In addition to N95 standard, there is also a GB Model for normal N95 masks. The N95 mask can be tested for authenticity from the packaging seal, wearing comfort and the tightness of the mask. The N95 mask can be used for a long time. There is an obvious N95 mark on the mask, which is comfortable to wear. A total of four layers of materials have very strong tightness. N95 masks are generally made of four layers: electrostatic cotton layer, non-woven cloth layer, TP melt blown layer and clean water non-woven cloth. The respirator has strong respiratory resistance.
