there is no grading mask in Xi’an market

With the cold weather, haze weather will gradually increase, and many citizens have to wear anti haze masks. However, how to choose masks scientifically is a difficult problem. Since November, China’s first national standard for civil protective masks, technical specification for daily protective masks, has been implemented. Can we buy new standard masks in Xi’an

different manufacturers have different standards

people have a headache for buying masks

“in recent years, they have bought more than a dozen anti haze masks, including disposable ones, N95 ones and cotton ones. So far, they don’t know which is better or which is more suitable for Xi’an’s pollution level.” Ms. Gao, who lives in the high tech Zone, said

on Novembe2, a reporter from Huashang daily visited four drugstores in Keji Road, Gaoxin Fourth Road and bianjia village, and found that there are many kinds of masks, some of which are called dust masks, some are called stereo masks, and the prices range from more than ten yuan to twenty or thirty yuan, but there are no signs of D, C, B, a and other levels in accordance with the new “standard”, The sales staff of the drugstore said that they had not seen the product with the grading label. A reporter from Huashang daily carefully examined the packaging and found that the technical standards on the product description of almost every mask were different

class a masks should deal with the most serious pollution

some enterprises are stepping up the manufacture of new products

according to the technical specification for daily protective masks, the concentration of PM2.5 inhaled can be reduced to 75% after wearing masks μ According to the effect, it can be divided into four grades: Grade D, grade C, grade B and Grade A. grade D is suitable for moderate (PM2.5 concentration ≤ 150 g / M) μ Grade C is suitable for severe pollution (PM2.5 concentration ≤ 250 g / M) μ Grade B is suitable for severe pollution (PM2.5 concentration ≤ 350 g / M) μ The concentration of Grade A in PM2.5 reached 500 g / m μ G / m. The corresponding protective effects of all levels were no less than 65%, 75%, 85% and 90% respectively. Consumers can choose the right mask according to the air quality, so as to make the air quality in the inhaled body reach the level of good or above. 1n addition, the standard clearly states that the standard “does not apply to masks for children”

when will the new standard products come into the market? According to the relevant person in charge of China 1ndustrial Textile 1ndustry Association, which participated in the formulation of the standard, some enterprises are stepping up the manufacturing of new products. A reporter from Huashang Daily called a mask manufacturer in Xiamen, and the staff said that the new standard masks have not been produced yet, and the standard of medical protective masks is still in use
