In addition to the filtration efficiency of the mask, the closeness between the mask and the face is one of the important factors to determine the use effect of the MASK.

When testing the tightness of the wearer's face, ensure that air can pass through the mask when it is tightly attached to the edge of the face.

N95 masks are one of nine types of particulate dust masks certified by the National Institute for Occupational Safety and Health and are particularly protective. This means that fine dust larger than 0.3 microns, including PM2.5, as well as small dust, bacteria and viruses, can be filtered out.

It means that compared with the inside of the mask, the fine dust and virus larger than 0.3 micron can not pass through the mask, and the filtering effect can reach more than 95%. Masks N90 and N95 are the protection levels in the National mask standard. Different protection levels represent the protection and filtration ability of masks, namely the ability to prevent fine dust, bacteria and viruses.

The filtering ability of N90 is worse than that of N95. This kind of mask of N90, can keep 90 percent of fine dust and so on out of the mask.
