As the weather turns cold, haze will gradually increase, and many citizens will have to wear anti-snoring masks. However, how to scientifically buy masks is a difficult problem. Since November, China's first national standard for protective masks for daily use has been implemented. Is it possible for Xi'an to buy new standard masks?

All manufacturers have different standards

Citizens buy masks for headaches

"In recent years, I have also said that I have bought more than a dozen anti-mite masks, one-off, N95, and cotton. I don't know which one is better and which is more suitable for Xi'an's pollution level." District of Ms. Gao said.

On November 2nd, a reporter from Huashang Daily News visited four pharmacies of Science and Technology Road, Gaoxin Silu and Bianjia Village. They found that there were many types of masks, some were called dust masks, and some were called three-dimensional masks. Prices ranged from a dozen to two or three. Ten dollars, but did not identify the D, C, B, A grade, etc., in accordance with the new "Code", pharmacy sales staff said they have not seen this graded product. China Business Daily reporter carefully examined the packaging and found that almost every technical description of the mask was different.

Class A masks deal with the most serious pollution

Some companies are stepping up manufacturing new products

“Technical Specifications for Daily Protective Masks” stipulates that after wearing a mask, the concentration of inhaled PM2.5 can be reduced to 75μg/m or less, so that the air quality of the filtered inhalation body can reach good and above levels, which is only qualified and according to the effect. Divided into Class D, Class C, Class B, Class A and Class IV, in which class D is adapted to moderate (PM2.5 concentration ≤ 150 μg/m) and below pollution, class C to severe (PM2.5 concentration ≤ 250 μg/ m) and below pollution, class B applies to severe pollution (PM2.5 concentration ≤ 350 μg/m), and class A uses when PM2.5 concentration reaches 500 μg/m. The corresponding protective effect at each level is not less than 65%, 75%, 85%, and 90%, respectively. Consumers can choose the right mask according to the air quality, so that the quality of the inhaled air can reach good or above. In addition, the standard clearly states that this standard "does not apply to children's masks."

When will the new standard products be listed? According to the relevant person in charge of the China Industrial Textiles Industry Association that participated in the development of the standard, some companies are stepping up manufacturing new products. China Business Daily reporter called Xiamen mask manufacturer, and the staff said that it has not yet started to produce new standard masks, which is based on the standard of medical protective masks.
