Activated carbon cabin air filters do have a front and back side. Here is the relevant information: 1. The orientation of the activated carbon cabin air filter is determined by the blower. The filter is installed inside the glove compartment. Turn on the AC and observe the blower's airflow direction: If the air blows upward, the black activated carbon side should face downward; if the air blows downward, the black activated carbon side should face upward. The black side is the intake side, while the white HEPA cotton side is the outlet side. 2. As the name suggests, a dual-effect activated carbon cabin air filter combines the ability to filter dust with the activated carbon's capability to adsorb harmful gases. The dual-effect structure consists of two parts: filter fabric + activated carbon.
