During the COVID-19 crisis, the FDA issued Emergency Use Authorizations (EUAs) that waived certain regulatory requirements and specifically authorized the importation and distribution of specific items listed in the EUA for the uses described in the EUA, so long as the importation, distribution or use of such items fell within the scope of authorization in the EUA. On June 30, 2021 the FDA removed a number of products from the EUA list, including KN95 masks as well as decontamination and bioburden reduction systems to disinfect disposable respirators. This action was taken in response to an increase in domestically-manufactured NIOSH-approved N95s available throughout the country. While the FDA has revoked its EUA for KN95 masks, it does not mean that these respirators are not adequate for consumer use, only that they are no longer appropriate for healthcare workers given the abundant supply of N95 respirators.
