ABSTRACT:
A filter device, usable as a self-contained or freestanding unit or in association with an associated air treatment installation such as a furnace or air conditioner.
A preferred embodiment has a housing in which is supported a parallel-arranged plurality of filter bags folded over to achieve high filter area in comparison to the size of the housing; and ductwork leads the incoming air to the filter bags, which are formed of HEPA paper for screening out even extremely small particles.
The housing is hermetically sealed; and there is provided a blower for drawing in air, and causing it to pass through the filter bag system and into the interior of the housing, and then out the housing outlet for entrance to the associated air treatment installation.
Other features include a magnetic feature for connecting individual ones of the filter bags separately to the duckwork, and for holding them tightly to the ductwork, yet they are easily releasable when filter bag-change is needed, a condition shown by a pressure gauge responsive to pressure in the manifold by which the air to be treated passes in its route to the filter bags.
