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. A split support ring, having a series of upwardly, radially inwardly slanted projections is positioned within the cover member, in supported relation upon the rim portion of the cover member to contain the non-planar compressible first mass of filtration material in compressed relation within the cover member.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.] In a water filter cartridge of the type having a substantially frustoconical vessel member defining a vertical axis, said vessel member having a screen-like end wall portion at the lower end thereof, which end wall portion permits water to flow therethrough and a hollow substantially frustoconical cover member attached to said vessel member and coaxial with the vertical axis thereof, said cover member defining an annular rim portion and a first slanted portion extending upwardly and inwardly from said rim portion, and a substantially flat-topped second portion, said first portion having a multiplicity of vertically oriented water entry flow slots arrayed therearound for use in a water filtration device, wherein the improvement comprises:a non-planar compressible first mass of filtration material frictionally retained within said cover member;a non-planar compressible second mass of filtration material positioned within said vessel member in juxtaposed relation to said end wall portion;said first and second non-planar masses of filtration material each being constructed from a multiplicity of fine flexible fibres of a substance which is insoluble in water;a granular purifying agent, which is insoluble in water, contained within said vessel member, and layered upon said second mass of filtration material; and,a split support ring, having a series of upwardly, radially inwardly slanted projections, said split support ring being positioned within the cover member, in supported relation upon said rim portion of said cover member;wherein, the non-planar compressible first mass of filtration material is held in compressed relation within said cover member by said split support ring.
