Can the activated carbon mask prevent particles of PM2.5?

The role of activated carbon mask in life;

The activated carbon in the activated carbon mask can effectively adsorb harmful gases such as benzene and formaldehyde entering the air, but the blocking effect on fine particles is not ideal. As the source of particulate matter, activated carbon itself is likely to be inhaled by the wearer, which will cause harm to people with chronic respiratory diseases or infirmity. Usually, activated carbon masks are mainly used for room decoration, odor removal and deodorization.

What is PM2.5:

Pm is the abbreviation of particulate matter in English, which translates into particulate matter in Chinese. Pm2.5 refers to particles with a diameter less than or equal to 2.5 microns in the atmosphere, sometimes called lung particles. In most cases, our daily smog weather is caused by pm2.5. Although the content of PM2.5 in the atmosphere is very small, it is a veritable invisible killer because of its small mass, long time to carry viruses and harmful substances, diverse transmission channels and long moving distance.

Conclusion: Therefore, the activated carbon mask can not effectively stop pm2.5.

Three effective ways to stop PM2.5;

Brownian motion, screen interception, negative oxygen ion neutralization, precipitation. Eco-level negative oxygen ions can actively capture small particles of dust, make them coagulate and precipitate, and effectively remove air dust of 2.5 microns and below, even particles of 1 micron, thus reducing the harm of pm2.5 to many people's health. The air purification effect of ecological negative oxygen ions is due to the combination of negative ions with bacteria, dust and smoke in the air and splashing into balls to eliminate the harm of PM2.5. Coincidentally, negative ions do Brownian motion in the air, and Brownian motion combined with floating dust week promotes Brownian motion of floating dust and eliminates floating dust. Experiments show that the smaller the floating dust, the easier it is to be precipitated by negative ions. Negative oxygen ions with high concentration and small particle size in the air, the most harmful dust, bacteria, viruses, etc. Below 1um in pm2.5 is almost zero.
