ABSTRACT:
A filter assembly includes a reusable filter frame and a collapsible and expandable filter element. The filter frame includes a base and a cover connected with the base. The base includes a plurality of longitudinal rails and a plurality of transverse ribs for supporting and spacing the filter element. The filter frame also includes a securing mechanism for securing the filter element to the frame and maintaining the filter element in its expanded condition. The filter element includes filter media having a plurality of pleats adapted to mesh with the ribs of the filter frame and a flexible spacing structure attached to the pleated media that provides the pleated media with uniform pleat spacing but allows the media to be collapsed to a compact form.
