Is it necessary to clean the car's evaporator box? Why?

[LaJuliet]

Cleaning the evaporator box is very necessary. Because the car's air conditioning evaporator box operates in a damp and stuffy environment, it is prone to breeding harmful bacteria. If the evaporator box is not cleaned regularly, harmful bacteria will multiply in large numbers, posing a threat to the health of passengers. Moreover, due to the small interior space of the car, bacteria can spread more easily, creating significant health risks. Therefore, it is recommended to clean the car's evaporator box regularly. Here is some relevant information: Before using the car's air conditioning, in addition to routine maintenance, it is best to perform a cleaning, with a focus on the evaporator box. The car's air conditioning evaporator box is an important cooling component in the car's air conditioning system, which is in a closed state with a dark and damp internal environment. Fine impurities, dust, germs, nicotine, and other particles in the air can easily adhere to the evaporator box along with condensed water. Over time, a large amount of scale accumulates, which can easily breed harmful bacteria.
