Protection
These masks are intended for single use. They do not protect the wearer from aerosols in the air, but protect the environment from any pathogens that the wearer would spread. They also protect the wearer from droplet infections from the saliva of other people and from infections via the mucous membrane of the mouth or nose through touch. However, they do not protect against smaller particles.
