Abstract
A bottled water cooler has a bottle inverted into a cooling reservoir, and a double lipped gasket seals the bottle to the reservoir. Air is admitted, to permit water flow, through a conduit ending in a housing. The housing supports a removable, and replaceable, filter element carrying an extremely fine porosity filter medium. A check valve in the housing blocks the conduit unless the filter element is in place. The housing and conduit are mounted on the cooler cabinet in a shielded, but conveniently accessible, location.
