摘要

Filter device for the elimination of suspended matter, such as, for example, grease, readily volatile components and / or odorous substances from an air stream, with a housing body (1), in which an air channel (2) with an air inlet opening (3) and an air outlet opening (4) is formed, and provided with a plasma source (7) for generating a plasma in the air stream, the inside of the air channel (2) is arranged, characterized in that, when viewed in the direction of air flow in front of the plasma source (7) in the air duct (2) is an air flow - rectifier (6) is arranged, in order to provide an air stream before its entry into the plasma source (7) and thus to be aligned in the air channel laminar air flow (l_l) to be produced, which is a uniformly in the longitudinal direction of the air channel (2) flows.
