Abstract
A filter assembly for use with a bottle having a substantially circular cross-section neck or open end includes a cap for closing the bottle neck or open end including an upper surface, and a manual valve associated with an outer substantially liquid impermeable housing may be operatively connected to the cap at an upper end of the housing and has a number of substantially radially extending openings adjacent the upper end portion to allow liquid to flow into a substantially annular open cavity within the housing. The cavity substantially radially surrounds an inner at least primarily radial flow filter element, such as a carbon/plastic matrix which removes chlorine from drinking water. A treating element is positioned so that water flowing through the openings and into the cavity is treated, either by removing contaminants from the water, or by chilling it. The treating element may comprise an axial flow liquid porous treating media such as granules of ion exchange resin, or may be a micro-porous filter element through which liquid flows radially into the open cavity, or may be a water chilling element that chills water in the open cavity.
