Sorry, but to each his/her own. Tap water is chlorinated AND fluoridated! And the pipes that the water travels down have their own set of problems, as does the source of the water to begin with. If I can taste my tap water, even after it's passed through a filter, then I'll choose Nestle's purified water. They receive consistently good marks and it tastes good. If tap water makes my coffee taste bad, something is wrong.View Thread
