How many air conditioning filters does a vehicle have?

[VanessaLee]

Generally, a car has only one air conditioning filter, while some high-end models may have two. The air conditioning filter is typically installed inside the glove compartment on the passenger side, and it can be seen by opening the glove box. Functions of the air conditioning filter: 1. It ensures the filter fits tightly against the housing, preventing unfiltered air from entering the cabin; 2. It separates solid impurities such as dust, pollen, and abrasive particles from the air; 3. It adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2 in the air, with strong and long-lasting moisture adsorption capabilities; 4. It prevents the car windows from fogging up, ensuring clear visibility for the driver and safe driving; 5. It provides fresh air to the passenger compartment, preventing occupants from inhaling harmful gases and ensuring driving safety; 6. It effectively sterilizes and deodorizes.
