Easy Breathing and Cool Black Mask
I have tried many different high protection level masks including N95 and KF94 Masks. Although they are known to provide good protection, these are all very difficult to breath with moisture and heat building up very soon.
This new Nano Mask I first tried last week, is extremely easy to breath. My face comfortably stay dry and cool even after long hours of wearing for my work in the high risk area.
Love the Cool Black Color and Fashion design, so I can wear it for my daily activities also.
