ABSTRACT:
A process for the manufacture of hermetically sealed filter units and a product made thereby. The process comprises aligning a porous filter element between two housing parts and a thermoplastic skirt that overlaps the edge of at least one housing part to shield the edge of the filter element disposed adjacent to the skirt, pressing the housing parts together and then injection molding a thermoplastic overmold band around the outer portions of the housing parts to form a hermetic seal at the edge of the filter element.
