In addition to the special anti-haze Fold Mask
Marking different features of the Fold Mask, in addition to the price gap, the main technical indicators are also different. Reporters noted that the sales of the network on the face of the implementation of the "respiratory protection products self-absorption filter anti-particulate respirator" industrial Fold Mask standards, and some implementation of the "medical protection Fold Mask technical requirements" and "medical surgical Fold Mask" Medical product standards, there are some Fold Mask manufacturers in Europe and the United States to implement the production standards, and even some do not mark the production standards used.
According to the consumer's reply can also be seen, for the Fold Mask of the anti-haze anti-PM2.5 effect, most consumers can only use the feeling to judge, what can play a big effect, the buyer is not very clear.
Reporters learned that although many Fold Mask in the packaging prominently marked "filter efficiency", but there have been media reports, the relevant departments known as "removal rate of up to 90% or more" Fold Mask for testing, the actual removal rate of only 30% To 40%. According to the Shanghai Quality Supervision Bureau disclosed in March this year, for the production enterprises from Shanghai, the physical sales shops and shop shop 69 batches of samples tested found that 54 batches of mask the minimum filter efficiency of less than 90%, 28 batches The Fold Mask contains carcinogenic formaldehyde.
Civilian Fold Mask special standards released
Fog haze weather, consumers buy Fold Mask, most hope is to dustproof haze, to reduce the inhalation PM2.5 purpose, but the daily use of people in the Fold Mask, is the reference to industrial or medical standards, Do not meet their own needs, coupled with the Fold Mask market logo confusion, there is no uniform evaluation criteria, to consumers pick out the problem.
In this regard, in March last year, Jiangsu Province Special Defense Center jointly China Textile Industry Association organized a standard project discussion, then participated in China's first civil protective Fold Mask national standard set up. November 1 this year, China's first civil protective Fold Mask national standard - "daily protective Fold Mask technical specifications" formally implemented.

For example, D-level Fold Mask for air quality and the following moderate pollution, PM2.5 concentration ≤ 150 micrograms per cubic meter; the opposite A-level Fold Mask for air pollution is extremely serious, PM2.5 concentration of 500 micrograms per cubic M when used. At the same time, the protective effect of Fold Mask are also different, from D to A level, the protective effect was not less than 65%, 75%, 85%, 90%. According to the national standard, consumers in accordance with the standard selection of suitable protective Fold Mask to wear, the inhaled air quality index must be better than the above.
The new national standard under the fold how to buy a mask?
Compared to the previous fold mask GB, the new national standard is facing the use of the crowd is in addition to children, infants and young children outside the ordinary people. So, with the daily protective Fold Mask specifications, many people want to know how to select the Fold Mask.

In this regard, China Industry Textile Industry Association, Senior Engineer of Science and Technology Development Zhao Jinyu pointed out that the characteristics of the Fold Mask itself, with a brand of Fold Mask, with the improvement of protective performance, comfort will be reduced. "If the respiratory resistance is too large, do not rule out the chest tightness, dizziness," she said, so should also be based on the weather and their own situation, wearing the appropriate protective effect of the Fold Mask, do a moderate protection.
In addition to the special anti-haze Fold Mask, there are cotton cloth Fold Mask, disposable medical Fold Mask and so on.
