A motor (17) moves air from the inlet (14) to the outlet (16) and a first filter (20) is between the inlet (14) and the outlet (16) for filtering air. An inner wall (30) and an outer wall (32) that is spaced apart from the inner wall (30) form a cavity (34) therebetween. The inner wall (30) has an inner opening (40) and the outer wall (34) has an outer opening (42). A back cover (44) is removably secured to the outer wall (34) over the outer opening (42) and has an access opening (46); an access cover (48) is removably secured over the access opening (46). A filter cartridge (60) is removably disposed within the cavity (34), the filter cartridge (60) has a first side (62) with a first opening (64) and a second side (66) opposite to the first side (62) and adjacent to the access cover (48) with a second opening (70) and a second filter (80) disposed therebetween the openings (64, 70).
