🔁 What Is the Air Recirculation Button? (Demystified)
That circular arrow symbol isn’t just decoration. It controls a small flap inside your HVAC system that decides:
“Do I pull in fresh air from outside… or reuse the air already inside the cabin?”
🌬️ Fresh Air Mode (Button OFF – Default)
- Draws air from outside through vents near the base of your windshield
- Passes it through the cabin air filter
- Then heats or cools it before blowing into the cabin
- Best for: General driving, air quality, and preventing stuffiness
🔄 Recirculation Mode (Button ON)
- Closes the outside air intake
- Recycles the same air inside your car through the system
- Best for: Rapid cooling, blocking outside pollutants, or reducing allergens
💡 Key fact: Recirculation does not “clean” the air—it just reuses it. If your cabin air filter is dirty, you’re just blowing the same dust around!
