Fewer odors and improved air quality are just two of the benefits of replacing your cabin air filter regularly. Mold can build up on the filter if it is not changed, which can cause bad odors and unhealthy air. But by replacing your cabin air filter once a year or every 12,000 miles, you can avoid breathing in that unhealthy mold and keep your cabin smelling fresh. If you are driving in heavily polluted areas or traveling on dirt roads, you should change your cabin air filter every 5,000 miles.

A vehicle's cabin air filter helps remove harmful contaminants, such as pollen and dust, from the air you breathe inside the car.

If you notice that your car has an unpleasant odor or that airflow has decreased, consider replacing the cabin filter to give the system and yourself a breath of fresh air. If left untreated, a dirty filter can clog, limit the amount of clean air entering the cabin, and cause the heating or air conditioning to work harder than necessary. Specifically, your car's cabin air filter is made to prevent allergens, dust and external contaminants from entering the ventilation grilles, thus keeping the air you breathe clean.
By replacing your cabin air filter once a year or every 12,000 miles, you can breathe easy every time you get in the car.

Cabin filters began appearing in cars in 2002 and more than 80% of all vehicles in circulation today come with a factory-equipped cabin air filter. Poor efficiency can cause other problems, such as loss of air volume, bad odors in the cabin, or premature failure of HVAC components.
