Abrégé
(EN)

The present invention relates to an air filter which comprises a pre-filtration member (5) mounted in the flow direction upstream from a main filter member (4). A relatively thin layer of an adhesive or glue is applied on a fibrous support material of the pre-filtration member (5) or on diffusing blades. This adhesive or glue exhibits for a predetermined period of time a persistent adhesive effect for the particles to be filtered, essentially dust.
