Precautions for wearing a FFP3 mask

 

For better protection, try to tighten the elastic band of the mask when wearing it and compress the aluminum tabs on either side of the nose to reduce leakage around it, and it's best to breathe slowly.

The time of wearing should be appropriate. Medical non-woven masks can be used for 6-8 hours and should be replaced in the following cases: difficulty in breathing, torn or destroyed masks.

Discarded masks should not be thrown away freely, otherwise it will cause secondary pollution. Used masks in the general environment should be put in the garbage, and used masks that pollute the environment should be disposed of according to hazardous waste.
