Quick answer
Published · Last updated
Both are 3M valved P-series (oil-proof) disposable respirators — usable against oil and non-oil particulate. The 8271 is P95 (≥95%); the 8293 is P100 (≥99.97%) with a face seal for the highest disposable filtration. Choose the 8271 for general oil mists and particulate at lower cost, the 8293 for maximum protection in high or prolonged exposure (lead, fine particulate).
3M 8271 vs 3M 8293: at-a-glance
| Spec | 3M 8271 | 3M 8293 |
|---|---|---|
| NIOSH rating | P95 (≥95%, oil-proof) | P100 (≥99.97%, oil-proof) |
| Oil resistance | Oil-proof (P) | Oil-proof (P) |
| Exhalation valve | Yes — 3M Cool Flow | Yes — 3M Cool Flow |
| Face seal | Standard | Yes — added face seal |
| Filtration efficiency | ≥95% | ≥99.97% |
| Form factor | Molded cup | Molded cup |
| Best for | General oil mist + dust | High-hazard, max filtration |
The two respirators
3M 8271
The 3M 8271 is a P95 valved cup — oil-proof and rated for at least 95% of all particulates, oil or not. It’s the cost-effective pick for oil mists, paints, and general particulate where P100 isn’t required.
3M 8293
The 3M 8293 is a P100 valved cup with an added face seal, filtering at least 99.97% of all particulates including oil — the highest filtration available in a disposable, suited to high or prolonged exposure such as lead or fine particulate.
Key differences
Filtration level is the difference
Both are oil-proof P-series; the gap is efficiency — P95 (≥95%) on the 8271 versus P100 (≥99.97%) on the 8293. Step up when exposure is high, prolonged, or regulated.
The 8293’s face seal
The 8293 adds a face seal that improves the fit margin around the perimeter — helpful for the demanding tasks that justify P100.
Cost and comfort
P100 filtration and the face seal raise breathing resistance and cost; the 8271 is lighter and cheaper for everyday oil-mist work where ≥95% is sufficient.
Which should you buy?
| Your situation | Pick | Why |
|---|---|---|
| General oil mist, paint overspray, dust | 3M 8271 | P95 is sufficient and lower-cost |
| Lead, cadmium, fine or high particulate | 3M 8293 | P100 max filtration |
| Prolonged or regulated high exposure | 3M 8293 | ≥99.97% efficiency + face seal |
| Budget for routine particulate | 3M 8271 | Lower cost, lower breathing resistance |
| Need maximum disposable protection | 3M 8293 | Highest available FFR filtration |
| Non-oil only and cost-driven | Consider N-series | N95/N100 are cheaper where no oil is present |
Fit & compatibility
Both are valved P-series cups requiring a clean-shaven seal, an OSHA fit test, medical evaluation, and a user seal check. Not sure whether you even need a P-rating? See P95 vs R95 vs P100 and P100 vs N100 vs N95. Browse all valved respirators.

Key takeaways
- 3M 8271: General oil mist, paint overspray, dust — P95 is sufficient and lower-cost.
- 3M 8293: Lead, cadmium, fine or high particulate — P100 max filtration.
- 3M 8293: Prolonged or regulated high exposure — ≥99.97% efficiency + face seal.
Bottom line
Both the 3M 8271 and 3M 8293 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.

Why trust WC Safety
WC Safety is an independent, affiliate-supported review site. It is not a retailer: it holds no inventory, takes no orders, and earns only from qualifying purchases through clearly marked links — which never changes what a product is rated to do. Standards language is taken from the regulation text directly, and ratings are reported as the manufacturer publishes them. We run no laboratory and perform no testing of our own. Where published sources disagree, we say so and plan on the conservative figure rather than the flattering one.
Our methodology
Figures come from the regulation and the published specification, in that order. Derated numbers are calculated, not estimated. Nothing here is presented as a measured result, because we measure nothing.
