| The anti-leakage design of the mask is to prevent air from being sucked through the gap between the mask and the human face without filtering through the consideration of technical requirements. Air is like water flow, wherever resistance is small, it flows first. When the shape of the mask is not close to the face, the dangerous objects in the air will leak into the airway from the non-closed place. So, even if you choose a mask with the best filter material. Nor can it protect your health. Many foreign regulations and standards stipulate that workers should conduct regular mask adhesion tests. The purpose is to ensure that workers choose a mask of the appropriate size and follow the correct steps to wear the mask.
