Is it necessary to wear a gas mask for air pollution?

Gas mask is a kind of professional special labor protection articles, which can protect toxic gases such as ammonia and hydrogen sulfide by replacing different filter components. Gas masks are generally used in special working environments such as chemical production protection and petroleum processing. For daily air pollution, because air pollution is mostly caused by suspended particles, not pure toxic gas molecular atoms, the absorption effect of gas mask canister on suspended particles is average. In addition, the chemical catalyst will not react with particulate matter, so it can not play a good filtering role. Therefore, the use of gas masks in daily air pollution will not have a good effect, and the use of high-grade gas masks is expensive and wastes resources.

To protect against daily air pollution, just wear a protective mask. Note that the protective mask here is not an ordinary mask. It is recommended to go to a regular labor insurance store to buy. Before buying, ask if you can protect pm2.5.
