| KN95 masks are created to have at least 95% filtration efficiency, which makes them just as good as the N95 masks (97% filtration efficiency) and better than surgical masks (95% filtration efficiency) and PM 2.5 filter masks (approximately 60% filtration efficiency). Generally, these masks are considered very effective against airborne particles, viruses, and bacteria, as their efficiency was tested and proven through international regulations and regulatory standards of FDA, CDC, etc. |
