We have been using zero water filters for the past 10 years before that our tapwater was extremely great tasting The tapwater came from a very large reservoir in Scituate Rhode Island But year after year there was more chlorine added to the water There was so much chlorine It was disgusting Then we switched to zero water filters and have been drinking the best filtered water available anywhere We told all of our friends and relatives about zero water And virtually all of them have been using zero water for quite a while We get so many thank you cards and phone calls for recommending Zero Water filters My wife and I want to thank Zeeo Water filters for 10+ years for the best tasting water anywhere
