Review: very robust yet economical system for your drinking water purification needs. - Ive purchased this unit multiple times 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 permillion) 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. That's why bottled water is so popular, but its labor intensice to buy cases of water and carrythem home 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. Aftee you start drinking clean clear water for about 2 weeks you taste will start to come back and if you 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 doesnt leak, tastes great and new filters clear the water down to 2-7 ppm. Even after several years amd hunddeds of gallons of water filtered without chamgingnthe filters 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 docume ted and this is a very robust yet economical system for your drinking water purification needs.
Review: Crystal-Clear Water with Easy Setup - I installed the FS-TFC 5-Stage Reverse Osmosis System under my kitchen sink, and the results have been outstanding. The water tastes noticeably better — no chlorine smell, no metallic aftertaste — just clean, refreshing water perfect for drinking, cooking, and even brewing coffee. Setup was surprisingly simple. The instructions were clear, and I didn’t need professional help. The compact design fits easily under the sink, and the 100GPD fast flow rate means I never run out of filtered water. I also appreciate the extra set of filters included — a thoughtful touch that saves money down the line. The system removes up to 99% of contaminants, including fluoride, lead, arsenic, and heavy metals. The wastewater ratio is about 3:1, which is standard for RO systems, and the filters last 6–12 months depending on usage. If you’re looking for a reliable, affordable reverse osmosis system that doesn’t take up much space and delivers excellent water quality, this one’s a winner.

## Questions & Answers

**Q: Installed all new filters. no water flowing from ro filter clean side. continuous flow to drain. was working good for 6 months. what is the cause?**
A: Hi Chris , you may have to change the filter. I had the same problem here because of a lot of calcification ,poor water quality so to prevent  short filter life I install a pre filter before the reverse osmosis unit.  hope that be of help to you.

**Q: Does this unit come with a auto shut off valve?**
A: No! The main input line does not have a high-flow auto shutoff. The line is controlled by a manual shutoff from the pre-existing cold water line.

**Q: Where can i find the replacement filter ?**
A: If not Amazon, try Home Depot. That is where we found our original filter. This Amazon one was a replacement for that one, which cost the same as the original, but came with a set of replacement filters! Same price, for a far better deal.

**Q: Can this be switched between treated and untreated? I only need drinking and cooking water to be treated.**
A: No.   This is a separate (included) faucet that provides the filtered water.   Your normal sink faucet will continue to work as it is now.

### ⭐⭐⭐⭐⭐ Great Reverse Osmosis
*by R***N on October 22, 2021*

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.
