Any readily available in-line cartrige filter will suffice. I use a two filter setup, one for sediment, the second for "taste" , which filters out chemicals and chlorine using activated charcoal. This takes care of my entire household, and was installeg in my basement. You can install them under a sink, or anywhere you need in the water line. A faucet filter works too, they run a little slow, but are very convenient, and can be switched off for regular water use if not needed.
