1. the utility model discloses in, one side of nasal cavity is pressed close to at the gauze mask to first filter layer and second filter layer, mainly play a guard action to the nasal cavity, and third filter layer and the one side that the active carbon layer is close to air department, when outside air carrying PM2.5 enters into the inside of oral cavity cover, the active carbon layer can adsorb PM2.5, adsorb the rear with PM2.5 from the active carbon layer in order to prevent because of respiratory suction, enter the intracavity portion, cause harm, the opposite side surface on active carbon layer has set up the third filter layer, third filter layer and active carbon layer laminating, the active carbon layer adsorbs PM2.5, then the third filter layer plays a jam PM 2.5's effect.

2. The utility model discloses in, the staff if still need wear the gauze mask when the flu, then can tear the viscous band and will lead to the nose and paste the adhesion on the nose, make the nose ventilate, certain work comfort level has been improved, the bridge of the nose strip sets up the inside with the gauze mask, not with skin direct contact, the comfort level when wearing is improved, first filter layer and second filter layer adhesion, third filter layer and activated carbon layer adhesion, improve filtration efficiency under certain circumstances, first filter layer, the second filter layer, the hole that third filter layer and activated carbon layer surface were seted up all is less than 2.5 microns, prevent that PM2.5 from entering the oral cavity, cause harm to people's lung.
