What Is A Cabin Air Filter And Why Is It Important?

A cabin filter is a pleated fabric panel that is part of the HVAC (Heating, Ventilation, Air Conditioning) system. It is not the same as an air filter that filters the air going into the engine. The cabin filter cleans the air going into the HVAC system. It removes dirt, pollutants, and pollen.

If it clogs up, the air inside the car will become polluted. It will also limit the efficiency of the HVAC system. Forcing it to work harder to push air into the cabin. This extra strain can eventually damage the blower fan.

When Should You Replace Your Cabin Air Filter?

Every manufacturer has a different recommendation. Some suggest a change at every oil change, while others want you to change the filter at a specific mileage.

A good rule of thumb is to replace your cabin filter once a year or every 15,000 miles. If you spend a lot of time in your car or live in an area with lots of pollen, you may want to do it even more often. These are the signs that your cabin filter needs replacing:

  • The HVAC system blows weak
  • Occupants get hay fever symptoms
  • The windshield fogs up easily
  • The air coming through the vents smells stale

Are OEM Cabin Air Filters Better Than Aftermarket?

Cabin filters may look simple, but they are made of a complex mix of synthetic fibers and fabrics. An aftermarket cabin filter may look good, but there is no telling how it has been made.

Only genuine OEM cabin filters are made to manufacturer specifications. They are guaranteed to be the perfect size and shape. They also come with Ford’s replacement part warranty. Aftermarket filters don’t.
