On May 7th the FDA updated its Emergency Use Authorization (EAU) for respirators (See Appendix A of the EAU) to include this respirator, therefore as of May 7th this respirator is authorized by the FDA for use by health care personnel when used in accordance with CDC recommendations to prevent wearer to exposure to pathogenic biological airborne particulates resulting from the COVID-19 outbreak.


What is a KN90 respirator, and how should it be used?

KN90 respirators are respirators that meet a China government standard that requires lower filtration efficiency performance (at least 90%) than NIOSH N95 (at least 95%). While KN90 respirators are a form of respiratory protection, the amount of exposure reduction they are designed to provide is lower than the minimum amount that U.S. OSHA and NIOSH associates with the filtering facepiece class of respirators. Therefore, it is recommended that the use of KN90 respirators be considered a Crisis Capacity Strategy and that they be used where masks would otherwise be used, per the CDC prioritization table titled “Suggested facemask or respirator use, based upon distance from a patient with suspected or known COVID-19 and use of source control” in the CDC’s Crisis Capacity Strategies for Optimizing the Supply of N95 Respirators.
