ABSTRACT:
The present invention provides for a method of manufacturing a filter assembly having a filter frame member (402) and the filter assembly (500) produced thereby. The method includes the step of supporting a filter media (202) preferably using a pair of support members (102 and 204). The support members (102 and 204) hold the filter media in place and allow portions of the filter media (202) to be exposed around the media's periphery. Next, a filter support frame (402) is placed around and in proximity to the exposed filter media. The filter support frame (402) is then welded, preferably ultrasonically, to the exposed portions of the filter media. Once welded, the pleated filter assembly is removed from the support members (102 and 204).
