Description
KF94 3M 9013 Mask with 94% Filtration Efficiency – KF94 standard mask, this head-worn type has a hook that specializes in filtering fine dust up to 94% efficiency
*Difference between a regular mask and a standard mask
For regular masks (Mask): Prevent the wearer from releasing pathogens into the air -> protect others. Tightness: There is a gap, the breathing air is mainly in and out according to the gap between the mask and the face. Ordinary masks do not hug the face tightly; with gaps, used in environments with low risk of disease transmission, low dust. Administered and approved as a conventional medical supply.
For standard masks: Helps the wearer avoid the risk of exposure to airborne pathogens -> protects the wearer himself. Tightness: Fits the face tightly, there is no gap between the mask and the face -> the air passes through the filter layer. Standard masks can filter fine dust – super fine dust – bacteria – viruses. Designed to fit most faces, no gaps, must meet tight fitting standards.
Used in environments with lots of fine dust and airborne pathogens. CDC guidelines prove that the N95, KF94, KN95 mask lines prevent exposure to bacteria and viruses
