What are the best masks to prevent smog?

1. N95 mask. N95 respirator is used for respiratory protection of some non-oily particles. Its filtration efficiency reaches 95%, which can effectively isolate inhalable particles in the air and prevent various diseases. This kind of mask has small respiratory resistance, is comfortable to wear, can fit the face well when wearing, and is convenient to carry because of its folded design.

2. Activated carbon mask. Activated carbon mask can effectively absorb harmful substances in the air, such as benzene, formaldehyde and other harmful gases, and can be worn after home decoration, but it can not effectively block fine particles.

3. Nano-antibacterial material+superfine fiber filter mask. This kind of mask is attached to the mask fabric by using mature nano-material nano-silver. This kind of nano-silver can be used for disinfection and purification of drinking water, so it also has a strong decomposition and killing effect on micro-pollution particles adsorbed on the mask, such as PM2.5 and bacterial germs. If you have the conditions at home, you can also use an air purifier, and open the window less when there is haze weather.
