Where is the cabin air filter installed?

[McEmmanuel]

Automotive cabin air filters are primarily installed in two locations: one is behind the glove compartment on the passenger side, and the other is on the lower right side of the windshield. The functions of the cabin air filter are as follows: 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, etc., from the air, with strong and long-lasting moisture adsorption. 4. It prevents 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. 5. It maintains clean air in the cabin, preventing bacterial growth and creating a healthy environment. It effectively separates solid impurities such as dust, core powder, and abrasive particles from the air. It efficiently intercepts pollen, ensuring that drivers and passengers do not experience allergic reactions that could affect driving safety.
