ASTM-rated face masks?

Medical masks have always been an important part of the medical industry and as crucial equipment, they need evaluation and rating.

Based on the situation, you may need to use different types of masks. One of the elements that you need to keep in mind while choosing a mask is the level of fluid exposure in the environment.
The ASTM F2100 rating system offers three levels of medical masks. ASTM Level 1 masks are suitable to use in environments with low levels of fluid exposure, so they will be sufficient for low-risk situations. ASTM Level 2 masks are suggested to be used for average levels of fluid exposure. Level 3 masks give you the highest level of protection from high levels of fluid exposure.
It is of high importance to mention that medical masks can provide you with sufficient protection only if you use proper masks in every environment.
