A dust collection system includes a housing defining an inlet and an outlet. A fan is situated within the housing to move air from the inlet to the outlet, and a filter is removably attached to the housing to collect dust entering the housing. To prevent dust from escaping the filter when it is removed from the housing for cleaning or disposal a cover is removably attached to the filter when it is desired to remove the filter. To insure the cover is available the next time it is necessary to remove the dust-laden filter, the cover may be attachable to the housing for storage thereon.
