EN 14683 vs ASTM F2100: Face Mask Standards Compared for Canadian Buyers
Quick Summary: Two standards dominate medical face mask performance specs — ASTM F2100 in North America and EN 14683 in Europe. Canadian buyers see both on supplier data sheets, especially when importing from overseas. This guide breaks down what each standard tests (BFE, PFE, differential pressure, splash resistance), maps the levels against each other (ASTM Level 1/2/3 vs EN Type I/II/IIR), and explains what to look for when a supplier quotes one standard or the other. Read time: 6 minutes.
1. Why Two Standards Confuse Canadian Buyers
Walk into any Canadian clinic supply room and you will find boxes of masks labeled ASTM Level 1, ASTM Level 2, and occasionally "EN 14683 Type IIR." The ASTM label is familiar to North American buyers. The EN label appears on imports from Europe and parts of Asia. Most procurement teams know the ASTM levels roughly, but the EN classification is a black box for many — which is a problem, because a mask labeled "Type IIR" is not automatically equivalent to a specific ASTM level.
The two standards were written by different organizations for different markets. ASTM F2100 is published by ASTM International and is the de facto reference for North American surgical masks. EN 14683 is a European standard harmonized under the EU Medical Devices Regulation, covering medical face masks in Europe. Both measure the same core performance properties — bacterial filtration, particle filtration, breathability, and splash resistance — but they set different thresholds, test methods, and level structures.
For a Canadian buyer, the practical question is never "which standard is better." It is "does this product meet the performance level my clinical setting requires, regardless of which label is on the box?" This guide gives you the mapping to answer that question.
2. The Four Performance Properties Both Standards Measure
Both ASTM F2100 and EN 14683 evaluate four properties, though with slightly different test methods:
| Property | What it measures | Why it matters |
|---|---|---|
| BFE (Bacterial Filtration Efficiency) | Percentage of bacteria-sized particles (3.0 µm) blocked by the filter layer | Core indicator of barrier performance against respiratory droplets |
| PFE (Particle Filtration Efficiency) | Percentage of submicron particles (0.1 µm) blocked | Better proxy for viral particle protection |
| Differential pressure (ΔP) | Breathability — pressure drop across the mask material | High filtration with poor breathability reduces wear time and compliance |
| Splash resistance | Resistance to synthetic blood penetration (ASTM) or splash (EN) | Protection against blood/body fluid exposure in procedural settings |
A common misunderstanding is that BFE and PFE are interchangeable. They are not. BFE uses a larger particle size (about 3.0 µm) and is generally higher than PFE on the same material. PFE tests 0.1 µm particles and is the stricter measure for viral filtration claims. When a supplier lists only BFE, ask for PFE too — a mask can have 99% BFE but only 80% PFE, which changes the risk profile for aerosol-generating procedures.
3. ASTM F2100 Levels: The North American Reference
ASTM F2100 defines three levels of performance for medical face masks:
| Property | Level 1 (Low barrier) | Level 2 (Moderate barrier) | Level 3 (High barrier) |
|---|---|---|---|
| BFE | ≥ 95% | ≥ 98% | ≥ 98% |
| PFE (0.1 µm) | ≥ 95% | ≥ 98% | ≥ 98% |
| Differential pressure | < 4.0 mm H₂O/cm² | < 5.0 mm H₂O/cm² | < 5.0 mm H₂O/cm² |
| Splash resistance (synthetic blood) | ≥ 80 mm Hg | ≥ 120 mm Hg | ≥ 160 mm Hg |
| Flame spread | Class 1 | Class 1 | Class 1 |
The level system gives procurement teams a quick shorthand: Level 1 for low-risk, non-splash procedures; Level 2 for moderate barrier needs; Level 3 for high-fluid-risk environments such as surgery and emergency departments. Most Canadian dental and primary care clinics default to Level 2 or Level 3 masks depending on the aerosol risk of the procedure.
Note that ASTM F2100 does not mandate a specific particle filtration efficiency test method for all levels identically — the key differentiators between Level 2 and Level 3 are splash resistance (120 vs 160 mm Hg) and the slightly tighter breathability ceiling. That means a Level 2 mask can have the same BFE/PFE as a Level 3 mask; the difference is fluid resistance.
4. EN 14683 Types: The European System
EN 14683 defines three types for medical face masks:
| Property | Type I | Type II | Type IIR |
|---|---|---|---|
| BFE | ≥ 95% | ≥ 98% | ≥ 98% |
| Differential pressure | < 40 Pa/cm² | < 40 Pa/cm² | < 60 Pa/cm² |
| Splash resistance | Not required | Not required | ≥ 120 mm Hg (splash test) |
| Microbial cleanliness (bioburden) | ≤ 30 cfu/g | ≤ 30 cfu/g | ≤ 30 cfu/g |
Three details stand out. First, EN 14683 does not require PFE — only BFE. This is a significant gap for buyers who care about submicron filtration; you cannot infer PFE from an EN label. Second, Type I masks are intended for patients and the general public, not healthcare workers. If a supplier quotes "EN Type I" for staff use, that is a red flag in a clinical setting. Third, the "R" in Type IIR stands for splash-resistant — it is the only EN type with a fluid-resistance requirement, and it is the type appropriate for surgical/procedural use.
5. Mapping the Two Standards: A Practical Comparison
There is no official one-to-one equivalence table published by ASTM or CEN, but for practical procurement purposes the closest mapping is:
| Performance need | ASTM F2100 | EN 14683 | Equivalent enough? |
|---|---|---|---|
| Patient use / low risk | Level 1 | Type I (patient use) | Approximate — both ~95% BFE |
| General clinical use | Level 1 | Type II | Approximate — Type II has higher BFE (98%) but no PFE requirement |
| Procedural / moderate | Level 2 | Type IIR | Closest clinical match — both have splash resistance |
| High barrier / surgical | Level 3 | Type IIR (with higher fluid claims) | Not directly equivalent — Level 3 requires ≥160 mm Hg splash; IIR requires ≥120 mm Hg |
The most dangerous assumption a buyer can make is treating "Type IIR" as automatically equal to "ASTM Level 3." A Type IIR mask meets a 120 mm Hg splash threshold; an ASTM Level 3 mask must meet 160 mm Hg. For Canadian surgical environments that specify Level 3, accepting a Type IIR substitute without reviewing the actual test report is a compliance gap.
6. Why PFE Matters and EN 14683 Doesn't Test It
PFE is the single most requested specification in Canadian hospital procurement RFPs — and it is entirely absent from EN 14683. This asymmetry creates a real risk for importers: a European factory can supply an EN 14683 Type IIR mask with excellent BFE (98%+) but no published PFE, and a buyer who does not ask will never know whether the filter catches 0.1 µm particles at 90%, 95%, or 98%.
For droplet-based transmission, BFE is a reasonable proxy. For aerosol-generating procedures, where smaller particles stay airborne longer, PFE is the more informative number. Canadian guidance on mask selection for aerosol-generating medical procedures generally points toward higher filtration efficiency — which means asking for both BFE and PFE data regardless of which standard is printed on the box.
If a supplier cannot provide PFE data, ask why. Some will say "EN 14683 doesn't require it," which is true but does not answer the clinical question. Reputable manufacturers test to the stricter requirement (typically ASTM F2100 for North American supply) or publish both datasets.
7. What Canadian Regulations and Guidance Say
Canada does not mandate a single mask standard for all clinical settings. The regulatory and guidance picture is layered:
- Health Canada regulates medical masks as Class I medical devices. Manufacturers and importers must hold a Medical Device Establishment Licence (MDEL) and masks must meet recognized standards such as ASTM F2100 or equivalent. Health Canada has issued guidance on mask standards during respiratory virus seasons, pointing to ASTM F2100 levels and, for respirators, NIOSH certification.
- Provincial public health guidance — for example, Ontario's Ministry of Health recommendations for healthcare settings — typically references ASTM F2100 Level 1-3 and NIOSH N95 for respiratory protection, rather than EN 14683. This makes ASTM the default compliance language for Canadian procurement.
- CSA standards for healthcare facilities reference recognized mask standards in the context of infection prevention and control programs.
In practice, this means a Canadian buyer can legally purchase an EN 14683 Type IIR mask, but provincial guidance and hospital procurement specifications will most often ask for ASTM levels. If you standardize on EN 14683 products, expect to do extra documentation work to demonstrate equivalence — and expect some Canadian customers to decline the substitution outright.
8. Procurement Checklist: Buying Masks With Confidence
Use this checklist the next time you evaluate a mask supplier, whether they quote ASTM, EN, or both:
- Ask for the full test report, not the label. Confirm BFE, PFE (if available), differential pressure, and splash resistance with actual numbers.
- Know your setting's requirement — dental aerosol procedures typically need Level 2/3; low-risk exams can use Level 1. Match the mask to the procedure, not to the cheapest box.
- If the supplier quotes EN 14683 only, ask for the PFE value and the splash test result before accepting it for procedural use.
- Check the medical device status — the importer should hold a valid MDEL and the product should be listed appropriately with Health Canada.
- Verify lot traceability — masks are sterile-adjacent products; confirm lot numbers and expiry dates on receipt.
- Test breathability in practice — a mask that staff find uncomfortable will be worn incorrectly. Run a small in-clinic trial before committing to a large order.
Facilities that standardize on a verified ASTM Level 3 mask for high-risk procedures and keep a Level 2 option for routine work tend to get the right balance of protection, compliance, and cost. Adding a bulk case SKU for high-volume clinics keeps per-unit pricing predictable — see our CliniEco 3-Ply ASTM mask bulk 10-box case for facilities that move through masks quickly.

10. FAQ
Q1: Is EN 14683 Type IIR the same as ASTM Level 3?
Not exactly. Both have BFE ≥98% and splash resistance, but ASTM Level 3 requires a higher splash threshold (160 mm Hg vs 120 mm Hg for IIR). Type IIR also has no PFE requirement. Review the actual test report before treating them as interchangeable.
Q2: Why does EN 14683 not test PFE?
The European standard's scope focuses on bacterial filtration, breathability, and (for Type IIR) splash resistance. PFE is a North American convention for medical masks. That is why EN-only data sheets often lack PFE — always ask for it separately.
Q3: Which ASTM level do Canadian dental clinics need?
Most Canadian dental practices use Level 2 or Level 3 masks, with Level 3 preferred for aerosol-generating procedures. Check your provincial dental regulator's guidance for the specific requirement.
Q4: Can patients wear healthcare worker masks?
Patients and visitors can wear any medical mask, but EN 14683 Type I is explicitly designed for patient/public use. For healthcare workers performing procedures, use Type IIR (or ASTM Level 2/3) — not Type I.
Q5: Does Health Canada require ASTM F2100?
Health Canada regulates masks as Class I medical devices and requires them to meet recognized standards. ASTM F2100 is the commonly cited standard in Canada; EN 14683 may also be acceptable with documentation, but provincial procurement often specifies ASTM.
Q6: What does differential pressure tell me?
It measures breathability. Lower ΔP means easier breathing and better wear compliance. A mask with excellent filtration but very high ΔP will be worn incorrectly or removed early — check ΔP alongside BFE/PFE.
Q7: Should I buy masks with both ASTM and EN labels?
Dual-labeled masks are common from manufacturers who test to both markets. That is a convenience, not a guarantee — still request the underlying test report to confirm actual values.
Q8: Are surgical masks the same as respirators?
No. Surgical masks (ASTM F2100 or EN 14683) are loose-fitting barrier products. Respirators (e.g., NIOSH N95) are tight-fitting and filter airborne particles. They serve different purposes and are not interchangeable.
11. Final Word for Canadian Buyers
Mask standards are a language, and Canadian procurement speaks ASTM. The EN 14683 vs ASTM F2100 comparison matters most when suppliers quote European standards — the mapping is close but not exact, and the differences (PFE, splash thresholds) can matter clinically. The disciplined approach is simple: specify the performance level your procedures require, request the test report, and verify the numbers rather than trusting the label.
