Use electrostatic adsorption filtration technology
The VFE (Virus Filtration Rate) reaches 99% or above, and the particle size is 0.1 to 5 microns.
The BFE (bacterial filtration rate) of the mask filter layer is as high as 99%, which can effectively filter pollen, fly, air pollutants and other molecules with a diameter of 3 microns
The PFE (fine particle filtration rate) of the mask filter layer is also as high as 99%, which can effectively filter particles with a diameter of only 0.1 microns
Passed ASTM F2100-19 Level 2 verification
Adopt alloy (galvanized iron) nose strip, which is closer to the face
The connecting position of the ear rope adopts ultrasonic welding technology, which can withstand a tensile force of 1000 grams and is not easy to place
