Abstract

A filter cartridge for filtering fluid, such as air, within an enclosed housing, such as a disk drive, comprises a toroidal body having a pair of mating confronting halves fastened together. A pair of annular sheets of filter media are sandwiched between the halves and are separated by a ring member to engage each sheet of filter material against a respective one of the confronting halves. Fluid to be filtered flows radially through the cartridge to flow through at least two portions of the filter media. Optionally, a third sheet of filter material may be supported by the ring member to provide additional filtering.
