The filter device (10) comprises a filter element (12) including a filter medium (20) arranged in zig-zag shaped pleats. On its two longitudinal sides extending in the pleating direction (36), the filter medium (20) is provided with stabilizing strips (34) bonded thereto for stabilizing the zig-zag shaped pleated configuration of the filter medium (20). During use of the filter device (10), the filter element (12) is arranged within a filter element holding frame (14) which is inserted in a holding means, e.g. in the air inlet shaft (18) of an air conditioning system. Due to a certain inherent stability of shape of the filter medium (20) and the stabilizing strips (34), the filter element (12) is sufficiently firm and has a self-supporting construction. The filter element (12) is easy to handle and can be inserted into the filter element holding frame (14) in a simple manner. Except for the actual filter medium (20), the filter element (12) requires little extra material, i.e., for the stabilizing strips (34), in order to ensure stability of the device. Thus, when replacing the filter element (12), the quantity of waste material to be disposed of in addition to the filter medium (20) is extremely small.
Filtre (10) comportant une cartouche filtrante (12) contenant un matériau filtrant (20) plissé en zigzag. Des bandes stabilisatrices (34) sont collées le long des deux parois longitudinales (36) de la cartouche (12) afin de stabiliser la configuration en zigzag du matériau filtrant (20). Pendant l'utilisation du filtre (10), la cartouche filtrante (12) est insérée à l'intérieur d'un cadre porteur (14), lequel est disposé à l'intérieur d'un logement aménagé dans la conduite d'admission d'air (18) d'un système de conditionnement d'air. En raison de la stabilité inhérente à la configuration du matériau filtrant (20) et des bandes stabilisatrices (34), la cartouche filtrante (12) est suffisamment rigide pour être autoporteuse. La cartouche filtrante (12) est de manipulation facile et peut être facilement insérée dans son cadre porteur (14). Hormis le matériau filtrant lui-même (20), la cartouche filtrante ne requiert que peu de remplacement de matériel autre que les bandes stabilisatrices (34). La quantité de matériel autre que le matériau filtrant lui-même (20) qui doit être mis au rebut lors du remplacement de la cartouche filtrante (12) est donc extrêmement minime.
