ABSTRACT:
An adsorbent filter including compression molded particulate adsorbent construction is provided. The compression molded particulate adsorbent construction contains a particulate adsorbent and a sufficient amount of binder to retain the particulate adsorbent in a non-free flowing form. The adsorbent filter preferably includes a compression molded particulate adsorbent construction as described, positioned within an outer, porous cover. Preferably the outer, porous cover includes expanded porous polytetrafluoroethylene. In certain preferred applications, the adsorbent filter is positioned within a housing defining an internal volume and including therein electronic component(s), such that the adsorbent filter protects the internal volume of the housing, and components therein, from damage. The typical application is as a disk drive adsorbent filter. A preferred method for preparing an adsorbent filter according to the present invention is provided.
