From the anti-microbial point of view, the best choice is a compliant, non-breathing valve medical protective mask(PP Melt Blown Non Woven Vendor) (N95/KN95 mask).

Medical protective masks with high protection levels have better protective effects, but due to the high level of filter material, good adhesion, and higher respiratory resistance, wearing them for a long time will increase the respiratory burden and cause breathing difficulties and other discomforts.

If it is only for daily use and does not go to a place where the risk of pathogen infection is high, such as a hospital, you can choose a medical surgical mask(Meltblown Layer Company).

The standard YY0469-2011 for medical surgical masks also has clear requirements for bacterial filtration efficiency and particle filtration efficiency. Although it cannot effectively block aerosols, it can effectively block the spread of droplets, which is sufficient as a daily protection.

Compliant products will clearly print the corresponding standard number on the package. The standard used for N95 is NIOSH, the standard used for KN95 masks(Cloth Face Mask Factory) is GB2626-2006, the standard used for medical surgical masks is YY0469-2011, and the standard used for medical protective masks is GB 19083-2010, just look at the standard words on the package when purchasing.

In addition to choosing the right mask, you must also use the right mask. Pay attention to the way of wearing and the time of use. Read the wearing method on the package carefully, and confirm the air tightness after wearing them. If you wear glasses and there is fog on the lenses, it must be that the mask is not worn properly.
