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.

As a long-time car enthusiast, I've studied the air conditioning system design of the 2017 Peugeot 408. Its filter is located behind the glove compartment on the passenger side, requiring the glove box cover to be removed to access the installation slot - a fairly common layout. Peugeot makes good use of space in this model, so replacing the filter isn't particularly difficult. Generally, it's recommended to check or replace it every 10,000-20,000 kilometers or every other year. The filter model matches the original vehicle design, and domestic brand replacements work just fine. If you notice stuffy air or unpleasant odors when using the AC, address it promptly to avoid health impacts. By the way, there are plenty of DIY tutorials shared by fellow owners - just search forums for illustrated guides. If you're not confident in your mechanical skills, any quick-service shop can handle it in about ten minutes at a reasonable and reassuring price.

I just started driving when I encountered an air conditioning issue, and later learned that the 2017 Peugeot 408's cabin air filter is located inside the glove compartment on the passenger side, behind which is a small housing for the filter. Open the glove box and pull out the cover to see it—no tools required. New drivers shouldn't worry; just refer to the owner's manual with its diagrams and follow the steps. If you really can't figure it out, I recommend visiting a 4S shop—the technician can get it done in two minutes and will also perform a free system check. Follow the manual's replacement cycle, roughly once a year, ideally when the weather warms up, to ensure fresh cabin air and safe driving.
