Abstract
An air filter for filtering air within a closed housing, such as a disk drive, having spacers surrounding a disk driving hub between adjacent disks in which angular rotation of the disks generate a radial and rotational stream of air across the surfaces of the disks. The filter includes an annular ring of filter media supported by the respective spacer. The air stream generated by the angular rotating disks flows radially throughout the full 360.degree. of the filter media ring in an inward and/or outward direction.
