The Importance of Changing Your Car’s Air Filter

A clean engine runs more efficiently than a dirty engine and your car’s air filter is the engine’s first line of defense. A new air filter allows your vehicle’s engine to get clean air, a key component in the combustion process. The air filter prevents airborne contaminants such as dirt, dust and leaves from getting pulled into your vehicle’s engine and potentially damaging it.

How often should I replace my air filter?

Vehicle manufacturers recommend changing a vehicle’s air filter every 15,000 to 30,000 miles. Check your owner’s manual for the specific mileage for your vehicle. You can also consult your local mechanic for a recommendation based on your driving habits. 

Driving conditions and climate will also affect the lifespan of an air filter. If you often drive on dirt roads, do a lot of stop and start driving, or live in a dusty and dry climate, you will need to change your air filter more often.  Doing a periodic visual inspection will help determine when to replace it.

How do I perform a visual inspection of my air filter?

Even individuals with little mechanical experience can visually inspect an air filter. Refer to your owner’s manual for the location of the air filter. It is typically housed under a cover that is easily opened by removing the snaps or clips. Once you have the cover off, pull the air filter out and hold it up to the light.


Checking to see if your vehicle’s air filter needs changed is not difficult.

If the air filter appears clean and white or just slightly dirty, then it doesn’t need to be changed. If you observe a thin layer of dirt, you can clean the filter by tapping it to remove loose dirt. If your engine air filter is caked with dirt, it is time for a replacement.
