Abstract: An improvement in a water filter cartridge of the type having a substantially frustoconical vessel member defining a vertical axis and containing a granular purifying agent which is insoluble in water. The vessel member has a screen-like end wall portion at the lower end thereof. A hollow substantially frustoconical cover member is attached to the vessel member and coaxial with the vertical axis thereof. The cover member defines an annular rim portion and a first slanted portion extending upwardly and inwardly from the rim portion, and a substantially flat-topped second portion, the first portion having a multiplicity of vertically oriented water entry flow slots arrayed therearound. The vessel member and the cover member together define a container for receiving and retaining said granular purifying agent therein. A first layer of filtration material is disposed within said vessel member and layered upon said granular purifying agent. The water filter cartridge is for use in a water filtration device.

Abstract: The invention relates to a replaceable filter cartridge for a use in a water filtration device. The cartridge has a substantially frustoconical vessel member defining a vertical axis with the vessel member having a screen-like end wall portion at the lower end thereof, which end wall portion permits water to flow therethrough. A hollow substantially frustoconical cover member is attached to the vessel member in coaxial alignment with the vertical axis. The cover member has a multiplicity of vertically oriented water entry flow slots. A non-planar compressible first mass of filtration material is frictionally retained within said cover member and a non-planar compressible second mass of filtration material is positioned within said vessel member in juxtaposed relation to said end-wall member. A granular purifying agent, which is insoluble in water, is contained within said vessel member, and layered upon the second mass of filtration material.
