What is the correct installation direction for a car's cabin air filter?
1 Answers
The installation direction of a car's cabin air filter is usually indicated on the filter itself. There is typically a small arrow on the side of the filter, and the direction of the arrow represents the direction of airflow, which is usually from the front of the car toward the rear. Some cabin air filters may have the letters "UP" next to the side arrow, indicating that the filter should be installed with that side facing upward. Due to differences in brands and models, the markings on cabin air filters may vary. A car's cabin air filter is installed in the air conditioning system and serves to absorb dust particles, reduce respiratory discomfort, minimize irritation for allergy sufferers, and protect the air conditioning cooling system.
