Inspection Of Over 6 Of Mask Products Has Poor Filtering Effect.

< p > the world's < a target= "_blank" href= "http://www.91se91.com/" > clothing < /a > a target= "_blank" href= "_blank" > shoes "< > hat net" Xiaobian "to introduce the super 6 mask products filtering effect is not good.

< /p >

< p > haze weather with fire haze mask.

"PM2.5 protection", "isolated dust", "anti haze"...

There are many kinds of masks with various protective functions on the market. What's the effect of them?

< /p >

Before "P", the Shanghai municipal quality and Technical Supervision Bureau issued a monitoring result of the safety risk of the mask products sold in the Shanghai market.

The results showed that the filtering effect of over 6 products was not good.

"Green Shield", "Itou Ra products" and other domestic hot sales anti haze mask brands are on the list.

< /p >

< p > the standards for monitoring are gb2626-2006 "respirator and respirator self-priming filter particulate respirator", GB15979-2002 "Hygienic standard for disposable sanitary products", gb18401-2010 "national a target=" _blank "href=" http://www.91se91.com/ "> spinning" /a > Product basic safety technical specification "and other national standards.

For the identification, filtration efficiency, microbial indicators (bacterial colony count, coliform group, pathogenic pyogenic bacteria and fungal colony count), textile safety technical requirements (formaldehyde content, pH value and decomposable carcinogenic aromatic amine dye), etc.

< /p >

< p > filtering efficiency is most concerned by the public.

This index refers to the percentage of respirators to filter airborne particulates under specified conditions.

Its height directly reflects the effect of respirator particles.

< /p >

< p > but the results showed that the filtration efficiency of 24 batches of respirators in the 38 batches of respirators tested was lower than the 90% minimum requirements stipulated in the standard (gb2626-2006); the filtration efficiency of the 1 batches of respirators was lower than that of the indicated 95%; 21 batches of products were not marked with filter grades; 6 batches were not marked with the implementation standards of the products.

< /p >

Among the 24 batches of products with filtration efficiency below 90%, the "Green Shield PM2.5" respirator is sold in the major online stores. P

After testing, the Green Shield PM2.5 non-woven mask (adult type), Green Shield PM2.5 antibacterial anti haze mask (light ventilation type), Green Shield PM2.5 anti bacteria and anti haze mask produced by Shanghai Xingnuo polyamide fiber technology Co., Ltd. were measured at 64.3%, 86.3% and 10.3% respectively.

< /p >

< p > for this reason, Guan Lijun, marketing manager of Shanghai Xingnuo Nylon Fiber Technology Co., Ltd., said that the products of the company are strictly in accordance with the standards set by the enterprise.

For the standard gb2626-2006 used in the monitoring, she said, "the standard is formulated for industrial dust respirators and is not applicable to civilian respirators."

She also stressed that the standard used for the production of mask in Xingnuo Kang Lun has been put on record by the local quality supervision department.

< /p >

< p > by reporter, there is no prevailing standard for the country and industry in China.

Masks are mostly manufactured according to their internal standards.

< /p >

< p > the value of Ito's good pm2.5tm respirator (non-woven fabric) and Ito's good pm2.5tm respirator is 17% and 10.7% respectively, which is produced by Xuzhou badse sanitary products Co., Ltd.

< /p >

The head of marketing department, P, also raised objections to the above monitoring results.

He believes that under different testing standards, the results of products displayed are quite different.

Mr. Bader has not received any notice about the shelf or related processing of his products.

< /p >

< p > in addition, the monitoring report also shows that many products have pH value exceeding the standard and not marking the grade of filter material.

< /p >

< p > e-commerce website is a main channel to prevent haze mask sales.

"One shop online supermarket" staff told reporters that all irregularities, products with quality defects, they will all be off shelves.

At present, according to the monitoring report released by the Shanghai Quality Supervision Bureau, the relevant departments of "online supermarket of No. 1 store" have already begun to investigate and deal with it.

< /p >

< p > Jingdong mall also said that products sold on the platform < a href= "http://www.91se91.com/news/index_f.asp" > masks < /a > products have been verified, including their own sales channels and third party sales channels.

The products will not be up to standard if they are found.

At the same time, Jingdong will actively cooperate with the relevant manufacturers and departments, and strive to maximize the protection of the interests of consumers.
