Abstract
Abstract A water filter apparatus includes a housing having a horizontally-disposed base unit. A coupling upstands from one end portion of the base unit and is attachable to a faucet for receiving a supply of water. An outlet is downwardly directed from the base unit to discharge water received through the coupling. Also disposed within the base unit is a valve that selectively permits the flow of water through the coupling and in discharge from the outlet. Upstanding from another portion of the base unit is an inverted cup-shaped cap. An input fluid channel within the base unit leads from the valve to the chamber defined by the cap, and the valve selectively permits the flow of water through the coupling into the input channel and from that into the chamber. A filter cartridge disposed within the cap has an inlet opening communicating water from the input channel to the filter material. The cartridge also has an outlet opening disposed beneath the top wall of the cap for communicating water from the material and out of the cartridge. Located at the top of the cap is a spigot for emitting water discharged from the outlet opening of the cartridge. Finally, there is a control for regulating the flow of water from the outlet opening of the cartridge through the spigot and another control for regulating flow rate.
