Abstract
A drinking water purification system includes a flat filter assembly which may be installed in relatively narrow spaces which would otherwise be wasted such as the space beside a kitchen cabinet and the basin of a kitchen sink, inside a freezer door or on a countertop. The filter assembly includes a housing, preferably U-shaped, having a plurality of transversely extending ribs, formed in the opposed side walls of the housing, which reinforce the housing and which cause a generally serpentine flow of water through the housing during operation of the filter. Protrusions preferably are formed in the housing in addition to the ribs to strengthen further the housing and to aid in preventing the formation of channels through the granulated filter medium contained within the housing. Internal or external quick connect couplers preferably connect the filter assembly to a source of untreated water and to a dispenser. An especially preferred external coupler includes an integral support element and devices for preventing water leakage when the filter assembly is disconnected from the coupler.
