Abstract

A novel filtration device having a substantially rigid frame comprised of an outer peripheral band connected by a plurality of spacers to an inner breather tube, wherein filter pads are secured over both sides of the frame and separated by the spacers to form an enclosed central air pocket accessible only through the breather tube. The breather tube is adapted to be detachably connected to an inlet port in a respirator face mask so as to provide a closed channel for air flow from the central air pocket to the interior of the face mask.
