Most of you know about oil, fuel, and air filters, but you may not be aware of a fourth filter in your vehicle that's responsible for cleaning the air you breathe - the cabin air filter.

Suffer from allergies?  Then a quality cabin air filter is an essential feature.  The cabin air filter prevents dust, pollen and other contaminants from entering the passenger compartment.  Many have the ability to trap odors, an additional advantage.

The cabin air filter also provides protection for the air conditioning evaporator inside the vehicle's HVAC system.  This environment is perfect for mold and mildew growth.  An accumulation of mold and mildew can produce unpleasant odors and the formation of irritating and toxic spores.

Besides the health benefits of changing your cabin air filter, there are performance benefits as well.  A plugged cabin air filter can restrict airflow through the heater, defroster, and air conditioner.

Cabin air filters typically have a service life of two to three years, or 20,000 to 30,000 miles, but actual service life will depend on driving conditions.  Odor-absorbing cabin air filters with activated charcoal are good for about 12 to 14 months, or 15,000 miles, so annual replacement is recommended.
