I agree with Siobhan's recommendations re: the best water filtration
devices.  I see a lot of places advertising RO and distillation as the best
because it is the most 'pure'.  But being so pure, it lacks the minerals
that are essential for health....When I was working in a lab in grad school,
a friend of mine told me he knew a guy who decided to drink nothing but
de-ionized water - that's just about the 'purest' water you can get, devoid
of anything but the H2O molecule, used in experimental work because it will
not contaminate your samples with other minerals or metals.  Apparently
after some time, he got ill, and had to be treated for his electrolyte
imbalance.  OK, maybe it's some kind of lab-geek's urban myth, but i think
there's at least a grain of truth in it.  And I don't know about y'all, but
distilled and RO water tastes pretty flat.  Ideally, i'd prefer to drink
fresh spring/river water (chock full of minerals, BTW), but that's not
possible in downtown Toronto.  RIght now I'm saving up for a good quality
combined carbon-zeolite type of filter.
