ABSTRACT:
Exposed components, including an exhalation valve, of a respirator mask are protected from extremely cold temperatures by a bag containing them, with its open end held in sealing engagement with the portion of the mask adjacent the components by means of a flexible collar. The bag is provided with an air inlet and with air outlets isolated from the inlet for escape of exhaled air from the bag. When one of the mask components in the bag is a filter, its inlet side is covered by an air-permeable base portion of the bag, and the rest of the bag is made of air-impermeable material, with the junction of the two parts of the bag sealed against the filter.
