These masks are complementary to the recommended basic hygiene and social distancing measures, but do not replace them.
These "Comfort" masks therefore cover the face from nose to chin in order to play the role of first barrier to avoid the transmission of particles of oral or nasal origin.
These masks are nasal mouth masks. They cannot be compared to the disposable models FFP2 or FFP3 which are “respiratory” masks intended to filter the air and adapted to high risk areas (where the activity of the virus is proven). On the other hand, these "Comfort" masks can be used as mask covers over an FFP2 or FFP3 in order to be able to wear these disposable masks for longer.
