Anti Haze Mask 199 Yuan And 1 Yuan Effect Turned Out To Be The Same.

Here world clothing shoes The small net of hat net introduces the anti haze respirator 199 yuan and 1 yuan effect.

"Anti fog and haze" and "anti PM2.5"... Most of the mask products in the market have the functions of dustproof and anti haze. They have a good filtering effect for PM2.5. The comparative test results released by China Consumers Association showed that only 37 samples of the 9 samples had good haze suppression effect and smooth breathing, accounting for only 24.3% of the total sample size. A 199 yuan mask can be used as a filter for 1 yuan.

Replaceable filter mask is not as effective as disposable.

There are currently two types of masks bought by consumers: one is disposable respirators made of nonwoven materials with filtering properties; the other is replaceable filter cotton masks.

The 37 samples involved in the comparative test involve 28 mask production and distribution enterprises, which basically cover the main brands and varieties sold on the market, the most expensive ones are 199 yuan, and the cheapest ones are only 0.58 yuan. In the experiment, the protective effect of respirator, such as filtration effect, respiratory resistance and leakage performance, were tested.

After testing, 15 samples of the 37 respirator samples had better initial filtration efficiency for particulate matter. The disposable respirator is better than the replaceable filter cotton mask.

The test personnel pointed out that although the filter material of the replaceable filter cotton mask has certain filtration performance to the particulate matter, the filter area is smaller than the overall area of the respirator, and the insertion of the filter will also increase the respiratory resistance. Therefore, some gases will enter the mask through the cotton cloth around the filter, thereby reducing the filtering effect of the mask.

In terms of leakage performance, disposable cup masks and disposable folding masks are better than disposable flat masks and replaceable filter cotton masks. In terms of respiratory resistance, that is, wearing comfort, except for sample with expiratory valve, the sample with low respiratory resistance has low filtration efficiency or high leakage rate.

　　 Price The difference is 198 yuan, the filtering effect is even the same.

In this experiment, the protection effect is divided into five levels, the highest is five stars. Reporters noted that the price of 199 yuan "totobobo" can be replaced by cotton filter rubber mask, and the price is only 1 yuan "Bao Kang powecom" respirator (disposable folding masks), the filtering effect is the same, all Samsung and half. But in terms of respiratory resistance, the mask of 199 yuan is not as comfortable as 1 yuan.

The "Maskin" 617505 respirator, the filtering effect and respiratory resistance of the two tests reached the highest level of 5 stars. This is the only product in the comparative experiment that has double five-star products at a price of only 7.6 yuan.

The Consumers Association said that the replacement of filter cloth masks is not only expensive, but also better than disposable masks. Some samples of knitted fabric masks sold in the market, especially in the small commodity market, can only filter larger particles, and the effect of preventing haze is poor.

　 The anti haze mask bought from shop is not reliable.

Consumers Association's introduction of anti haze masks from online stores and small commodity markets is not reliable. In the comparative experiment, there were 5 types of filtering effect, and the "suitable beauty" respirator was purchased in Amazon mall. "Wei Kang" was purchased in Jingdong mall. "Xue Fei Er" and "snow show" were purchased from the wholesale market of small commodities.

China Consumers Association reminds consumers that different types of respirators should be worn for different environments. For fog and haze weather, when we predict the concentration of particles to reach the level of pollution, we should wear anti fog and haze masks. At present, the mask with better anti fog and haze effect is a disposable cup mask and a disposable folding mask made of non-woven material with filtering effect. Note that these two kinds of masks are not washable and can not be reused. They should be discarded when they feel bad smell or breathe suffocation and replace the new respirators.

When going to a hospital or having an influenza outbreak, it is recommended to wear a qualified "medical respirator" for effective protection. People with respiratory diseases or older people should not wear large respirators. Currently, respirators with respirators can be selected.

Mask identification and execution criteria are too confusing.

According to the existing standard of mask products in China, mask labels generally require product name, trademark, product type, implementation standard, filter material level, name of production enterprise, and some necessary instructions and warnings. However, this comparative test found that the names of the samples were mostly "Moumou", "so and so" respirator and "duer mask". The specifications and models were marked with various sizes, and the size of the mask was marked by the manufacturer's own type. There are no relevant product standards for haze prevention or anti PM2.5 masks, so there are many kinds of standards for the implementation of the sample masks, some of which implement the technical requirements for medical respirators, some of them implement hygienic standards for disposable sanitary products, some implement enterprise standards, and others are NIOSH standards.

" Mask Although small, but related to the health and safety of consumers, the China Consumers Association has suggested that the relevant departments of the state should further standardize the production and sales of mask products, pay close attention to revising and improving relevant standards, constantly improve the quality of products, and provide consumers with excellent protective products.
