ABSTRACT:
The invention provides a method and device for detecting the state of an air filter in a ventilation system of the passenger compartment of an automobile vehicle. The installation is put into operation in a given mode and a parameter of an air flow emitted into the passenger compartment by an air nozzle of the installation is measured by means of a measurement device filled with a collector. The measured value of the parameter is then compared with a reference value, to determine whether or not the filter needs to be replaced.
