▎ 摘　　要

NOVELTY - The enclosure has a data storage disk that is arranged within an enclosure, where the enclosure is hermetically sealed. Heads reads or writes data onto the data storage disk. A filter (110) is in fluid communication with an interior of the enclosure, where the filter is a recirculation filter. The filter comprises filter media (116) that includes activated carbon and graphene, where the graphene is in the form of graphene particles having a dimension in range of 2 to 20 microns, and the filter comprises from about 0.5 to 20 wt. % of graphene per total weight filter media. USE - Enclosure for an electronic device i.e. hard disk drive (HDD). ADVANTAGE - The enclosure utilizes a volatile-chemical-adsorbing graphene with a water vapor-adsorbing carbon-type adsorbent to improve performance of carbon-type adsorbent by preventing the carbon-type adsorbent from contacting and adsorbing volatile chemical contaminant, thus allowing the carbon-type adsorbent to maintain a higher capacity to adsorb moisture. The enclosure can be sealed to prevent dust and external sources of contamination from entering the interior of the enclosure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for removing contaminants from an enclosure. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a filter.
