The mask is the simplest way to protect yourself against viruses. Along with respirators, it has become indispensable and relevant in almost every corner of the world since the beginning of 2020.

Revyuh shows you what the fibers of protective masks look like under a microscope.

There is a popular opinion that a protective mask is an unreliable tool and incapable of saving a person from COVID-19. In the photo: a cross-section of a cotton mask under the microscope.

This opinion is based on the fact that the material used to make the mask is not capable of trapping virus particles. In the photo: fibers of a viscose protective mask under the microscope.

However, it should not be forgotten that the mask is designed to prevent the spread of the virus from its wearer to the environment by droplets in the air. In the photo: cross section of a respirator layer under the microscope.

The virus itself will not be stopped by the mask as the particles are so small that they can easily penetrate the fibers. However, the mask does prevent the saliva particles containing the virus from reaching other people. In the photo: the fibers of a polyester mask under a microscope.

Therefore, there is no doubt about the reliability of protective masks, but it is necessary to use them correctly, that is, change them every 2-3 hours, since, otherwise, the microbes accumulated in the mask can harm health. . In the photo: The fibers of cotton and viscose masks under the microscope.
