Abstract
A breather bag filter assembly for use with an electronic enclosure, such as a hard disk drive enclosure containing a rotating disk, is disclosed. The filter assembly provides filtration of air entering and exiting an electronic enclosure through a breather hole. The filter assembly is a deformable sealed cavity that exchanges air with the drive enclosure as the air pressure inside the drive enclosure fluctuates. In one implementation of the invention the filter assembly contains three layers of material. Two layers of material form the exterior of the filter assembly surrounding a third layer that is composed of an adsorbent material.
