Abstract
A hard disk drive recirculation filter is disposed on a housing surface of a disk drive assembly oriented adjacent to one or more disk surfaces. In one embodiment, the recirculation filter is a pocket filter having a filter support component and a filter element. The filter support includes an inlet, a top surface and a bottom surface, where the bottom surface is used to adhere the pocket filter to the housing surface. The top surface is adapted to adhere the filter element thereto, thereby forming a pocket into which rotationally-induced airflow may enter.
