ABSTRACT:
A filter element is placed over the inlet of a hose used to draw a vacuum on a bag that contains asbestos-containing materials collected during an asbestos removal process. The filter element is disposable and is removed from the hose as that hose is pulled out of the bag after the vacuum is drawn on the bag. The filter element is frusto-conical and one embodiment includes a rim located near one end thereof to assist in the removal of the filter element from the hose.
