Driving with Your Windows Down Lets in 80% More Pollution

Do you crank your car’s A/C when it’s hot out, or roll down your windows?

A new study found A/C might be the better option when it comes to your health.

Researchers in England looked at how much pollution we’re exposed to in our cars. And it’s up to 80% more when you have your windows down.

Your A/C isn’t perfect either. It only filters out larger particles, and smaller ones still get in. But sitting in traffic with your windows open is worse.

The best thing to do is hit the button that makes the air inside your car recirculate. It’s usually an outline of a car with a curved arrow inside it.

And the most important time to do it is on your morning commute, because that’s when the most cars are on the road.
