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 diffiusion 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.
