The filter assembly is configured to remove contaminants within the drive assembly and to prevent entry of contaminants into the drive assembly. In one implementation the filter assembly includes a housing configured for placement in a disk drive assembly containing a rotating disk, the housing including an air scoop having an entrance configured for placement beneath the rotating disk in the drive assembly; and a major surface having a wall and an opening in the wall, the opening configured for receiving a filter material and being in fluid communication with the entrance to the air scoop. A filter element is positioned within the housing and configured so that a first portion of the element filters air directed from the air scoop, while a second portion of the element filters air from the exterior of the drive assembly, the first and second portions sealed by a common filter material placed over the opening in the major surface.
