Abstract
A filter assembly for use in an air purifier unit having a rectangular shaped air inlet entrance to the unit blower. A rectangular shaped frame containing a HEPA filter pack is slidably received within the blower inlet. An L-shaped flange surrounds the filter frame and closes against the air inlet of the blower to provide an air seal. The top wall of the flange is offset some distance from an adjacent wall of the frame to provide a handle for the filter assembly.
