Comfortable wearing can make employees willing to insist on wearing in the workplace and improve work efficiency. Foreign maintenance-free masks do not need to be cleaned or replaced. When the dust cover is saturated or the mask is damaged, it will be discarded. This not only ensures the sanitation of the mask, but also saves the time and energy of workers to maintain the mask. Moreover, many masks use arched shapes to ensure a good fit with the face. It can reserve a certain amount of space in the nose and mouth, and it is comfortable to wear.
