Disclosed is a device for scrubbing carbon dioxide-contaminated gas for use in a fuel cell. The device comprises at least one first opening for allowing gas to enter or exit the device, at least one second opening for allowing gas to exit or enter the device, and at least one sorbent that is capable of removing carbon dioxide from the gas and is arranged in a form of layers which the gas contacts when it flows from the first to the second opening. The device may further comprise one or two gas preparation units for removing solid and/or liquid contaminants from the gas and for adjusting the temperature and/or humidity of the gas.

A filtering method and a filter device () for removing impurities from the breathing air () in a room, an air raid shelter or a vehicle. According to the filtering method, the air to be filtered is driven through a carbon dioxide filter () by a fan (), with the result that at least a portion of the carbon dioxide and/or mold spores and other impurities in the air are trapped in the carbon dioxide filter. After the filtering, the filter is regenerated and the carbon dioxide and/or mold spores trapped in it are removed by a technique whereby air heated by a thermal resistor () is passed through the filter, this air preferably consisting of the same air to be filtered.
