I'd rather drink tap water, it has less contaminants and lower
bacterial load than bottled water.

The only reason for a "filter" on the mains water in this country
would be if it's very hard or if you have a private supply from a
spring or well. In which case you may well still be better off with
UV treatment to kill the bugs rather than a filter.

Maybe it is worth reminding this "scientific (of sorts)" daughter
that the human animal has a very effective immune system and that the
vast majority of the planets human population does not have a
purified and clean water supply. You don't, *generally*, see the
human population being ill or dying from water bourne disease.

or even water borne ones. ;-)
