We have been using this Zero Water Pitcher for 3 years now.  As a household of only 3 we go through water like crazy.  Having switched from a different brand to this brand has us consuming more water than we ever did.  That is because it truly does filter the water to reduce/eliminate contaminents.  When guests come over, they always ask for water because our water is better than theirs to which we state to make the decision and purchase this brand.
