摘要：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 filteringmethod, the air to be filtered is driven through a carbon dioxide filter () by a fan (), withthe result that at least a portion of the carbon dioxide and/or mold spores and otherimpurities in the air are trapped in the carbon dioxide filter. After the filtering, the filter isregenerated and the carbon dioxide and/or mold spores trapped in it are removed by atechnique whereby air heated by a thermal resistor () is passed through the filter, this airpreferably consisting of the same air to be filtered.
