Abstract: The present invention provides a vacuum cleaner for cleaning a surface, wherein the vacuum cleaner comprises: a suction mouth for bearing against the surface; a chamber for receiving particulate material entering the vacuum cleaner through the suction mouth; a suction device for providing an air flow into the suction mouth; and a conduit connecting the suction mouth to the chamber, wherein the conduit comprises an adsorbent in the form of a honeycomb having a plurality of channels that are separated from each other by channel walls, and wherein the honeycomb adsorbent comprises activated carbon. There is also provided the use of an adsorbent in the form of a honeycomb in a conduit of the vacuum cleaner.

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.
