Electronic enclosure filter for very small spaces

The present invention is directed to an improved electronic enclosure filter for very small spaces, such as small disk drives. The filter includes an exposed electrostatic layer that functions to catch and retain particulate contamination within the filter. The filter can be placed within disk drive enclosures such that the electrostatic layer is in very close proximity to the rotating disk without causing excessive turbulence. The close proximity of the electrostatic layer to the disk creates relatively high levels of airflow over the electrostatic layer.
