ABSTRACT:
A sealed filtration cannister including a filtration mechanism sealed within the cannister. A prefilter and a HEPA filter entrap asbestos-containing dust within the sealed cannister. Upon usage of the filtration cannister for a predetermined number of hours, the cannister is disposed of in its entirety. The cannister is used in conjunction with a separate vacuum cleaner device having a suction hose communicating with a cannister lid removably mounted on top of the cannister. Alternately, the cannister is used with a portable vacuum motor assembly removably mounted on top of the cannister to provide independent suction to the filtration cannister.
