ABSTRACT OF THE DISCLOSURE The present invention provides a filter cover assembly for use with the filter of a respirator. The semi-rigid filter cover assembly fits snugly over the face of the filter and, with the use of a one-way valve assembly mounted therein, allows the user to continue using the respirator while at the same time containing any contaminated particulate matter that may fall out of the filter. This permits the user to continue using the respirator while in a decontamination zone without danger of dispersing contaminated matter. It also permits easy handling and storage of the filter between uses without necessitating the cleaning of the filter.
