What should I do if the haze weather is serious?

The main component of smog is pm2.5 When inhaled into the human body, it first passes through the respiratory tract, which will cause acute upper respiratory tract infection, acute tracheobronchitis, pneumonia and asthma attacks, and induce or aggravate chronic bronchitis. Inhalation will hinder normal blood circulation, leading to cardiovascular diseases, hypertension, coronary heart disease, cerebral hemorrhage, angina pectoris, myocardial infarction, heart failure and so on. And make chronic bronchitis appear a series of diseases such as cor pulmonale. Therefore, outdoor activities should be minimized in foggy days. When you go out, remember to wear a mask for protection. Indoor air is inevitably polluted and needs to be purified. Negative ion air purifier can be used to purify indoor air.

Many experts in the field of air environmental protection in the United Nations have confirmed that ecological negative ions (small particle negative ions) can actively capture small particles of dust, make them coagulate and precipitate, and effectively remove particles below 2.5 microns (PM2.5), even particles of 1 micron, thus reducing the harm of PM2.5 to human health. The purification effect of ecological negative ions on the air is due to the positive charge of negative ions, bacteria, dust and smoke in the air.

The book Environment, Health and Negative Oxygen Ions, edited by Lin Jinming, an expert of China Academy of Sciences, a doctoral supervisor and professor in Tsinghua University, has repeatedly stated that when the concentration of negative ions in indoor air reaches 20,000 per cubic centimeter, the amount of floating dust in the air will be reduced by more than 98%. It has an excellent effect on particulate matter PM2.5 that can enter the lungs. Therefore, the concentration of negative ions in the air is high, the particle size is small, and there are many dust, bacteria and viruses. The most harmful diameter 1um in PM2.5 is almost zero. The book "Application of Air Negative Ions in Medical Care and Environmental Protection" compiled by the expert group of China Air Negative Ions and Ozone Research Association also mentioned many times that a pair of light ions (small particle size negative ions) in the air are as small as 0.0 1? M, the particle floating dust that is difficult to remove in industry, and the settling removal effect 100%.

Ecological small particle negative oxygen ions are equivalent to air negative ions in nature, with the characteristics of small particle size, high activity and long migration distance. Moreover, medical research shows that only small particles of negative ions can act on the human body through the blood-brain barrier and provide medical care. The negative ion air purifier that artificially generates small particle size negative ions can only generate ecological negative oxygen ions with small particle size, high activity and long migration distance by using negative ion converter technology, and then release high concentration negative ions into the air by using nano fullerene negative ion releaser technology, without other derivatives such as ozone and positive ions.
