If you need a mask this is a decent mask, comfortable enough. You can wear it for hours. But this is not an N-95 mask. It doesn't offer the ability to adjust it to fit "snugly" to the face like an N95 mask should. It doesn't offer the true protection that an N95 mask could offer. At best, it has a "loose" fit. As a doctor/surgeon I know this. This is comparable to the protection offered by traditional surgical masks instead of N95 masks. The cost of regular surgical masks is about $10 for 50 masks in normal times. $20 for 50 masks in times of Covid-19. I'm pretty sure Chinese regulators won't allow it to be sold in China as an N-95 mask or the Chinese equivalent of KN95. Revain limits purchases to "medicalβ facilities. it's a limitation. It's more of a mask for a walk in the park than anything else.
