Market is difficult to find new national standard masks

Recently, the haze of frequent occurrences has made the public feel like a “wonderland”, and anti-snoring masks have once again become popular items. Starting from the 1st of this month, China's first national standard for protective masks for civilian use, "Daily Protective Mask Technical Specifications" was formally implemented - after wearing a mask, it should be able to reduce the concentration of inhaled PM2.5 to 75 micrograms per cubic meter, and according to Different levels of protective masks are used for air pollution. The Beijing Morning Post reporter recently visited Shangchao and pharmacies and found that masks that implement the new “Regulations” are still very rare on the market. Experts involved in standard setting said that masks that meet the new standards will be on the market after they have been tested. Consumers should not only look at the implementation standards, but also focus on the protection level and select different numbers according to the face type.

Consumers don't know about the new national standard

The reporter recently discovered that in the pharmacies and daily health food stores, the mask has become a hot product and was placed in the door or on the cash register. The kinds of masks, materials, and methods of use that are marked with “anti-fog and haze” function on the outer packaging are different. Non-woven fabrics are mostly disposable masks, and cotton masks can be replaced after cleaning and replacing the filter again. Some masks are also worn. There is an exhalation valve. The price of a bag of masks is usually around 20 to 40 yuan.

Although the national standard for protective respirator masks has been implemented for five days, the standard for the implementation of most masks in Shangchao and online stores visited by reporters is GB 2626-2006. The reporter found out that this mandatory national standard is entitled "Respiratory protective equipment self-priming filter type particulate respirator." The implementation of the new "Specification" of the product has not been seen. Many pharmacy clerk also said that he had never heard of the new standard mask.

The new national standard is more protective

The reporter noted that the GB/T 32610-2016 “Daily Protective Mask Technical Specification” implemented this month is the recommended standard. Is it better than the standard implementation of masks on the market? How do consumers choose masks? In this regard, a reporter from Beijing Morning Post contacted the China Industrial Textiles Association, which participated in the formulation of new standards.

Zhao Yuyu, a senior engineer of the association, said that before this year, China did not have a standard for civil masks in the air pollution environment. At present, the nominal filtering efficiency of masks on the market is 90%-95%. Is this a very high standard? Zhao Xiaoyu said that the protective effect of wearing masks by consumers, and the design mechanism of filtering efficiency and masks, and facial stickers How relevant. "If it is lax with the face, it may cause leakage in the surrounding area and it may not achieve the desired protective effect." Therefore, the new national standard adopts a very intuitive protective performance index: after wearing the mask can reduce the inhaled PM2.5 concentration to Below 75 micrograms per cubic meter, the air quality of the inhaled body after filtering reaches good and above levels.

Expert advice

Choose masks based on degree of protection

Why hasn't there been any masks on the market for selling new standards? Zhao Yuyu said that in order to meet the new standards, some mask companies have already prepared. From the previous detection situation, some companies' products can meet the requirements of the new national standard, and these masks will be seen in the market one after another.

Zhao Yu-yu suggested that when consumers buy masks, they must first look at whether it is implementing a new national standard, and secondly, it must look at its degree of protection. The new standard divides the protection level of the mask from low to high into four levels of D, C, B, and A. For example, class A corresponds to "severe pollution" and is used when the concentration of PM2.5 is less than or equal to 500 micrograms per cubic meter. Grade B corresponds to severe and below pollution and is used when the PM2.5 concentration is less than or equal to 350 micrograms per cubic meter. Consumers can choose different levels of masks according to different air quality. Third, we must use our own face to choose the large, medium, and small numbers of masks.
