Different masks are important - different masks are needed during a pandemic. I already wrote about the TricoTex bandage-mask. For testing, we bought several different masks with the hope that some would be suitable for the child. Although they say that children can go without masks. Well, I don’t know, we sometimes put on a mask for the baby when we visit especially crowded places. This household mask is KN95. Made in China. The mask says that the filtration efficiency is 95%. In my opinion, this is a pretty good indicator. The packaging of the mask shows how to properly put on the mask. This mask is for adults. The mask uses non-woven filter material. The mask is fixed on the nose with a metal clip. The mask looks very good. The supplier of masks to Russia is EVA LLC. We use. True, they did not find anywhere how long you can use this mask.
