In a device having a surface which may be oriented in a downwardly facing attitude, an adsorbent cartridge comprising a casing including a substantially rigid self-sustaining dish-shaped first side having a central portion and an outer portion lying outwardly of said central portion, a second side of permeable sheet material secured relative to said outer portion of said dish-shaped first side, adsorbent in said casing confined between said first and second sides, and mounting means on said central portion of said first side for mounting said casing with said first side in contiguous relationship to said surface and with said second side facing away from said surface and exposed to the environment proximate said surface, said mounting means comprising an elongated shell-like member extending toward said second side from said central portion, said shell-like member having first and second ends, said first end being secured to said central portion of said dish-shaped first side, and a bearing surface on said second end, said self-sustaining substantially rigid first side maintaining said casing in its fabricated contour and said second side of permeable sheet material permitting gases to pass therethrough into said cartridge.
