Gauze masks use a big mistake, have you committed?


Gauze masks are very familiar to everyone. Before the arrival of winter, everyone will bring a mask early, which can effectively prevent the cold air from irritating the nose, which is especially important for patients with rhinitis. But do you know that in addition to life, workers in special positions will wear gauze masks when they work, just to prevent dust from attacking and injuring the human body. Can the gauze mask be dust-proof?


In fact, gauze masks are not dust-proof. According to experimental tests, ordinary gauze masks are less effective in protecting particles in the air. Because the ordinary gauze mask is a fiber mask, its blocking principle is a mechanical barrier. Through this layer of mechanical barrier, large particles can be blocked, but particles less than 5 microns in diameter can not be blocked. Needless to say PM2.5 particles. For dust-proof dust masks, it is recommended to use professional dust masks to filter dust more than 95%.
