A filter including a base portion along with a flange extending from the base and a top surface plus a bottom surface is disclosed. The filter also includes an outlet. During use the filter is placed within an electronic enclosure, generally with the bottom surface in contact with the wall of the enclosure. The wall of the enclosure has an inlet through which gases can travel into the interior of the filter, and then eventually leaving the filter by way of the outlet, which is within the interior of the electronic enclosure.

Filter for electronic enclosure

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.
