(Summary description)Wearing activated carbon masks is the most effective
 
In recent days, Beijing has experienced the fourth haze weather of this month. For the sake of health, people began to take protective measures, and various masks also sold well. So, which kind of mask can effectively block PM2.5 particles?
 
Yesterday, the reporter walked into the environmental measurement and control optimization research center of China Academy of Building Sciences with four kinds of masks purchased from the market. After professional testing, it was found that masks with activated carbon filters are more suitable for wearing in haze weather. On the contrary, gauze masks can hardly block fine particles.
 
Investigation: gauze masks are out of stock
 
"Sorry, gauze masks have been out of stock for several days." Yesterday afternoon, in a drugstore on the South Beach, a salesperson answered the reporter. According to her observation, many people have come to buy masks these days, "thick gauze masks are the most popular." In contrast, disposable masks are not so popular.
 
In some online stores, N95 and Kn90 masks with activated carbon filter are on sale. The reporter saw that some online stores sold 78454 N95 masks in 30 days.
 
Experience: the mask with activated carbon filter screen is poor in comfort
 
Before the experiment, the reporter bought four kinds of masks: 24 layer gauze masks, disposable medical masks, N95 masks, and Kn90 masks with activated carbon filters. The reporter respectively experienced the wearing of these four kinds of masks. The results showed that wearing N95 masks and Kn90 masks will make you feel uncomfortable breathing, and the comfort is worse than that of gauze masks and disposable medical masks.
