Where is the cabin air filter located in a BMW 523li?

[DeArthur]

BMW 523LI's cabin air filter is installed inside the glove compartment. Filters dust from the air: Prevents dust from entering the evaporator and forming sludge that can clog it. If the airflow from the vents is noticeably reduced, it indicates a blockage; Purifies the air: The cabin air filter typically contains activated carbon, which can absorb some harmful gases in the air, benefiting health; Temperature control: In the design and manufacture of air conditioners, the temperature is generally allowed to be controlled between 16-32 degrees Celsius. If the temperature is set too low, it not only increases unnecessary power consumption but also creates a significant temperature difference between indoor and outdoor environments. This makes it difficult for people to quickly adapt to temperature changes when moving between rooms, increasing the risk of catching a cold.
