Another advantage of recirculation mode is improved efficiency and comfort. Since the system is adjusting air that is already closer to the desired temperature, it reduces strain on the air conditioning or heating system. It can also be helpful in situations where outside air quality is poor, such as heavy traffic, dusty roads, or areas with strong smells. People who are sensitive to pollen or pollution may also benefit, as fewer outside particles enter the cabin. When used at the right moments, this feature can noticeably improve the driving experience for both drivers and passengers.
