Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 317 words
A filter device for filtering tap water to remove odors and impurities therefrom comprising: a. a top member and a bottom member comprising a lower discharge passageway adapted to be detachable connected together to form a Casing for an enclosed space adapted to contain a plurality of filter elements; b. said top member comprising a central passageway in an upper inlet connecting member adapted to be fitted to a faucet and the like, a valve member disposed transversely within said connecting member disposed between said central passageway and first and second parallel lower passageways, said valve member comprising two holes disposed 90* to each other and each adapted to be aligned with one of said parallel lower passageways when said valve is turned; c. a chamber disposed below said parallel passageways comprising a dam member which includes a central hole therein adapted to direct water from said first passageway through said filter device unfiltered, said second passageway adapted to direct water annularly within said chamber and around said dam member; d. a transverse member below said chamber and integral with said dam member comprising a plurality of annular holes; e. an upper transverse retainer member disposed within said bottom member and comprising a plurality of annular holes and a central hole; f. a lower transverse retainer member disposed within said bottom member and comprising a plurality of annular holes which include shoulder means and a central hole; g. a plurality of filter elements disposed longitudinally within said casing and retained therein within said annular holes of said transverse member and said upper and lower retainer members; h. said filter element having an open top and a plurality of lower openings adapted to retain a filter material within said element; whereby when one hole of said valve is aligned with said second parallel passageway, flowing water will be diverted annularly within said chamber and through said filter elements.
