    very good quality, am pretty happy with my purchase

  2. RK

    I had the FS10 installed under my kitchen sink with a separate faucet 18 months ago and I am very happy with its performance. We use it for all our drinking need, including tea, coffee, shakes, etc., as well as for washing veggies. The filter is still going strong! The filtered water’s taste hasn’t changed and it’s flow rate hasn’t slowed down that I can tell.
    Thanks, ProOne!

    We received the FS10 system about 3 weeks ago now. My husband was able to install it easily (& he is not the handy one!), and we’ve been enjoying clean water ever since! The replacement filter cost ends up being much more affordable than any other option I found (filtered water bottles, pitchers, etc) and I’m very happy with our decision.

    Great product great fresh tasting water. I got tired of refilling gravity fed systems. This easy to install Filter solved all my problems. I highly recommend this product to people all the time
