Abstract
A respirator including a mask body with a breathing filter at a breathing connection of the mask body, with a cuff accommodating the breathing filter and with a bellows, which seals the mask interior against the environment. The bellows is connected to the cuff and to the mask body. The breathing filter is locked in the position of use based on the bellows being made in one piece with the breathing connection, as a continuation of the mask body. The bellows surrounds the cuff in the manner of a truncated cone, in at least one partial section of the extent of the breathing filter.
