    Great alternative to osmosis and a easy install!

  2. Eddie (verified owner)

    Had this filter for over 6 months and love it. Easy to install ! Recommend!

    I had a segue IV great filter I use there back pack version when camping, but the FS10 is better. water flow is better the water taste great( we have good water but is has has touch of chlorine ) I like its capacity my old system didn’t quite last a full year till the water started smelling a little pond like. It took about two days for it to stop looking like milk when you first pored a glass but now its clear.

  4. Jeff (verified owner)

    New user roughly a month now. Filter had slow drip on the intake brass fitting once installed and the Pro tech that called me back advised to remove the brass fitting and redo the teflon tape. It took a few attempts to get the quantity of teflon thickness just right but the slow drip stopped and has worked fine since. Milky water look went away in a day or so and clean ever since and tastes great.

    had to buy extra hardware to work with my setup, was easy to install. great water taste, better than my wirlpool fridge ice maker and water dispenser, recommend!

  6. Brian Beebe (verified owner)

    Easy install. Purchased a few things from the hardware store but was not difficult or costly. The water is very tasty. Milky (many tiny bubbles in the system) the first day or two, but then runs clear with no further issues.

  7. John Falkner (verified owner)

    My first impression of unboxing was this thing is large, not a bad thing, just understand the size. The install was very easy, and after several minutes of running the bubbles out, the water was clear. The water is very clean tasting. Buy!

    I received my FS10 filter about 2 weeks ago. I am pleased with this filter. There were no surprises after reading the reviews. I did have to go to the hardware store, that had been mentioned in the reviews, for bolts, washers and a 20”water supply line extension. They did include a 30” water supply line but I wanted it closer to the front of my cabinet for easier access. I definitely like the taste. As a test for my wife, I mixed store bottled water in the fridge with the filtered water in the same bottles. She couldn’t tell other than the seal being broke on the store bottles. Happy wife, HAPPY life!
