Where is the cabin air filter located in a 2017 Peugeot 308?

The cabin air filter in the 2017 Peugeot 308 is located beneath the right front windshield, positioned between the rain gutter and the engine firewall. When driving with the air conditioning on, the system draws outside air into the vehicle cabin. However, this air contains various particles such as dust, pollen, soot, abrasive particles, ozone, odors, nitrogen oxides, sulfur dioxide, carbon dioxide, benzene, etc. Without the cabin air filter's filtration, these particles entering the cabin would not only contaminate the air conditioning system and reduce cooling performance, but also cause allergic reactions, lung damage, ozone-induced irritation, and odor-related discomfort - all of which compromise driving safety. Steps for replacing the cabin air filter: 1. Turn off the engine (do not start the vehicle). 2. Locate the engine hood release lever at the lower left of the driver's footwell, lift it to release the primary latch, then open the secondary latch to raise the hood. 3. Secure the hood with the support rod. 4. Using a 10mm wrench, remove the three to four bolts securing the right front windshield rain gutter cover near the engine firewall. 5. After removing the protective cover, the hidden cabin air filter will be visible. 6. Remove the old filter and install the new one. 7. Reassemble components in reverse order of removal.
Last year, I replaced the cabin air filter for my 2017 Peugeot 308, which is located behind the glove box. First, you need to open the glove box on the passenger side, locate the two clips inside, press them down, and gently pull out the entire glove box. After removing it, you’ll see a plastic cover with several small screws—unscrew them to pull out the filter housing. The whole process can be done with a Phillips screwdriver, but be careful not to lose the screws. The filter should ideally be replaced every 12 months or 15,000 kilometers; otherwise, dust buildup can cause a musty smell when the AC is on and affect breathing, especially for someone like me who’s prone to sneezing. You can buy the new filter online—opt for one with activated carbon for better filtration—and save on repair costs by doing it yourself. Regular interior cleaning also helps extend the life of the AC system.
