People often say that the N95 type mask refers to a mask with a protection level of N95, that is, under the testing conditions specified in the NIOSH standard, the mask filter material is resistant to non-oily particles (such as dust, acid mist, paint mist, microorganisms, etc.) The filtration efficiency reaches 95%. N95 is not a specific product name. As long as it meets the N95 standard and passes the NIOSH review, it can be called "N95 mask". N95 is an American standard, and KN95 is a Chinese standard. "N" stands for non-oily particles, and "95" means that the minimum protection level reaches 95%. Both N95 and KN95 can provide better protection in daily life.
Masks are classified into the following categories according to their functions:
1. Disposable medical masks:
Refers to masks that meet the relevant registered product standards and generally lack filtration efficiency requirements for particles and bacteria.
