NIOSH Conformity Assessment Letter to Manufacturers										Related Pages
										**Subject:** Updated Information for NIOSH-Approval Holders having Public Health Emergency (PHE) Approvals issued during the COVID-19 Response, and the NIOSH action to obsolete (phase out) these PHE approvals
Supersedes NIOSH CA 2021-1036NIOSH CA 2022-1045
June 2022
SUMMARY
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 reminded PHE approval holders that these approvals are limited and temporary and will be revoked when the COVID-19 public health emergency declaration ends.**
**Because there are adequate supplies of NIOSH-approved respirators in the United States, NIOSH is immediately obsoleting (phasing out) the remaining PHE approvals. Obsoleted respirators are no longer permitted to be manufactured by the approval holder but can continue to be sold, used, and recognized as NIOSH approved until the approval is revoked or rescinded.**
Approval holders may rescind a PHE approval by emailing the NIOSH Approval Program to identify the approval number to be rescinded.
Approval holders may submit a new approval application to obtain a conventional NIOSH approval. An application for a new NIOSH approval must be submitted and approved by NIOSH through the respirator approval process described in 42 CFR Part 84, NIOSH Conformity Assessment Notice NIOSH CA 2021-1034R1, and the NIOSH Standard Application Procedures.
**The table provided below clearly identifies the obsoleted PHE FFRs and PAPRs and the PHE approval holders. Respirator users should also reference the information provided in NIOSH CA 2022-1044 when making decisions about respirator selection and use.**
