OANY KN95 non-medical respirator face masks feature 4 layers of protection for maximum protection. The layers are made from high-quality non-woven fabric that is hydrophobic and is water/droplet resistant. Hot air blown cotton is soft and ensures comfort while lowering air velocity.
Multiple layers help filter 95.99% of harmful airborne particulates such as dust, chemicals, microbial particles, pollen, smoke, and can reduce exposure to biological substances, such as bacteria and viruses.
