Patent ID: 7377966

Claim:
An adsorptive filter for adsorbing a desired gaseous adsorbate, comprising: a first layer of a flexible polymeric material having an outer surface; a second layer of a flexible polymeric material spaced from the first layer to form an area between the first and second layers, the second layer having an outer surface; a plurality of fasteners located at predetermined areas across the first and second layer outer surfaces, the plurality of fasteners extending from the outer surface of the first layer to the outer surface of the second layer, wherein the plurality of fasteners subdivides the area into a plurality of substantially enclosed chambers; a predetermined amount of adsorptive media disposed within each of the plurality of substantially enclosed chambers, the plurality of substantially enclosed chambers adapted to substantially evenly distribute the adsorptive media throughout the filter; a plurality of throughbores extending from the outer surface of the first layer to the outer surface of the second layer, and adapted to receive attachment members for mounting the filter to a desired surface, the plurality of throughbores located on the attachment members and the plurality of throughbores being formed from a spot weld of a portion of the first layer to a portion of the second layer; and a gaseous adsorbate flow path in gaseous communication with one of the outer surfaces of the first and second layers; wherein each of the first and second layer polymeric materials include pores that are permeable to the desired gaseous adsorbate, and wherein each of the first and second layer polymeric materials pores are substantially impermeable to the adsorptive media.
