Bought for my long stay in China, the respirators. The respirators came in a cardboard box, wrapped individually to. Achieving the PM 2.5 particles often peaks Because food in China, to get especially in winter not around -> Unless someone is their own health at heart. For PM 2.5 particles FFP2 is perfect and filters up to 95% of particulate matter. The mask includes around chin and nose perfectly. What have I to complain about however is that the cardboard box is very thin us thus decays quickly and the individually packaged masks also fast times tearing (packaging). All in all, I recommend the set easily as in Asia often fakes in circulation.
