The Wall Street Journal points out that using recirculation can boost fuel efficiency. Since it’s easier to cool air that’s already cool, it saves fuel and gives the AC system a break, maybe even making it last longer.

Air quality matters, especially in smoggy cities. The air recirculation button is like a shield against bad stuff. By using the recirculation mode, drivers can dodge outside pollutants, breathing easier and keeping the cabin nice.

The perks go beyond clean air. Recirculating air can quiet things down by blocking street noise. And with less work for the AC, the car parts stress less, which could mean fewer trips to the mechanic and better long-term performance.
