There are two types of masks: surgical masks and respiratory masks. Recently, a protective mask released which was popularized by COVID-19.
We need to know what the differences are and what they mean so that we can defend well against COVID-19.
First of all, protective masks (including surgical masks) are used to prevent the release of infectious agents transmitted from the upper respiratory tract by drops (aerosols), such as saliva or secretions, when the user exhales.
When used correctly, potentially infected people prevent the pollution of surrounding surfaces and the environment.
The surgical barrier or mask does not protect the person wearing the mask from contamination in the air. In other words, wearing a nose mask does not prevent the wearer from contracting COVID-19.
Fortunately, if we all wear face masks, we reduce the chances of pollution. This mask should not be worn for more than 8 hours depending on use.
Second, respirators such as KN95 or FFP2; protect both directions, preventing users from inhaling or exhaling aerosols by filtering.
Unlike nasal masks, the above masks protect the user from airborne infections.
Let's note, that even wearing a protective mask will not protect you from COVID-19. However, it is better to wear a face mask instead of a face shield in public.
