What is an air filter? The engine air filter stops airborne contaminants from getting sucked into your vehicles' engine such as dust, leaves, and debris before it can do damage to the engine. Replacing your vehicle's air filter regularly can have a significant impact on your vehicle's engine life and performance as well as help to keep your cabin air cleaner.
Signs you may need your Air Filter changed:
Loss of engine power or fuel economy
Increased noise when fan is running
Odd, damp, or musty smell when vent is on
Visually dirty or clogged air filter
Engine Air Filter
That's the filter that captures and cleans the airborne contamanants such as dirt and dust before they can enter the engine. People wonder how often they should change their engine air filter. Manufacturers recommend replacement at particular intervals, which may be shorter if your vehicle is subject to severe conditions.
Cabin Air Filter
The cabin air filter cleans out dust, pollen, spores and other pollutants. It helps improve the interior air quality that you and your passengers breathe. Not all vehicles are equipped with a cabin air filter.
