Maybe you missed the post I replied to? Hospitals--high risk places-- often require that people wear a hospital-supplied mask because they know that people like you (and I) are not qualified to identify good masks.

There are no experts who accept unrated all cotton masks such as the ones you posted. People should buy N95, KN95, or KF94 masks; and make sure they fit snugly
