What effect does the weather have on people's lives?
A stable climate with little increase or decrease in air pressure, temperature and humidity is beneficial to people's longevity. The freshest air is not in the morning. On the contrary, air pollution is the most serious in the morning, noon and evening, with peaks at 7: 00 pm and 7: 00 am. In a year, the air is freshest in summer and autumn, and the air pollution is heaviest in spring and winter. The air is fresher and cleaner during the day, noon and afternoon. Wear a mask with good filtration imported from the United States in foggy days. Sources of toxic particles in cities: First, automobile exhaust has good filterability, which can prevent both particles and fog drops. The filtration efficiency is 99.8% for particles as small as 0. 1 micron, and 99.9% for bacteria or virus carriers as small as 0.3 micron (common in droplets). SecureFit patented technology is adopted to adapt to different face shapes and achieve a high degree of fit. For the health of you and your family, wear a mask when you go out.
