Abstract
The respirator comprises a mask (1) with two layers (7,13) of different filtering materials arranged on it and elements for its securing to the face. The respirator is provided with an exhalation valve (3) detachably secured in an opening of themask. One layer (7) of the filtering material possesses aerosol filtering properties and is secured outside the mask by a bracing cord (10). The valve projects outside the filter material layer. The edge (8) of this layer is folded over the edge of the mask and is braced by the cord. The second layer (13) of filtering material possesses chemisorption gas absorptive properties and is secured inside the mask so that its edge fits the edge of the first layer and the valve projects from the second layer (13) inside the mask.
