3M Secure Click D80921 Organic Vapor P100 Cartridge — Combination, HF-800 Series, 1 Pair

3M Secure Click D80921 Organic Vapor P100 Cartridge overview

The 3M Secure Click D80921 Organic Vapor P100 Cartridge is a NIOSH-approved combination cartridge that layers an organic-vapor sorbent with an integrated P100 particulate filter, so a single cartridge handles both solvent-type vapors and airborne particulate. It's built exclusively for the 3M Secure Click platform — the HF-800 series half mask and the FF-800 full facepiece — and clicks into place without tools. Because it targets organic vapor and particulate specifically, it's a common pick for painting, coatings, solvent handling, and similar tasks where the hazard is well-defined. For a full breakdown of the line, see our Secure Click filters & cartridges guide and best cartridges for the HF-800 series.

Cartridge selection is a matching exercise: the D80921 covers organic vapor plus P100 and nothing more. If your exposure assessment names acid gases, ammonia, or formaldehyde, this is the wrong cartridge — those need a different sorbent. Our how to choose a respirator cartridge and how to read a cartridge label references walk through matching contaminants to the right cartridge, and are respirator cartridges universal? explains why Secure Click cartridges only fit Secure Click masks.

Where the D80921 fits

The D80921 shines wherever the hazard is organic vapor plus particulate. For solvent-based painting and coatings, the organic-vapor sorbent and P100 layer together catch vapor and overspray — our best 3M cartridge for spray paint guide walks through the paint-booth scenario. It's equally at home in solvent handling and degreasing; cross-check your specific chemicals against best 3M cartridge for solvents before committing.

For adhesives, resins, and coatings prep, one combination cartridge replaces the hassle of stacking a separate particulate filter onto a gas cartridge. And in dusty work that also carries solvent vapor, you still get true P100 filtration (≥99.97%, oil-resistant) on the particulate side — the same class as a dedicated P100 filter.

Frequently asked questions

What does the 3M Secure Click D80921 cartridge protect against?

The D80921 is a NIOSH-approved combination cartridge for certain organic vapors plus P100 particulate (oil and non-oil aerosols, 99.97% efficient). It does not protect against acid gases, ammonia, formaldehyde, or carbon monoxide.

Which respirators does the D80921 fit?

Only 3M Secure Click facepieces — the HF-800 series half masks and the FF-800 series full facepiece. The Secure Click connection is not interchangeable with 3M bayonet (6000/7500) systems.

Is the D80921 the same as the D80923 or D80926?

No. The D80921 is organic vapor plus P100 only. The D80923 adds acid-gas protection (OV/AG), and the D80926 is a multi-gas/vapor P100 cartridge that also covers gases such as ammonia and formaldehyde. Match the cartridge to the contaminants named in your exposure assessment.

What does "combination cartridge" mean on the D80921?

It combines a gas/vapor sorbent layer (for organic vapors) with an integrated P100 particulate filter in one cartridge, so you get vapor and particulate protection without stacking a separate filter.

How many cartridges are in a D80921 pair, and do I need one or two?

One pair equals two cartridges. Secure Click half and full facepieces use two cartridges at once — the dual-flow design creates four airflow paths for easier breathing — so a pair equips one respirator.

Can the D80921 be used for spray painting or working with solvents?

Organic-vapor protection covers many solvent vapors found in paints, thinners, and adhesives, which is a common use for this cartridge. Confirm the specific chemicals against the manufacturer's selection guidance and your safety data sheets before relying on it, and pair it with proper ventilation.

Does the D80921 protect against acid gases or ammonia?

No. The D80921 is organic vapor plus P100 only. For acid gases choose the D80923 (OV/AG); for ammonia, methylamine, or formaldehyde choose the multi-gas D80926. Using the wrong cartridge offers no protection against those contaminants.

What is the P100 rating on the D80921?

P100 is the highest NIOSH particulate class — at least 99.97% filtration efficiency and strongly resistant to oil. The integrated P100 layer captures dusts, mists, fumes, and other particulates alongside the organic-vapor sorbent.

When should I replace the D80921 cartridge?

Follow a change-out schedule based on your exposure, plus manufacturer guidance. Replace organic-vapor cartridges if you detect odor, taste, or irritation (breakthrough), and replace the particulate side when breathing resistance increases. In oil-aerosol environments, 3M specifies replacement after 40 hours of use or 30 days, whichever comes first.

Can I use the D80921 in a confined or low-oxygen space?

No. An air-purifying cartridge cannot add oxygen and is not for low-oxygen or immediately dangerous atmospheres. Those conditions require a supplied-air or self-contained air system selected by a qualified person under your respiratory protection program.

How does the Secure Click connection work on the D80921?

You align the cartridge with the facepiece port and push until it clicks. The design gives positive, tool-free attachment and a built-in seal path; the push-button seal-check on HF-800 masks lets you verify the facepiece fit quickly.

Does the D80921 include the HF-800 respirator?

No. The D80921 is the cartridge pair only. You need a compatible 3M Secure Click HF-800 half mask or FF-800 full facepiece, sold separately, to use it.

Is the D80921 NIOSH-approved, and how do I confirm the seal?

Yes — it is NIOSH-approved as part of an approved Secure Click assembly. NIOSH approval applies to the complete facepiece-and-cartridge combination, so use only approved pairings. Perform a user seal check every time you don the respirator, and fit-test per your program before first use.
