3M Secure Click D80926 Multi-Gas/Vapor P100 Combination Cartridge, 1 Pair

Read our hands-on 3M Secure Click D80926 review for field-tested buyer notes.

3M Secure Click D80926 Overview

The 3M Secure Click D80926 is a NIOSH-approved multi-gas/vapor P100 combination cartridge that provides simultaneous protection against organic vapors, acid gases (Cl₂, HCl, SO₂, HF), ammonia, methylamine, formaldehyde, and P100 particulate (≥99.97% at 0.3 µm). It is sold as a 1-pair set and mounts via the Secure Click half-turn bayonet onto 3M HF-800 series half-facepiece respirators and FF-800 series full-facepiece respirators only.

This is a soft-housing combination cartridge — not a hard-shell filter — and it is the widest-coverage option in the Secure Click D80xxx combination series. It is the correct choice when your work environment involves multiple simultaneous chemical hazards: for hazard-assessment context, the how to choose a respirator cartridge guide and the 3M filter and cartridge guide both walk through the decision logic. For cartridge color coding, see the respirator cartridge color chart. Browse the full lineup in the 3M respirator filters and cartridges collection.

Where the D80926 Fits in Respirator Selection

Combination cartridges serve mixed-hazard environments where a single gas/vapor cartridge would leave you exposed to particulate, or a particulate-only filter would leave you exposed to chemical gases. The D80926 addresses the broadest chemical scope in the Secure Click combination range.

• OV + P100 only (no acid gas, ammonia, formaldehyde) → the D80921 is sufficient and typically lower-cost.
• OV + Acid Gas + P100 (without ammonia/formaldehyde) → consider the D80923.
• Multi-gas + P100 (OV, acid gas, ammonia, formaldehyde) → the D80926 is the right choice. Read organic vapor vs P100 and respirator filter types explained to confirm your hazard class.
• Gas-only, no particulate hazard → the gas-only D8006 multi-gas cartridge without P100 filtration.
• 3M bayonet respirator instead of Secure Click → Secure Click cartridges will not physically fit; you need a bayonet-mount cartridge in the 3M 6000 or 7093 series.

Who Should Buy the 3M Secure Click D80926?

Buy the D80926 if you run a 3M HF-800 or FF-800 Secure Click respirator and your hazard assessment identifies simultaneous exposure to organic vapors, acid gases (including HF, SO₂, HCl, or Cl₂), ammonia, methylamine, or formaldehyde — and particulate is also present.

Choose a different cartridge if:

• Your only gas hazard is organic vapor (no acid gas, ammonia, formaldehyde) → the D80921 (OV/P100) is narrower and lower-cost.
• You need OV + acid gas + P100 but not ammonia/formaldehyde → the D80923 (OV/AG/P100).
• Your hazard is gas-only, no particulate → the D8006 multi-gas cartridge.
• Your hazard is particulate-only → the D3091 P100 filter.
• You run a 3M bayonet respirator → Secure Click cartridges will not fit; use a bayonet-mount option instead.

What Does the D80926 Protect Against?

What the D80926 Does NOT Protect Against

• Carbon monoxide (CO)
• Nitrogen dioxide (NO₂)
• Hydrogen cyanide (HCN)
• Oxygen deficiency
• Unknown / unidentified atmospheres
• IDLH (immediately dangerous to life or health) conditions
• Chemical warfare agents
• Radioactive particulate (requires specialized protection)

Safety: The D80926 is an air-purifying cartridge — it removes contaminants from ambient air but does not supply or add oxygen. It must not be used in oxygen-deficient, unknown, or IDLH atmospheres; those conditions require supplied-air respirators or SCBA as specified by a qualified safety professional per OSHA 29 CFR 1910.134. Always conduct a hazard assessment before cartridge selection and change cartridges on a schedule determined by your respiratory protection program.

Best Applications for the D80926

Chemical Processing & Petrochemical Plants

Environments where workers encounter organic vapors, acid gases, and particulate simultaneously — such as reactor cleaning, maintenance on chemical lines, or loading operations — are exactly the multi-hazard scenario the D80926 is built for. Its P100 filtration also captures incidental dust and catalyst fines. See P100 respirator filters for related options.

Wastewater Treatment & Utilities

Wastewater environments often involve ammonia, hydrogen sulfide (check your specific hazard), chlorine, and airborne particulate together. The D80926 addresses ammonia, Cl₂, acid gas, and P100 particulate in a single cartridge, reducing the need for specialized single-gas units. Compare the multi-gas gas-only option — the D8006 — if no particulate is present.

Paint Stripping, Coating, & Surface Finishing

Paint stripping with chemical agents releases organic vapor and may involve acid compounds, while sanding generates respirable particulate. The D80926 covers both hazard streams. For pure particulate work — when no chemical gas is present — the D3091 P100 filter is sufficient and lower-cost.

Lab & Formaldehyde-Exposure Environments

Laboratories, histology, embalming, and resin manufacturing expose workers to formaldehyde — a hazard not covered by standard OV-only cartridges. The D80926 includes formaldehyde in its protection scope. Read respirator filter types explained to understand how the media layers work together.

Welding & Metal Fabrication with Chemical Exposure

Heavy welding fume requires P100 particulate filtration — a standard documented in guidance from bodies such as AIHA. When the welding environment also involves solvent degreasers or acid flux, the D80926's combination coverage eliminates the need for a dedicated chemical cartridge on top of a particulate filter. For welding-specific guidance, see best respirator for welding fumes.

3M Secure Click D80926 Pros & Cons

Compatible 3M Respirators

The D80926 uses the 3M Secure Click half-turn bayonet mount. It is compatible only with the Secure Click platform and will not physically attach to any 3M standard-bayonet respirator:

Important: Secure Click cartridges are not interchangeable with 3M standard-bayonet cartridges and filters. The Secure Click half-turn mechanism is physically distinct. Browse compatible respirators in the 3M half-face respirators and 3M full-face respirators collections.

D80926 vs Other 3M Secure Click Combination Cartridges

D80926 vs D80921 (OV/P100)

The D80921 covers organic vapor plus P100 particulate. It does not address acid gases, HF, ammonia, or formaldehyde. If your hazard assessment includes any of those additional gases, the D80926 is required. If your hazard is OV and particulate only, the D80921 is the more targeted and typically lower-cost option.

D80926 vs D80923 (OV/AG/P100)

The D80923 covers organic vapor, acid gas, and P100 particulate — but not ammonia, methylamine, or formaldehyde. Choose the D80926 when your environment includes those additional hazards (wastewater, labs, HVAC refrigerant work); choose the D80923 when acid gas coverage is sufficient.

D80926 vs D8006 (Multi-Gas, No Particulate)

The D8006 is a gas-only multi-gas cartridge — same broad chemical scope but with no particulate filtration layer. When dust, mist, or fume is present alongside chemical hazards, the D80926 is the correct choice. When your environment is gas-only with no airborne particulate, the D8006 is simpler and avoids particulate-filter breathing resistance you don't need.

3M Secure Click D80926 Frequently Asked Questions

What is the 3M D80926 used for?

The D80926 is used in multi-hazard environments where workers face simultaneous exposure to organic vapors, acid gases, ammonia, formaldehyde, and respirable particulate. Typical applications include chemical processing, wastewater treatment, paint stripping, laboratory work, and welding in contaminated environments.

Does the D80926 fit a 3M 6000 series respirator?

No. The D80926 uses the Secure Click half-turn bayonet mount and is physically incompatible with the 3M standard bayonet used on 6000, 6500QL, 7500, 7800S, and FF-400 respirators. It will only attach to HF-800 and FF-800 Secure Click respirators.

Is the D80926 a P100 combination cartridge?

Yes. The D80926 includes a P100 particulate layer (≥99.97% efficiency at 0.3 µm, oil-proof) combined with multi-gas chemical protection. This makes it a combination cartridge, not a gas-only cartridge or a particulate-only filter.

What acid gases does the D80926 protect against?

The D80926 protects against chlorine (Cl₂), hydrogen chloride (HCl), sulfur dioxide (SO₂), and hydrogen fluoride (HF), all within its acid gas protection scope.

Does the D80926 protect against hydrogen fluoride (HF)?

Yes. Hydrogen fluoride is included within the acid gas protection range of the D80926. For HF-specific particulate protection in a hard-shell filter format, see the D9093C P100 HF hard-case filter.

What is the difference between the D80926 and D80921?

The D80921 covers organic vapor and P100 particulate only. The D80926 extends that coverage to add acid gases (Cl₂, HCl, SO₂, HF), ammonia, methylamine, and formaldehyde. If your hazard assessment identifies only OV + particulate, the D80921 is the correct and typically lower-cost choice.

How many cartridges are in a D80926 package?

The D80926 is sold as 1 pair, meaning two cartridges per order — one for the left side and one for the right side of the respirator.

Can I use the D80926 on a 3M HF-801 respirator?

Yes. The HF-801, HF-802, and HF-803 are all half-facepiece Secure Click respirators and are compatible with the D80926's Secure Click half-turn mount.

Does the D80926 protect against silica dust?

Yes. The P100 particulate component of the D80926 captures ≥99.97% of airborne particles at 0.3 µm, which covers respirable crystalline silica. For silica-specific guidance see best respirator for silica dust.

When should I replace the D80926?

Replace the D80926 according to your employer's written change-out schedule under OSHA 29 CFR 1910.134. Replace immediately if the cartridge is damaged or deformed, or if you detect chemical odor or taste while wearing it — either indicates the sorbent is saturated or the seal has been compromised.

Is the D80926 suitable for use in IDLH atmospheres?

No. The D80926 is an air-purifying respirator cartridge and must not be used in IDLH (immediately dangerous to life or health) atmospheres, oxygen-deficient environments, or unknown chemical atmospheres. Those conditions require supplied-air respirators or SCBA.

Can I pair the D80926 with a full-face respirator?

Yes. The D80926 is compatible with the 3M FF-800 series full-facepiece Secure Click respirators, which provide an assigned protection factor (APF) of 50 — five times the APF of a half-facepiece unit.

Does the D80926 protect against welding fumes?

The P100 layer captures respirable metallic particulate from welding fume. If your welding environment also involves solvent degreasers, acid flux, or other chemical vapors, the D80926's combination coverage addresses both streams. For weld fume-only work with a Secure Click respirator, the D3091 P100 filter is a simpler and lower-cost option.
