What is the installation direction of the air conditioning filter?

[DiNolan]

The installation direction of the air conditioning filter is to have the side with two clips facing outward and the side with three clips facing inward. The function of the air conditioning filter is to block and absorb various harmful substances in the air, reducing allergic irritation to passengers inside the vehicle. If the air conditioning filter is not replaced regularly, bacteria can easily breed and be discharged into the car interior through the ducts, which is harmful to human health. The replacement cycle of the car air conditioning filter depends on individual driving conditions, external environment, and seasonal climate. Generally, for urban household cars, it should be replaced every 10,000 to 20,000 kilometers or about once a year. If the driving environment is poor with more dust, the air conditioning filter tends to get dirty faster, and the replacement cycle should be appropriately shortened. Additionally, the frequency of air conditioning use varies in different seasons, so the replacement cycle also differs. In summer and autumn, when air conditioning is used less frequently, the replacement cycle can be slightly longer.
