KN95 is a Chinese standard for respirator masks. Similar to the N95 standard, masks must filter 95% or more of particles to meet the KN95 standard. This mask meets those standards. 

For more information, the Centers for Disease Control (CDC) has provided guidance on use of alternatives such as KN95 masks when N95 masks are in short-supply. The CDC also has published testing results for over 120 KN95 masks for you to identify and select the right mask for you. These results indicate which masks met or failed the 95% filtration standard when tested.

The Food and Drug Administration (FDA) has issued an Emergency Use Authorization (EUA) for respirators manufactured in China. This authorization includes a list of KN95 masks that the FDA has authorized for use in healthcare settings by healthcare personnel. These masks help prevent exposure to the coronavirus when used in accordance with CDC recommendations. The FDA removed masks that failed to meet the 95% filtration standard in CDC testing from the FDA EUA list.
