The air-conditioning filter element should be replaced every six months.
During the use of automobile air conditioning system, air will flow in blower, evaporation box of refrigeration system, small water tank of heating system and air duct. As long as the blower of the air conditioning system is turned on or the air intake mode is selected for indoor circulation, air will enter the above system regardless of whether the refrigeration device is used. This kind of air will accumulate a lot of dirt such as dust, moisture and bacteria on the surface of the equipment during circulation. Over time, it will breed bacteria such as mold, emit peculiar smell, cause harm and allergic reaction to human respiratory system and skin, directly affect the health of passengers, and the air conditioning system itself will also have faults such as poor refrigeration effect and small air supply.
