Most Of The Standards For Anti Haze Masks Are Not Reliable.

As a practitioner wearing masks every day, Zhao Chengyuan, a doctor of medicine and a member of the scientific squirrel club, is very fond of masks.

He believes that most people will be more lovely or handsome after wearing masks.

But in fog and haze days, it is not a lovely thing to put on a haze prevention mask. Although the cartoon mask is cute, its protection function is not strong, so is the ordinary gauze mask.

This is because PM2.5 can cause trouble to our health, and these common respirators do not have strong functions to filter harmful particles.

In heavy fog and haze, a message can make people feel a little relaxed: anti haze masks are expected to usher in national standards.

According to authoritative sources, the "daily protective mask technology specification", which has received much attention from consumers, is expected to be released before the end of the year. The national standard of anti haze mask is expected to come out.

Sales increased anti haze mask sampling 5 failed

According to the current scientific research, the greatest threat to human health in the atmosphere is inhalable particulates (PM10) with diameters of less than 10 microns, especially those with diameter below 2.5 microns, which is known as PM2.5.

These particles are small enough to penetrate the human respiratory system barrier to the alveolar system and enter the blood circulation system. If exposed to high concentrations for a long time, the incidence of lung and cardiovascular diseases such as asthma and stroke will increase significantly.

With the frequent occurrence of fog and haze, PM2.5 mask has become a top priority for haze prevention.

Public data show that a domestic anti haze mask production enterprise shipped more than 2 million 500 thousand shipments in December 2013, and even appeared to be out of stock.

On December 5, 2013, 6 and two days, when the fog and haze were most serious in the Yangtze River Delta region, the sales of PM2.5 masks in Tmall flagship store increased explode, sales exceeded 3 million 300 thousand yuan, and sunrise volume exceeded 200 thousand.

The Taobao index showed that the latest 30 days trading index with "anti haze masks" as the key word increased by 1057.1%, up 2089.2% compared with the same period last year.

The largest sales cities are Beijing, Tianjin, Hebei, Heilongjiang and Henan.

According to incomplete statistics, there are more than 100 brands of masks sold by Taobao alone, ranging from 1 yuan to 100 yuan per mask.

People in the industry say that most of the mask that has anti haze function on the market can not achieve the corresponding effect.

The provincial quality supervision departments found that in the early years of this year, a number of spot checks showed that over 5 of the anti haze masks were unqualified and did not achieve the effect of haze prevention.

"PM2.5 protection technology barrier is very high, specifically to the mask, product fabric, filtration performance, design process, breathability and so on, all need professional research and development and repeated testing.

In a short time, it is very difficult to make products that really protect PM2.5. "

The industry said, "many of the original garment factories that are losing money are now working on masks, and professional indicators are definitely not."

Standard missing "dependable" anti haze mask difficult to find

"The purpose of inventing the mask is not to use it as a mask."

Zhao Chengyuan told reporters of "Legal Daily".

It is understood that the so-called "anti haze masks" sold on the market are mainly of three types: gauze mask.

This mask can filter out most of the dust and germs, but has little protection against PM2.5.

The two is activated carbon respirator.

The mask added activated carbon layer with adsorption, but it only played a role in isolating peculiar smell, and it was not effective against particles.

The three is medical masks, including disposable medical masks and N95 respirators.

The disposable disposable medical masks are generally non-woven fabrics, which have the functions of anti droplet and hygroscopicity. However, the effect of filtering particles is not ideal and is not suitable for resisting PM2.5.

In contrast, the N95 mask has better anti haze effect, but it has poor air permeability. It is easy to cause breathing difficulties. For a long time, there will be anoxia and chest tightness. Children with poor respiratory function, elderly people and patients with cardiovascular diseases should not wear long time.

The market of mask with different quality and brand names will inevitably lead to confusion and real damage to consumers. The industry standard of PM2.5 respirators is urgently needed.

A gratifying piece of news is that the standard preparation work of "daily protective mask technical specification" will be held recently, and the standard setting work has been officially launched.

Relevant departments of the state have also opened a green channel to speed up the establishment and approval of the national standard, and have issued the standard number 20140042-T608.

However, the industry estimates that "the introduction of a standard must be strictly controlled, and the fastest way is to 2015".

It is reported that the "daily protective mask technology specification" will cover masks.

Requirements, structural requirements, label identification requirements, appearance requirements, etc., the main indicators include functional indicators of particulate matter filtration efficiency, expiratory suction resistance index, adhesion index and so on.

As a textile, the index also involves formaldehyde content, pH value, microorganisms such as the number of Escherichia coli bacteria, and the total number of fungal colonies.

In addition, the new national standard will also carry on the mask.

And classification.

According to the degree of air pollution, it can be divided into the application of severe pollution, moderate pollution and mild pollution. According to the characteristics of different populations, such as adults, children and infirmity, different respirator resistance indicators are set for classifying masks.

"If it can be established civilian

The standard can effectively prevent the counterfeit and shoddy products and protect the consumer's daily protection.

Insiders said.

According to Zhao Chengyuan, finding a reliable respirator to filter bad air is the most practical and easiest way of personal protection when heavy pollution weather can not be alleviated for a while.

However, before the introduction of the new national standard, it is not easy for consumers to find a reliable mask.
