Well, not to go into all the various paths replies have taken, but a
lot of cartridge water filters include a bit of heavyish metal (more
typically silver than nickel because it's less toxic to people) because
it keeps bacteria down, which otherwise could be a problem growing
inside the filter between replacements. As a couple of guys have
mentioned, reverse osmosis doesn't have this problem and produces
exteremely pure water; the other option, of course, is a still (look in
laboratory supplies places) but that's not very adaptable to a faucet
type situation, and sometimes doesn't give you as much purity as a
filter does, depending on what's in the water in the first place.
