ABSTRACT:
A filter cartridge has an inner filter element and an outer filter element concentric therewith. The filter elements define a water flow space between them and a container of sanitizing granules is positioned in the space. The granules kill waterborne bacteria that come into contact therewith. In a more specific embodiment, the container is in a riser tube positioned in the water flow space. In another embodiment, the cartridge includes two riser tubes, each holding a container of sanitizing granules. In the alternative, one riser tube holds a container of an oxidizer such as chlorine or bromine pellets.
