Abstract
A water filter system includes a water filter assembly and an enclosure. The water filter assembly has a housing with a water inlet and a water outlet, a filter portion within the housing, and a reservoir portion within the housing apart from the filter portion. A window in the housing conveys ultraviolet light into the reservoir from an external light source. A water channel conveys water from the inlet to the outlet through the filter and the reservoir portions. The enclosure removably receives the water filter assembly in a cavity within the enclosure. An enclosure water inlet mates with the filter water inlet, and an enclosure water outlet mates with the filter water outlet. A light source within the enclosure is arranged to direct light into the reservoir portion.
