The cabin air filter in a BMW 520 is located behind the glove compartment on the passenger side. Functions of the cabin air filter: Ensures the filter fits tightly against the housing to prevent unfiltered air from entering the cabin. Separates solid impurities such as dust, pollen, and abrasive particles from the air. Adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air; provides strong and long-lasting moisture adsorption. Prevents car windows from fogging up, ensuring clear visibility for drivers and passengers and safe driving. Supplies fresh air to the cabin, preventing occupants from inhaling harmful gases and ensuring driving safety. Effectively sterilizes and deodorizes. Cleaning the cabin air filter: The filter is prone to accumulating dust; use compressed air to blow away loose dust. Never wash it with water, as this can easily damage it. Over time, the activated carbon filtration function of the cabin air filter diminishes, so it is recommended to replace the filter at a 4S shop.
