Does filtering water before drinking it actually do anything to it? According to the water quality reports, tap water in the US is safe to drink, so I am wondering if the filter serves as mainly a psychological thing. Can anyone point to any studies on this? Yeah, I know how the charcoal in the filter is supposed to work. I was just wondering if there are really any impurities to begin with.
