Project Description

Automatic Transmission Service

New cars are increasingly equipped with cabin air filters that remove particulates, and sometimes odors, from the air that enters the vehicle through the heating, ventilation, and air conditioning (HVAC) system. Cabin air filters are usually standard equipment on premium models, while other cars make them available as a stand-alone option or part of an option package. Some cars have two or more cabin air filters.

Filter Replacement

There are three factors to consider when determining if your car’s cabin filter needs to be replaced:

  • Mileage: Factory recommended intervals for replacing cabin air filters range from 15,000 to 30,000 miles. Ask your auto repair shop or check your auto’s owner’s manual for exact mileage specifications.

  • Levels of fine particulate matter: You may need to replace the filter more frequently if you drive in an area that has higher than normal levels of dust, pollen, and other airborne debris. Many motorists are shocked when they see how many contaminants cover the surface of a cabin air filter that has been in service for an extended time.

  • Performance: Symptoms of a restricted cabin air filter include reduced airflow through the HVAC system, windows that fog up easily and are hard to defrost, and persistent bad odors. A restricted cabin air filter also places a greater load on the ventilation fan and can shorten its service life.

Cabin air filters are located in the ductwork that delivers outside air to the HVAC system. In some cars, the filter is in the engine compartment near the base of the windshield. In others, it is located under the dash or behind the glove box.
