PM2.5 means that the diameter of the fine particles is less than 2.5 microns, and the PM50 is a fine particle with a diameter of more than 50 microns. Among them, PM50 has the best air quality and large particles. Inhalation will be blocked by nose hair. Conversely, particles smaller than 2.5 microns will enter the body directly, and because the particles are too small, the body cannot discharge itself. As a result, irreversible damage can be caused in various body systems such as the respiratory system, cardiovascular system, reproductive system, and blood system. For example, harmful gases, heavy metals, etc. in PM2.5 are dissolved in the blood and cause great harm to the human body. In addition, it can directly enter the alveoli, and through the blood into the lungs to precipitate, scientifically demonstrated that the human body's physiological structure characteristics have caused the human body to PM2.5 without any filtering, blocking ability, so once entered is permanent, can not be discharged. At the same time, PM2.5 can also directly enter the heart, causing multiple diseases such as myocardial infarction. Inhalation of excessive pN2.5 in infants and children can lead to fetal growth retardation and PM2.5 in low birth weight infants can also cause hematological toxicity, induce thrombosis, and can also cause coagulation abnormalities, leading to cardiovascular disease.

     Studies have shown that the PM2.5 environment will reduce the average life expectancy of people by 8.6 months, directly related to the danger of life. Many elderly people are more likely to suffer from illness in smog weather. It is also due to bacteria and other particles in the air that have become catalysts. It is very easy to induce many diseases.

In this regard, the best solution at present is to place an air purifier indoors.
