“Hi Aquathin,

I’m not sure where to start.  We had our Aqualite installed in 2008 when we were renovating our kitchen. Someone had recommended it to us and it sounded like a good idea not that we had any experience with this before. I cannot imagine my life daily without it!

We have a separate line run down in the basement where the cats have their food and water and they have the pure water in their bowl every day.  We use it for coffee, iced tea, and for everything we cook with. Also, we have it run to our refrigerator instead of just the regular tap water, our ice is made with Aquathin water.

My kids call me a water and ice snob because when I go out, I don’t like the taste of other waters and even what the ice does to restaurant drinks.

Thanks from a very satisfied customer.   Bev & Emmett”
