Abstract

Filters, methods, and an apparatus for filling housings and both encapsulated porous and non-porous spaces with contaminant control media for placement in electronic enclosures, such as disk drive enclosures, are disclosed. In one embodiment, a filter assembly includes a housing comprising an internal cavity configured to receive contaminant control media, a fill port in communication with the internal cavity, and an opening in communication with the internal cavity, and filter media at least partially covering the opening; and contaminant control media occupying the internal cavity. Contaminant control media is deposited within the internal cavity via the fill port by means of creating a negative pressure within the internal cavity. The application of a partial vacuum facilitates movement of the contaminant control media into the internal cavity and minimizes the contamination of the filter, housing, and work space common to other loose fill filling methods. Other aspects and embodiments are provided herein.
