CABIN AIR FILTER

What is it?
A filter used to clean incoming air for the car's HVAC system. Introduced in European vehicles, cabin air filters are now becoming common on more domestic and Asian makes and models. Some examples include the Ford Taurus, Contour, Windstar and Ford trucks; the Chevrolet Impala, Monte Carlo, Suburban, Tahoe and Silverado; and the Lincoln Navigator. Japanese cars such as the Honda Accord and Odyssey, and the Acura RL and TL use cabin filters. To date, approximately 40% of cars have cabin air filters, but the number grows each year.

What does it do?
The cabin air filter helps trap pollen, bacteria, dust, and exhaust gases that may find their way into a vehicle's ventilation system, making the interior of the car a healthier place.

Maintenance Tips/Suggestions
Cabin air filters should be replaced according to owners' manual guidelines, usually every 15,000 miles. It's not uncommon, however, for cabin air filter replacement to be overlooked in the owner's manual. Do not try to clean this filter and reinstall it. For best results, consult filter manufacturer application charts to see if your car is listed. 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. Some filters require basic hand tools to remove and install the filter; others just require your hands. If neglected, a restricted cabin air filter can impair airflow in the HVAC system, possibly causing interior heating and cooling problems.
