Disclosed are air circulation systems for vehicle heating and cooling system, especially for heating and cooling the passenger compartment and other pertinent compartments of motor vehicles, as well as trains, airplanes, etc. The invention more particularly concerns apparati and methods for improving the air quality in such systems through the use of filters for decontamination of air flows. The invention relates generally to apparati and methods for causing the air flow to pass through a decontamination module to clean the air. Preferred devices of the present invention controls the extent of such cleaning by a by-pass and damper arrangement, which apportions the flow between the module and the by-pass. Various bypass configurations having various flow characteristics are disclosed. The invention has application to both new vehicles as original equipment and older vehicles as added equipment.
