For people sensitive to pollen or airborne particles, this feature can provide relief by limiting outside air exposure. However, it works best when the cabin air filter is clean and well maintained.
Despite its benefits, recirculation should not be used constantly. In humid or rainy conditions, it can trap moisture inside the car, causing windows to fog and reducing visibility.
For longer drives, switching between fresh air and recirculation is the best approach. This keeps the cabin comfortable while maintaining good air quality throughout your journey.
