Abstract
An HVAC system for a motor vehicle includes a filter that absorbs odors and gases in a cabin of the motor vehicle and desorbs the odors and gases when heated, and a heater that is turned on to heat the filter during cool ambient conditions. The heater is turned off during warm ambient conditions and warm ambient air is utilized to heat the filter. The desorbed odors and gases are purged from the cabin of the motor vehicle.
