Peugeot's air conditioning filter is located under the front windshield of the car. The functions of the car air conditioning filter are: 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 grinding 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 capabilities. 4. 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 effectively sterilizes and deodorizes.

I've been driving a Peugeot for many years, and the most common location for the cabin air filter is behind the glove compartment on the passenger side. Specifically, when you open the glove box, you'll find several screws or clips at the bottom or on the sides. After removing them, the filter cover will be exposed. The replacement process isn't difficult—just unscrew the screws with a screwdriver, take out the old filter, and when installing the new one, make sure the arrow points outward. I change it regularly myself, once a year or every 20,000 kilometers, which helps maintain fresh air inside the car and prevents dust buildup that can cause odors. Beginners are advised to check the owner's manual or online tutorials, and be careful not to damage plastic parts during the process—just a simple screwdriver is needed. After replacement, remember to test the AC airflow to see if there's any improvement. Regular maintenance of this part can also save money by reducing trips to the repair shop.

As a professional frequently working with Peugeot vehicles, the cabin air filter is typically located behind the glove compartment, requiring removal of the glove box bottom components for access. The replacement process involves removing screws or clips, extracting the old filter, ensuring the new filter matches the correct model number and is properly installed. I recommend checking it every six months, or following the maintenance schedule in the owner's manual. Strong odors or reduced airflow indicate replacement is needed. Using high-quality filters improves filtration efficiency and prevents bacterial growth that could impact health. During actual operation, remember to reset the AC system and test for even airflow distribution. Regular replacement is a low-cost, high-return habit that enhances driving comfort.
