How Often Should You Replace Your Cabin Air Filter?

There are many systems and parts to maintain on a vehicle, so it is no surprise that many may be forgotten. However, that doesn't make them any less important. The cabin air filter is a vital part of your vehicle's ventilation system. Its job is to remove pollutants from the air which circulates through your car. Clean air within the cabin is essential for the health and safety of all passengers. Without a proper air filter, you could be at risk of harmful engine gasses entering the cabin. Not only do you need to worry about your vehicle's gases, but also the trucks and other vehicles which leave gasses behind as they drive in front of you.

If you struggle with allergies, a good cabin filter is critical as it helps remove the pollen from the air as you drive. Another benefit of clean cabin air filters is lower maintenance costs. Dirty and polluted air will cause your vehicle's ventilation system to work harder, and in turn, reduce its efficiency. If ignored for too long, a dirty filter can eventually lead to a motor burnout within your vehicle's ventilation system, causing your entire air conditioning system to stop working.


The industry standard is to replace the cabin air filters once every 30,000 miles; however, it is best to consult your owner's manual or a professional for an exact timeframe.


A few warning signs which may indicate a need for new cabin air filters include:

  • A musty odor within the cabin
  • Vents that blow with considerably less force than normal
  • Foggy or icy windows which take much longer to clear
  • A whistling noise coming from your air vents
  • Allergy symptoms increase during long vehicle rides
