Abstract
Approaches for desiccant device within an enclosure protecting sensitive electronic equipment. Electronic equipment, such as a hard-disk drive (HDD), may comprise a desiccant device a desiccant device that comprises a first desiccant material, a second desiccant material, and an activated carbon layer. The first desiccant material has a relatively high rate of water vapor absorption while the second desiccant material has a relatively low rate of water vapor absorption. The activated carbon layer absorbs airborne organic airborne particles. The desiccant device may be a breather filer or may be disposed entirely within the interior of the electronic equipment, e.g., the desiccant device may be a recirculation filter.
