Which type of facial protection is there?

We differentiate between masks and respirators. Masks are loose fitting covering the nose and mouth. They are designed to protect others (patients) by preventing bodily fluids leaving the wearer. They do not have a safety rating. Masks are not recommended as a protection against COVID-19. Respirators provide a tight fit around nose, mouth and face (half or full face). They use a two-way filter, which protects against infection from others. Such Respirators have a safety rating (NIOSH or FFP).
