The air recirculation button in your car helps improve comfort and air quality by reusing the air inside the cabin instead of pulling in outside air. This makes cooling more efficient on hot days and keeps out pollution, exhaust fumes, and allergens—especially useful in traffic or poor air conditions.
However, it’s best to turn it off in cold weather or when windows fog up, as fresh air helps reduce moisture and maintain clear visibility. Knowing when to use recirculation can make your drive more comfortable and safer.
