When selecting a surgical mask, it’s essential to look beyond appearance and comfort—certification matters. One of the most trusted indicators of mask performance is the ASTM rating, a standard developed by ASTM International (formerly the American Society for Testing and Materials). Among the three levels of ASTM certification, Level 3 represents the highest level of protection.
At USA MedPro, our surgical face masks are proudly made in the USA and tested to meet ASTM Level 3 certification, ensuring you get top-tier defense in the most demanding environments.
ASTM International sets global standards for a wide range of industries, including personal protective equipment (PPE). For surgical masks, ASTM standards evaluate three critical performance areas:
Each mask is assigned a level—1, 2, or 3—based on how it performs across these criteria.
| Feature | ASTM Level 1 | ASTM Level 2 | ASTM Level 3 |
| Fluid Resistance (mmHg) | 80 mmHg | 120 mmHg | 160 mmHg |
| BFE (Bacterial Filtration) | ≥95% | ≥98% | ≥98% |
| PFE (Particulate Filtration) | ≥95% | ≥98% | ≥98% |
| Delta P (Breathability) | < 4.0 mm H₂O/cm² | < 5.0 mm H₂O/cm² | < 5.0 mm H₂O/cm² |
| Flame Spread | Class 1 | Class 1 | Class 1 |
ASTM Level 3 masks protect against high-velocity fluid splashes, making them ideal for environments where blood, bodily fluids, or aerosolized particles are present—such as surgeries or emergency procedures.
They block at least 98% of bacteria and submicron particles, helping to protect both the wearer and surrounding individuals from potential infection.
Level 3 is recommended for:
Choosing a certified ASTM Level 3 mask ensures you’re using PPE that has been tested, validated, and proven to perform at the highest standard. In fast-paced, high-risk environments, there is no room for uncertainty. ASTM Level 3 offers peace of mind that you’re protected by science—not just marketing claims.
Whether you’re a healthcare worker, essential employee, or caring for others in a high-risk environment, our Level 3 masks provide the protection you need—when it matters most.
The Bottom Line:
ASTM Level 3 is the gold standard in surgical face mask protection. With USA MedPro, you’re not just wearing a mask—you’re wearing confidence.
