Now that there are too many products in the name of anti-fog and haze, I have seen more than 300 yuan in one mask, but in the end there is an effect?” This morning, Wang Jianmin, a Beijing Municipal People’s Congress representative and a professor at the Beijing Normal University’s School of Management, reported to the local people’s congress. He disclosed to reporters the issues that the conference will focus on.

Some time ago, Beijing suffered continuous heavy pollution and caused various anti-haze products to sell well. Wang Jianmin said that light fog masks make consumers have no choice but that prices range from a few bucks to several hundred bucks, but which kind of effective consumers are not clear.

"I see more than 300 masks on the Internet. The price of purifiers is getting higher and higher. Recently, people have begun to install new air systems." He believes that such a wide range of anti-fog products requires a unified evaluation standard. Publicized for the common people’s choice. He suggested that relevant government departments should lead the development of standards and that third-party agencies should test and publish the results. At the same time, the Beijing Municipal Government should also cultivate local enterprises to produce protective products so that a wider range of citizens can enjoy cheap and effective anti-fog and smog masks and other products.
