I also encountered this issue with my own Mercedes-Benz GL450. The cabin air filter is usually located above the footwell area on the passenger side. Specifically, it's behind a small panel beneath the dashboard near the passenger footrest. You'll need to remove some small clips or screws to open the panel, and then you can see the filter slot. DIY replacement is quite simple—I check it every 15,000 km and buy compatible filters online to replace myself. If not replaced, accumulated dust can affect cabin air quality, especially harmful for the breathing of elderly and children. Mercedes' design is fairly user-friendly—I’ve done it a few times and it takes about 10 minutes. The key point is to ensure the filter’s arrow direction isn’t installed backward, otherwise filtration efficiency drops. The location is hidden but easy to find, and fellow owners’ shared tips are reliable. If in doubt, always check the manual.

As a new car owner, I was curious about where the GL450's cabin air filter is located. Turns out, it's under the front passenger seat, specifically behind a plastic panel in the footwell area. You just need to gently pry open a small cover to replace the filter. The placement is quite clever—it doesn't get in the way, though it took me a moment to locate it initially. Following a YouTube tutorial made the process smooth. Remember to change it every 20,000 kilometers to prevent musty or unpleasant odors from the AC. The area is free of obstructive wiring, making it safe to handle. An OEM filter works perfectly—just align it correctly during installation. Keeping it clean is great for your respiratory health. Sharing this straightforward tip saves everyone unnecessary hassle. Once you know the exact location, maintenance becomes much easier.
