CE/USFDA Approved 3Q N95 Mask (1 Order Equals 50)
The outer layer of ffp3 type masks often accumulates a lot of dust, bacteria and other pollutants in the outside air, while the inner layer blocks the exhaled bacteria and saliva. Therefore, the two sides cannot be used alternately, or the pollutants from the outer layer will be inhaled into the human body when directly clinging to the face, and become the source of infection. When the mask is not worn, it should be folded and put into a clean envelope, and the side close to the nose and mouth should be folded inward. Never put it into the pocket or hang it on the neck. If ffp3 mask becomes wet by exhaled hot gas or saliva, its function of blocking bacteria will be greatly reduced. Therefore, it is better to prepare several masks at ordinary times, so as to replace them. They should be changed and washed once a day. Wash with boiling water for 5 minutes.
