Here is some relevant information: 1. The car air conditioning filter mainly helps to filter out fine impurities and dirt in the car, thereby providing a more comfortable and superior in-car environment. During the operation of the engine, a large amount of outside air is required for support, and impurities will inevitably be inhaled. The air conditioning filter will filter out impurities and microorganisms in the air. 2. When the airflow from the car's vents is significantly weaker than before, the filter may be clogged with dust and needs to be replaced. 3. When you notice an unusual smell from the air conditioning, such as sour or foul odors, besides replacing the filter, the entire ventilation system should also be checked. If you live in a city with a lot of wind, sand, and dust, it is recommended to shorten the replacement cycle. If you live in a city with fresh air and a clean environment, you can appropriately extend the replacement cycle of the air conditioning filter.

I've been driving a Peugeot 307 for quite some years, and the cabin air filter is located behind the glove compartment in front of the passenger seat. You'll need to open the glove box door first, where there are usually plastic clips or small screws holding it in place—gently pry them open or unscrew them by hand or with a small tool. After removing the glove box, you'll see a square filter housing; lift the cover to pull out the old filter and replace it with a new one. It sounds simple, but the first time you do it, you might feel a bit flustered, especially since the clips can break easily. I change mine every six months—they're inexpensive and easy to buy online with matching model numbers. Over time, the car's AC can start blowing musty air or dust, and replacing the filter significantly improves air quality, which is especially beneficial for people with allergies. Breathing clean air inside the car makes driving much more pleasant. Remember to align the arrow on the new filter with the airflow direction to avoid reducing filtration efficiency. If you're not keen on DIY, any regular repair shop can handle it quickly—don’t wait until summer when the odor becomes unbearable.

As someone who frequently helps friends with car repairs, the Peugeot 307's cabin air filter setup is quite practical—it's hidden behind the glove compartment on the passenger side. Removing the glove box isn't overly complicated, usually secured by three or four clips or screws. Once removed, you'll see the filter housing. The key during replacement is to avoid excessive force that could damage plastic components. The old filter might be clogged with dust or leaves. I recommend checking it once or twice a year, especially during pollen season or in dusty areas. Installing a new filter improves air filtration efficiency, reduces pollutant buildup inside the car, and makes the AC quieter and cooler during drives. Avoid overloading the glove box to prevent clip deformation that could hinder future access. For filter type, activated carbon versions are recommended for better odor absorption—priced around a few dozen RMB, DIY replacement saves money and brings a sense of accomplishment.

Last time I found the location of the Peugeot 307's cabin air filter myself, it's quite simple to remove behind the glove box on the passenger side. Just open the glove box door, unclip the fasteners with a pull, then directly pull out the old filter and replace it with a new one. I tried it once and it wasn't too difficult, saving some maintenance costs. After replacement, the air inside the car became much fresher.
