    摘要： A filter assembly for a vacuum cleaner that includes a main housing having an inlet and an outlet. A motor moves air from the inlet to the outlet, and a first filter is arranged between the inlet and the outlet for filtering the air. An inner wall and an outer wall that is spaced apart from the inner wall form a cavity between the walls. The cavity is located between the first filter and the outlet. The inner wall has an inner opening that permits air to flow from the first filter into the cavity, and the outer wall has an outer opening. A back cover is removably secured to the outer wall over the outer opening to seal the cavity and guide the air from the cavity to the outlet. The back cover includes an access opening that is removably secured to the back cover over the access opening to seal the access opening. A filter cartridge is removably disposed within the cavity. The filter cartridge has a first side with a first opening and a second side opposite the first side and adjacent to the access cover with a second opening. The filter cartridge has a second filter, such as a HEPA filter, disposed therein between the first and the second openings for further filtering the air. A portion of the first side is in sealing engagement with a portion of the inner wall such that the first opening is aligned with the inner opening wherein the motor moves the air from the inner opening to the second opening.

    摘要： A vacuum cleaner assembly (10) comprising a main housing (12) having an inlet (14) and an outlet (16). A motor (17a) is disposed within the main housing (12) between the inlet (14) and the outlet (16) for providing motive force to a cooling fan (17b), a blower (17c), and a separator (22). The cooling fan (17b) is mounted within the main housing (12) above the motor (17a) to circulate cooling air around the motor (17a). The blower (17c) is mounted within the main housing (12) below the motor (17a) for drawing air into the inlet (14) and exhausting air outwardly through the outlet (16). The separator (22) is mounted below the blower (17c) for circulating the air and water bath (20) within a water bath pan (36) and providing, in combination with the water bath (20), a primary filter for filtering the air prior to exhausting the air outwardly through the outlet (16). A second filter (24) is a high efficiency filter for filtering microscopic dust and dirt particles that escape the separator (22) and water bath (20) and is disposed after both the water bath (20) and the separator (22) and before the outlet (16) for additional filtering of the air prior to being exhausted. The second filter (24) is disposed in a recess (26) which is integral with the main housing (12) allowing for direct and efficient flow of the air through the water bath (20), separator (22) and second filter (24).
