I don't know how people can drink tap water. Maybe it's just the tap water here in pawtucket that is worse than others, but I've been over people's houses where they swear the tap water they get is good, I've tried it, and it tastes terrible. We have an Inglis water filter built into our refrigerator, the water that comes out of that tastes phenomenally better than the water that comes directly out of the tap, no lasting chlorine flavor or anything like that. I sometimes forget I'm even drinking water it's so good. I could never go without buying a filter for the water in my house, I don't care how supposedly "clean" the water from the tap is.
