Protective Mask
The mask body of the daily protective mask is made of filter material. The wearer overcomes the resistance of the filter material to the airflow by self-breathing, so it is called a self-priming filter respirator. When inhaling, the low air pressure in the mask causes the airflow to enter the mask; when exhaling, the air pressure in the mask is higher than the ambient pressure, and the airflow is discharged through the mask. When the filter material of the mask meets the requirements of the standard, and the mask is close enough to the user's face, most of the inspiratory airflow will be filtered by the filter material. Daily protective masks cannot be 100% close to the face, which is affected by many factors such as face shape, skin smoothness and whether there is a hair pad under the mask. Most of the particulate matter inhaled by wearing a daily protective mask comes from leakage, so the tightness of the daily protective mask is the key to ensuring the effective filter material works. In order to reduce leakage, the daily protective mask must be designed into a body structure, and a certain pressure is applied by the headband and the nose clip to make the mask closely fit the face.
