- BFE (Bacterial Filtration Efficiency) measures how effectively the mask filters bacteria-containing aerosols — higher is better.
- ΔP (Differential Pressure) indicates breathing resistance in mmH₂O/cm² — lower feels more breathable, balanced with filtration.
- Which to choose? Fresh Series emphasizes high filtration (BFE≧99%) with comfortable ΔP, suitable for clinics, admin roles, public service and commuting. For high-risk splash settings, follow your facility’s PPE protocol.
