Haze Prevention Should Not Be Worn Frequently.

< p > recently, "Beijing intends to invest in 760 billion air pollution control", making air quality, respiratory protection and other related topics again become the focus of discussion.

The sale of masks also brings some consumers' doubts: will the wearing of industrial masks be harmful to the respiratory system? Where is the industry standard for civilian masks? Experts say that industrial masks and civil respirators are strictly differentiated and limited, and if used unhealthfully, they will be harmful to health.

The reporter recently learned that at present, China's industrial a target= "_blank" href= "http://www.91se91.com/" > textile < /a > Industry Association has completed the first draft of the standard proposal for civil masks, will be reported to the national standards committee, and strive to improve the situation of haze mask market.

< p > online shopping data show that in 2013, consumer spending on protective products and indoor sporting goods amounted to 870 million yuan, a total of 4 million 500 thousand times.

In addition, the number of masks and air purifiers increased by 181% and 131% respectively compared with 2012.

However, the data did not count the number of consumers and the amount of consumption of products purchased offline.

< /p >

< p > there are also worries behind the hot sales of protective products such as masks.

At present, there is no national standard in the field of civilian masks in China.

< /p >

< p > it is understood that most of the industrial masks on the market are European standards starting with N95 and N90, or FFP, but the masks that carry out these standards have strict wearing conditions.

Some consumers wear industrial masks for a long time and are prone to dizziness, nausea and vomiting.

In fact, industrial masks have poor preventive effects on viruses and bacteria in addition to their poor air permeability.

< /p >

< p > although industrial masks can effectively filter fine particles such as PM2.5 or even less, the water vapor contained in human breath is easily attached to the inner walls of industrial masks, so that bacteria and viruses attached to PM2.5 are nourished, making industrial masks become culture dishes for bacteria and viruses, so that consumers may be contaminated by two times.

< /p >

< p > according to relevant data, our country's < a href= "http://www.91se91.com/news/index_s.asp" > masks < /a > national standard is GB2626-2006, which is suitable for industrial masks.

Similar to the US standard, it is classified into KN class suitable for non oily particulate matter filtration and KP class for oil particle protection.

Among them, the filtration rate of KN90 is greater than or equal to 90%, while the filtration rate of KN95 is greater than or equal to 95%, and the filtration rate of KN100 is greater than or equal to 99.97%.

Therefore, fundamentally speaking, there is no national standard for civilian masks.

< /p >

< p > on the one hand, businessmen are driven by the "haze" economic interests, on the one hand, the lack of standards for civilian masks, leading to the current market of all kinds of "anti haze" banner masks, while the relevant formal enterprises have a higher voice for the industry standard of civilian masks.

"There are strict conditions for wearing industrial masks, such as wearing a medical assessment in Germany for more than half an hour a day," he said.

Zhao Danqing, chairman of the green shield mask, said that the key to respiratory protection is to prevent bacteria and fine particles.

< /p >

< p > although civil respirators are not as good as industrial masks in terms of airtightness, they are easy to clean and suitable for long wear, and some brand products do have antibacterial functions.

If we can establish the antibacterial standards of the civil respirator industry, we can effectively block fake and shoddy products and protect consumers' daily protection.

It has been revealed that the China Industrial Textiles Association has completed the first draft of the civil "a href=" http://www.91se91.com/news/index_q.asp "Mask" standard < /a >, and will be reported to the National Standards Committee.

However, the introduction of a standard must be carried out through rigorous procedures. The industry expects that the implementation of the standard will be the fastest in 2015.
