<p>The invention relates to a replaceable filter cartridge for a use in 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.</p> |
