NIOSH Highlights New Notices Regarding Agency-Approved Respirators

NIOSH recently alerted respirator users of three new announcements regarding NIOSH-approved respirators. One announcement concerns respirators formerly manufactured under the brand of Honeywell International Inc., another relates to identification of a composite cylinder from Interspiro, and the last is a notice regarding certain NIOSH respirator approvals.

A notice published in December is related to the recent acquisition of certain Honeywell International business segments by PIP Global Holdings Inc. According to the notice, the NIOSH approval holder for affected respirators formerly manufactured under the Honeywell International brand has been updated from Honeywell to PIP. Users who check NIOSH approval information for these respirators using the agency’s Certified Equipment List will now see PIP as the approval holder. Further information regarding this transition can be found in a letter from PIP (PDF).

Product advice published by the company Interspiro in December concerns the identification of its 45-minute composite cylinder with part number 35689-01, which carries NIOSH approval number TC-13F-0962. Affected cylinders currently have a QR code on their labels that allows users to access the part number and NIOSH approval information. The company says that it plans to update future production of the cylinders so that the part number will be printed directly on the labels. This change is intended to support clear identification of the cylinders’ part number. In the meantime, Interspiro states that the cylinders are safe to use and meet all applicable NIOSH requirements. Additional details can be found in the notice from Interspiro (PDF).

In a notice dated January 2026 (PDF), NIOSH explains that the company RPB Safety LLC has voluntarily rescinded 17 respirator approvals. The rescission affects certain models of supplied-air respirators and powered air-purifying respirators. Respirators bearing the approval numbers listed in NIOSH’s notice are no longer approved by the agency and may no longer be used, manufactured, assembled, sold, or distributed. NIOSH directs individuals to contact RPB Safety for additional information regarding this decision.

Announcements about changes to respirator models’ approval status can be found on NIOSH’s Respiratory Protective Device Info webpage. A separate page on the NIOSH website lists user notices issued by approval holders and industry partners. Respirator users can confirm that a device or component is valid through the NIOSH Certified Equipment List.
