Where is the air conditioning filter located in the new Peugeot 308?

The air conditioning filter of the all-new Peugeot 308 is located under the left side of the front passenger seat. Here is some relevant information: 1. The maintenance cycle of the air conditioning filter is not fixed and mainly depends on the usage environment. Sometimes, when you notice odors or mold inside the car, it is a sign that the filter needs to be replaced. The air conditioning filter tends to accumulate a lot of dust, so use compressed air to blow away the dust. Never rinse it with water, as this will quickly render it unusable. When the filtering function of the activated carbon inside the air conditioning filter decreases, replace the filter at a 4S shop. 2. The air conditioning filter must be correctly installed in its position. Using the air conditioning without the filter in place may degrade its dustproof performance and affect the air conditioning's efficiency. In cities with poor air quality, it is recommended that car owners replace the air conditioning filter twice a year to ensure good health.
Last time I helped my neighbor fix his Peugeot 308, the cabin air filter was quite well hidden. It's behind a panel in the glove compartment on the passenger side, and you have to crouch down to see it. First, empty the passenger footwell, then you'll see a plastic panel with clips. Use some finesse to pop the clips open and you'll find the white filter slot. However, the 308's design is a bit tricky—you have to tilt your head and reach in awkwardly, and I ended up scratching two spots with my nails. I recommend preparing a short-handled screwdriver to pry the clips and wearing gloves to prevent scratches. The filter has a front and back side; the arrow should point toward the front of the car. Installing it backward affects filtration. Older models require vertical insertion, while newer ones use a horizontal slide-in—don’t force it the wrong way.
As a car mechanic with ten years of experience, I remember the filter location of the Peugeot 308 very clearly. In the new model, it's positioned near the left foot area of the front passenger seat, requiring the removal of three Torx screws and a plastic cover. After unscrewing with a T20 screwdriver, the cover can be slid toward the driver's side to remove it. The filter is a square piece with activated carbon, measuring approximately 20×18 cm. Two important reminders: First, always disconnect the negative terminal of the battery before replacement to avoid triggering error codes. Second, French cars have brittle plastic parts, so be careful not to break the clips when operating in cold winter conditions. At a repair shop, replacing an original filter costs around 300 RMB including labor and parts, but you can buy a Mann filter for about 50 RMB and do it yourself.
Last month, I just replaced the cabin air filter for my 2023 Peugeot 308, and its location is indeed tricky to find. There's a long cover panel on the left side of the passenger footwell with six clips. First, use a pry tool to lift it from the bottom, then push it toward the rear of the car to remove it. The filter compartment is inserted at an angle, so be careful not to let leaves or dust fall into the air duct when removing the old filter. The Mahle LAK748 I bought fits perfectly, and the arrow should point toward the seat. The whole process takes about ten minutes, but the hunched-over posture can be tough on the back. It's recommended to replace it every 20,000 kilometers or once a year. Given Beijing's air quality, the filter turns completely black in just six months.
