Abstract
A respirator mask with connection openings for filters and a mask body, which is designed as a full mask or as a half mask, is improved such that subsequent conversion into one respirator mask configuration or another will be simplified and possible without the use of separate closing parts. To achieve this, a connecting adapter (2) with connecting ports (4, 10) can be fastened in at least two preferred positions on the full mask or half mask (1). A predetermined number of connection openings 8, 9 and connecting ports (4, 10) overlap in each preferred position. Various numbers of filters 3 can be connected to the overlapping areas, and the non-overlapping connection openings 8 are closed with sealing means 7 provided on the connecting adapter 2.
