The air is filled with pollen, dust, and pollutants that are drawn inside vehicles through air conditioning and ventilation systems
Cabin air filters clean the incoming air, removing allergens, and should be replaced regularly, says the Car Care Council
"A dirty or clogged cabin air filter can cause contaminants to become so concentrated in the cabin that passengers actually breathe in more fumes and particles when riding in the car than walking down the street," said Rich White, executive director, Car Care Council. "With allergy season here, replacing the cabin air filter is a simple way for you and your passengers to breathe easier while driving."
A restricted cabin air filter can cause musty odors in the vehicle and impair airflow in the HVAC system, possibly causing heating and cooling problems. Over time the heater and air conditioner may also become damaged by corrosion. In addition to trapping pollen, bacteria, dust, and exhaust gases, the cabin air filter prevents leaves, bugs, and other debris from entering the heating, ventilating, and air-conditioning (HVAC) system.
Cabin air filters should not be cleaned and reinstalled. Instead, they should be replaced every 12,000 to 15,000 miles, or per the owner's manual. Most filters are accessible through an access panel in the HVAC housing, which may be under the hood or in the interior of the car.
Our automotive service technicians can help locate the cabin filter and replace it according to the vehicle's owner manual.
