It is KF94 standard and FDA (U.S. Food and Drug Administration) certified.
The special 4-layer filter with a 3D structure makes it easy to breathe and boasts a dust collection rate of 99%.
The three-dimensional design ensures a snug fit, and while it is designed to prevent gaps from forming between the mask and your face, there is still room around the mouth, making it less likely to get makeup such as lipstick on it, and your glasses will not fog up easily.
The soft rubber makes it easy to breathe and doesn't hurt your ears, so you can wear them all day without any stress.
Tested to have PFE (fine particle collection efficiency), BFE (bacterial droplet collection efficiency), and VFE (viral droplet collection efficiency) of 99 or more. Quantity: 1 box (10 sheets)
