ABSTRACT:
A respirator mask with a respirator filter and bellows sealing off the interior space of the mask against the surrounding atmosphere, which bellows surround the respirator filter at its end facing the interior space of the mask in the form of a rigid cuff, is to be improved such that replacement of the respirator filter will be simplified. To accomplish this task, the cuff (7) is continued in an elastic sleeve (8) nearly completely surrounding the respirator filter (2), and, with the sleeve (8) folded back, the respirator filter (2) can be inserted into or can be removed from the cuff (7).
