The public materials show that many brands have been punished for false propaganda. In March of last year, the Shanghai Municipal Administration for Industry and Commerce announced that the price of Jianyi PM2.5 professional respirator exhaust gas treatment equipment claimed on the outer packaging of goods that “useful to isolate PM2.5 particles from the air, the filtration rate was over 99%, and it was isolated In the air, the virus filtering rate reached 99.9%. However, the practice inspection results did not reach the filter rate claimed by the advertisements, and constituted false statements and were fined 100,000 yuan. In the same month, the Shanghai Bureau of Quality Supervision released sample inspection results for 69 batches of masks, and the lack of masks for the effectiveness of anti-caries to reach the state's relevant regulatory requirements was limited to the production of a Guangzhou Guanhua P&L Products Co., Ltd., and Tmall's daily domestic use. The measured value of the filtering power of the mask (specification: M-6800) sold by the franchised store is only 1.1%. Some masks are not strictly controlled by manufacturers, and there may be doubts about excessive formaldehyde content, high pH, ​​and overshoot of fluorescent agents. A well-known online shopping channel sells for about 5 yuan a "3M" a KN95 mask, some shops can buy a few cents, and some are priced at a hundred dollars. Although there is a difference in quotations, these goods will not ignore the promotion of "prevention of firefighting," but the practical results are quite different. In fact, many masks on the market have been marked with filtering power. Most of them claim to be over 90%. However, from the results of public inspections now, there are not many masks that can reach the claimed power. In May 2014, the Consumer Protection Committee of Zhejiang Province purchased 25 batches of samples of anti-mite masks. The price of the exhaust gas treatment equipment was found to be no more than 90%. In December 2015, Shanghai Customs successively seized two batches of N95 masks that were exported outside the country as “3M†brand, nearly 120,000. These masks are rough and the use of residual filter media not only fails to protect them, but also harms the body.
