Do you have a musty odor in your vehicle? Do you have allergies? Is your vehicle exposed to a large amount of road dust? Try changing your cabin air filter for cleaner air inside the passenger cabin. Manufacturers recommend every 12 months or 12, 000 miles. In areas with higher pollutants in the air, you may wish to change the cabin filter twice a year. This Cabin Air Filter has carbon-impregnated media to help neutralize odors and keep your car's interior air smelling fresh.
