What Does a Cabin Air Filter Do?

Hundreds of pieces and parts work together to keep your vehicle functioning each day. While you may never ever see or notice some of them, others require ongoing maintenance to extend the life of your car. 

The cabin air filter is one of many parts that need a bit of TLC from time to time. Here’s what you should know about the cabin air filter and how frequently to replace it.

What Is a Cabin Air Filter?

The cabin air filter is one of the vital components of your vehicle’s heating and cooling system. It’s the part responsible for removing contaminants from the air that circulates through your car as you drive. 

The contaminants caught by the cabin air filter include dust, pollen, and harmful pollutants. It works just like the air filters in your home to capture particles and remove them from the air before it circulates and gets inhaled. 

How To Find Your Car’s Cabin Air Filter

You can find the cabin air filter located behind the glove box of your vehicle in most cases. It’s a small, pleated filter unit that can be removed and replaced with ease. Simply pull out the old filter and insert the new filter. You’ll be able to see how much dirt, dust, and debris accumulated in the air you breathe!

How Often Should You Replace the Cabin Air Filter?

If you value breathing clean, healthy air, be sure to replace your cabin air filter every 15,000 miles. Your vehicle manufacturer may offer its own guidelines as well. You deserve to breathe clean air, so this isn’t a task you should neglect. 

The area where you live may also influence how often you should replace the cabin air filter in your vehicle. For example, congested urban areas have poorer air quality than remote rural areas, so your filter will fill up faster if you drive through the city frequently. If you live in a desert climate, you may find that dust accumulates in the cabin air filter in a short period of time. 

When in doubt, if you notice any of the following signs, it is definitely time to replace the filter:

  • Musty, unpleasant odors coming through the air in your car
  • A whistling sound from the cabin air intake ducts
  • Reduced or weak airflow
