Medical Mask Protection Standards: ASTM F2100, EN 14683, EN 149
Medical Mask Protection Standards: ASTM F2100, EN 14683, EN 149
Highlights：
Masks are a critical tool for protection, and their quality and performance directly impact user safety. In the global market, the main standards include ASTM F2100 (U.S.), EN 14683 (EU medical), and EN 149 (EU respirator). Each addresses different usage scenarios and protection needs. For importers and exporters, knowing these standards supports compliance and market growth; for everyday consumers, it helps ensure they choose masks that truly meet their safety needs.
ASTM F2100 – U.S. Medical Mask Standard
ASTM F2100 is the U.S. performance standard for medical masks. It classifies masks into Level 1, Level 2, and Level 3 based on different protection needs and test thresholds.
- BFE (Bacterial Filtration Efficiency): ≥95% (Level 1), ≥98% (Levels 2 & 3)
- PFE (Particle Filtration Efficiency): Same thresholds as BFE
- Fluid Resistance: 80 mmHg (Level 1), 120 mmHg (Level 2), 160 mmHg (Level 3)
- Differential Pressure (ΔP): Lower values indicate easier breathability
| Level | BFE (3 μm) | PFE (0.1 μm) | Fluid Resistance (mmHg) | ΔP (mm H₂O/cm²) | Typical Use |
|---|---|---|---|---|---|
| Level 1 | ≥95% | ≥95% | 80 | ≤5.0 | Basic medical protection |
| Level 2 | ≥98% | ≥98% | 120 | ≤6.0 | Moderate-risk medical procedures |
| Level 3 | ≥98% | ≥98% | 160 | ≤6.0 | High-risk environments with fluid exposure |
EN 14683 – EU Medical Mask Standard
EN 14683 classifies medical masks into three categories: Type I, Type II, and Type IIR.
- Type I: BFE ≥95%; mainly for low-risk medical settings
- Type II: BFE ≥98%; no fluid resistance
- Type IIR: BFE ≥98%; with fluid resistance (120 mmHg)
| Type | BFE (3 μm) | Fluid Resistance (mmHg) | ΔP (Pa/cm²) – Adult | Typical Use |
|---|---|---|---|---|
| Type I | ≥95% | None | <40 | General low-risk medical use |
| Type II | ≥98% | None | <40 | Standard medical procedures |
| Type IIR | ≥98% | 120 | <60 | High-risk environments with fluid exposure |
EN 149 – EU Respiratory Protection Standard
EN 149 applies to FFP (Filtering Facepiece) respirators, commonly used in industrial dust settings and high-protection medical environments.
- FFP1: Filtration efficiency ≥80%; Total Inward Leakage (TIL) <22%
- FFP2: Filtration efficiency ≥94%; TIL <8%
- FFP3: Filtration efficiency ≥99%; TIL <2%
| Class | Particle Filtration (0.6 μm NaCl) | Total Inward Leakage (TIL) | Typical Use |
|---|---|---|---|
| FFP1 | ≥80% | <22% | Protection against non-toxic dusts |
| FFP2 | ≥94% | <8% | Protection against harmful industrial dusts; suitable for higher-risk medical use |
| FFP3 | ≥99% | <2% | Protection against toxic dusts and aerosols; highest level of protection |
The Science Behind Mask Standards: Filtration Efficiency、Fluid Resistance、Breathability and Comfort
Filtration Efficiency: BFE and PFE
BFE measures a mask’s ability to block bacteria-sized particles of about 3 μm in diameter, while PFE evaluates its effectiveness against much smaller particles around 0.1 μm. ASTM and EN 14683 use different testing methods, so results should be compared with caution.
Fluid Resistance
Although ASTM and EN 14683 apply different methods, both simulate splatter scenarios using synthetic blood. ASTM Level 3 and EN 14683 Type IIR are recommended for high-risk environments with fluid exposure.
Breathability and Comfort
Both ASTM and EN standards set limits on differential pressure (ΔP) to ensure breathability. EN 149 goes a step further by measuring Total Inward Leakage (TIL), ensuring a proper seal for maximum protection.
Comparison of the Three Major Mask Standards
| Category | ASTM F2100 (U.S. Medical) | EN 14683 (EU Medical) | EN 149 (EU Respirator) |
|---|---|---|---|
| Classification | Level 1 / Level 2 / Level 3 | Type I / Type II / Type IIR | FFP1 / FFP2 / FFP3 |
| BFE (Bacterial Filtration Efficiency) | Level 1: ≥95% Level 2/3: ≥98% | Type I: ≥95% Type II/IIR: ≥98% | Not applicable (focus on total filtration efficiency) |
| PFE (Particle Filtration Efficiency) | ≥95–98% (0.1 μm particles) | Not specified | FFP1: ≥80% FFP2: ≥94% FFP3: ≥99% (tested with 0.6 μm NaCl) |
| Fluid Resistance | Level 1: 80 mmHg Level 2: 120 mmHg Level 3: 160 mmHg | Type I / II: None Type IIR: 120 mmHg | None (non-medical design) |
| Breathability (ΔP) | Level 1: ΔP <5.0 mm H₂O/cm² Level 2/3: ΔP <6.0 mm H₂O/cm² | Type I/II: <40 Pa/cm² Type IIR: <60 Pa/cm² | Regulates inhalation and exhalation resistance; higher grades mean higher resistance |
| Total Inward Leakage (TIL) | Not specified | Not specified | FFP1: <22% FFP2: <8% FFP3: <2% |

From Everyday Use to Professional Settings: Mask Selection Tips
Guidelines for Importers and Exporters
- For the U.S. market: ASTM F2100
- For the EU market: EN 14683 or EN 149
- For global trade: dual certification is the safest choice
Tips for Everyday Consumers
- Daily protection: ASTM Level 1 or EN 14683 Type I
- High-risk environments: ASTM Level 2/3 or EN 14683 Type IIR
