Where is the cabin air filter installed?
2 Answers
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.
I've noticed that the car's cabin air filter is often hidden behind the glove compartment on the passenger side. I've changed it myself several times in my car. You need to open the glove box, and usually there are some small clips or screws to remove before you can access the filter housing. This concealed design is meant to protect the filter from engine heat. Replacing it is actually quite simple, with many online video tutorials showing how to do it. I recommend changing it every 10,000+ kilometers—don't skip this, as the filter traps dust and pollen to keep the cabin air fresh and prevent allergies. If you're unsure about the exact location, checking the owner's manual is the most reliable approach. While the position varies slightly between models like SUVs and sedans, the general setup is similar. Long neglect can lead to reduced airflow or unpleasant odors, compromising comfort.
