Open the engine hood, the cabin air filter is located inside the air intake in front of the front passenger seat. There are three clips on the air intake cover. Push the clips toward the windshield to remove the air intake cover, or you can use a screwdriver to pry open the cover. Once opened, you will see the cabin air filter. Here is more information about the cabin air filter: 1. When a car inhales outside air while driving, the presence of a cabin air filter can isolate various particles in the air, including dust, pollen, etc. Without a cabin air filter, these particles entering the cabin can contaminate the car's air conditioning system, leading to a decline in the performance of the cooling system. Moreover, inhaling these particles may cause allergic reactions in humans. 2. There are two types of cabin air filters used in cars: one without activated carbon and one with activated carbon. The cabin air filter with activated carbon can also absorb a large amount of odors. The replacement cycle for the cabin air filter is generally every 10,000 kilometers. The cabin air filter cannot be cleaned with water.

I remember my experience of replacing the air conditioning filter for the 2008 last year. It's located behind the glove compartment on the passenger side, and you have to remove the entire glove box to access it. First, press the left and right sides of the glove compartment inward until you hear a click, then you can remove it. Behind it, you'll see a rectangular cover plate. Pry open the cover plate, and you'll find the white filter wedged in the slot. It's best to wear gloves when doing this; last time, my fingernail almost got scratched by the plastic clip. I recommend replacing it every six months, especially in northern areas where willow catkins are abundant in spring. Last time I pulled out my filter, it was full of dust and leaves—no wonder the air conditioning had a musty smell.

Last time during the at the 4S shop, I watched the technician replace the Peugeot 2008's cabin air filter. The location is quite hidden, tucked behind the glove compartment on the passenger side. You need to press both sides of the glove box and gently pull outward to release the clips. After removing the glove box, there's a plastic cover behind it; you have to push it aside to access the filter compartment. It might be a bit tricky for first-timers since the plastic parts fit tightly. I recommend doing this in a well-lit area—the first time I did it, I missed installing one clip, resulting in the glove box not closing properly. The filter must be inserted vertically and not upside down; the arrow direction should align with the airflow.

The 2008's cabin air filter is located on the passenger side. When you sit in the passenger seat and look down at the glove box, press the clips on both sides of the glove box to remove it. Behind it, there's a mesh panel—lift this panel to reveal the rectangular slot where the filter is installed. This design doesn't require tools but does test your hand strength. Last time I replaced it, I found the old filter was full of tree seeds, probably from parking under a tree. Doing it yourself can save you around a hundred bucks, and buying a PM2.5 filter online costs just over thirty.

The location of the 2008's cabin air filter is quite user-friendly, situated just behind the glove compartment on the passenger side. If you're replacing it yourself, remember three points: the glove box has flexible clips—don't force it open; after sliding open the cover, the filter must be inserted vertically; and always check the directional arrow markings on the old and new filters. I drive on highways every month and used to sneeze a lot when the AC was on in summer, but the odor disappeared immediately after replacing the filter. Now I check it every quarter, especially before the rainy season—it's a must-change to prevent mold growth.

Just helped my neighbor deal with the AC odor in his 2008 a few days ago, and the root cause was the cabin air filter. It's located behind the glove compartment on the passenger side. First, you need to remove the glove box: press both hands against the middle of the compartment and squeeze inward, then slowly pull it downward. The rear cover can be popped open by hand. I recommend replacing it with an activated carbon filter, which can remove formaldehyde and odors. Be careful not to drop any screws into the vents during removal—last time I dropped a nut in there, and it buzzed for half a month before I could get it out.
