Abrégé
(EN) The invention relates to an air filter comprising a preliminary filter element (5) preceding a main filter element (4) in flow direction. A relatively thin layer of a sticking or adhesive agent is being spread on a fibrous base material of the preliminary filter element (5) or on so-called deflection blades, wherein said sticking or adhesive agent has a permanent adhesive effect on particles to be filtered, in particular dust, over a given period of time.
