Your car's air filter catches all the dust and debris before it enters your engine, thus protecting and preserving the life of your vehicle. At an average, you should change your air filter every 15,000 to 30,000 miles. The guide listed below will help you understand the signs your car exhibits when it’s time to do so.


When your air filter is clogged, clean air cannot enter the engine, which affects the emission system of your vehicle. Grime enters your spark plugs, preventing them from sparking, which can cause the death of your engine.

Gas Mileage

Your engine needs ample airflow to work to its highest capacity. When your engine receives dirty air, your car's machinery cannot work at its optimum, resulting in a loss of gas mileage. If you are filling the gas tank more often than usual, it would help to take a peek at the air filter.

Visual Check

A visual check will tell you whether your air filter is clogged up. New or clean filters are either white or off-white. If your air filter is gray, almost bordering on black, or full of particles, it is time to replace it.

Driving Issues

You will know if there is something wrong with your car simply because it does not work the same way. If you encounter difficulties while driving, or if your tailpipe gives off black and dense emission, you may have trouble with your air filter.


If you catch issues with your air filter before it is too late, you can replace it yourself. Check the instruction manual of your vehicle for directions on how to do it. If you ignore the problem for too long, you may have to take your model to a mechanic. Also, waiting to replace your air filter can cause damages to your car, which will run up a longer bill for you.
