3-Stage Under-the-Sink Filter System works great!

My husband installed the system without any trouble and also put in a separate faucet for it, so it is very convenient. The water coming out tastes great! We are very happy with the product and quality of water we are getting.

I love my Clearly Filtered pitcher but, I love the 3 Stage Filter even more. It is so convenient I bought two, having houses in California and Tennessee.

I like it

It’s healthier than bottled water which is what I was using before. With the recent bottles water arsenic contamination news, I feel even better. I wish there was a way to see how much contaminants are filtered at the end of the filter cycle.

Very Happy w my Undersink Filter

Very easy to install. When I pour filtered water into a clear glass I can see a very obvious difference. I can taste the difference. I’m very happy I don’t need a second faucet on my kitchen sink for the filtered water.

Under Sink Filter

Bought this system a couple of years ago. Love it! Easy install, limited maintenance- filter changes only and best of all I drink safe clean water right out of my kitchen sink! Also installed shower filters and own a couple of pitches for travel.
