A filter assembly is formed of an impervious elongated tubular housing and an elongated filter member positioned within the housing with its opposed longitudinal edges sealed to the housing internal tubular surface. A first barrier is interposed between the filter member first surface and the housing internal tubular surface adjacent the housing inlet end and a second barrier is interposed between the filter member second surface and the housing internal tubular surface adjacent the housing outlet end. Air flowing into the housing inlet end passes through the filter member before exiting at the outlet end. |
