Contrary to belief, tap water nowadays is safe enough and clean to drink. What you smell and taste are trace minerals in pipes. Come on, its not going to kill you but the stigma is damning. The BottomsUp concept is a portable water purifier. You fill any PET type bottle with water, screw on the top and like Brita (or Pur), what comes out is a whole lot better tasting.
