Quick answer
Published · Last updated
Both are unvalved NIOSH N95 respirators — the difference is the shape. The 8210 is a rigid molded cup that ships in bulk boxes; the 9210+ Aura is a three-panel flat-fold that’s individually wrapped, packs flat, sits low on the face, and has an embossed top panel that helps reduce eyewear fogging. Choose the 8210 for bulk job-site dust; the 9210+ for portability, comfort with glasses, and frequent on/off use.

| Form factor | Molded cup | 3-panel flat-fold |
| Packaging | Bulk box | Individually wrapped |
| Storage | Bulky, holds shape | Folds flat, pocketable |
| Eyewear fogging | Standard | Reduced (embossed top panel) |

The two respirators
3M 8210
The 3M 8210 is the classic rigid N95 cup — durable, holds its dome shape, and economical in bulk boxes. It’s the workhorse for steady job-site dust where masks are donned once and worn through a task.
3M 9210+ Aura
The 3M 9210+ Aura is a three-panel flat-fold N95. Each mask is individually wrapped and folds flat for a pocket or glovebox, the chin tab makes donning easy, and the embossed top panel directs exhaled air away from the eyes to cut fogging — a favorite for anyone who wears glasses or moves and talks a lot.
Key differences
Shape and storage
The biggest difference is form factor. The 8210’s rigid cup is robust but bulky; the 9210+ folds flat and is individually wrapped, so it’s easy to carry, store, and keep clean until use.
Eyewear and fogging
The Aura’s embossed top panel and nose foam channel exhaled air away from the eyes, noticeably reducing fogging for glasses and safety-eyewear wearers. The cup offers no such feature.
Comfort, talking and fit range
The flexible three-panel design flexes as you talk and move and tends to fit a wider range of face shapes; the rigid cup is simpler but less forgiving. Filtration is identical N95 on both.
Cost
The molded cup is usually cheaper per mask in bulk, so for high-volume dust work the 8210 wins on price; the 9210+ commands a small premium for its packaging and comfort.
Which should you buy?
| Your situation | Pick | Why |
|---|---|---|
| High-volume job-site dust | 3M 8210 | Lower unit cost in bulk |
| Carry in a pocket, truck, or kit | 3M 9210+ Aura | Folds flat, individually wrapped |
| Worn with glasses or safety eyewear | 3M 9210+ Aura | Top panel reduces fogging |
| Lots of talking / face movement | 3M 9210+ Aura | Flexible panels move with the face |
| Hygiene / one mask at a time | 3M 9210+ Aura | Individually sealed |
| Need a valve version | 3M 9211+ | 9211+ is the valved Aura |
Fit & compatibility
Both are one-size, unvalved N95s requiring a clean-shaven seal, an OSHA fit test, medical evaluation, and a user seal check. The Aura’s flat-fold panels often suit faces that struggle with a rigid cup — see our facial-hair guide for seal requirements. Want the cup with a valve instead? Compare the 8210 vs 8511.

Bottom line
Both the 3M 8210 and 3M 9210+ Aura 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.

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.
