How often should the car's cabin air filter be replaced?
1 Answers
The cabin air filter should generally be replaced every 10,000 to 20,000 kilometers or every 1 to 2 years. Functions of the cabin air filter: It ensures the filter fits tightly against the housing, preventing unfiltered air from entering the cabin. It separates solid impurities such as dust, pollen, and abrasive particles from the air. It adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., with strong and long-lasting moisture absorption. It prevents the car windows from fogging up, ensuring clear visibility for drivers and passengers, thereby enhancing driving safety. It provides fresh air to the cabin, preventing occupants from inhaling harmful gases and ensuring driving safety. It also effectively sterilizes and deodorizes. Precautions for replacing the cabin air filter: Purchase cabin air filters produced by reputable manufacturers. Always turn off the car engine before replacing the cabin air filter. Pay attention to the installation direction of the filter to avoid installing it backwards.
