The cabin air filter in a 2017 Peugeot 408 is located behind the plastic panel near the left leg area of the front passenger seat. Functions of the cabin air filter: 1. Prevents windshield fogging, ensuring clear driver visibility and driving safety; 2. Provides fresh air to the cabin, protecting occupants from inhaling harmful gases while effectively sterilizing and deodorizing; 3. Maintains clean cabin air by preventing bacterial growth, creating a healthy environment. It efficiently filters solid particles like dust, powder, and abrasive particles from the air, while effectively blocking pollen to prevent allergic reactions that could compromise driving safety; 4. Absorbs harmful substances; 5. Filters solid impurities.
I drive a 2017 Peugeot 408 myself, and changing the cabin air filter is quite simple. It's located behind the glove compartment in front of the passenger seat. You need to open the glove box, where there's a plastic cover or panel. Just unscrew two or three small screws or press the clips to remove it, and the filter is hidden inside. If you notice odd smells when using the AC, it's likely the filter is dirty. I replace mine every six months—just buy the right model online, and it takes only a few minutes to do it yourself. This saves a trip to the repair shop and keeps the air fresh. Opt for an activated carbon filter for better odor absorption, and don’t wait until it’s clogged, which could harm the AC system. The maintenance manual also mentions this is an easy spot to service, so no need to overthink it. If you're unsure, watch a video tutorial first—safety comes first.
