Abstract: A disposable bag for removal of dust vacuum cleaners comprised of a nonporous polymer composition sheeting sealed water tight for internally containing a quantity of water that functions as the dust removal media. The bag is configured for mounting internally within the external fabric bag customarily provided by the vacuum cleaner manufacturer. Discharge of dust laden air from the vacuum blower is connected to an air inlet on the bag from which an internal guide directs the air flow to within the body of water. Emerging from the water substantially dust free, the air is directed past baffles to eliminate entrained moisture before being discharged through an outlet opening to the surrounding environment.
