Recently, the Shanghai Municipal Bureau of Quality and Technical Supervision announced the results of quality and safety risks for the masks claiming “PM2.5 protectionâ€. Among the 69 samples, over 80% of the products were unqualified, and well-known brands such as 3M and Green Shield were on the list. Yunnan Baiyao smog protective mask has the lowest filtration efficiency, only 24.2%.
Barbaric growth
"The protective masks have been completely barbaric in recent years. Not only do they have no industry associations, but also industry standards. They are running all the way, and in the peak season of autumn and winter, many companies are growing by hundreds of percent." Yesterday, a well-known protective mask agent who did not want to be named revealed in an interview with the author.
On the same day, the results of the anti-mite mask test announced by the Shanghai Municipal Bureau of Quality and Technical Supervision have just been announced. Among the 69 batches of samples, the measured values ​​of the filtration efficiency of 56 batches of masks are lower than the reference value by 90%, accounting for the proportion of the total number of samples. More than 80%;
16 batches of mask identification information is incomplete, unmarked product implementation standards or production date; 24 batches of textile mask fabrics or linings have measured values ​​of more than 8.5, accounting for 70% of the total number of textile masks.
Not only that, but in this shocking list of unqualified brands, including 3M, Green Shield and Yunnan Baiyao, the well-known brands are not spared. In terms of the most basic filtration efficiency, the filtration efficiency of 3M resistant comfort masks in the United States is 81.3%. The filtration efficiency of the domestic green shield PM2.5 antibacterial anti-mite mask and non-woven mask (adult models) were 53.5% and 66.2%, respectively, while the filtration efficiency of Yunnan Baiyao smog respirator was 24.2% "taken down".
Yesterday, 3M Company responded to the author's interview on this matter and said that it has been informed of the matter and is communicating with the Quality Supervision Bureau and believes that there is a misuse in this standard test.
"Objectively speaking, the technical level of the various companies on the mask filter is not so great, at least 90% in the test environment, such a low filtration efficiency, may be because the quality inspection department this time The evaluation is the filtering effect of the final product.†Yesterday, Song Guangbin, general manager of Beijing Wanshengren and Technology Co., Ltd. e-commerce division, said in an interview with the author.
But he also stressed that the final product, the protective effect of the protective mask, should be the standard for evaluating the quality and quality of a mask.
"The markings on the outer packaging are definitely the effect of the filter. What 99% and 100% are the experimental data blown out in the air duct, not the 992.5 PM2.5 that you wear," the aforementioned distribution The merchant told this newspaper, "The state does not stipulate that it is necessary to write the final product data, and no one will take the initiative to write it. Anyway, all brands sell very well."
The author learned from a number of mask dealers that the standard adopted by the Shanghai Municipal Bureau of Quality and Technical Supervision for this spot check is GB2626-2006 "Respiratory protective equipment - self-priming filter type anti-particle respirator", this standard is mainly It is an industrial standard that includes filtration efficiency and other indicators that are higher than civilian standards.
The domestic mask standards are also very few. At present, there can only be one "2626" standard as a reference, and the new standard of "Daily Protective Mask Technical Specifications" for civil use is still in the process of formulation, so the quality supervision department proposed Standard testing is also limited. Most companies are setting their own standards and then go to the quality supervision department for filing, so all kinds of anti-mite masks are also "self-talking."
However, the market data is not ambiguous - data from Tmall and Taobao show that in 2014, in the mask category, the turnover ranked 3M116 million, Green Shield 18.6 million, Weikang 10.83 million, Ito good 9.53 million and Totobobo859 million.
A corresponding set of 2013 data shows a similar curve - in that year, consumers spent 870 million yuan on protective products and indoor sporting goods, of which the mask market showed a blowout status on Tmall and Taobao. The number of people buying masks and air purifiers has increased by 181% and 131% respectively compared to 2012.
"This is also a problem we are worried about now. With the large sales of protective masks and the irregularities of the industry, consumers' trust in this product category is also beginning to decrease." Zhejiang Provincial Safety and Health Protective Products Industry Association President and Construction Lin Jinxiang, chairman of Deshi Chaomei Daily Chemical Co., Ltd., said in an interview with the author yesterday.
He told the author that because of the weather and market reasons, the sales of national protective masks appeared in the “nearly crazy†blowout in the second half of 2013 – “seeing the money is very profitable, many companies that are not in this industry are also coming in. Production and sales have led to a large accumulation of products and a decline in consumer confidence."
