Abstract: A water filtering and purifying apparatus made according to the present invention comprises a water filtering and purifying apparatus for filtering and purifying water as it is ejected from a container at low gauge pressures generated by manually squeezing the container. The water filtering apparatus includes a cover for attaching to the container wherein the cover has a pressure responsive venting system for allowing air into the container while substantially preventing air and water contained in the container from escaping. A water filtration and purifying system is contained within the container and the filtration and purifying system comprises a replaceable pleated filter connected to a purifying cartridge.

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.
