A catalyst mass is traversed by the air heated by the heater and disposed downstream of the heater for further purifying the air, with further device downstream of the catalyst mass for cooling the air upon passage thereof through the catalyst mass, all of the devices collectively forming an air purifier to a passenger compartment of an automobile for supplying the compartment with purified air.
