What do I do with an expired respirator?
section_content: In times of increased demand and decreased supply, consideration can be made
to use N95 respirators past their intended shelf life. However, the potential
exists that the respirator will not perform to the requirements for which it
was certified. Over time, components such as the strap and nose bridge may
degrade, which can affect the quality of the fit and seal. Prior to use of N95
respirators, the HCP should inspect the respirator and perform a seal check.
Additionally, expired respirators may potentially no longer meet the
certification requirements set by NIOSH. For further guidance, visit Release

Reviewer feedback on this answer:
Does not directly answer question, only provides semi-relevant information regarding the extending of shelf life of N95 regulators. Answer should have NIOSH identification guidelines.
The answer is irrelevant to the question. It does not provide explanation of how to identify NIOSH-approved respirators and instead is giving information about N95 usage beyond its intended shelf life.

How can I tell if a respirator is NIOSH-approved?
section_content: The NIOSH approval number and approval
label
are key to identifying NIOSH-approved respirators. The NIOSH approval label
can be found on or within the packaging of the respirator or sometimes on the
respirator itself. The required labeling of NIOSH-Approved N95 filtering
facepiece respiratorspdf
icon includes the NIOSH name, the approval number, filter
designations, lot number, and model number to be printed on the respirator.
You can verify that your respirator approvals are valid by checking the NIOSH
Certified Equipment List
(CEL).
