  1. John (verified owner)

    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

    We love our FS10 water filter. I installed it myself under the kitchen sink. We wanted a water filter to reduce the cost and waste of using so many throw away plastic bottles. I just received my FS10 replacement filter that I ordered. We don’t need the replacement yet, just thought it would be handy to have a backup ready to go.

    I’ve been using the FS10 filter system at my cottage (in central Ontario, Canada), drawing lake water, for a few years now. It is a seasonal property so we are only there off and on between May and October. I use it with a dedicated faucet for drinking water and change the filter every 2 years. I haven’t had the water tested but I think the water quality has been exceptional. I can’t detect any odours or taste. Very clean and clear. A contractor I had out last year working on our roof said he’s tried drinking water running through different systems at various locations (on lakes) in the area over many years but had never tasted water this good. This has saved me a bundle from having to buy bottled water (and the large plastic bottles!) and the hassle of hauling over by boat. Best investment I’ve made at the cottage.
