ABSTRACT:
A water filter cartridge for use in a water filtration system comprises a generally cylindrical ceramic pre-filter having a chamber containing a purification resin. An exit cap having a porous disc therein is attached at a first end of the pre-filter. Water to be filtered passes radially through the pre-filter into the chamber. The water then passes through the purification resin and the porous disc and exits the water filter cartridge through an opening in the exit cap. The ceramic pre-filter can be cleaned when it begins to lose its effectiveness, enabling it to be reused.
