The cabin air filter in the 2017 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 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.

In my repair experience, the cabin air filter location on the 2017 308 is quite typical - hidden behind the glove compartment on the passenger side. After removing the glove box door, press the clips at the bottom to remove the cover, and the filter housing will be exposed. This design makes DIY replacement fairly convenient with just a bit of finesse. Regular filter changes are absolutely crucial as they block pollen and pollutants, keeping cabin air fresh to prevent allergen buildup. I've seen many vehicles requiring entire AC system repairs due to clogged filters from prolonged neglect, which can cause reduced airflow or foul odors. I recommend annual replacement - a good practice is to smell the AC vents when starting the car; if you detect a musty odor, it's time for action. Maintaining this habit ensures a more comfortable environment both inside and outside the vehicle.

I drive a 2017 308, and the cabin air filter is located behind the glove compartment on the passenger side. The steps are simple: first, open the glove compartment, press down on the clips on both sides to remove it, then take off the filter cover and replace the old filter with a new one. Check it every 12-18 months to avoid dust buildup affecting your health. Doing it yourself saves money and keeps the air inside the car fresh.

As someone who often takes kids out, I pay special attention to the cabin air filter location in my 2017 308—it's behind the glove box on the passenger side. You'll need tools to unscrew the fasteners when replacing the old filter. Clean cabin air is crucial to prevent dust and bacteria from affecting children's health. I make it a habit to change it every six months, opting for thicker filters that trap more contaminants. Combined with regular window ventilation, this reduces odors and makes driving more comfortable. Regular maintenance of this small component can prevent bigger issues down the road.

In cars like the 2017 308, the cabin air filter is typically located behind the glove box on the passenger side, a common layout in many European vehicles. Simply open the glove box, remove the clips, and you'll see the filter housing - it's an easy DIY job that takes just over ten minutes. Choosing the correct model, whether OEM or compatible, is crucial. High-quality filters improve filtration efficiency while reducing energy consumption. Having tested various brands, I found activated carbon filters deliver the best performance and help prolong the AC system's lifespan. Pay attention to replacement intervals - maintaining a healthy car starts with these small details.
