If you get headaches, allergic reactions or breathing problems riding in your car, it’s probably time to change the cabin air filter. Cabin air filters clean the incoming air and remove allergens, and should be replaced every 12,000 to 15,000 miles, or per the owner’s manual, according to the Car Care Council.
More than 80 percent of new domestic and import vehicles sold in the U.S. today come equipped with cabin air filtration systems or a slot where one can be installed.
