Have seen a few comments about US water quality. It may be good in general, but the water here in Los Angeles is horrible (though sterile?). I grew up in Ventura County and never thought twice about tap water (and laughed at others too) until I moved here.<p>Part of it is LA's fault, they use so much chlorine it smells like you're drinking from a jacuzzi. Even after letting it sit for a day or two for the chlorine/ozone to dissipate, it still tastes bad in a similar way. I'm not sure what the other minerals/contaminants are. Finally, our current building is old and we get red rusty water first thing in the morning once a week or so.<p>So yes, we filter our water before drinking, pretentious or not. We have a PUR 3-stage attached to the sink, and it costs a bit more than I'd like, but honestly ~10 bucks a month is nothing compared to the night/day improvement we get from it. I hope the claims about removing heavy metals are true for my daughter's sake.
