Abstract

A compact sorbent filter for selectively sorbing contaminants and method of removing contamination from an enclosure with a filter is disclosed The filter comprises a sorbent core including contaminant adsorbing material therein an outer protective cover wrapped around the inner sorbent core so as to completely contain the sorbent core, with the exposed end(s) of the core being capped so as to encapsulate the sorbent core present within the filter while not limiting the amount of material contained therein. A sorbing filter isplaced within an enclosure to remove gaseous contamination therein. The filter is particularly suitable for use in a computer disk drive or similar enclosure where out-gassing contamination may be a problem.
