Abstract: A mobile purification device for purifying indoor air and/or fresh air, has a holder and a filter element having a particle-filtering and a gas-adsorbing region, the particle-filtering region having a filter medium and the filter element being received in the holder to purify indoor air and/or fresh air containing smoke and/or particles and is useful as a mobile purification device, filtering particle-polluted and/or smoke-polluted indoor air and/or fresh air as effectively as possible, with particulate, emitted contaminants being prevented as far as possible from being discharged from the gas-adsorbing region into a space, wherein the particle-filtering region faces a downstream side of the holder and in that the gas-adsorbing region faces an upstream side, which can be supplied with indoor air and/or fresh air polluted with smoke and/or particles.
