How does the Audi A8 measure and adjust for air quality?

I've heard that the Audi A8 has the ability to sense and improve air quality within the vehicle, can you explain how this works and what benefits it provides?

Yes, the Audi A8 is equipped with an air quality sensor that measures the level of pollutants in the outside air and automatically closes the air vents to prevent them from entering the vehicle. This allows for a cleaner and healthier driving experience.
