Abstract
A filter assembly for a water purifying apparatus including a plurality of cartridges. Each cartridge includes first and second ends and an interior volume containing a filtering medium. A plurality of end caps are respectively connected with the first ends of the plurality of cartridges and each end cap includes a water inlet and a water outlet. A removable manifold is coupled with the water inlets and water outlets and the manifold includes a pair of auxiliary ports. One auxiliary port directs water from the cartridge assembly to an auxiliary processing device and another auxiliary port directs the water from the auxiliary processing device back to the filter assembly. The water inlets and water outlets extend generally parallel to a longitudinal axis of each cartridge. The cartridge includes an outer tubular member in fluid communication with the water inlet and an inner tubular member in fluid communication with the water outlet. The inner tubular member has a first end connected in a sliding manner to the first end cap and a second end rigidly affixed to the second end cap.
