But don't drive like this for too long. Recirculation runs the incabin back through the system repeatedly instead of outside air. As it does this, it removes some of the oxygen from the air. After a long period of time, you'll be breathing reduced oxygen air. People have passed out driving like this for extended periods. Most manuals advise against keeping recirc on longer than necessary to either heat or cool the cabin.
