Quick answer
Published · Last updated
Both are unvalved NIOSH N95s; the difference is form factor and brand. The 3M 8210 is a rigid molded cup; the Honeywell DF300 is a three-panel flat-fold that packs flat, is light on the face, and suits a range of face shapes. Choose the 8210 for bulk job-site dust and the DF300 for portability, comfort, and glasses.
3M 8210 vs Honeywell DF300: at-a-glance

|---|---|---|
| NIOSH rating | N95 (≥95% non-oil) | N95 (≥95% non-oil) |
| Exhalation valve | No | No |
| Form factor | Molded cup | 3-panel flat-fold |
| Brand | 3M | Honeywell |
| Storage | Bulky, holds shape | Folds flat |
| Fit range | One cup shape | Adapts to more faces |
| Typical pack | 20 / box | Bulk box |
| Best for | Bulk dust work | Portability, fit, eyewear |
The two respirators
3M 8210
The 3M 8210 is the rigid N95 cup standard — robust, economical in bulk, and easy to fit-test across a workforce.
Honeywell DF300
The Honeywell DF300 is a lightweight three-panel flat-fold N95. It folds flat for storage, sits low on the face, and its flexible panels adapt to more face shapes — a practical pick where portability and fit range matter.
Key differences
Cup vs flat-fold
The defining difference is shape: the 8210’s rigid cup holds form and is cheap in bulk; the DF300 folds flat, stores easily, and is lighter on the face.
Fit range
Flat-fold panels flex to the face, so the DF300 often fits contours a fixed cup can’t — helpful for raising fit-test pass rates across a mixed workforce.
Protection is identical
Both are NIOSH N95, unvalved, filtering the same. The choice is about form factor, storage, and fit — not efficiency.
Which should you buy?
| Your situation | Pick | Why |
|---|---|---|
| High-volume job-site dust | 3M 8210 | Lower unit cost in bulk |
| Portability / carry in a kit | Honeywell DF300 | Folds flat |
| Wider range of face shapes | Honeywell DF300 | Flexible flat-fold panels |
| Worn with glasses | Honeywell DF300 | Low profile, less bulk |
| Maximize fit-test pass rate | Fit-test both | Cup vs flat-fold geometry |
| Oil mist present | Neither — use R95/P-series | N-series are not rated for oil |
Fit & compatibility
Both are unvalved N95s requiring a clean-shaven seal, an OSHA fit test, medical evaluation, and a user seal check. Flat-folds like the DF300 often complement a cup program to cover more face shapes — see cup vs flat-fold. Browse all N95 respirators.

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.
