How often should the car air conditioning filter be cleaned?

[McBriella]

Car air conditioning filters should be cleaned approximately every 10,000 kilometers. Other situations that require cleaning include: 1. A significant reduction in airflow from the air conditioner; 2. Frequent driving on dusty roads. The cleaning method for the air conditioning filter is as follows: 1. Open the indoor unit cover of the air conditioner and remove the filter; 2. Use a brush to remove dirt and soak it for 10 to 20 minutes; 3. After soaking, brush the filter to ensure there are no blockages; 4. Dry it with a dry cloth and reinstall it. The functions of the car air conditioning filter are: 1. To ensure the filter fits tightly against the housing, preventing unfiltered air from entering the cabin; 2. To separate dust, pollen, and abrasive particles from the air; 3. To absorb moisture, soot, ozone, odors, carbon oxides, sulfur dioxide, and carbon dioxide from the air.
