ABSTRACT:
An air filtration system includes a holding frame supported by a universal mounting frame and a cartridge in the holding frame. The holding frame has a header used to permanently mount and seal the holding frame to the universal frame. The filtration cartridge fits inside the holding frame and is easily replaceable. A seal is provided between the holding frame and cartridge to assure that air passing through the system passes through the cartridge. In a preferred embodiment, the seal is provided on a flange at the back of the holding frame and another seal is provided on a cover that holds the cartridge into the holding frame.
