A method of monitoring the service life of a filter () in a filter system equipped with a fan, in particular a filter () in an air conditioning system of a motor vehicle, the instantaneous air speed () preferably being measured on each startup of the system using a sensor () downstream from the filter (), compared to the reference air speed (R) from the unloaded filter (), 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 ().

Method and device for monitoring the service life of a filter

A filter system, including a folded filter ( ) and a cover ( ) of a filter housing ( ), the folded filter ( ) and the cover ( ) forming a preassemblable unit ( ) and being essentially sealingly joined to each other so as to be detachable without destruction.
