These smells will directly pollute the indoor air with air conditioning, causing respiratory diseases. A large number of experiments show that water vapor attached to the evaporator of air conditioner will produce at least three kinds of molds harmful to human health: Aspergillus, Penicillium and Penicillium. This is not only a bad smell, but also directly affects our health.
In addition, these molds can cause adverse reactions, such as headache, fever, sudden sore throat, tonsil infection, asthma, flu symptoms, dermatitis and difficult wound healing.
Extended data:
There are two main reasons why air conditioners always smell:
1. The musty smell is mainly produced in the air conditioner evaporator. Darkness, humidity and warmth are the three conditions for mold growth. Under the above conditions, almost all air conditioners can't avoid mold growing on the evaporator. Generally, after one or two years of air conditioning, there will be an unpleasant sour smell, which is more likely to be produced in humid and warm areas.
2. The frequency of using air conditioners has increased. Air conditioning system is the place where bacteria and mold gather, especially the filter screen. We used it for a long time, and the filter screen was covered with dirt, which slowly gave off a bad smell.
