I’m going into my 3rd year using an AquaLiv water filter and must say I love it. I used to use an alkaline filter but when I moved, the faucets in my house could not adapt to that filter, and was very difficult to find a replacement faucet that would work without altering my counter top, etc. I already had a built-in filter setup so I researched filters and decided to try AquaLiv. I’m not disappointed! Filters are easy to change too!
