A method for operating a cabin air filtration system (12) with an air filter device (20) for filtering an air flow (38) into the cabin (14), which air flow is composed of fresh air from outside and recirculated air from inside the cabin (14), wherein a magnitude of the air flow through the air filter device is adjustable, wherein a recirculation ratio of fresh air and recirculated air of the air flow through the air filter device is adjustable, and wherein a total influx (22) of air from outside is enterable into the cabin as a filtered influx (26) through the air filter device (20) and as an unfiltered infiltration influx (28) bypassing the air filter device. The method comprises the stepsA) providing system information which links- at least one characteristic of the air filter device comprising information on a global filtration efficiency for the total influx of air from outside into the cabin,- the magnitude of the air flow through the air filter device,- a vehicle speed, and- the recirculation ratio of fresh and recirculated air;B) providing a required vehicle filtration efficiency;C) determining from the system information for the current vehicle speed and the current magnitude of the air flow a recirculation ratio of fresh and recirculated air, such that the global filtration efficiency corresponds to the required vehicle filtration efficiency provided in step B), and operating the cabin air filtration system at this recirculation ratio.
