What to Do When There's a Sour Smell from the Car Air Conditioner?

[LaEva]

Car air conditioners emitting a sour smell may be due to unclean air filters, dirty air ducts, or accumulated dust on a damp evaporator. Relevant explanations are as follows: 1. A large amount of impurities and dust can generate various molds harmful to human health. Besides timely cleaning of the evaporator (the air conditioning system is generally cleaned once a year, preferably before summer), it is also recommended to replace the air filter and clean the air conditioning system. 2. Skillful use of the air conditioner can effectively keep the evaporator dry, reducing the breeding of bacteria and mold. Timely replacement of the air filter is also a very effective method. Extended content: The function of a car air filter is to filter the air entering the car interior from the outside, improving air cleanliness. Common filtering substances include impurities in the air, such as tiny particles, pollen, bacteria, industrial exhaust, and dust.
