The cabin air filter in the Mercedes-Benz GL450 is located inside the glove compartment on the passenger side. Below is relevant information about automotive cabin air filters: Functions of cabin air filter: The cabin air filter ensures tight sealing against the housing to prevent unfiltered air from entering the vehicle interior. It also separates solid impurities such as dust, pollen, and abrasive particles from the air, maintaining clean cabin air free from bacterial growth and creating a healthy environment. Replacement interval for cabin air filter: Automotive cabin air filters are typically replaced every 10,000-15,000 kilometers or once a year. The optimal replacement time is usually after spring, as the air conditioning system sees more frequent use during winter and summer seasons.
I've been driving a Mercedes-Benz GLS450 for several years, and the location of the cabin air filter is quite straightforward—it's behind the glove compartment in front of the passenger seat. To access it, you'll need to remove the glove box first, which is secured with screws or clips. After unscrewing them, carefully pull out the glove box to reveal a housing containing the filter. I’ve replaced it myself a few times, and it’s not difficult—just a Phillips screwdriver is needed. But remember to place some cloth or paper inside the car to catch any small parts that might fall and be hard to retrieve. The filter traps dust and pollen from the air. Since city driving exposes you to poor air quality, I recommend replacing it annually or every 10,000 km. Otherwise, you might notice a musty smell from the AC, especially in summer. The GLS450’s design is relatively user-friendly, though first-timers might find it a bit fiddly—practice makes perfect. When buying a replacement, search online for the correct model match—don’t cheap out on knockoffs, as they can reduce airflow and increase fuel consumption. Regular changes are great for health, especially for those who spend long hours driving, as they protect the respiratory system and help prevent coughing or allergies.
