An ASTM F2100 Level 2 mask is a barrier mask, measured against a laboratory standard rather than against smoke. The standard grades BFE, PFE, differential pressure, fluid resistance and flame spread — none of which involves surgical smoke. Smoke control comes from local exhaust at the source and, where a hazard assessment calls for it, a respirator program.
Quick facts
- ASTM F2100 covers five mask tests: BFE, PFE, differential pressure, fluid resistance and flame spread.
- The standard publishes three barrier levels, and a mask carries the level it met.
- BFE and PFE are laboratory material tests, not fit tests and not clinical results.
- Differential pressure describes breathability; fluid resistance describes behaviour against a splash.
- No ASTM F2100 level covers smoke or vapour.
What is ASTM F2100?
ASTM F2100 tells a manufacturer how to measure and report a medical face mask's barrier performance. Its value to a buyer is comparison: two products judged on the same tests.
Five measurements sit inside it. BFE and PFE challenge the material with particles and report how much it holds back; differential pressure records how hard air moves through it, which is shorthand for breathability. Fluid resistance covers behaviour against a liquid splash at a set pressure, and flame spread covers a flame test.
What it leaves out matters too: fit, the air around a handpiece, and respiratory protection. The product safety hub keeps the reading behind those gaps.
What do BFE and PFE measure?
BFE and PFE are the two figures quoted most often, and they are not the same test. BFE uses a bacterial particle challenge; PFE uses a sub-micron particle challenge.
Scope is the part worth pinning down. Both are material tests under defined conditions — not a measure of what reaches a person during a procedure, and not a fit test. High PFE with a gap at the cheeks is still a gap, which is why level choice travels with sizing.
Will an ASTM F2100 Level 2 mask reduce smoke particles?
No — not in the sense the question usually means. A Level 2 mask meets a stated barrier expectation for particles and fluid splash under laboratory conditions. Surgical smoke is fine particulate and vapour, and ASTM F2100 tests none of it.
That is not a knock on the mask; it is a statement about what the standard is for. What does work is an engineering control: local exhaust at the point of generation.
What smoke control actually requires
Where a hazard assessment says a respirator is needed, that is a separate program — fit testing, medical evaluation, selection and record-keeping under provincial occupational health rules and CSA guidance. A surgical mask is not a respirator, and no ASTM F2100 level changes that.
| Level | What the label means | Smoke control? |
|---|---|---|
| Level 1 | lowest of the three barrier expectations | No |
| Level 2 | mid-tier expectations | No |
| Level 3 | highest of the three | No |
| Not an ASTM level | respirator certification, a separate program | Only via that program |
Which ASTM level does a clinic need?
Start from the task, not the level number. Short routine exams usually sit with a Level 1 procedural mask; procedures with more spray and splash point most clinics to Level 2 or Level 3.
CliniEco Medical Face Mask — 3-Ply ASTM Level 3, 50-Pack is labelled to the ASTM Level 3 expectations, and CliniEco Disposable Face Masks — 3-Ply, Comfort Fit, 50 Pack covers the lighter routine side.
For teams adding daily checks on the sterilization side, CliniEco 24h Biological Indicator — 5-Pack Trial is a small starting quantity with shipping included.

Frequently Asked Questions
Will an ASTM F2100 Level 2 mask reduce surgical smoke?
No. ASTM F2100 measures barrier performance — BFE, PFE, differential pressure, fluid resistance and flame spread. Surgical smoke needs local exhaust or smoke evacuation, plus a respirator program where a hazard assessment requires one.
What do BFE and PFE actually measure?
Both are laboratory material tests. BFE uses a bacterial particle challenge and PFE uses a sub-micron particle challenge.
Is ASTM F2100 a respirator certification?
No. It is a medical face mask barrier standard; respirators sit in a separate program with fit testing and a hazard assessment.
Which ASTM level does my clinic need?
Match it to the task. Light routine use suits Level 1, while longer procedures with more spray and splash lead most clinics to Level 2 or Level 3.
