ABSTRACT:
A disposable protective cover for face-engaging respirators, or the like, which is particularly useful in a contaminated environment in preventing particulate buildup on the respirator. For example, in painting operations the cover protects the respirator from paint buildup and contamination, preserving the respirator from undue wear and reducing frequent cleaning and maintenance of the respirator. The cover presents a thin, flexible body configured to generally conform to the shape of the outer surface of the respirator. The body has an opening to provide access to the respirator intake and a cuplike section to provide a loose fit of the cover around the respirator exhalation valve to allow unrestricted breathing. The covers hereof present structure for quick attachment or detachment of the covers from the respirator. The exact structural features of the covers are adapted to accommodate different types of respirators, such as full face or half-face masks, and external air source or filter type masks.
