Air is like water flow, where the resistance is small, it flows first. When the shape of the non-woven mask is not close to the face, dangerous objects in the air will leak into the respiratory tract from the non-close place. Then, even if you choose the mask with the best filter material. Your health is not guaranteed. Many foreign laws and standards require that workers should regularly conduct non-woven mask sealant tests. The purpose is to ensure that workers choose suitable non-woven masks with large and small size and wear masks according to the correct steps.

It is required that the respiratory resistance should be small, the weight should be light, the wearing is sanitary, and the maintenance is convenient. In this way, employees are willing to wear and improve their work efficiency in the workplace. Currently, there is no need to clean or change parts for maintenance-free masks from abroad. When the dust resistance is saturated or the mask is damaged, it will be discarded, this not only guarantees the hygiene of non-woven masks, but also avoids the time and energy for workers to maintain masks. In addition, many masks adopt arch shape, which can not only ensure good fit with the face shape, but also reserve a certain space in the non-woven mask, making it comfortable to wear.
