ABSTRACT:
A water filter has an elongated base with an inlet opening near one end thereof to which is secured an adaptor ring for attachment to a water faucet. A first outlet opening on the base dispenses unfiltered water and there is a channel defined within the base that leads toward the other end, with an externally-operable valve being included for selecting between unfiltered flow to that outlet and flow down the channel. Located near the other end of the base is a mounting on which sits a water filter cartridge that communicates with the channel, and the cartridge delivers filtered water to a second outlet. A number of features include a color indicator to exhibit degree of cartridge usage, a reversible adaptor ring to accommodate different faucets and there are different aerator structures. Of particular note is the replaceable cartridge which includes a deflector for obtaining better usage of the main filtering material, an exteriorally-mounted first filter and an internally-mounted second filter.
