A combination filter system for an enclosed disc drive in which a breather filter is provided in a central position in the disc drive cover and a recirculating air filter is concentrically positioned about the breather filter. The recirculating filter includes an annular air deflector whereby air flowing from the periphery of the disc housing is filtered and directed towards the spindle, which is positioned in the central opening of the annular air deflector, thereby establishing continuous flow of filtered air within the housing.
