Is It Normal for the Car's Air Conditioning to Get Louder After Changing the Filter?

[DeAndres]

It is normal for the car's air conditioning to become louder after changing the filter. The function of the car's air conditioning filter: It ensures the filter fits tightly against the housing, preventing unfiltered air from entering the cabin. It separates solid impurities such as dust, pollen, and abrasive particles from the air. It adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air and has strong and long-lasting moisture adsorption capabilities. Maintenance of the car's 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 approximately 2 minutes. The air conditioning filter easily accumulates dust, so blowing away loose dust with compressed air is sufficient.
