Media said improper use of masks

Recently, “Beijing plans to invest 760 billion yuan in air pollution control”, which has once again become a hot topic for discussion on topics such as air quality and respiratory protection. Accompanied by the hot issues of masks, such as "industrial masks flooding the civilian market" and "face mask industry standards are not uniform" and so on also received considerable attention. In this regard, experts said that industrial masks and civilian masks have strict differences and limitations, if improper use of health hazards.

According to online shopping data, consumer spending on protective products and indoor sports goods reached 870 million yuan in 2013, totaling 4.5 million purchases. In addition, the number of people who bought masks and air purifiers rose by 181% and 131% respectively compared to 2012. While the sales data of protective products such as masks has become more and more popular, problems have also arisen. Some consumers pointed out that wearing industrial masks for a long time is prone to dizziness, nausea, and vomiting. It is understood that most of the industrial masks on the market are based on the American standards beginning with the N95, N90, or the FFP, but the masks that implement these standards have strict restrictions on wearing conditions.

It has been reported that German labor insurance regulations require that industrial masks should not be worn for long periods of time in non-extreme working environments. In addition, if you wear an industrial mask, you should also undergo a comprehensive physical examination to avoid damage to the user's body due to the tightness of the industrial mask.

In fact, industrial respirator is not good for the prevention of viruses and bacteria except for poor air permeability. The key to respiratory protection is to prevent bacteria and fine particles. Although civilian masks are not as good as industrial masks in terms of hermeticity, they are easy to clean, suitable for long periods of wear, use many times, have little physical damage, and some brands of masks have antibacterial functions. Taking the domestic first-brand green shield of PM2.5 mask as an example, through the outer layer of Kanglun antibacterial fabric and the enclosed micro filter, it can fight against the “two fine” in the air (that is, the fineness represented by PM2.5). Particulate matter and bacterial viruses represented by N1N1 and NDM-1) achieve full and effective protection.

In addition, for the phenomenon of “industrial masks flooding the civilian mask market”, Zhao Danqing, head of the Green Shield masks, said: “The mask market in China is rather confusing. It is not only full of fake counterfeit masks but also has not yet been introduced in the field of civilian masks. As a result, many elderly people, children, and pregnant women use industrial protective masks, but in reality, these groups are not suitable for wearing industrial masks. Moreover, the bacterial viruses that are trapped in the smog particles are also factors of health damage, but they are also harmful to bacteria and viruses. Protective industrial masks are not involved.”

It is understood that there are no national standards for civil masks. Some experts pointed out that blind purchase of industrial masks by consumers reflects the confusion in the standards of the mask market in China, and consumers have mistakenly used industrial masks for routine protection in the event of panic and lack of understanding. Therefore, the state should introduce the standard of civilian masks as soon as possible at the industry level.
