Some people think that air pollution is divided into low and peak seasons, severe smog in winter, high PM2.5 index, poor air quality, and serious indoor air pollution, while summer air is good, cloudless and sunny, so there is no indoor air pollution. but you know what? In the hot summer, we may not have to worry about the smog like autumn and winter, and we can open the windows to ventilate as much as we want, but the hot outside forces us to close the doors and windows. Without opening windows for ventilation, indoor pollution will intensify. Many people don't know that indoor air pollution in summer may be more serious than in winter. In summer, indoor air conditioners have also become the top source of indoor pollution.

Why is air conditioning one of the leading causes of indoor air pollution?

1. The indoor air is not convective

When the air conditioner is turned on, all the doors and windows in the room will be closed, resulting in poor indoor ventilation and a corresponding decrease in the convection between indoor air and outdoor air, preventing effective diffusion of pollutants, such as dust mites, pet hair, dander, and mold. Or volatile organic substances, cigarette smoke, and particles with bacteria or viruses.

2. The interior of the air conditioner is not clean

The air conditioner is mainly used to adjust the temperature and humidity of the indoor air, which requires the participation of moisture in the air to play a role, so that the environment inside the air conditioner becomes dark and humid, which is suitable for the growth and reproduction of mites, mold, and viruses in the air conditioner . They are concealed in the air conditioner, continuously enter the indoor air through the circulating airflow, and diffuse in every corner of the room, which can make people easy to catch influenza, tonsillitis, pneumonia, etc.

The "2018 Indoor Air Health White Paper" issued by the Chinese Center for Disease Control and Prevention pointed out that air conditioners accounted for 42% of the top indoor air pollution sources, and the pollution rate of household air conditioners was as high as 88%. Such a high pollution index shows that the pollution situation cannot be ignored! What impact does indoor pollution caused by air conditioning have on the human body?

Effects of Indoor Pollution Caused by Air Conditioning on Human Body

1) Affect the respiratory system

Turn on the air conditioner and close the doors and windows for a long time, so that indoor and outdoor air does not circulate, and various pollutants are easy to accumulate, and the respiratory system is the place where pollutants are most likely to attack, and it can increase the risk of abnormal lung function in children by 30%-70%.

2) Cause an allergic reaction to irritation

Dirty dust filters and air ducts in the air-conditioning or ventilation system can increase the growth rate of mold and dust mites, which can easily cause irritation and allergic reactions in the human body. Symptoms include sneezing, watery eyes, coughing, shortness of breath, skin sensitivity, etc.

3) Cause air conditioner disease

Symptoms such as dizziness, headache, loss of appetite, upper respiratory tract infection, and joint pain caused by being in an air-conditioned environment for a long time are called air-conditioning diseases. In fact, there is no such thing as "air-conditioning disease" in medicine. It is a sociologically diagnosed disease name. Usually, any disease related to or caused by air-conditioning can be called "air-conditioning disease". It mostly occurs in summer, and the elderly, children and women are susceptible groups. The respiratory tract, joint muscles, and nervous system are most susceptible to involvement.

Obviously, the main cause of indoor pollution caused by air conditioning is the accumulation of pollutants. If you want to turn on the air conditioner indoors and improve the indoor air quality, you must first clean the air conditioner regularly, and then open the windows regularly for ventilation. You can also use a fresh air system for ventilation, and you must have safe and effective air purification products to assist.
