I bought this dispenser because I drink a lot of water and the water coming to my house tastes terrible.  This filter removes all the pollutants that make my water taste bad.  It also make coffee taste 10 times better.  I am a coffee snob who drinks nothing but KONA Coffee.  When you are paying up to $40.00 a pound I want great coffee not coffee polluted by bad tasting minerals in my water. I would suggest this dispenser to anyone and I have told a number of friends who have gone out and purchased one.  I travel with it all the time and take to my condo fill it up and let it "Zero-Out" my water so it tastes great.  If you are thinking about getting a good filter, forget anything except ZERO-WATER!!
