Abstract
A filter assembly having first and second opposite frame members and a filter element removably secured to the first and second frame members is provided. The filter element is preferably a pleated paper filter, positioned in extension between opposite end panels. An arrangement is provided for securing the end panels to, and in extension between, the first and second opposite frame members. When the arrangement is assembled, an outer frame comprising the two frame members in the two end panels is provided. In the assembly, the pleated filter fills the area within the frame. The filter media can be conveniently removed and replaced in the frame, as desired.
