Why Should You Change Your Cabin Air Filter?

Your vehicle's cabin air filter is responsible for cleaning the air that comes into your cabin through the vehicle's ventilation system. The filter is designed to trap pollen, dust, pet hair and other pollutants, so you don't breathe in dirty air.

When your cabin air filter gets clogged, it prevents clean air from getting inside the cabin. So not only are you not getting clean, filtered air, but and it also limits the airflow for your heating and air conditioning. That means that even if you have your heat turned to full blast, it's blowing dirty air and will take longer to defrost as the fan is not blowing at full capacity.

If you leave your air filter clogged without replacing it for an extended period of time, this can have a negative impact on your ventilation components.

  • Reduces the chance of air leak
  • Lessen wear and tear on HVAC system
  • Allows you to breath in clean air
  • Keeps interior of your vehicle cleaner
