NIOSH Intensifies Post-Market Surveillance: 189 Counterfeit Respirator Listings Removed in 2025
Release time:
Nov 12,2025
The National Institute for Occupational Safety and Health (NIOSH) has strengthened its post-market conformity evaluation program to combat counterfeit respirators flooding the marketplace. In 2025, NIOSH investigated 4,163 suspected fraudulent online respirator product listings and successfully removed 189¹.
"Only respirators evaluated by NIOSH that meet the minimum NIOSH requirements are considered to be NIOSH Approved respirators. However, products exist in the marketplace that are not approved by NIOSH. These products may intentionally or unintentionally mislead end users"¹. |
NIOSH conducts respirator product audits annually for every approval holder, including visual inspections, performance testing against Standard Testing Procedures, and evaluation of documentation¹.
