i shopuld just point out here that if you drank nothing but "pure" water, which people keep drivelling on about, you would die pretty quickly. There realy isnt muchh difference between dasani and tap water because the "minerals" they put in will be pretty similar to the minerals they took out when they ro'd it. And Im sorry but treating it with ozone seems a little excessive? why are they doing this, exactly? After all that filtration there would be nothing to kill, so the introduction of a corrosive, poisonous gas seems a tad ott.
