Abstract:
An escape mask that enables one to breathe filtered air includes a foldable pocket size hood to cover the entire head, including a bag made of transparent plastic film material impermeable to gases, a multi-layered filter assembly containing at least one filter layer containing an antiseptic effective against microorganisms and at least one filter layer containing activated charcoal, the filter assembly being adhered to the bag over an aperture in the bag in the area where the mouth and nose would be for someone wearing the mask, and an exhalation valve embedded in the filter assembly.
