Abstract
A filter assembly for a disk drive includes an outer shell through which gases flow in and out of the disk drive. The shell includes a tubular housing that extends into the disk drive. A first filter lies secured to an end portion of the housing and filters gases circulating within the disk drive and entering into the disk drive. The housing contains a second filter that includes an adsorbent body and a third filter that extends across an opening in the housing and helps contain the second filter within the housing.
