5-Stage Reverse Osmosis Water Filter System, NSF Certified 100GPD RO Water Purifier Under Sink Reduces 99.999% Impurities, with 4 Extra Replacement Filters Free for Home Drinking

I have only been using this for a week now, but the performance of this system is good. The water tank had the correct air pressure and the only leak I had was at the water tank fitting. The instructions recommend 6 or 7 wraps of the enclosed teflon tape, which I had initially put only 3. After 3 additional wraps that took care of it. I measured the drain water for the first few quarts of drinking water produced, I measured 4 quarts of drain water for 3 quarts of drinking water. I have city water, so the pressure I am guessing is in the 60 to 70 psi range. I measured around a gallon of drinking water produced per hour. Installation was easy, plenty of 1/4" tubing was included in the kit. Worst part of the install was removing a very tight hand soap dispenser! Water taste is as expected for a 5 stage system (no 6th stage to add minerals back in). Extra filters included are a nice plus (no extra RO membrane of course) so no filters are needed for the first year. The instruction book is in color and big enough to read without a magnifier. I favored this unit due to the slightly smaller size. Tank is 3.2 gallons

I was a bit skeptical of how this was going to work or even if it would. I am a commercial appliance installer and find my way around with pretty much everything and believe that patience is important on this installation. I wanted a machine that had enough water flow to not cause my Leveluk K8 machine to get the low water volume error and thought it was a bit of a gamble on achieving this. My RV sits currently at a site which has substantial water pressure which ranges from 75 to 90 pounds. At first I had an issue with getting the tank to fill but learned there was air trapped in the RO cylinder. This problem was resolved by leaning the assembly of filter to the right and to the left and you will here the air purge if such instance occurs. I have not tried using this with the 45 psi RV pump but will do so at some point. I believe that removing some air from an emptied tank down to 5psi would still allow filling tank. That would probably then take it much longer than the 45 minutes which it currently is taking to fill. I am currently able to fill the tank empty of water with an air pressure of 8 psi which gives great water flow once full of water. I also filled it with only 5 psi and was still able to achieve enough water flow to run the k8. There certainly is no issue with water flow volume and is more than plentiful to run water to gather nearly a gallon of kangen water but no more than. This is perfect IMO. The instructions says to drill a hole 1/2 inch for the faucet which is definitely much larger than needs to be. I went much smaller just to satisfy my OCD and the event that I wish to remove and plug hole at some time in the future. I doubt that will be the case though. I used a bit size 7/8 for the faucet and it was a perfect hole size. It has taken about 4 full tanks being flushed before the odd taste is removed. I also read that the drain water keeps running on some reviews though I am not having such an issue as I have been checking it often to the point that I am now confident that it is working with zero issues. Well done with an excellent price.

We purchased this to replace a failed system installed by the builder. This unit is more efficient and easy to install. Would highly recommend to family and friends.

I purchased this system for our family of 3, plus pets and plants. I installed it under the kitchen sink along with a couple of other components, but I quickly learned a few things to help others with if its your first time or if it's been a while. I broke it apart into sections so skip to what you need or read all three. It's not too overly verbose :) The sections are - this product kit itself, the installation of the system, and optional components that will improve your system's efficiency, meaning you waste less water through the filtration process itself. 10 second version on how RO works: High pressure water is prefiltered and then pushed into an RO membrane - which is the reverse osmosis filter, with a pore size of approximately 0.0001 micron. That's nerd talk for super filter. After an additional filter, it can go right to the spigot for drinking, or you can run it through a mineralizer first - that's what gives it that nice, mountain spring water like taste. Notes on the RO Kit (Reverse Osmosis): Great price for the components, extra filters is great. The TANK - please DO NOT adjust the pressure by pushing in on the bike tire looking relief valve at the bottom of the tank. It's pre-set to the right pressure from their factory. It uses a bladder to help pressurize your water in the tank to deliver it more quickly to the spigot. --There is a connector piece with blue release tabs - the rest of the normal connectors are white. The blue one is your ONE WAY CHECK VALVE, and should be installed correctly already. I moved the position of mine when replumbing to be on the outlet side of the 5th filter. --The filter 'brackets' for mounting them are pretty flimsy, consider mounting or zip-tie into place. --- This Kit does create a lot of condensation on the bottom three filters, enough so that I had to make a drain trough. --- There IS an automatic shut-off valve pre-installed onto the mounting panel. It's the white valve with 4 lines coming out of it. This NEEDS your tank setup properly to work, as it uses the tank pressure to know when to shutoff water to the system. INSTALLATION: PERMEATE PUMP - this is the miracle worker, it uses a clever diaphragm system to increase the water output of the system and does so by using the discharge waste water pressure. This makes them at least a 1:1 efficiency or better. Without it, it produces 1:3 (water to waste ratio). I added a remineralization filter to mine then out to the spigot. I also added a 3-way splitter to a shut-off valve for my ice-maker line, which I installed on the outlet of the mineralizer right before the spigot. WITH A PERMEATE PUMP, ON 85psi INCOMING WATER PRESSURE, IT PRODUCES A LITER OF WATER IN 3 MINUTES. That's 125 gallons per day, a 25% improvement in water production with a decrease of 250 gallons of waste water, per day. Obviously you'd have to run it 24/7 for that, but you get the idea. CONSIDER ADDING: a permeate pump, a psi gauge on the incoming side of the water in your RO system, a remineralization filter (put it inline after your last filter), an additional water shut off valve, and a mounting panel to attach all the components to before putting the mounting panel in its under-sink position. Last thing - make sure to leave room under your sink for your water tank. EDIT: 4 months later, works great and we love it. The cats love the water in their fountain, and we enjoy not carrying 5-gallon jugs of water in from the car every weekend. :)

We installed this system, and the feed connector broke so I bought an APEC System ( only cuz it was the only system that arrive in a few hours ) and I was able to replace the feed connector from the APEC system and that worked with the FS-TFC system and I continued to use the rest of the FS-TFC parts until we started to draw water from the new faucet. At this point, the second thing that didn't work was the connector that was applied to the water tank. We couldn't get it to stop leaking so I grabbed the connector from the APEC system, and it immediately stopped leaking. After we uses the FS-TFC filters for a while, I'll just swap out the filter pack from the APEC system so that I don't lose the money that I spent on the FS-TFC. ( get some use out of it at least ) I'm happy that the parts were interchangeable and I'll try the iSpring system next. I'm not sure which one is the best and I only ordered the APEC because it would arrive the same day and I wanted to finish installing the RO system and this was my first time to install the system. Clearly, other systems use more quality parts and cause less of a headache.

I was apprehensive due to the price. This unit was packaged very well. The main unit came pre-assembled, meaning you do not have to connect the different filters together. The unit cam with tubing, and enough extra parts to suit many configurations. I purchased this to connect to my refrigerator water/ice dispenser. Because I had a steel braided hose for this, I needed to purchase a compression to push connect fitting from Lowes for my supply side. I then had to order a compression fitting for the hose output to the refrigerator line, and the compression fittings for plastic lines. all of these were less than 10 dollars, but, took a while searching, and Help from AI to identify the right fittings, but, they worked. No leaks upon assembly. I have had it installed for 2 weeks and still no leaks. I do have a leak detector under my sinks and toilets to alert me if there is a leak under or around them. I also ordered a Permeate filter because I wanted to cut down on the amount of waste water and have reliable pressure for the ice maker and the water dispenser on the fridge. The unit is smaller than a typical RO Filter so it fits great under my sink and allows storage for my cleaners. My ice is now free of all the floaters. The water looks great. The directions were great. AI Was able to answer my questions and concerns if I had any.

Ive purchased this unit multiple times now for each home I have purchased or worked on. When I test unfiltered tap water using a pen sized TDS ppm sensor (Total Dissolved Solids parts per million) City water is anywhere from 70-150 or more and typically tastes strongly like chlorine or fluoride or even sulpher and in the Vegas area it even came out brown. Perhaps that's why bottled water is so popular. But buying cases of water is labor intensive and carry to home, store until use then have to dispose of the plastic after. Using this filter setup the TDS reading taken in multiple areas never exceeded TEN (10 ppm) and has zero taste. After you start drinking clean clear water for about 2 weeks your sense of taste will start to come back. Then if you try to go back to regular tap water you will notice just how horrible the chlorine and sulfur tasting city water really is. After installing either 4 or 6 water filter systems of this exact model over the last 8 years I can confirm it doesn't leak, tastes great and new filters clear and clean your water down to 2-7 ppm. Even after several years and hundreds of gallons of water filtered (without chamging the filters at 6 month intervals as recommended) the water still tests about a max of 10-15 ppm and has no odors or bad taste. RO water like this is even cleared for use in CPAP machines that recommend distilled water use on the humidifiers. Several years of RO water in my Phillips Dream Station has had zero negative effects. The health benefits of clean water are clearly documented. This is a very robust yet economical system for your drinking water purification needs.

We purchased this unit, wondering if it was going to give us better water. We have a well and a water softener and my wife didn't love the taste of the water and I didn't like to use the water softener for working with plants. Our configuration was to just run the RO to the refrigerator so we didn't use the faucet. The start of this story was not super, but after the outstanding customer support I was able to install and had great tasting water. It did the job we were looking for it to do. 5 start rating for unit and customer service. More details: What I loved about this unit is that it had literally everything I needed to put it in. I have to say, this is the first time I've used the quick connect and it was intimidating and worrisome. But after using it and learning that you just have to push the outside ring inwards to get the pipe out and the little blue c rings keep that ring out, thus not allowing the plastic pipe to come out unwanted, I was relived. And they are so easy to work with, it is almost embarrasingly easy! The seller ships the unit with a pretty much plug and play manner, but also includes extras like water line, multiple quick connect adapters, the valve you can use and the sink faucet. Even Teflon tape. As with most instructions, reading them made the installation easier. Even the diagram on the instructions to take off the pipe would have saved me watching youtube videos on the topic. To install, you basically have to connect 4 lines to/from the unit. IN, OUT, DRAIN and TANK. I installed it in phases by connecting a 1/4" plastic pipe to the quick connect, into a 1gal water container. * starting at the line going into the pressure regulator - making sure water was coming from the line * out of the regulator * out of the unit * final configuration before connecting it to my refrigerator Bottom line is this worked great and I am very pleased. One thing to remember with the RO systems. The water goes through a bunch of filtration and then goes through a membrane, and the pressure is controlled by a pressure valve. Therefore, if you run the water directly through the RO, the water doesn't run fast. it took about 7 minutes to fill 12 cups of water when I first connected it up. About 30 minutes later, the 12 cups took less than a minute....more... Once the system is in its final state and if you leave it be for 15 minutes or so, the water comes out of the faucet (in my case refrigerator) like you'd expect. This is caused by that water tank that comes with the unit.

I got tired of drinking bottled spring water which I doubted the source! So, I invested in one of these filters knowing that it has been filtered in my very own home. The water comes out fresh, crisp and clean! I did the 6-month filter change and let me tell you the number of substances that are filtered is amazing! In the first picture you can see the new filter compared to the old filter. I poured the water into the cup to get a better look at it. By the time the water goes through the remaining 4 stages and reaches the tap, the water is crystal clear and fresh. I highly recommend it if you are looking to improve your water quality and remove harmful contaminants.

I had a problem with one of the plumbing fittings not being compatible with our thread fittings initially. The company was very prompt & good with their response . I purchased the fitting that would work for us & they reimbursed me for all the costs I incurred . I would highly recommend this company to all. I needed the RO unit as we have very hard water & need to reduce the mineral content for our humidifier. Works like magic! VERY HAPPY
