A device for reducing a carbon dioxide and water content in an enclosed air volume has first and second sorption units for sorbing carbon dioxide and water. The first and second sorption units can be transferred from a sorption mode into a desorption mode and vice versa. In the sorption mode, the first and second sorption units sorb carbon dioxide and water from raw air of the enclosed air volume. In the desorption mode, the first and second desorption units desorb carbon dioxide and water to supplied regeneration air. An air distribution device can switch the first and second sorption units, based on the carbon dioxide and water content, alternately from sorption mode into desorption mode such that, in at least one operating state of the device, one of the first and second sorption units is in sorption mode while the other is in desorption mode.

Device for the combined reduction of the carbon dioxide and water or moisture content, motor vehicle, and method

A filter housing has a first housing part with a first rim section and a second housing part with a second rim section. The housing parts can be joined and separated from each other in axial mounting direction and define a housing interior for a filter element provided with a circumferentially extending sealing element. The first and second rim sections form a receiving area in which the sealing element is seal-tightly clamped radially between the first and second rim sections when the housing parts are joined in the mounted state. A snap connecting device axially braces the first and second housing parts relative to each other. The snap connecting device is formed integrally on the first and second housing parts such that a clamping force applied by the first and second rim sections on the sealing element in radial direction is decoupled from the snap connecting device.
