    摘要: A method of monitoring the service life of a filter (1) in a filter system equipped with a fan, in particular a filter (1) in an air conditioning system of a motor vehicle, the instantaneous air speed (21) preferably being measured on each startup of the system using a sensor (2, 20) downstream from the filter (1), compared to the reference air speed (R) from the unloaded filter (1), and transmitted to a service computer and/or indicated on a display, and the need to replace the filter being signaled when this value falls below a predetermined threshold or threshold range of the instantaneous air flow rate (21).

    摘要: A filter cartridge made of an accordion fold pack folded in a zigzag-shaped manner and made of a thermoplastically moldable and heat-sealable material, whose folds are held at an adjusted, defined distance relative to each other, in particular made of a nonwoven fabric. The longitudinal direction of the accordion fold pack, transversely to the folds, the individual fold peaks are folded over in the same direction in at least one strip on one or both sides of the accordion fold pack and in each case fixedly joined to the next following, likewise turned-down fold at least in the overlapping region, by heat-sealing.
