Filter for vacuum cleaner

DETAILED DESCRIPTION AND ADVANTAGES The present invention relates to a vacuum cleaner assembly comprising a main housing having an inlet and an outlet.
A motor is disposed within the main housing between the inlet and the outlet for providing motive force to a cooling fan, a blower, and a separator.
The cooling fan is mounted within the main housing above the motor to circulate cooling air around the motor.
A baffle is mounted within the main housing for directing the cooling air around the motor, and to filter the air that is circulated around the motor before that air is exhausted.
The blower is mounted within the main housing below the motor for drawing air into the inlet and exhausting air outwardly through the outlet.
The separator is mounted below the blower for circulating the air and water within a water bath and providing, in combination with the water bath, a primary filter for filtering the air prior to exhausting the air outwardly through the outlet.
A second filter is a high efficiency filter for filtering microscopic dust and dirt particles that escape the separator and water bath and is disposed after both the water bath and the separator and before the outlet for additional filtering of the air prior to being exhausted.
The second filter is disposed in a recess which is integral with the main housing allowing for direct and efficient flow of the air through the water bath, separator and second filter.
Accordingly, the present invention will utilize the separator and water bath filter to capture the larger particles of dirt and debris prior to routing the air through the second high efficiency filter to capture microscopic particles that escape the water bath.
The recess for the high efficiency filter is located integrally to the main housing allowing the air to flow directly from the water bath canister through the high efficiency filter with minimal redirection of the air and no noticeable impact on the primary filter.
This will allow the air to flow smoothly through the series of filters
