30% identification of dust mask does not meet the requirements

1n the market, various kinds of masks that claim to be dust-proof and haze proof emerge in endlessly, which often make consumers fussy. Yesterday, in view of the rising consumption of dust masks, the China Consumer Association, together with Chongqing and other five provinces and cities consumer associations, conducted a comparative test on 37 types of masks sold on the market. The results showed that nearly 30% of the products did not meet the requirements

the trademark mark 30% does not meet the requirements

the national labor protection products quality supervision and 1nspection Center (Beijing) was entrusted to carry out the test, referring to gb2626-2006 “respiratory protective equipment self suction filter type anti particulate matter respirator” standard, to test the filter effect, respiratory resistance, leakage and other protective performance of mask products on the market Cost, etc. A total of 37 samples were tested, covering almost all the mainstream brands

“some only identify the size, some use the filter performance as the mask performance publicity, and some products have the behavior of concept hype and false publicity.” According to China’s current relevant standards, mask labels are generally required to indicate product name, trademark or other distinguishing marks, product model, executive standard, filter material grade, manufacturer’s name, and some necessary instructions and warnings. 1n the test, it was found that the identification of most masks was not uniform, and 12 samples were not marked with the production date and validity period, which did not meet the national requirements

the dust-proof effect is not directly proportional to the price

at the same time, due to the lack of relevant product standards for anti haze or anti PM2.5 masks, the Executive Standards of mask samples are not unified. According to the person in charge, the report evaluates the filtering effect and respiratory resistance of the tested masks from no star to five stars. The more stars, the better the filtering effect and the smaller the respiratory resistance

among the test samples, only 12 samples were marked with filter material grade; Filtration effect is five-star, that is, the minimum filtration rate of more than 95% is only 15. The respiratory resistance is often inversely proportional to the filtration effect. There are only five types of products with respiratory resistance of five stars, and the filtration effect of the corresponding products is poor except those with expiratory valve. 1n addition, 12 of the 15 disposable masks tested had a leakage rate of 5 stars

“the lowest price of a mask is 1 yuan, and the highest price is 199 yuan. However, the performance is not directly proportional to the price.” The person in charge said that compared with disposable masks, the price of replaceable filter cotton masks is more expensive, but the dust-proof function is not better, and the filtering effect is generally less than 3 stars. The filtration efficiency of particulate matter is less than 95% of 22

in this regard, China Consumer Association and other consumer rights protection units suggest that the relevant state departments should further regulate the production and sales of mask products, and revise and improve the relevant standards

how to choose a mask correctly

1. The test results show that the knitted cloth masks sold in the small commodity market have poor haze prevention effect, and the masks purchased online have no Chinese logo
