An air filter assembly for removing particulate matter from an incoming dirty air stream. The assembly includes a housing having an inlet, an outlet, a dirty air chamber and a clean air chamber and an elongated filter element arranged within the dirty air chamber constructed to remove particulate matter from an incoming air stream. The dirty air chamber has side walls, at least one of which is non-planar and has a distended portion. The distended side wall increases the volume within the dirty air chamber, thus providing for increased dirty air processing and/or decreased dirty air velocities.
