Your Vehicle’s Air Filters Need Changing

Every vehicle has a couple of air filters, one in the engine compartment and one in the passenger cabin. Read on to learn what they do and how often they should be changed.

Engine Air Filter

The engine air filter is located under the hood. Your engine has an air intake system to provide a balanced air and fuel mixture for the combustion process. And the quality of the air entering your engine is equally important as the fuel coming in. That is why your engine air filter is put in place to keep out the dust, dirt, debris, bugs, and other contaminants that can harm your engine parts. 

How Often Should the Engine Air Filter Be Replaced?

In short, you should simply exchange it when it looks dirty. If it gets too full or clogged, your engine may not get enough airflow. Moreover, your engine may be at risk of more wear and tear. The frequency of your air filter change can vary depending on the air quality of the environment you drive in. Most professional mechanics will recommend a replacement every 15,000-30,000 miles.

Cabin Air Filter

The cabin air filter is different from the engine air filter. It ensures clean air quality inside the passenger cabin. It can keep out pollutants, pollen, allergens, dust, and more. If you want the air you breathe inside your car to be clean, keep your cabin air filter in tip-top shape. 

How Often Should the Cabin Air Filter Be Replaced?

You should swap the cabin air filter out when it looks dirty. Another sign that may indicate it needs replacing is if the air blowing through your vents is smelly. On average, cabin air filters should be changed every 30,000 - 50,000 miles.
