How can buyers verify the safety of a reusable PPE mask after multiple sterilization cycles?

Data is the only currency in 2026. Fanterco recommends requiring three specific data points:

1. ISO 18184 Post-Wash: Proof that antiviral efficacy remains >99% after 50 washes.
2. EN 14683 Comparison: A test report showing that Bacterial Filtration Efficiency (BFE) and pressure drop (breathability) are stable after sterilization.
3. NatureWorks Validation: EVerify that the non-woven utilizes a core-sheath bicomponent structure (PLA core for low-carbon stiffness, PP sheath for toughness). This specific molecular architecture is one of the very few non-woven technologies independently verified to withstand up to 50 cycles of vaporized hydrogen peroxide (VHP) or ozone sterilization without experiencing fiber degradation, loss of mechanical strength, or drop in sub-micron filtration efficiency.
