Key features:
1. Material & Layers
– 3-Layer Construction
– Outer Layer – Water-resistant (blocks droplets, splashes).
– Middle Layer – Melt-blown polypropylene (filters particles).
– Inner Layer – Soft, absorbent (for comfort against the skin).
– Material: Non-woven synthetic fabric (polypropylene, polyester).
2. Filtration Efficiency
– Face masks (medical-grade) have standardized filtration
– Non-medical disposables: ~60–80%
3. Fit & Seal
– Ear loops or head ties for secure placement.
– Adjustable nose wire (reduces gaps for better fit).
– Not airtight but minimizes exposure.
4. Protection Level
– Primary Use: Blocks droplets, splashes, and large particles.
– Source Control: Reduces the wearer’s respiratory emissions.
– Fluid Resistance
5. Comfort & Breathability
– Lightweight
6. Common Uses
– Healthcare settings (doctors, nurses, dental procedures).
– Public spaces (crowded areas, travel, sick individuals).
– Industrial/workplace safety (dust, pollution, construction).
7. Limitations
– Single-use only (discard after 4–8 hours)
