A vacuum cleaner assembly (10) includes a main housing (12) having an inlet (14) and an outlet (16). A motor (17a) is disposed within the main housing (12) for providing motive force to a cooling fan (17b), a blower (17c), and a separator (22). The separator (22) circulates the air and water bath (20) within a water bath pan (36) and provides, in combination with the water bath (20), a primary filter for filtering the air. A second filter assembly (24) is also provided preferably including a high efficiency filter (100 or 100a), or HEPA rated 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) for additional filtering of the air. Alternatively, it may be a non-HEPA rated filter (101). The second filter assembly (24) may also include a third filter element, which may be a carbon impregnated filter (110) for absorbing or trapping odors and is disposed in the air flow path after the second filter (100, 101, or 100a). The second filter (100, 100a or 101) and third filter (110) element are secured in a frame (112) as part of the second filter assembly (24). The second filter (100, 101 or 100a) and the carbon impregnated filter (110) within the frame (112) are 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 assembly (24).

[ What is claimed is:] [1.] A vacuum cleaner assembly comprising:a main housing having an inlet, a recess remotely disposed from said inlet and integrally formed within said main housing, and an outlet positioned within said recess,a motor disposed within said housing between said inlet and said outlet for providing motive force to said vacuum cleaner assembly components,a fan mounted within said main housing driven by said motor for circulating air around said motor,a primary filter system for filtering of the air prior to being exhausted outwardly through said outlet,a secondary filter system placed in downstream airflow from said primary filter system, removably positioned within said recess and aligned with said outlet for additional filtering of the air prior to being exhausted outwardly through said outlet. [18.] A method of filtering air through a vacuum cleaner, comprising the steps of:(A) drawing air into a vacuum cleaner housing;(B) drawing air into a water bath to filter dirt and dust particles;(C) filtering particles of dust and dirt from the air through a separator;(D) filtering smaller particles of dust and dirt from the air through a first filter; and(E) filtering odors from the air through a carbon filter. A vacuum cleaner assembly comprising:a main housing having an inlet, a recess integrally formed within said main housing, and an outlet positioned within said recess,a motor disposed within said housing between said inlet and said outlet for providing motive force to said vacuum cleaner assembly components,a fan mounted within said main housing driven by said motor for circulating air around said motor,a primary filter system for filtering of the air prior to being exhausted outwardly through said outlet,a secondary filter system placed in downstream airflow from said primary filter system and positioned within said recess directly adjacent said main housing outlet to allow the air to flow directly from said main housing outlet into said secondary filter system.
