Where is the air conditioning filter located in the BMW X5?

[Daedalus]

The air conditioning filter in the BMW X5 is located on the passenger side of the engine compartment. You can see it by removing the front decorative panel. The BMW X5 air conditioning filter should be replaced every 20,000 kilometers. If driving in harsh environments, it is recommended to shorten the replacement interval. The air conditioning filter consists of two components for filtration, and both must be replaced together during maintenance. Function of the air conditioning filter: It filters impurities, tiny particles, pollen, bacteria, industrial exhaust, dust, etc., from the air entering the cabin from outside, improving air cleanliness. This prevents such substances from damaging the air conditioning system and ensures a good air environment for passengers. Maintenance of the air conditioning filter: If the filter is dirty, clean it by blowing compressed air from the opposite side. Hold the air gun about 5 cm away from the filter and blow at 500 kPa pressure for about 2 minutes. The filter easily collects dust, so use compressed air to remove loose particles. Never wash it with water, as this can damage it. Poor maintenance of the air conditioning filter can lead to dust and dirt accumulating on the filter plate, radiator, evaporator, and fin surfaces, causing airflow blockage. This can reduce cooling and heating efficiency, increase power consumption and noise, and shorten the air conditioning system's lifespan. Impact of not replacing the air conditioning filter on drivers: Long-term use without replacement can cause impurities on the filter to mold, producing bacteria and odors, which can harm the health of drivers and passengers and even trigger respiratory diseases. Impact of not replacing the air conditioning filter on the engine: Severely clogged air filters increase intake resistance, reducing engine power and worsening engine performance. This leads to higher fuel consumption and accelerates engine wear and carbon buildup. Precautions for replacing the air conditioning filter: Purchase air conditioning filters from reputable manufacturers and compare their appearance and dimensions. Ensure the vehicle is turned off before replacement. When loosening screws or clips, apply appropriate force. Pay attention to the installation direction to avoid reversing it. After installation, check if the filter is properly seated, ensuring the filtering surface covers the entire air duct without gaps to prevent filtration failure. Precautions for using car air conditioning: Do not turn on the heating immediately when warming up the car in the morning; wait until the engine coolant temperature rises. Avoid setting the air conditioning temperature too high, as prolonged excessive heat can cause drowsiness and affect driving. Also, avoid directing warm air straight at the face. If windows fog up after turning on the heating, increase the fan speed and let it blow longer to eliminate fogging without recurrence. Ventilate the cabin periodically during long drives, as poor air circulation can lead to breathing discomfort over time. Turn off the air conditioning before parking and switch to external circulation with natural air to clean the air conditioning ducts and prevent bacterial growth.
