Abstract: A cartridge for a breathing mask is provided with a housing and an adsorption filter section arranged in the housing. The adsorption filter section is provided with one or more carrier media and one or more activated carbon layers with activated carbon particles. The activated carbon particles are immobilized in the activated carbon layers by a fixation agent. A fine filter section is arranged fluidically upstream of the adsorption filter section and separates contaminants from the breathing air. The cartridge has a flow-through connecting element and the breathing mask has a flow-through counter element, wherein the connecting element and the counter element interact to connect the cartridge to the breathing mask. The breathing mask has a shut-off element that fluid-tightly close off the counter element when the cartridge is removed from the counter element.
