Disposable masks are made of more than three layers of 28 grams of non-woven fabric; the bridge of the nose is made of environmentally friendly plastic strips, which do not contain any metal, and are breathable. They are comfortable and especially suitable for electronic factories and daily use. Disposable masks (medical surgical masks) can prevent respiratory infections to a certain extent, but cannot prevent haze. Pay attention when buying, you should choose a mask with the words "Medical Surgical Mask" clearly marked on the outer packaging。
