• 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
