Abstract

An air filter device for a motor vehicle is provided with a filter housing having an air inlet and an air outlet, a filter insert which is received in the filter housing and divides the inside of the filter housing into an untreated air section and a pure air section, and a bypass line for supplying air into the untreated air section. The bypass line extends from a connection opening in the filter housing to a cooler, especially a charge air cooler of the motor vehicle.
