Statistics and research indicate that the number of sand and dust events in East Asia during this period is typically around 5-6, but this year's sand and dust weather has exceeded the average of previous years. Acute exposure of the human respiratory system to high concentrations of sand and dust particles can shorten average life expectancy, increase the incidence of cardiovascular and respiratory diseases, and exhibit a significant lag effect. In addition to the impact of large particles, fine particles (PM2.5) and ultrafine particles (PM0.1) in sand and dust can penetrate the human body due to their small size, posing a greater threat to human health.
Areas with severe sand and dust levels have even issued regulations to suspend outdoor work, underscoring the obvious dangers, as adverse weather can also cause significant harm to human health.
How to take preventive measures?
- Try to avoid outdoor activities, especially for the elderly, children, and those with respiratory allergic diseases, and promptly close doors and windows indoors.
- f you need to go out, you should bring dust prevention equipment such as masks and goggles to avoid damage to the respiratory tract and eyes caused by sand and dust.
- A sandstorm can leave a strong smell of dirt indoors, which can be cleaned with a vacuum cleaner or a damp cloth to avoid the resuspension of dust.
- If possible, equip indoor spaces with air purifiers or air filters, which can purify indoor air and effectively eliminate viruses and bacteria in the air.
- The SAF multistage air filtration system features filters of different filtration levels to reduce the concentration of dust and microbial aerosols in the air. We use bag filters and box filters as two-stage pre-filtration sections to remove coarse and medium-sized particles. The EPA, HEPA, and ULPA filters in the SAF system serve as final stage filters, effectively capturing small particles and bacteria.
