Where is the cabin air filter located in a BMW 318li?

The cabin air filter in a BMW 318li is located beneath the glove compartment on the passenger side. Air filtration: The cabin air filter ensures tight sealing against the housing to prevent unfiltered air from entering the vehicle interior. It effectively separates solid impurities such as dust, pollen, and abrasive particles from the air. Additionally, it adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, and other airborne contaminants with strong and long-lasting moisture absorption capabilities. Deodorization and sterilization: It prevents windshield fogging, ensuring clear visibility for safe driving. The filter provides fresh air to occupants, protecting them from inhaling harmful gases and enhancing driving safety. It also delivers powerful sterilization and odor elimination functions.
When helping my cousin replace the air filter in his BMW 318li, I realized you have to empty the glove box first. Reach your right hand inside and feel along the right inner wall - there's a plastic clip that needs to be lifted upward. The entire glove box should be pressed downward to remove it, never yank it forcefully. After removing the rear cover panel, you'll see the rectangular filter slot. Remember to install the new filter with the arrow facing downward - last year a repair shop apprentice installed it backwards, resulting in dusty smells from the AC. Actually, DIY replacement takes at most 20 minutes - charging over 300 yuan for labor at the dealership is just robbery. I recommend the Mann CU23009 filter - half the price of OEM with an added activated carbon layer.
