  1. Lise

    Tastes good to me. One of these days I may get a water tester. Otherwise can’t say one way or the other if it comes out pure or not.

  2. David Bailey

    Not only was this supper easy to install in my apartment, but now I can drink my water. The city that I live in has really bad tasting water and this has solved my problem.

  3. Joan R

    We live in a small city in DE. When you run the water into a cup you can immediately smell the chloring/bleachy smell. When you make hot/cold tea or coffee it came out bad. Drinking the water gave indigestion. HOWEVER, after I hooked this up to the kitchen cold water, ran the water for 15 minutes, then poured a cup to drink, what a godsend. The nasty smells and flavor is gone, not taste to the water as should be, no indigestion from drinking the water, and the coffee and teas we make are spot on. I will use this product forever.
