If you have a traditional car that uses gasoline and you park in a garage attached to your home, there is one thing you should do to keep the air clean in your home: Minimize how long your car runs inside your garage. Even with the garage door open, running your car for just a minute can build up dangerous levels of carbon monoxide. And when you leave and close the door, that buildup can stay in your garage for hours. Instead, open the garage door, start the car and leave as quickly as possible.
