Abstract

A disposable canister containing a HEPA filtration mechanism is used in conjunction with a removably mounted vacuum motor assembly. The vacuum motor assembly draws particulate-laden air, including harmful airborne contaminants, into an inlet opening of the canister by a disposable vacuum hose. The inlet opening is made of a magnetically attracting material. The particulate-laden air is then filtered through the HEPA filtration mechanism prior to exiting from the canister as non-contaminated air. Upon termination of the vacuum force on the inlet, a hinged magnetic flap seals the inlet to the canister. The immediate and complete sealing of the inlet by the magnetically biased flap assures against escape of harmful contaminants from the canister.
