For the mask to fulfill its purpose, it must be used correctly. When
wearing, the hygiene mask should adhere tightly to the face - its
protruding fragments may let aerosols through and expose us to possible
infection. After each use, the mask should be disposed of or - if you
use reusable cotton masks - washed at high temperature and ironed. After
removing the protective mask, you should disinfect or wash your hands.
