Experts at the University of Massachusetts also confirmed that as a result of prolonged use of the muzzle, its structure is completely deformed.

As a result, the mask loses its protective properties and even becomes dangerous. This is primarily due to the fact that the mask retains the bacteria that filters it.

The other danger is the change in air flow. When the protective equipment is blocked, the air does not begin to pass through the mask, but around it.

According to scientists, this increases the possibility of infection with corona several times, as an environment such as a wet and used mask attracts the bacteria of the coronavirus and is an ideal breeding ground for infection.
