Abstract

A filter cartridge (100) comprises a filter media chamber (170), first (180) and second (185) conduits and ion-exchange filter media (190) disposed within the filter media chamber. The filter media chamber has a longitudinal axis (175), a closed end (120), a sidewall, and a connective end (140) opposite the closed end. The connective end comprises and inlet port (150) and an outlet port (160). The first conduit is in fluid communication with the outlet port and the filter media chamber. The second conduit (185) is in fluid communication with the inlet port (150) and the filter media chamber (170). A portion of the second conduit (185) is disposed adjacent to the ion-exchange filter media (190), and it has a terminus proximate the closed (120). Openings (155) in the second conduit (185) are disposed at a plurality of depths within the filter media chamber, and some of the second conduit (185) is disposed between the sidewall (130) and the longitudinal axis (175). The second conduit (185) may comprise hollow branches (186, 187) in fluid communication with a hollow core member (157) or may have a portion in the shape of a coil (5891).
