Title: Method of establishing baseline filter for air quality

Abstract: A method of establishing a baseline filter for an air quality sensor in a motor vehicle includes the step of providing an air quality sensor for intake air into an occupant compartment of the motor vehicle. The method also includes the step of establishing a moving baseline for a background signal level from the air quality sensor. The method further includes the step of shutting off intake air into an occupant compartment of the motor vehicle when the background signal level exceeds a certain threshold above the moving baseline, thereby preventing undesired gases in the intake air from reaching occupants in the occupant compartment.
