The Face Mask should be worn tightly over the mouth and nose throughout and should be changed when wet so that the protective effect is maintained. As a rule, the mask should be changed daily.
Wash your hands thoroughly before putting on the Face Mask.
Only touch the protective mask when necessary and with clean hands while wearing it. Avoid touching your face with your hands while wearing a mask.
When removing the mask, first loosen the ear loops and then pull the mask off from back to front. Do not touch the front of the mask.
