The term "air filter", in the automotive world, refers to a two-part system. The first filter the air that goes into your engine. The cabin air filter is the second and one that fewer drivers consider. The cabin air filter filters the air that you and your passengers breath. It's a quick and easy task to replace the cabin air filters. Many (but not all!) newer vehicles have a cabin filter. You can find out by checking your owner's guide.

What Is a Cabin Filter?

Cabin air filters, or passenger compartment air filters, are located in the HVAC system of your vehicle. Its main function is to remove pollutants like dust, pollen and other allergens from the air entering the passenger compartment or cabin.

Clean cabin air filters improve the air quality in the vehicle, and the driving experience. A dirty or clogged air filter can also reduce the efficiency and effectiveness of the HVAC system, as well as cause unpleasant odors. It is therefore important to replace the air filter regularly, according to the manufacturer's recommendations.
