ABSTRACT:
A pour-through pitcher filter assembly includes a compact filter element including a thin annular disk of molded activated carbon and a peripheral annular seal element. The seal element allows the filter to be replaceably mounted in the lower end of a plastic reservoir, which reservoir is adapted to be supported in the top of a pitcher for receiving filtered water. The reservoir may be made by a blow molding process and includes an integral bellows member which is manually collapsible to pressurize the interior of the reservoir to initiate gravity flow through an initially dry filter element. The seal element utilizes a synthetic rubber material and is preferably insert molded around the carbon filter disk.
