Review on Respirator Mask Vega KN95 FFP2 with exhalation valve white, 10 pcs by Boyan Borissov ᠌

It should be borne in mind that if a mask is purchased to protect people from a modern disease, then it must be bought without a valve. Different pros: The respirator mask is made normally, "does not fluff" from the time of wear. Different cons: The difference between a mask with a valve and without a valve was not noticed by me. It fogs up the same way, I don’t see a difference in breathing relief. Whatever the mask, but if you walk a couple of flights up the stairs in it, you suffocate.
