Abstract
A cartridge including a sheet of filtering media in annular form through which air is passed as it moves in a generally toroidal path within an enclosed housing due to rotation of a computer tape disc, or the like, mounted adjacent the cartridge within the housing. The cartridge includes a rigid body portion supporting the filter media in a generally conical plane within the annular body. The body portion is initially formed as two separate, mating halves which engage the media about its inner and outer peripheries when joined.
