Abstract: A filter for removing contaminants from an electronic enclosure. The filter includes fluted filter media for increasing the filter surface area. The filter may be configured in a flow by configuration or a flow through configuration. The filter may further include a scrim. A disk drive assembly includes an enclosure, a disk rotatably mounted within the enclosure, and a filter, where the filter is constructed from fluted filter media.

Abstract: A multiple diffusion channel filter assembly is disclosed. The filter assembly provides filtration of air entering and exiting an electronic enclosure through a breather hole. In one implementation of the invention the filter assembly contains a housing with an adsorbent component and a first diffusion channel and a second diffusion channel. The first diffusion channel is configured and arranged to provide fluid communication between the interior chamber of the housing and the inside of the electronic enclosure. The second diffusion channel is configured and arranged to provide fluid communication between the interior chamber of the housing and the exterior of the electronic enclosure. In another implementation of the invention the filter assembly contains a first layer and a second layer which surround an adsorbent component and a first and a second diffusion channel that are in fluid communication with the interior space defined by the first and second layers.

Abstract: A filter assembly includes a shaped adsorbent article disposed in a housing. The shaped adsorbent article has one or more projections extending from a surface of the article toward the housing to provide for flow of fluid between the shaped adsorbent article and the housing. The filter assembly may optionally include a diffusion channel for additional filtering and/or one or more porous polymer films disposed over inlet or outlet openings in the housing to reduce or prevent particulate contamination. The filter assembly may be used in a device, such as a computer disk drive, to filter a fluid, such as air, within and/or entering or exiting the device.
