Abstract:
A filter assembly comprising:a primarily radial flow filter element comprising a substantially prismatic or cylindrical body of filtering material having a first end through which filtered water flows, and a second end opposite said first end;a substantially tubular siphon shield having cross-sectional interior dimensions greater than the exterior cross sectional dimensions of said filter element, said shield consisting of a single diameter wall comprising the exterior of said filter assembly;a mounting element which mounts said siphon shield around said filter element so that there is a siphon space between said filter element and said siphon shield;said siphon space cooperating with said siphon shield to significantly reduce the amount of air radially flowing through said filter element with water when parts of said filter element are uncovered by water; andwherein said filter element first end is operatively connected to a cap for closing the open end of a bottle, said cap having a manual valve associated therewith; and wherein said mounting element mounts said siphon shield adjacent said second end of said filter element so that water can substantially only flow into said siphon space from adjacent said first end of said filter element, and wherein said siphon space is readily accessible to water adjacent said cap.
