Abstract
A secondary air filter assembly that can be attached to the exhaust port of an upright vacuum cleaner is provided. The assembly includes an adapter plate that is adhered, clipped or otherwise affixed to the exhaust port, and a filter carrier that is removably attached to the base. The filter is preferably affixed as a unit to the filter carrier so that the entire filter/carrier unit can be replaced at once. The adapter base can also be used as an attachment for other accessories.
