The KN95 Mask is certified, genuine and made in accordance with industry standards. The 3M N95 is considered the gold standard for respiratory masks for both medical and personal use but, due to lack of availability of supplies during the Coronavirus/COVID-19 crisis, the KN95 Mask is an approved and suitable equivalent according to both 3M and the CDC. Our mask filters up to 95% of non-oily suspended particles of 0.3-micron levels. Importantly, the rounded shape and thicker surface enable our masks to filter fine particles than other masks designed with rectangular designs, which also tend to be thinner and can only filter particles of roughly 10 microns.
