Nanofiber face mask mainly material is nanofiber ,and matched with meltblown cotton,dust-proof cotton,activated carbon materials and flame retardant materials.The effective porosity of the nanofiber material is 0.2-0.3um,the particles larger than the effective pores of the nanofiber can be blocked,has same protective effect on salt medium and oil medium,and long service life.Characteristics:
1.Ultra-fine voids,completely isolated smog and soot exhaust;
2.Physical filtration,no rely on electrostatic adsorption,effective protection for longer;
3.Multi-effect protection PM2.5,Pollen,viruses,bacteria,tail gas,droplets,oily smoke,etc.
