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.

Abstract: A filter element for filtration of an air stream includes: a folded filter medium forming a bellows, the filter medium being constructed at least in two layers and having a particle filter layer, an electrically conductive filter layer, and at least one edge band, the at least one edge band being connected to at least one outer side of the bellows. At least one further edge band is connected to an outer side of the bellows. The at least one further edge band is electrically conductive. The at least one further edge band forms a pocket open towards one side.

Abstract: A filter medium for filtration of an air stream includes: a non-woven having a plurality of bicomponent fibers. The non-woven includes a single-layer fiber composite having a first structure of bicomponent fibers and a second structure of continuous bicomponent fibers. The second structure engages with the first structure. In an embodiment, the bicomponent fibers include at least two polymer components. The at least two polymer components of the bicomponent fibers differ in melting point by at least 15 degrees and have a cover-core fiber structure or a side-by-side fiber structure.
