What type of cabin air filter does the 2005 ford freestyle use?

The 2005 Ford Freestyle does not come equipped with a cabin filter for the vehicle. Cars that don't come with a cabin filter will usually have a mesh or other type of covering that will prevent leaves and other debris or foreign objects from entering the A/C system. In cars without a cabin filter they will have an evaporator that will act like a filter to help keep pollen and other particles out of the air that is flowing into the car. The car does not have a cabin filter so You may need to check the A/C system around the vents at the top of the dashboard and outside near the firewall to make sure there is not debris blocking the system which can happen periodically.
