3M D8001 vs D80921: Secure Click OV vs OV/P100 (2026)
Quick Verdict
Reviewed by the WC Safety Editorial Team — Last updated: June 2026.
The 3M D8001 (vendor: 3M, SKU D8001) and the 3M D80921 (vendor: 3M, SKU D80921) are both 3M Secure Click cartridges for the HF-800 and FF-800 respirators. The 3M D8001 provides organic vapor only; the 3M D80921 provides organic vapor with P100 particulate. The D80921 adds a P100 particulate filter to the same organic vapor protection, so it handles vapor and dust in one cartridge.
Choose the 3M D8001 when the hazard is gas or vapor only, and the 3M D80921 when dust or mist is also present — spray painting, sanding or any task that mixes the two. Both fit only Secure Click respirators — not the bayonet 6000/7500 masks.

What the 3M D8001 and 3M D80921 Are Designed For
Both belong to 3M's Secure Click cartridge family — the push-and-click system used by the HF-800 half masks and FF-800 full facepieces, with an audible click confirming the cartridge is seated. They are part of 3M's wider 3M respirator filters and cartridges range. The 3M D8001 is built for organic vapor only; the 3M D80921 adds a P100 particulate filter to that same gas protection. The D8001 is the organic-vapor-only choice (like the bayonet 6001); the D80921 builds in P100 (like the 60921) for jobs that also create particulate.

Real-World Use Cases
Spray painting: the D80921 is the right pick because it adds P100 for paint mist alongside organic vapor. A bare D8001 filters the vapor but not the mist, so it is not appropriate for spraying on its own.
Solvent-only work: for wiping, degreasing and coatings with no dust, the D8001 is the lighter, lower-cost choice.
What These Cartridges Do Well
3M D8001 (Organic vapor):
- Organic vapor only on the Secure Click platform
- Quick, audible Secure Click attachment with low breathing resistance
- Lower cost than the combination and broader-range options
3M D80921 (Organic vapor + P100):
- Organic vapor with P100 particulate
- One cartridge for gas/vapor plus particulate — no separate filter to manage
- Same easy Secure Click fit as the 3M D8001
Where These Cartridges Are Not the Right Choice
The D8001 has no particulate filter, so it is not appropriate for spray painting or dusty work unless you add a Secure Click D3091 P100 or D3071 P95 filter — or simply use the D80921, which builds P100 in. Neither covers acid gas; for that use the D8003 or D80923. Neither fits bayonet respirators — they are Secure Click only, so on a 6000/6500/7500 mask you would use the bayonet equivalents instead (see our 6003 vs 6006 and 6001 vs 60921 comparisons).
3M D8001 vs D80921 vs Similar 3M Cartridges
| Cartridge | Protection | P100 particulate |
|---|---|---|
| D8001 | Organic vapor | No |
| D80921 | Organic vapor + P100 | Yes |
| 3M D8003 | Organic vapor + acid gas | No |
| 3M D80923 | OV + acid gas + P100 | Yes (P100) |
The Secure Click line mirrors the bayonet cartridges — D8001/D8003/D8006 match the 6001/6003/6006, and the D80921/D80923/D80926 add a P100 filter like the 60921/60923/60926. Rating background: N95 vs KN95 vs P100.
Compatible Respirators
The 3M D8001 and 3M D80921 use the 3M Secure Click connection and fit only the Secure Click respirators: the HF-800 series half masks and the FF-800 series full facepieces. They do not fit the bayonet 3M 6000, 6500/6500QL, 7500 or 7800S series, which use bayonet cartridges. Browse both systems in the 3M respirator filters and cartridges collection.
Who Should Buy This Cartridge?
Choose the D8001 if you are: handling solvent vapor only, with no dust or mist.
Choose the D80921 if you are: spray painting or doing any work that mixes organic vapor with particulate.
Final Recommendation
For solvent-vapor-only work the D8001 is the right, economical Secure Click choice; for spray painting or any task with particulate, the D80921 OV/P100 is the complete cartridge. For acid gases, step up to the 3M D8003 or 3M D80923. Match the cartridge to a documented hazard assessment, and use our how to choose a respirator cartridge guide alongside the 3M respirator filters and cartridges collection.

FAQ
What is the difference between the 3M D8001 and 3M D80921?
Both are 3M Secure Click cartridges with the same organic vapor gas protection. The 3M D80921 adds a P100 particulate filter, so it also captures dusts and mists, while the 3M D8001 is gas and vapor only. If your work creates particulate as well as vapor, the 3M D80921 is the complete cartridge.
Is the 3M D80921 better than the 3M D8001?
It is more complete, not simply better. The 3M D80921 does everything the 3M D8001 does plus P100 particulate. If you face vapor only, the 3M D8001 is lighter and lower cost; if particulate is also present, the 3M D80921 is the correct choice.
What is the 3M D8001 used for?
The 3M D8001 is a Secure Click cartridge providing organic vapor only. It has no particulate filter, so it covers gases and vapors only.
What is the 3M D80921 used for?
The 3M D80921 is a Secure Click cartridge providing organic vapor with P100 particulate. It suits work that combines those vapors or gases with dust or mist, such as spray painting and sanding.
Does the 3M D8001 filter dust or particulate?
No. The 3M D8001 is gas and vapor only. For dust or mist you add a Secure Click particulate filter such as the D3091 (P100) or D3071 (P95), or use the 3M D80921, which builds P100 in.
Does the 3M D80921 filter dust?
Yes. The 3M D80921 includes a P100 filter, capturing at least 99.97% of oil and non-oil particulate in addition to its gas and vapor protection.
What respirators do the 3M D8001 and 3M D80921 fit?
Both are 3M Secure Click cartridges and fit the Secure Click HF-800 series half masks and FF-800 series full facepieces. They use the Secure Click connection, not the bayonet connection.
Do the 3M D8001 and 3M D80921 fit 3M 6000 or 7500 respirators?
No. They are Secure Click cartridges and only fit Secure Click HF-800 and FF-800 respirators. They do not fit the bayonet 3M 6000, 6500/6500QL, 7500 or 7800S masks.
Is the 3M D80921 good for spray painting?
For spray painting, the 3M D80921 is the better pick because it adds P100 for the paint mist alongside organic vapor protection. A gas-only cartridge like the 3M D8001 would miss the particulate unless you add a separate filter.
Are the 3M D8001 and 3M D80921 NIOSH approved?
Yes. Both are NIOSH-approved 3M Secure Click cartridges. Confirm the approval number on the packaging matches your Secure Click facepiece and assembly.
How often should the 3M D8001 and 3M D80921 be replaced?
Gas and vapor cartridges have a limited service life and must be replaced on a documented change schedule before breakthrough. OSHA requires a change schedule for gas and vapor cartridges; follow your facility's respiratory protection program.
Do the 3M D8001 and 3M D80921 work with full face respirators?
Yes. Both fit the 3M Secure Click FF-800 series full facepieces as well as the HF-800 half masks. They do not fit bayonet full facepieces such as the 6000 or 7800S series.
Are the 3M D8001 and 3M D80921 P100?
The 3M D80921 includes a P100 filter; the 3M D8001 does not — it is a gas and vapor cartridge only. Add a Secure Click P100 filter to the 3M D8001 if you need particulate.
