Abstract: A method for filtering odors out of an air flow during which an air now containing odorous substances is guided through a filtering device equipped with an odor filter, whereby the odor filter has activated carbon or a similar substance serving as filtering material. As an additional method step, the inventive method provides that the particles contained in the air flow are at least partially ionized and/or dissociated before entering the odor filter.

Abstract: An ionizing device for air treatment systems includes two electrodes that can be connected to a high-voltage source generating an AC voltage and between which a dielectrically encumbered discharge can be induced for generating a plasma, wherein each electrode includes a deformable shape having an electrical conductor encased in a dielectric material and wherein the two deformable shapes are fixed relative to each other such that the two deformable shapes contact each other at least in areas or have a small enough distance from each other that they can induce the dielectrically encumbered discharge.

Abstract: A method is provided for cleaning a hot air stream, wherein the air stream is conducted through a cooling device and then through a filter device, which includes at least one plasma production device for removing gaseous organic carbon compounds. The cooling device cools the hot air stream to temperatures below 60° C. The air stream to be cleaned is accelerated before entering the filter device and is deflected by means of suitable guiding surfaces. A cleaning device is provided for a hot air stream and includes a filter device with a plasma production device for removing gaseous organic carbon compounds and a cooling device connected upstream of the filter device. The cooling device includes a spraying device for a coolant. The filter device includes an open-pored hydrophilic foam material, the plasma production device and a suitable absorber material, through which the air stream flows consecutively.
