Contact me, I am a direct distributor of KN 95 masks with exhalation valve.
Less risk of hypoxia, greater comfort, you can use it for long periods, it reduces the discomfort that leads many to settle or get tired of using it.
I sell them by box (20) or individually. Each comes individually packaged for reliability.
Cuenca.
