For example, two widely spread experiments have drawn two diametrically opposite conclusions: one said that activated carbon had the best effect, and the other said that activated carbon masks were totally unreliable.
Not only that, for some experiments, using toner or thread incense instead of PM2. This makes the dazzled consumers once again fall into the mystery of the constant chaos. Very general. While affirming this statement, Zhang Caiqing also pointed out: 'In the smog, there are not only particles, but also harmful gases such as hydrogen sulfide.' Zhang Caiqing said that N95 masks are only worn by medical staff during the period of avian flu and SARS.' Ms. It can only be said that it is slightly better than a few dollars. Activated carbon can indeed adsorb some gases, but once saturated, it can no longer continue to absorb, and cannot rely on activated carbon to resist PM2. Zhang Caiqing, director of the Department of Respiratory Medicine, Qianfoshan Hospital, Shandong Province, said that these experiments are limited by experimental conditions and experimental methods, and the results may not be credible.5,
Zhang Caiqing also pointed out that the data thus obtained is not scientific. And various experiments on the Internet seem to be difficult to get a convincing result.' Wang Yan introduced that activated carbon does have Adsorption effect, but mainly for odorous gas, and PM2.Whether the anti-fog masks are effective is a big question for consumers. From the perspective of activated carbon alone, Wang Yan, a professor at the School of Environmental Science and Engineering of Shandong University, said: 'Activated carbon masks may have certain effects, but the use of activated carbon to prevent PM2. At the same time, for another popular choice 'N95 mask', Zhang Caiqing is not recommended.5.
The reporter KN95 respirator manufacturers also found in the standard of 'Ordinary Absorbent Gauze Masks' that it is necessary to use the prescribed measuring tools and test methods to detect whether the different parameters meet the standard. 'The effect is quite limited. 'The elderly, children, pregnant women are not suitable for wearing. But it is not as simple as using a simple instrument to get a convincing answer like in a popular experiment
