Where is the cabin air filter located on a BMW 528?

The cabin air filter on a BMW 528 is located on the passenger side of the engine compartment and near the left foot position of the front passenger seat. Here are several functions of the cabin air filter: 1. It ensures the filter tightly adheres to the housing, preventing unfiltered air from entering the cabin. 2. It separates solid impurities such as dust, pollen, and abrasive particles from the air. 3. It prevents car windows from fogging up, ensuring clear visibility for drivers and passengers, thereby enhancing driving safety. It provides fresh air to the cabin, preventing occupants from inhaling harmful gases and ensuring driving safety. It also effectively sterilizes and deodorizes.
I find changing the air filter on the BMW 528 quite interesting, mainly because its location is a bit hidden. It's behind the glove compartment on the passenger side, and you need to bend down to see it. When I changed it myself, I realized you first need to remove the panel under the glove compartment, which is secured by clips without any screws. After removing it, you'll see a black plastic cover. Use a T20 screwdriver to unscrew the four small screws in the corners, and then you can take the cover off. The filter inside is placed at an angle, so make sure not to install it backward—pay attention to the arrow direction. The most troublesome part is having to lie down on the passenger side floor to do the job, which might be a bit tough for those with back issues. Remember to replace it every 20,000 kilometers, otherwise, the AC might start emitting a musty smell. Also, this area tends to accumulate a lot of dust, so don't be surprised if you find leaves or other debris when cleaning.
