An adsorptive filter/member for adsorbing a gaseous adsorbate. The filter includes two layers of a flexible polymeric material to form an area therebetween. Fasteners are located at predetermined areas across the two layer outer surfaces, the fasteners extending from the outer surface of one layer
An adsorptive filter/member for adsorbing a gaseous adsorbate. The filter includes two layers of a flexible polymeric material to form an area therebetween. Fasteners are located at predetermined areas across the two layer outer surfaces, the fasteners extending from the outer surface of one layer to the outer surface of the other layer. The fasteners subdivide the area into a plurality of substantially enclosed chambers. Adsorptive media is disposed within each of the plurality of chambers. The chambers are adapted to substantially evenly distribute adsorptive media throughout the filter. Throughbores extend through the filter, and receive attachment members for mounting the filter to a surface. A gaseous adsorbate flow path is in gaseous communication with one of the outer surfaces of the two layers. Each of the two layers' polymeric materials includes pores that are permeable to the gaseous adsorbate, yet are substantially impermeable to the adsorptive media.
