Does the car's air conditioning filter need to be replaced during maintenance?

It doesn't need to be replaced every time; it mainly depends on the frequency of using the external circulation. Generally, it should be checked every time the engine oil is changed. Functions of the air conditioning 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., from the air, with strong and long-lasting moisture adsorption. It prevents the car windows from fogging up, ensuring clear visibility for drivers and passengers and safe driving. It provides fresh air to the cabin, preventing occupants from inhaling harmful gases and ensuring driving safety. It also has strong antibacterial and deodorizing effects. Cleaning the air conditioning filter: The filter is prone to accumulating a lot of dust. Simply blow away the loose dust with compressed air or similar methods. Never wash it with water, as this can easily damage it. Over time, the activated carbon filtration function in the air conditioning filter will diminish, so it's recommended to replace the filter at a 4S shop.
