Ensuring the proper orientation of the cabin air filter is essential for its optimal performance in trapping contaminants and keeping your car's interior fresh and healthy. To change the airflow direction of your cabin air filter, ensure the arrow (or "UP" marking) on the filter is pointing toward the car's interior during installation.. I'm changing the cabin filter for the first time and the new filter does not have an UP Arrow, it has an air flow arrow, so my question is ; which way should the air flow be? Thanks
