 16 x 20 inches and has a mere weight of 14.5 pounds. It comes with a whooping five-year warranty from the manufacturer.

Conclusion

The Home Master TMAFC-ERP performs seven-stage purification process that gives the best quality of healthy water. The fact this system gives mineral water directly from the faucet is through the Full Contact Technology simply excellent. Its pump ensures slow flow rate common in other RO systems is well dodged.

Our opinion is that this is the best candidate among competing systems of its kind.

PROS:
  • The 7 stages of filtration remove as much as 99 percent of pollutants and contaminants. Persistent pollutants that common filters cannot remove are filtered as well. TDS creep is also eliminated.
  • The Full Contact innovative technology adds magnesium and calcium to clean water. This makes it even healthier, odorless and alkaline. Other than being pleasing to the tongue, alkaline water does not corrode the tank as acidic water does.
  • This system is just a snap to install. Its parts have the fit-in quality and no tools are needed to get it running.
  • The fittings of the system meet NSF standards.
  • The filters can produce over 2000 gallons before being replaced.
  • The TMAFC-ERP is an efficient system and has very low water wastage rates at a ratio of 1:1.
  • The system is relatively affordable and requires little maintenance.
  •  5 years manufacturer’s warranty.

CONS:
  • Some customers have complained that the installation manual is more confusing than guiding. This problem has been addressed by incorporating images in the manual.
  • The tubing may be inadequate to cover a large place. However, an extension may be bought and the problem fixed.

I researched these systems for a few weeks (on Amazon and talking to my plumber and associates at Lowes/H.D) and finally decided on this system. For starters, this system is packed very well and arrived to my home completely intact. I was impressed upon opening it as the main filter housing unit seemed very high quality and heavy. The unit ships with a filter in each of the three compartments as well as an extra set of filters (excluding membrane).Whether this system is easy to install or not is obviously subjective depending on factors such as the your previous experience with basic plumbing and/or your particular location for install. I decided to install mine under the kitchen sink and also ran a separate line for the refrigerator's ice/water line. More on that in a bit.The included faucet is satisfactory and works better than I thought it would. You can push the lever down and hold it if you just need to fill a glass or you can flip it up until it locks and and it will continually dispense until you turn it off. Another neat thing about it is once you bolt the base of the faucet down, you can still swivel the entire neck around so you could, for example, fill the dog's water bowl with it sitting on the kitchen counter next to the sink if the sink is full. The finish of it is a shiny chrome, and it matches my new Moen stainless faucet well enough. However, I may replace it in the future if my boss (wife) requests it or if the mood strikes.You will need to drill one 1/2" hole to mount the faucet. I couldn't find this info anywhere prior to ordering the system, but I was very happy once it arrived. Some of these faucets require a 1 1/2" hole, and that would concern me because I have a synthetic granite/composite sink that it tough as nails to drill into. If you need to drill into granite/marble, get a bit such as a Lenox diamond tip whole saw bit (1/2" bit) It will cost you about 20 dollars and you can buy it at the big name blue or orange home improvement stores.TIP: Once you locate where you want the faucet mounted, get a thin piece of wood (such as a shim) and drill a 1/2" hole in it. Then get some duct tape and tape it onto your sink where the hole in the wood is directly where you want the hole for the sink faucet. Then drill through the hole in the wood into your sink's surface. This will keep your drill but from "dancing" or walking on the surface. Also, take your time!! This is a crucial step and you don't want to screw it up. The key is using the proper drill bit for your application. In my case, it took me a good ten minutes to drill through my sink (probably a 1/4" thickness) and the bit was completely useless once I got through the surface. In other words, I just made it. Also, don't be afraid to get an eye dropper or baster to drop water in the hole as you're drilling. It will help your bit to not burn up so fast. Once the hole is drilled to your liking, follow the illustration for assembling the hardware for the faucet and mount it.The actual hook ups and plumbing for the system is where I kinda did my own thing. I have a 2200 square foot ranch that was built in the eighties with that nasty, defective polybutelene plumbing and, after a ruined master bath and another close call in the kitchen after owning the house for just 6 months, I had my plumber completely re-pipe to the tune of 5K. So I guess what i'm saying is I am not fond of cheap plastic ice maker line, or the plastic inserts or nuts. The good news is because all of the fittings on the system are 1/4 inch connectors, you can use the fancy braded chrome ice maker lines with the compression tips that would normally go behind your refrigerator to hook up most of the system. If you decide to do this, the only one you won't be able to use one on is the yellow line that goes from the RO unit to the tank (because it has a crimped-on special two-way valve). One word of caution though- if you do this be very careful and mindful that you are screwing a metal compression connector onto plastic threads on the unit. My advice, in hindsight, is to determine where you're going to want the unit and place it there prior to beginning the install. Then determine what lengths of lines you will need and hopefully you will only have to screw the hoses onto the unit one time, as opposed to screwing a 5ft hose on the unit only to realize that you only needed a 2 ft hose and then having to unscrew the connector. If you want to incorporate your icemaker line, you will need a 3 way female 1/4" T connector, one for the fresh RO water coming in, and then two lines-one for the RO faucet and the other for the ice maker.Bottom line is-take your time!! If you do, you will love the result. It took me longer than it probably would have taken most people, but I have a unique kitchen sink with funky plumbing (couldn't use 1/2" adapter included to feed system from faucet bottom, instead had to convert down to 3/8" and run from cold water valve).Oh yeah, the water tastes amazing!! I would be the first to tell you if I didn't think it tasted good but it is phenomenal! I am a coffee drinker and the coffee tastes so much better! It also tastes better than the bottled water that we buy. It's like the water has absolutely no after-taste. It's just pure H2O! Feel free to email me at mcneil2348@yahoo.com if you have questions or want to see pics of my system in action!! Good luck!**UPDATE** 6-15-2014The system has been in now for two weeks and we're very impressed. My wife, who typically drinks coke or sweet tea, is literally drinking 2-3 large cups of this water daily! She absolutely loves it! I went to a Mexican restaurant last week with my boss and ordered water with my meal (which is what I always drink) and I noticed immediately how horrible their water tastes now! I never noticed it before until I started drinking the APEC water.As far as reliability goes, I have not had any problems or leaks with any component of the system, and we are using it rather heavily. We also have a baby due in 9 weeks so we're looking forward to making baby formula with this great water, too!

No more carrying 40 Lbs water jugs. What we don't like about the filter is that it wastes 3 gallons for every gallon you get, just goes into the sewer. We love the convenience of not carrying heavy water containers.The taste is amazing. Here in Las Vegas we have hard water. We have tried other water filters without the success we achieved with this filter. To us it's well worth the money spend.We bought a TDS meter to test the water. Results:faucet tap= 328ppmaquafina bottle water= 2ppmkirkland (Sam's Club bottle water) = 20ppmand the apec water = 25ppm

I bought this system to replace the pre-installed water filter in my new home. The builders system was installed by a local company, filters are proprietary and $125-150 per pair, every 6 months. Instead of paying that much for a two stage filter replacement every 6 months, I looked for alternatives. I decided on the APEC after the glowing reviews and Built in USA tagline. What isn't immediately clear is that only 3 of the filters in this system need replacing every 6 months, for around $25 in total. The other 2 only need to be replaced every 2-3 years. Not bad in my opinion.It took me only 30 minutes to install the system, as I already had the extra drinking water faucet installed, 1/4" tubing, and quick disconnects. The only thing I had to install was the drain valve, by drilling into my waste water pipe. When you do this step, its imperative that the hole drilled lines up well with the waste water clamp hole. After drilling the 1/4" hole into your PVC drain, I recommend holding the clamp with one hand and inserting the 1/4" bit through the clamp hole and PVC hole you drilled. Tighten the clamp with the included screws and then remove the 1/4" bit. This should leave you with a perfectly aligned waste water clamp.After the clamp was installed, the rest of the process took about 10 minutes. I setup the entire system and slowly restored water pressure back to the system. I waited just over 2 hours and drained the water tank as described. Here are my TDS measurements in PPM:Tap Water: 270Builder's 2-stage system: 217Fridge Filter: 170Ozarka Natural Spring Water: 28Smart Water: 22APEC Water Filter System: 8 (yes, that's eight)It does take up quite a bit of space, but not as bad as I was thinking and certainly well worth it. This system fits underneath my sink along with the mega InSinkErator Evolution Excel, with room left over for cleaning supplies.

Let us take a look.

Features:

  • A 5-micron sediment filter measuring 10 inches that filters away sand and rust.
  • A 10-micron carbon filter measuring 10 inches, which takes over the second stage. VOC chemicals and organic solutes are filtered by this filter. Similar filters are placed at the third and fifth stages to remove more pollutants and unwanted water color particles and odors.
  • The system has one TFC semi-permeable membrane where most of the RO process takes place. Contaminants that do not pass through are washed down a drain pipe while clean, fresh water goes to the fifth final stage.
  • ROES-50 features the double carbon blocks with a larger than normal surface area. The effectiveness of these two blocks is unparalleled. They give a 99% purification level, leaving perfectly clean & safe water.
  • A rate of 50 GPD, which is ideal for smaller households. This rate is attained at 60 PSI.
  • A lead-free chrome faucet to safeguard health. All other parts are lead-free as well. The tubing is FDA approved.
  • The system measures 16 x 5.2 x 17.5 inches, overall weight is 25 pounds.

Conclusion

And you know what else?

ROES-50 fittings have the Quick Connect technology. Installing the system does not require the expert services of a plumber nor does it call for a powerful wrench. The parts fit well and the system works in less than thirty minutes.

What’s the most interesting part?

The best thing about APEC-Top Tier Five-Stage RO system is the quality of its fittings. They are all American made, very durable and guarantee high performance.

I was looking for a reverse osmosis water filter which doesn't waste too much water ( I live in the California - the Drought Stricken state ) I was leaning on to watt's zero waste system but i didn't like that it actually doesn't really save water, but it just redirects the waste water to the hot water pipeline using a pump. I was worried about the high back pressure causing any leaks or damage to plumbing. Finally saw this one in Amazon and thought I will give a try with this.According to the comparison charts they have, this one wastes much less water than other Reverse osmosis filters using their own technology ( that I don't really understand . I am an Engineer, but not a mechanical engineer. And the documents they have published online was not really something I could digest with my brain.Anyway, I got the first one, and while trying to install we noted that the intake shutoff valve that came with the unit was broken and I will not be able to use that at all. I contacted Amazon customer service and they readily initiated a free return and advised me that I could re order another one.The next one I ordered was luckily a good unit. I am not very good with tools, but the installation took me just about an hour, including unpacking, setting up, drilling the hole for the waste water and even fitting the faucet in the extra hole we had in the sink. And once I turned on the valve, in about 40 min the tank was full. As told in the instructions, I drained the water and allowed it to fill again, and then the tasted the next one. It was really clean and crisp. I almost had forgotten how good water tastes after having the hard water being filtered with just a Brita filter. ( Brita is good, but after just couple of days, the hard water tastes will popup until the next filter change, so was not really a good way for drinking water. )Its been a month since I had this installed and so far no issues at all. We use about a gallon of water per day for drinking. ( I don't really care about the extra calcium in the water if I am not drinking plain water. )Pros:- NO need for electricity., but still works perfectly with the water pressure/the ballon inside the tank giving a nice flow of filered water whenever needed.- Easy installation. If you already have a hole for the faucet, then all you need is an adjustable wrench and a drill to fit the waste water connection.- One box which looks good. But I dont really care about the looks. its anyway under the sink. Being it all in a single box helps avoid other stuff getting stuck between the filters etc. but no big deal.- Nice clean tasting water. NO more hard water taste.- When compared to other Reverse osmosis filters, very less water wastage. ( I haven't really measured it yet, but I plan do do it sometime soon. The waste water line is connected to the drainage via a easy fix connection, so its easy to connect it to a measuring jar and measure how much it is really wasting.- Cons:- The intake shutoff valve which goes to the cold water connection has a very weak link. The handle which is very tiny, which controlls on/off positions is like very fragile. If you plan to use it many times, I am pretty sure it will break soon. I had my first one already broken when I got the package.They should definitely have a better QA Process for this to make sure this kind of issues never happens. Or may be even recall the part and send a replacement with better design to all customers.- Not sure whether I can buy the replacement filters from any other manufacturers. In case they stop the model and parts, I am not sure what to do. However I think thats probably true with other RO filters as well. I am not very familiar though.- Even though it is a single box, it sitll is pretty big. I could just fit it barley under my sink. I wish they come up with a smaller sized model as well. This one has a 6Liter capacity for filtered water, but may be they can come up with a 4 liter ( about 1Gallon) capacity, as smaller families only need that much. And it takes only 40 minutes to fill it again. so if you are using it primarily for drinking water, we can always have a water pitcher outside. Also it helps to have a smaller size for people with less under sink space.UPDATE: 4/4/2016:The unit is still working as good as new. Clean tasting water so far. I use approximately 1 gallon of water per day on average so its not yet time for replacement according to the recommended replacement cycle for any of the filters.I did finally get some time to test the actual water wastage. Today, I made sure that the tank is full and then disconnected the waste water outlet and put it into my own bucket. Since the tank was full, no water was coming out of it at all. Then I filled my water jug ( 2 quarts ) and a water bottle ( about 600ml ), so approximately 2.5L ( 2.6Quarts ) of water was taken from the tank. The filter started filtering and filling the tank immediately, and the waste water started coming out. After about 20-25 min or so, it stopped competely. And when I measured it came to approximately a little less than 1.5Gallon.

I like the unit, the single monolithic design definitely keeps my under-cabinet area less cluttered. That being said, the QA on this thing needs some improvement. I installed the unit, and when I turned on the water source there were leaks everywhere -- top connectors and internally! I had to take the unit out to address the quick connectors. The ones internally - the lines weren't pushed in completely into the connectors which is why they were leaking. The top connectors, one was my fault (did not push the tubing all the way in) the other one was faulty. Fortunately, the parts are just off the shelf and can be found at the big box stores. Overall, I am pleased with the unit, but I do find the water flow from the spigot to be a bit slow. I've had other RO systems that provided quicker dispenser filling, but I think those reserve tanks had compression bladders, I don't think this one has that feature. Water that is produced is great. FYI, Since there is not a final mineral bed stage (to add trace minerals back), the water might taste a bit sweet/strange at first.
January 5, 2016
Overall a great product. Clean modern design and works well. I have been getting readings on my tds meter of 6 ppm- 23pmm.The flow is also good for the size tank. Fills up my gallon jug pretty quickly. Although the internal tank is only 1.5 gallons I have been using it for two days without running out. We use it for our babies bottles mostly.I have limited under cabinet space and this is exactly what I needed. I have had RO systems before but always for my fish tanks. They have tubes running everywhere and a big tank.My one gripe with the system is that the 3/8 adapter for the cold water inlet seems to have been engineered wrong or at least for my type fitting. The inner whole doesn't seem to be beveled out wide enough to fit the water line.I called customer service who was very helpful and are sending me a new part. Also they said that the next batch will include this change part.

Features:

  • This system features the all-new Water Saving Smart Technology which reduces the water wastage to a 1:1 ratio.
  • Three filters that work efficiently through four RO stages to clean up fluoride (over 80%), chlorine, arsenic and VOC chemicals. The carbon filters have large surfaces to maximize their contact with water and purify it fully. It is worth noting that filter spares are readily available from the manufacturer.
  • An NSF certified lead-free chrome faucet. The faucet features an innovative design to increase reach.
  • LED lighting is integrated into this RO system. It turns on when being used. This makes diagnostics very easy.
  • Brondell H2O+ Circle is fully dependent on pressure. It requires no new source of power such as electricity or batteries. Further, it requires no inbuilt pumps used by other systems to increase efficiency.
  • This is one of the smallest RO systems in the market. It has a modest size of 13.8 x 9.2 x 16.5 inches and carries a weight of 14.6 pounds.
  • The system can handles pressures of 120 PSI to give a high flow rate of 0.37 gallons per minute.

Conclusion

Can we be totally honest with you?

To say that Brondell H2O+ is a classic beauty would be an understatement. We feel that this system beats other systems by far. The small size, a weight of 14.6 pounds and the beautiful design are simply exceptional. The Water Saving Smart Technology ensures that users get the minimum possible loss. And while others may complain about the price, this system is worth every penny.

PROS:
  • The system is extremely efficient. It saves water more than other systems of its class.
  • Space on the under the sink is preserved as much as possible; it is left spacious and neat. Further, the all in one design keeps the filters, tubing, and storage tank well protected from physical damage.
  • Clean, healthy, tasty water is guaranteed by this RO system. It removes a great percentage of contaminants and TDS creep, leaving readings of below 10ppm on the TDS meter.
  • It features an auto-membrane flush. This lengthens the life span of the membrane.
  • The above 50 GPD is optimum for a household or a small business.
  • Swift installation- the filters are just twisted and pulled so as to be removed. No need for tools.
  • One year manufacturer’s warranty.

CONS:
  • The system is relatively expensive compared to others of its class. The design and functionality justifies this pricing.
  • The joint of the faucet consists of cheap plastic that may break after months of use. This problem can be avoided by taking extra care when using the faucet.

A lot of good descriptive reviews here, I'll add mine here but will focus on my perspective as someone living in Israel.Israel is an arid country which in recent years made a big transition to desalination. The national water company (called "Mekorot") is using >50% desalinated water from the Mediterranean Sea mixed with about 25% water taken from the Galilee sea (which is actually a fresh water lake) and the rest comes from mountain and coastal plain aquifer. Water then travels in the "national conduit" to various regions in Israel.The water in Israel are heavily treated, mostly because the national conduit is an open system, i.e. water travel in big pipes that are open to air and elements (e.g. rain water), but also because aquifer can become polluted with industrial waster and fertilizers, so does the Galilee sea.Also chlorine is added and recently fluoride as well. not to mention whatever is picked up from pipes until it reaches the kitchen tap.Local mineral water companies (with strong brands) draw from fountains in mountainous areas and bottle onsite, but are exposed to the same contamination of aquifer. For instance, one very strong brand I examined had 3 times of what considered (in the U.S) the max safe concentration of nitrates.I hope I'm successful so far at convincing you why water filtration is important in Israel.Now comes the question, what are the options? for most people in Israel who don't want to research too much it's these:1. water pitcher filters, like Brita2. Tami4 - a water bar that combines carbon filter with UV lamp3. bottled water, e.g. mineral water4. there are some local vendors who install advanced water filtration systems like Everpure or some Reverse Osmosis systemsNext, why I think all of the above options are either not sufficient or cost effectivewater pitcher filter - relatively cheap but only filters chlorine and stops some sediments like dust. you're still exposed to a lot of chemicals and heavy metals in the waterWater bar vendors - VERY high initial investment (~$1000) and high maintenance (~$150 year), not to mention if their equipment breaks you have to pay for repair. Also it's merely a carbon filter with a UV lamp, with some cold/hot function. I really don't think it's worth the money, especially since the UV lamp is there to kill the germs that grow in the machine itself. important to realize the due to the chlorine and UV treatment by the national water company, small chance of bacteria to survive in Israel's normal tap water.Bottled mineral water - relatively expensive, need to carry from supermarket, or pay a monthly fee to the vendor to deliver to your house. Also not eco friendly (plastic), exposed to aquifer contamination (almost zero regulation and testing by government) and some say under heat conditions plastic can dissolve into the water.But most importantly, from TDS meter readings I've made, tap water and mineral water have the same TDS levels, while unlikely that healthy mineral concentration (e.g. calcium, magnesium, potassium) is any different. In some brands mineral water TDS was even much higher than normal tap water.Local Reverse Osmosis Vendors - at best they are importers who lock you in high maintenance fees. worst case they import cheap chinese systems. You pay a premium for them to import, install and maintain the system for you.I chose APEC RO-90 after hours and hours of research. It's very important for me to say APEC did NOT ask me to write this review and I'm doing it because I think their product and service is amazing and I'd like to give back.Even after shipping and Israeli customs fees, the RO-90 was cheaper and more cost effective than any of the alternatives I specified.What I really like1. packaging was excellent and the product is robust, The system was intact and I had no worry about that.2. installation was very easy, everything just connects beautifully. I installed it in a few hours (I like to read the manual very thoroughly)3. water tastes great, even my pregnant wife who is very sensitive to tastes said she liked it4. TDS went down from 260ppm (tap water) to 15ppm (after RO-90 treatment)5. the included tap is elegant and fits nicely on our kitchen counter6. system is VERY quiet, can't hear it7. customer service is really good, I already talked to them twice about questions I had, they respond really quickly and their reps are knowledgeable.8. maintenance is cheap considering the other options, and I have full control over the process.What I don't like1. the installation guides needs to be more specific about first run - you shouldn't drink first 2-3 tanks, open the tap and let them drain.2. the feed water adapter should come with more options, I had to buy 1/2'' to 3/8'' adapter to make it work with my pipes - cost me another $10What still needs to be tested1. my water bill, but I checked in my house water gauge that the system stops working once the tank is full, so I'm Ok for now.2. TDS measures at 15-25ppm at the moment, customer service promised it will go down even further, although I'm fine with that level as well.All in all, I'm am very happy with this product. water quality is excellent and it gives me peace of mind I've made a cost effective and healthy choice.Final note:During my internet research on the long term health concerns of reverse osmosis water I've made some interesting discoveries. This is a long subject and I believe I researched it well enough to make an educated decision. I'm tempted to post my thoughts about it here but this review seems long as it is. perhaps some comments might convince me to update this review with some key learnings. For the time being I would like to say this:Almost all resources you'll find on negative long term health effects of reverse osmosis water are based on the World Health Organization research from the 80's. That research had some notable flaws in it and it tends to dramatize concerns. I believe that for people living in western countries and use home reserve osmosis system most of those concerns are not relevant. Reverse osmosis water are safe to drink, especially if you consider the alternatives.

I had a really old RO system that my parents bought long time ago. Every year, we pay a service guy to come a replace the filters for us and each time he charges around $60 to replace. If it requires a membrane replacement, he will charge us around $150! After 10+ year of usage, I figure it’s time to change to a new one. At first I was thinking about getting a newer unit from the same company but my friend told me that I should just maintain it myself so I don’t have to pay for the ridiculous service fee.This is when I heard about APEC Water. He said that their systems are very well built and also the filters that they use are the best in the industry. When the system arrived, my initial impression was wow! This thing is night and day compared to not just the old system that I have before, but the new system that the same company is trying to sell to me. The craftsmanship and quality of materials even down to the way it was packaged.The whole installation took me about a good 1 hour because I want to make sure I got everything installed correctly. The hardest part was probably the faucet installation, because I had to crawl underneath the sink cabinet and it is not fun for a 6’-1” guy. Other than that, the system installation itself was a breeze. I would say, as long as you follow the instructions on the manual, you shouldn’t have any issues on installing it. Overall, I would give it a 5 out of 10 in terms of difficulty and most of that 5 is coming from the faucet installation.Out of curiosity, I took my old system apart to see what filters they used, and surprise; they don’t even have a brand, not even on the membrane itself. Now I know where most of my money was going during its service. With this new system, I pay only $39 a year for top notch filters and it also come with a nice tester for me to monitor the quality of my water anytime!

We have a well in our new house that has elevated arsenic (0.020) and radon (15,700). The radon is really high, the arsenic is twice the acceptable limit.We installed this unit and had a arsenic and radon test done after the install. Our arsenic went from 0.020 to 0.0001. Well less than the 0.010 acceptable limit. Most impressive is the radon results, from 15,700 down to

Features:

  • To start with, this system features 5 stages of filtration. It aims to produce ultra-safe water with 99% less pollutants.
  • The product measures 15 x 7 x 18 inches and has a weight of 25 pounds. This weight is justified by larger than standard filters.
  • It consists of three filters: a 5-micron 10-inch sediment filter and two carbon blocks (5-micron 10-inch filters) that takes over the first, second and third stages of filtration respectively.
  • Incorporated in the system is TFC membrane with a high rejection rate where unwanted dissolved substances are filtered out. Components such as arsenic are reduced to 0.0001
  • One TCR carbon filter on the final stage of filtration- the filter takes out persistent smells and taste to give sweet, clean, healthy water.
  • Other than the lead-free faucet, all other components are NSF certified.
  • The filters of this system are super capacity filters. This means that they fill up slowly and maybe used for an extended period of time without change. Typically, they last twice the normal lifespan of a filter.
  • This system has a one year warranty from the manufacturer and has WQA certification.

Conclusion

Can we tell you a little secret?

APEC ULTIMATE RO-90 is a top-notch system in the market. Its durable USA made fittings and a production of 75GPD are nothing but a deal breaker. With this system, a homeowner can be sure that the family is getting nothing but the best water (ultra-safe).

It is very economical and its price is fair.

PROS:
  • WQA certifications guarantees trouble-free usage. The system works with minimal noise.
  • The system is effective. It purifies water to an ultra-safe level, unlike normal RO systems that purify to a safe level.
  • The filters are the USA made, are premium and last two times the lifespan of a normal filter.
  • The production of 90 GPD is not only suitable for the large household but also medium-sized business.
  • The installation is a DIY activity. An hour is enough to begin drinking healthy, ultra-safe water
  • Includes Quick-Fit mechanism that securely fit to avoid leaks without any additional tools. It is NSF compliant, while the tubing is FDA compliant.
  • A customer service team is always available to offer assistance when a problem arises. The team has adequate technical know-how to pull through the tough questions.

CONS:
  • Customers have complained that the pressure of the system falls after the system has been in use for a few months
  • The system may leak after some time. However, tightening the fittings may solve this problem.

How We Tested

We took each reverse osmosis system through a series of tests to make sure it was really top-notch. We used professional grade testers to check whether the output of the systems was actually as healthy as said. For pH, we used the HM Digital PH-200 Waterproof Ph Meter, which is more accurate than ordinary pH papers.

The tester also allowed us to check water temperatures at varied PSI. For efficiency, we manually operated each system and compared the ratio of waste to pure water to be certain that the features checked out.

The last tests we carried out were the effectiveness tests. Since this is the important feature, we took out time to confirm and re-confirm the purification properties of each system. We used different TDS meters including the Waterproof Ec / Tds / Temp Combo Meter / Professional Tester – Com-100 and the TDS Meter Inline Tester to avoid the risk of malfunctioned testers.

We were able to establish that each system was extremely affective in purifying water by eliminating TDS creep, chlorine, fluoride and arsenic while maintain the appropriate pH and water temperature. Our tests concluded that the above systems are the best.

All Types of Reverse Systems

Reverse Osmosis (RO) systems are grouped differently according to their stages of filtration as well as their use, be it commercial or residential.

However, residential and commercial RO systems fall under the categories compiled below (over the counter and under the counter) so no need of getting into much detail with them. Check out below the types of RO systems:

  • Counter top RO systems

This type of RO system is generally small and like its name suggests, it is installed on the kitchen table next to the faucet.

Unlike other advanced RO systems, you don’t need to worry about installation costs with the counter top systems since you can install them by yourself. But since they are small and compact, they produce water in small quantities therefore making them ideal for small families.

  • Under the counter / under the sink RO systems

This type of RO system is much larger than the counter top RO model. Since under sink RO units are large, they produce the high amount of water making them suitable for large families and even for commercial exploits. When connected, clean, filtered water is produced directly from the water taps since the units are fitted under the sink where the water faucets lie.

Despite all its advantages, you will have to incur installation costs while maintenance is a bit more costly than counter top RO models.

  • RO systems with water tanks

RO systems with tanks are so convenient because they store filtered water which makes it accessible at any given time. But despite making filtered water readily available, it is common knowledge that stored water changes taste over time and may not be fit for drinking.

  • RO systems without water tanks

RO systems without tanks is a new technology that was introduced to solve the problem of stored water contamination. This unit features sieve membranes that filter water in the pipes in a matter of seconds and sends it directly to the faucet, therefore, curbing the need to store it.

Since the filtered water is produced instantaneously, this type of RO model is ideal for both commercial purposes and home use.

5 Stage Reverse Osmosis System

A 5 stage RO system is a type of multistage RO system with five layers of filtering to remove impurities in water. Each of the five filters in this RO model has its own unique function.

For example, the sediment filter is useful in flushing out debris such as dirt while the carbon filter is vital in removing chemical compounds that change the taste and odour of water. As for the 5 stage filter system, it features a filtration stage known as the remineralisation stage.

Since the fourth stage of filtration involves getting rid of all minerals from water; the remineralisation stage (fifth stage) is very important. This process involves adding nourishing minerals in the filtered water that is healthy for your body.

4 Stage Reverse Osmosis System

A 4 stage RO system has four steps of filtration. The difference between the 4 stage and 5 stage RO system is the remineralisation stage. But while both RO systems produce drink worthy water for human consumption, the 5 stage RO produces mineral rich water which is much healthier than the 4 stage RO system.

The first filtration process of the 4 stage RO system involves getting rid of debris and sediments from water.

The second filtration stage is known as carbon filtration and is important in removing chorine from water.

The third stage and most important stage is known as RO membrane stage. This stage is where the water is subjected to extreme pressure through the RO’s semi-permeable membrane to remove all impurities.

The last fourth and stage of the 4 stage RO system is the polishing stage where the water goes through another carbon filter to trap all the remaining chemical compounds. Since water can hold a large amount of chlorine, two carbon filters are fitted in this 4 stage RO to help share the burden on the filters to prolong their lifespan.

Whole House Reverse Osmosis System

Just like its name suggests, the whole house RO system is perfect for use in the entire house. Earlier, we mentioned some of the most ideal reverse osmosis systems for home which you can refer to above. The whole house RO system is also suitable for small commercial properties like restaurants, labs, green houses, clinics, coffee shops and café shops, etc.

Despite being small, compact and light weight, this type of RO system has the capability to produce as much as 1,500 gallons of water per day so its compact nature should not fool you into thinking that it is inadequate.

What’s the most interesting part?

In terms of build, whole house RO systems are usually made from heavy duty stainless steel rather than powder coated steel or aluminium for durability and to prevent rust from contaminating the filtered water.

The whole house RO system features an advanced purification system of sieve membranes that are perfect for purifying borehole and well water to remove the salty taste off it. This RO model can still be used to filter city-treated water to produce purified water at every tap.

GE Reverse Osmosis Filtration System GXRM10RBL

GE, a household name regarding electronics released this GXRM10RBL water filtration system a few years back and in doing so it raised many eyebrows among critics. This RO model from GE is a 3 stage filtration system that comes with a tank reservoir and is fitted under the sink to filter water coming through your home water faucets.

Since the GE is only a basic purification system, it can only manage to remove just 21 different contaminants from water as opposed to the 60 contaminants from other RO filtration models. While this fact might put off some people, it is worth noting that is merely a small fact because the GE has been approved by the Public Health and Safety Organization.

Below we look at some of its properties that make it special.

  • Design and Specifications

The GE comes with many useful accessories so it is extremely hard to give the exact shape and the exact materials used to construct it.

However, most components are made or stainless steel and plastic with the stainless steel components spotting a chrome finish while the plastic components have a white finish that makes it super easy to clean. At about only 21lbs, the GE is a lightweight RO system.

This unit’s overall dimensions measure 15 inches by 14 inches by 5 inches while the tank’s dimension measure 15 inches by 11 inches by 11 inches meaning it can hold approximately 2.05 gallons of water.

  • Features

The GE is well-equipped with features that improve its overall performance.  Some key features include:

  • 3 stage Reverse Osmosis filtration system that purifies water to make it safe for drinking.
  • Chrome faucet that comes with the full set of installation kit.
  • Impressive six-month filter life span or should be replaced after filtering 900 gallons of water.
  • Light indicator that alerts you when it is time to replace the filters.

  • GE’s Performance

As for the performance, the GE performs at an average level compared to similar priced RO systems on the market. In all honesty, nothing about the GE’s performance particularly stands out.

This under-the-sink filtration system uses the reverse osmosis process to filter water with its 3 stage filtration system. The GE is highly effective thanks to its adjustable water pressure range of 40PSI minimum pressure and 125PSI maximum pressure.

As for convenience, the GE’s tank reservoir can store as much as 2.05 gallons of readily available filtered water. Concerning the temperature and pH limits of the GE, it can produce water at temperatures between 40 – 100 degrees Fahrenheit and pH levels of between 4 and 10.

  • Cost

The GE is well priced. You get value for your money with this filtration system. After six months when you need to replace the filters, you will be glad to know that genuine GE replacement filters are readily available but are a little costly.

However, if you don’t mind off-brand filters, you can find them at much cheaper rates however they don’t guarantee you the same performance as genuine GE’s filters.

PROS:
  • Water tank
  • Decently priced
  • Produces high quality filtered water
  • Comes with all the vital accessories included in the package

CONS:
  • Fragile plastic build
  • Removes fewer contaminations than other models

Verdict

All things considered, the GE is worth consideration if you are in the market for a 3 stage RO system. While it doesn’t have a lot going for it, this 3 stage RO system is decently priced and notifies you when you require replacing the filters. This GE is ideal for small homes or large homes that don’t heavily rely on filtered water.

Osmosis System Filters

RO water filters are responsible for getting rid of contaminants in water to leave it clean for consumption. The filtration process involves using pressure to force water through a semi permeable membrane to filter out contaminants.

These RO filters flush out over 65 different contaminants at a 99 percent success rate. Most RO systems feature three or four filters.

Here they are:

  •  Sediment Filter – The sediment filter is the first line of defence against contaminated water. This pre-stage filter not only flushes out sediments like dirt and silt to purify water but also to protect the sensitive membranes from damage by the sediments.
  • Carbon Filter – The carbon filter is different to the sediment filter. It works by getting rid of chemical composites such as chlorine to improve the taste and odor of water. Leaving such chemical compounds in the RO system lead to the deterioration of the RO membrane.
  • Reverse Osmosis Membrane – As mentioned above, the RO is a semi-permeable component that only allows purified water through while flushing out 99 percent of contaminants that may have gotten through the first two system filters.
  • Polishing Filter – The polishing filter is basically an additional carbon filter fitted in the RO system to polish’ off or get rid of the remaining odor and taste in water. RO water systems with four filtration stages produce more refined water than three stage filtration systems.

How To Choose

So, after making a decision to drink healthy, sweet, odorless water and figuring out that an RO system is the best option to attain this, what is the next thing?

There are some factors that need to be put into perspective. Given that there are many RO systems selling at very affordable prices, the best way to distinguish between superior and inferior systems is checking the features. We have a list of features to look out for.

Are you ready to learn more?

Check out the following properties.

  • System Type

Check whether the system is a countertop or under sink type. Countertop systems are ideal for those who rent apartments since it requires little fixing. Under the sink, types are ideal for users with permanent homes.

We recommend under sink RO systems since they are only installed once and further maintenance is easy. Further, they do not require counter space in the kitchen. Ensure that the size is not too large.

  • The GPD

This is the acronym for gallons per day. When buying an RO system, check that its GPD is enough for all water needs. The higher the GPD, the better the system is. However, it would a waste of money to buy a system with high GPD for smaller households. Purchase the one that suits the household.

  • Installation

Some RO systems are quite difficult to install or have a high installation cost. Ensure that an instructional manual provides a well labelled diagram. In addition to this, there should videos online clearly showing how the system should be installed. We recommend that a good system is one installed in less than one hour.

  • Efficiency and Effectiveness

Ensure that the system cleans, purifies and sweetens water to the maximum. Also, check that it does not waste too much water.

  • Durability

Confirm from the manufacturer the life length and how long it takes before replacement of filters and the membrane. In our experience, an average system requires that filters be changed in six months and the membrane in a year. If there are systems that exceed this average, they are definitely better.

  • The Price

The RO system should have a price fair to the seller and the buyer. But as the rule of thumbs, when quality is of concern, price may be overlooked. We strongly advice against overpaying just because the manufacturer say the system is good.

Installation

Believe it or not, it is a simple, DIY activity. It is good to explore whether all the necessary fitting have been delivered. The parts may include a faucet, a storage tank, filters, shut-off valves, and tubing. After confirming they are there, we suggest the following steps be followed:

  1. Decide where exactly the components of the equipment are to be installed.
  2. Drill a hole through the sink where the faucet is stand. An electric drill may be needed for this activity. Depending on the material your sink is made of (metal or porcelain) choose the appropriate type of drill to perform this operation.
  3. Fit the faucet in the drilled hole. All parts above the rubber ring should be above the sink while the others fall on the under the sink. Tighten the nut below the sink.
  4. Choose an appropriate place where the storage tank is to be placed. Fix any tubing in line with kitchen cabinet boundaries to avoid clumsiness
  5. Install the shut-off valve. This valve links the supply line to the already fixed faucet, and the line should be shut off during installation. The valve requires no tool; it can be fixed by freely by hand.
  6.  Install the drain saddle valve, which later connects the system to the drain pipe. A small hole is to be drilled on the side of the drain pipe where the systems drain line meets the drain pipe. A clipping should be used to fix the two.
  7.  Connect the tubing at this point. Also, connect other components of the systems- filters, and membrane.

Stages of Filtration

Except for a few systems, reverse osmosis systems have five stages of filtration. Some systems go as far as incorporating two more stages and continue to give ultra- safe water for drinking. Other systems have small designs and use a four-stage filtration model.

What happens during the stages?

  •  The First Stage

Water from the cold water supply line is fed to the system through connected tubs. This water passes through and comes into contact with a sediment filter. At this stage, large particles such as sand particles, rust, dust, and mud are removed. This filter serves to protect the next filter from filling up and leaking as well as damage.

  • The Second Stage

Most RO systems place a GAC (Granular Activated Carbon) filter at this point. Its main function is to remove chlorine and fluorides. These pollutants can damage the membrane and impair its life span.

  •  The Third Stage

A CTO (Chlorine Taste Odour) filter is installed at this stage. As the name suggest, the filter removes chlorine, bad taste and odor from the water. Further, the cloudiness in contaminated water is removes at this stage.

  • The Fourth Stage

This is referred to as the reverse osmosis stage. A semi-permeable membrane (TFC or CTA) is installed to filter out dissolved VOC chemicals as well as other dissolved solids.

The membrane with pores measuring 0.0001 microns in diameter filters out bacteria and water viruses, which have slightly higher measurements (0.02-1 micron). Water from this stage is pumped to the storage tank. The waste water is taken down the drain pipe.

  • Fifth Stage

The water from the storage tank passes through coconut shell filter in this final stage. Here, odours and smells are removed to give fresh tasting water.

Reverse Osmosis Efficiency and Waste

Wondering what is the negative side of RO systems?

The answer is that they do waste water during purification. The efficiency of an RO system is summarized by a ratio of wasted water to pure water produced. Traditional systems retain about 15% of the water and waste the rest. Commercial systems retain about 80%. However, their RO membranes have larger pores and hence have a larger TDS.

Household RO systems can be modified to reduce the waste drastically. Our research shows that RO systems using an inbuilt permeate pump or featuring the Water Saving Smart Technology are very efficient with ratios of 1:1. We, therefore, recommend them more.

Warranty

Different manufacturers of RO systems offer different warranties on their products. It advised that the buyer be fully aware of the warranties granted to them. Our research shows that the most common granted for RO systems is one year, sometimes with a money back guarantee of one month.

We advise buyers to look out for this warranty when purchasing a system. Whole house system warranties may go to between five and ten years. However, beware that warranty laws change from state to state. Comply with the laws of your state to enjoy the full benefits of the warranty.

9.5 Total Score
Our Verdict & Recommendations

The road to getting clean, healthy and tasty water is a simple one. All that is needed is an RO system.

Sounds easy, doesn’t it?

Most reverse osmosis systems use JG fittings that are easy to install in the under sink with the help of an installation diagram to maintain zero installation cost. Within no time, fresh delicious water comes running through the faucet. We advise that the system have a pump so that efficiency is preserved. With enough pure water in the storage tank, unlimited water will be available for drinking, cooking and for the aquarium.

With our journey of the best reverse osmosis system for home coming to an end, we recommend the iSpring RCC7 WQA Gold Seal Certified 5-Stage Reverse Osmosis Drinking Water Filter System as the rating proves to be #1 Amazon bestseller. After all, it is Gold Seal Certified by Water Quality Association and has 1-year money-back guarantee along with lifetime support from iSpring.
