3M 60923 vs 60926: OV/AG/P100 vs Multi-Gas/P100 Compared

The 3M 60923 is approved for organic vapor, acid gas (HCl, SO2, Cl2), and P100 particulates. The 3M 60926 extends coverage to include hydrogen fluoride (HF), chlorine dioxide, and additional gases. Both include P100 at 99.97% efficiency.

No. The 3M 60923 does not carry NIOSH approval for hydrogen fluoride. If your workplace involves HF, you need the 3M 60926, which is approved for HF protection.

The 3M 60926 is NIOSH-approved for organic vapor, acid gas (HCl, SO2, Cl2), hydrogen fluoride (HF), chlorine dioxide (ClO2), and P100 particulates. It is the highest-protection combination cartridge in the 3M 60 series.

Use the 3M 60923 when your hazard assessment confirms OV and acid gases (HCl, SO2, Cl2) but no hydrogen fluoride or chlorine dioxide. Chemical plants, wastewater treatment, and battery manufacturing are typical 60923 applications.

Yes, in most cases. Semiconductor fabs involve hydrogen fluoride and other aggressive acid gases not covered by the 60923. The 60926's HF approval makes it the standard choice in semiconductor, photovoltaic, and glass etching facilities.

Yes. Both cartridges use the standard 3M bayonet mount and are compatible with 6000, 6500, and 7500 series half facepieces, plus 6800 and 6900 full facepieces. The mount is identical.

The 3M 60926 typically costs 20–35% more than the 60923 due to additional sorbent layers for HF and broader gas coverage. If HF is not present, the 60923 provides equal OV and acid gas protection at lower cost.

Review the Safety Data Sheets (SDS) for all chemicals in your workspace. If any list hydrogen fluoride, chlorine dioxide, or gases not covered by the 60923, you need the 60926. OSHA 29 CFR 1910.134 requires hazard assessment before cartridge selection.

Yes. The 60926 provides all the protection of the 60923 and more. If your site wants to standardize on one multi-gas cartridge, the 60926 is the more conservative choice. The tradeoff is higher cost per pair.

Life depends on contaminant concentration, temperature, and humidity. Replace when you detect breakthrough odor, when breathing resistance increases, or per your change-out schedule. In high-concentration environments, daily or per-shift replacement may be required.

Yes. Both cartridges fit the 3M 6800 and 6900 full facepiece respirators. Full face respirators are recommended when eye protection from chemical splashes or vapors is also required — especially for HF environments where the 60926 is used.

Per NIOSH/OSHA color-coding conventions, multi-gas cartridges carry a combination color designation. Always verify identification by reading the NIOSH approval number on the cartridge body rather than relying on color alone.
