Abstract
A filter cartridge is provided. The filter cartridge includes a filter element comprising a filter media, and the filter element extends between an inlet face and an outlet face. The filter element defines a periphery surrounding the filter media. The filter cartridge also includes a border frame including a plurality of side panels, and the side panels are independently molded-in-place along the periphery of the filter element. Adjacent members of the side panels are joined together along a plurality of mold interface seams, and the mold interface seams are spaced around the periphery. The plurality of side panels are embedded in and seal the periphery of the filter element such that fluid flow inside the border frame is directed to pass through the filter media for filtering in order to pass from the inlet face to the outlet face.
