Disposable Blue Protective Face Mask

Product Details

The mask body of the disposable blue protective face 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 air 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 efficient 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 nose clip to make the mask closely fit the face.

Daily protective masks are mainly divided into two categories: dust masks and gas masks.

Dust mask: a mask that has protection against harmful dust aerosols. Dust-proof masks are generally cup-shaped, which can effectively fit the mouth and nose to achieve the effect of dust prevention. Dust masks are usually used to block dust or exhaust gas and cannot filter out germs.

Anti-virus mask: it is a respiratory protection device used to protect respiratory organs from poisonous biological warfare agents and radioactive dust.
