WATER FILTER CARTRIDGE A self-contained, disposable water filter cartridge for a water treatment system for treatment of potable water has one-way ball check valves at the water inlet and water outlet to the cartridge. The generally cylindrical water filter cartridge is generally spherical on one end while substantially planar on the other end and is of a welded plastic construction. Asymmetrical lugs radially disposed about the periphery of the planar end are adapted to mate with an apertured deck of a water treatment system.
