Abstract
A hand-held portable vacuum having a filter indicator that is coupled to an outlet housing and in fluid communication with a portion of the outlet housing between a fan inlet and an intake. The filter indicator includes a pressure differential indicator that is configured to indicate a pressure differential between air in the portion of the outlet housing and atmospheric air pressure. The filter indicator is employed to indicate to the user of the hand-held vacuum that replacement and/or cleaning of the filter is required. The vacuum may also be used in a blower mode with a set of inflator nozzles to permit a user to inflate an article.
