ABSTRACT:
A high efficiency particulate air filter, and a method of fabricating the same, are disclosed, with the filter being characterized by being lightweight and readily disposable after use. Further, the filter may be fabricated in a basic or universal form, which permits it to be utilized to form any one of a number of possible specific mounting configurations by the placement of one or more specifically designed headers about the outer periphery. The filter comprises a sheet of HEPA filtering media folded upon itself in accordion fashion to form a filter pack, and a relatively thin and lightweight peripheral frame surrounding and supporting the pack. The frame is composed of a relatively hard, crust-like, air impermeable molded material which is self-bonded and sealed to the filter pack to effectively preclude the leakage of air therebetween. Internal integral reinforcing ribs are formed in the material of the frame along at least two opposite sides of the pack, to provide sufficient strength to permit the filter to be mounted against a pressure seal or the like.
