Quick answer
Both are 3M non-oil (N-series) disposable respirators; the difference is filtration level. The 8210 is N95 (≥95% non-oil); the 8233 is N100 (≥99.97% non-oil) with a Cool Flow valve and face seal for the highest non-oil disposable protection. Choose the 8210 for general dust, the 8233 for high-hazard particulate such as lead, asbestos support, or heavy fume.
3M 8210 vs 3M 8233: at-a-glance
| Spec | 3M 8210 | 3M 8233 |
|---|---|---|
| NIOSH rating | N95 (≥95% non-oil) | N100 (≥99.97% non-oil) |
| Filtration efficiency | ≥95% | ≥99.97% |
| Exhalation valve | No | Yes — 3M Cool Flow |
| Face seal | Standard | Yes — added face seal |
| Oil resistance | None (N-series) | None (N-series) |
| Form factor | Molded cup | Molded cup |
| Best for | General dust | High-hazard non-oil particulate |
The two respirators
3M 8210
The 3M 8210 is the standard N95 cup for general dust and particulate — economical, widely available, and unvalved.
3M 8233
The 3M 8233 is an N100 cup with a Cool Flow valve and face seal, filtering at least 99.97% of non-oil particles — the top non-oil disposable, reserved for high or regulated exposures.
Key differences
How much filtration you need
Both are non-oil N-series; the difference is efficiency — N95 (≥95%) versus N100 (≥99.97%). Most dust work is fine with N95; step to N100 for high-hazard particulate.
Valve and face seal
The 8233 adds a Cool Flow valve and face seal for comfort and a tighter perimeter on demanding jobs; the 8210 is the simpler, cheaper everyday option.
When N100 is warranted
Reach for the 8233 with regulated metals (lead, cadmium), asbestos-abatement support, and heavy welding fume — situations where the extra filtration margin matters.
Which should you buy?
| Your situation | Pick | Why |
|---|---|---|
| General construction or woodworking dust | 3M 8210 | N95 is sufficient and lower-cost |
| Lead, cadmium, regulated metal dust | 3M 8233 | N100 max non-oil filtration |
| Asbestos-abatement support, heavy fume | 3M 8233 | Higher filtration margin |
| Budget, high-volume dust | 3M 8210 | Lower cost, unvalved |
| Comfort on hot, demanding jobs | 3M 8233 | Valve vents heat |
| Oil mist present | Neither — use P-series | N-series are not rated for oil |
Fit & compatibility
Both are molded-cup respirators requiring a clean-shaven seal, an OSHA fit test, medical evaluation, and a user seal check. Deciding how much filtration you need? See P100 vs N100 vs N95. For the valve question on the N95, compare 8210 vs 8511. Browse all N95 respirators.

Key takeaways
- 3M 8210: General construction or woodworking dust — N95 is sufficient and lower-cost.
- 3M 8233: Lead, cadmium, regulated metal dust — N100 max non-oil filtration.
- 3M 8233: Asbestos-abatement support, heavy fume — Higher filtration margin.
Bottom line
Both the 3M 8210 and 3M 8233 meet their NIOSH rating, so the choice is about matching the respirator to the task, the wearer’s fit, and your budget — not whether you are protected. Work through the at-a-glance table and the scenarios above, then fit-test your pick before relying on it in a hazardous atmosphere.

Frequently asked questions: 3M 8210 vs 3M 8233
What is the difference between the 3M 8210 and 8233?
Both are non-oil (N-series) cups. The 8210 is N95 (≥95%); the 8233 is N100 (≥99.97%) with a Cool Flow valve and face seal for the highest non-oil filtration.
When do I need an N100 instead of an N95?
Step up to N100 (the 8233) for high or prolonged exposure to regulated particulate — lead, cadmium, asbestos-abatement support, or heavy welding fume.
Are both the 8210 and 8233 non-oil only?
Yes. Both are N-series, rated only for non-oil particulate. For oil aerosols, use a P-series respirator.
Does the 8233 have a valve?
Yes, the 8233 has a Cool Flow exhalation valve and an added face seal; the 8210 is unvalved.
Is the 8233 worth it over the 8210?
Only when your exposure justifies N100. For general dust, the 8210 is more economical; for high-hazard particulate, the 8233’s filtration is worth it.
Are both NIOSH approved?
Yes. The 8210 is NIOSH N95 and the 8233 is NIOSH N100; both filter non-oil particulate to their rated efficiency.
Do the 8210 and 8233 require fit testing?
Yes. Both are tight-fitting respirators requiring fit testing, medical evaluation, and a user seal check for regulated work.
Are the 8210 and 8233 reusable?
No. Both are single-use; discard when damaged, soiled, wet, or harder to breathe through.
Can I use the 8233 for lead?
N100 is generally appropriate for lead and similar regulated metals; confirm against your exposure assessment and the applicable OSHA standard.
Which is easier to breathe through?
The N95 8210 has lower breathing resistance; the N100 8233 filters more but breathes harder, eased somewhat by its valve.
