What Happens If the Cabin Air Filter Is Installed Backwards?
1 Answers
Installing the cabin air filter backwards will affect its filtration efficiency and may reduce the airflow from the air conditioning system. Additional information about cabin air filters is as follows: 1. Cabin air filters have a specific orientation and must be installed correctly, with the front side facing the airflow direction. The airflow inside the car typically blows from bottom to top. Generally, there is an arrow indicator on the filter, with the arrow pointing in the direction of airflow, which is also the correct installation direction. 2. The two surfaces of the cabin air filter have different structures. The ordinary fuzzy side is the front side, facing upwards towards the airflow direction, while the side with supporting wire structures is the back side, facing away from the airflow. For filters containing activated carbon, the black side should face the airflow direction (front side), and the white side should face away from the airflow (back side).
