Abrégé
(EN) An air filter having a preliminary filter element (5) arranged upstream of the main filter element (4), characterized by the fact that on a fibrous support material of the preliminary filter element, a relatively thin layer of bonding agent or adhesive agent is applied to the fibre structure, with said adhesive agent having for a predetermined filtering cycle a persistently adhesive effect concerning particles to be separated, in particular dust, the preliminary filter element is spaced from the main filter element and can be removed separately from the housing of the air filter, and the particles adherent to the adhesive agent can be removed upon the predetermined filtering cycle either mechanically or by washing off the same. 2126 ה' בחשון התשס" ד - October 31, 2003
