Anti fog mask contrast analysis

With the increase of air pollution, masks have become a must for major cities in recent years. Then, since the emergence of the word smog, the products, specifications, and models of masks have emerged in an endless stream. How to choose high-quality masks has become the primary issue for the public. In order to allow consumers to better understand and understand how to choose masks, the China Consumers Association will join the Shanghai Consumer Rights Protection Committee, the Anhui Consumers Association, the Chongqing Consumer Rights Protection Committee, and the Ningbo Consumer Protection Committee. The Harbin Consumers Association conducted comparative tests on masks sold on the market. Commissioned the National Labor Safety Products Quality Supervision and Inspection Center (Beijing) to refer to GB2626-2006 "Respiratory Protection Products Self-priming Filter Type Particle Respirator" for testing the relevant performance, filtering effect on sample masks, respiratory resistance, leakage, etc. Compare the protective performance. The test results will be published on the website of the China Consumer Association. In this test, the 3M series dust masks sold by Shenzhen Pengliang Industry & Trade Co., Ltd. stood out and all performances were better than similar products. The results can be found in "The Rational Selection of Face Masks - A Comparative Test of Protective Performance of 37 Face Mask Products".

According to this experiment, it is found that masks on the market are currently confusing and the filtering effects of different brands of masks are very different. The protective effect is often inversely proportional to comfort. Different sales channels and quality of masks are different, and quality and price are not directly proportional.

According to the results of this experiment, Xiao Bian reminds everyone:

1. When purchasing a mask, first of all, look at the mask's production date, protection level, shelf life, implementation standards, and other relevant information;

2. With the economic conditions permitting, choose a mask with a high filter level. Usually daily use will select a mask with a filter effect of more than 95%;

3. Choose masks that fit well with the face: Tests have shown that disposable cups and one-time-folding masks are no better than disposable flat masks and replaceable filter masks.

4. Tests have shown that masks with good protective effect tend to have higher respiratory resistance. People who are concerned about this can choose masks with breathing valves. Of course, the price will be slightly higher. But the effect is good.

5. The price and quality are not directly proportional. Compared to disposable protective masks, replaceable filter masks are not only expensive, but also have less protective performance than disposable masks.
