3M D8003 vs D8006: Secure Click Acid Gas vs Multi-Gas (2026)
Quick Verdict
Reviewed by the WC Safety Editorial Team — Last updated: June 2026.
The 3M D8003 (vendor: 3M, SKU D8003) and the 3M D8006 (vendor: 3M, SKU D8006) are both 3M Secure Click cartridges for the HF-800 and FF-800 respirators. The 3M D8003 provides organic vapor and acid gas; the 3M D8006 provides multi-gas (organic vapor, acid gas, ammonia, methylamine and formaldehyde). The D8006 covers everything the D8003 does plus ammonia, methylamine and formaldehyde, so it is the broader multi-gas option.
Choose the 3M D8003 when your exposure stays within its range, and the 3M D8006 when ammonia or formaldehyde may also be present. Both fit only Secure Click respirators — not the bayonet 6000/7500 masks.

What the 3M D8003 and 3M D8006 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 D8003 is built for organic vapor and acid gas; the 3M D8006 extends the gas range to organic vapor, acid gases, ammonia, methylamine and formaldehyde. The D8003 is the organic-vapor-and-acid-gas choice; the D8006 is the multi-gas cartridge for mixed or unpredictable chemistry.

Real-World Use Cases
Water & chemical handling: for solvent vapor with chlorine or sulfur dioxide, the D8003 is sufficient. Where ammonia (refrigeration, fertiliser) or formaldehyde (labs, resins) is also present, the D8006 is required.
Manufacturing & maintenance: the D8006 suits broad, variable chemical environments; the D8003 suits known organic-vapor-and-acid-gas tasks. Neither covers particulate — add a Secure Click D3091 P100 or D3071 P95 filter, or use the combination D80923/D80926.
What These Cartridges Do Well
3M D8003 (Organic vapor + acid gas):
- Organic vapor and acid gas on the Secure Click platform
- Quick, audible Secure Click attachment with low breathing resistance
- Lower cost than the combination and broader-range options
3M D8006 (Multi-gas / vapor):
- Multi-gas (organic vapor, acid gas, ammonia, methylamine and formaldehyde)
- One cartridge for the broader chemical range
- Same easy Secure Click fit as the 3M D8003
Where These Cartridges Are Not the Right Choice
The D8003 does not cover ammonia, methylamine or formaldehyde — for those use the D8006. Neither has a particulate filter, so for dust or mist add a Secure Click D3091 P100 or D3071 P95 filter, or use the P100 combination D80923 or D80926. 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 D8003 vs D8006 vs Similar 3M Cartridges
| Cartridge | Protection | P100 particulate |
|---|---|---|
| D8003 | Organic vapor + acid gas | No |
| D8006 | Multi-gas / vapor | No |
| 3M D8001 | Organic vapor | 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 D8003 and 3M D8006 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 D8003 if you are: working with solvent vapor and acid gases such as chlorine or sulfur dioxide on a Secure Click respirator.
Choose the D8006 if you are: facing ammonia, methylamine, formaldehyde or mixed and unpredictable chemistry.
Final Recommendation
For known organic-vapor-and-acid-gas work the D8003 is the right, economical Secure Click choice; step up to the D8006 when ammonia, formaldehyde or mixed chemistry is in play. When particulate is also present, use the P100 combination 3M D80923 or 3M D80926. 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 D8003 and 3M D8006?
Both are 3M Secure Click cartridges. The 3M D8003 covers organic vapor and acid gas; the 3M D8006 extends that to organic vapor, acid gases, ammonia, methylamine and formaldehyde. If your exposure is within the 3M D8003's range, it is enough; if ammonia or formaldehyde is present, you need the 3M D8006.
Is the 3M D8006 better than the 3M D8003?
It is broader, not automatically better. The 3M D8006 covers everything the 3M D8003 does plus ammonia or formaldehyde. If you do not face ammonia or formaldehyde, the 3M D8003 is the right, lower-cost option.
What is the 3M D8003 used for?
The 3M D8003 is a Secure Click cartridge providing organic vapor and acid gas. It has no particulate filter, so it covers gases and vapors only.
What is the 3M D8006 used for?
The 3M D8006 is a Secure Click cartridge providing multi-gas (organic vapor, acid gas, ammonia, methylamine and formaldehyde). It suits broader chemical exposures where ammonia or formaldehyde may be present.
Does the 3M D8003 protect against ammonia or formaldehyde?
No. The 3M D8003 covers organic vapor and acid gas and is not approved for ammonia or formaldehyde. For that you need the 3M D8006.
Does the 3M D8006 protect against ammonia or formaldehyde?
Yes. The 3M D8006 is NIOSH-approved across organic vapor, acid gases, ammonia, methylamine and formaldehyde.
What respirators do the 3M D8003 and 3M D8006 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 D8003 and 3M D8006 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 D8006 good for spray painting?
Both cover the organic vapor in paint. Spray painting also creates mist (particulate), which neither covers alone — for spraying add a particulate filter or use the P100 combination version.
Are the 3M D8003 and 3M D8006 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 D8003 and 3M D8006 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 D8003 and 3M D8006 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 D8003 and 3M D8006 P100?
Neither is P100 on its own — both are gas and vapor cartridges with no particulate filter. For P100 add a Secure Click filter or use a combination cartridge such as the D80923 or D80926.
