A 3 Ply Sterile Face Mask is a high-grade medical protective covering designed for environments requiring the highest level of infection control, such as operating rooms, ICUs, and burn units. Unlike standard masks, these undergo rigorous sterilization (often via gamma radiation or ethylene oxide) and are typically individually packaged to maintain a germ-free state until the moment of use.
Key Specifications & Layered ConstructionEach mask consists of three distinct layers of non-woven polypropylene fabric, usually bonded via ultrasonic welding
- Outer Layer (Hydrophobic): Water-repellent spun-bond fabric that blocks large droplets, splashes, and sprays (e.g., blood or saliva).
- Middle Layer (Melt-blown Filter): The "powerhouse" layer made of electrostatically charged melt-blown polypropylene. It captures microscopic particles, including bacteria and viruses, typically providing a Bacterial Filtration Efficiency (BFE) of ≥98%.
- Inner Layer (Hydrophilic): Soft, skin-friendly, and absorbent fabric that wicks away moisture from breathing and perspiration to enhance comfort and reduce eyewear fogging
