As far as I know, the purchase of a mask package labeled non-sterile means that the mask meets microbiological control standards, that is, it allows a certain amount of bacteria , which is within manageable limits.
Not sterile? It doesn't mean the mask doesn't protect against bacteria!Medical masks include disposable medical masks, medical surgical masks and medical protective masks.
All three types of medical masks have a microbiological indicator requirement, which consists of two scenarios.
One is non-sterile masks (some companies mark ? Non-sterile?) , which meets microbiological control standards, i.e., a certain amount of bacteria is allowed. However, it must be within controllable limits.
The second is a sterilized mask, which does not allow bacteria.
Both non-sterile medical masks and sterilized medical masks are protective, blocking droplets and preventing cross-contamination.
