NIOSH Conformity Assessment Letter to Manufacturers
NIOSH CA 2023-1058
May 16, 2023
Between May and November 2020, NIOSH issued limited, temporary Public Health Emergency (PHE) approvals for N95® filtering facepiece respirators (FFRs) and powered air-purifying respirators (PAPRs) to address supply shortages during that time. In July 2021, NIOSH published NIOSH CA 2021-1036 to remind PHE approval holders that these approvals are limited and temporary and will be revoked when the COVID-19 public health emergency declaration ends. In June 2022, NIOSH published NIOSH CA 2022-1044 and NIOSH CA 2022-1045, which obsoleted the remaining PHE approvals and advised users to phase-out the use of these respirators. HHS Secretary Xavier Becerra issued a Statement on the End of the COVID-19 Public Health Emergency on May 11, 2023. May 11, 2023, marked the end of the U.S. federal COVID-19 PHE declaration.
Effectively immediately, NIOSH revokes eight PHE FFR approvals and four PHE PAPR approvals issued to the PHE approval holders listed in the table, below. These respirators are NO LONGER recognized as NIOSH Approved® respirators and therefore cannot be used, manufactured, sold, or distributed. Respirators bearing the NIOSH approval numbers listed below are no longer considered approved and may not be used in fulfillment of any standard or statute requiring the use of a NIOSH Approved respirator.
