Level 3 face masks offer maximum barrier protection against fluids, sprays, and aerosols. They are typically used in high-risk environments where exposure to these substances is likely. Level 3 masks are often called "surgical masks" or "medical masks" and are designed to provide a tight seal around the nose and mouth, preventing particles from entering the wearer's respiratory system.
Key features of Level 3 face masks:
- ASTM F2100 Level 3 rating: This means they meet the highest standards for fluid resistance and barrier protection.
- High filtration efficiency: They filter out a high percentage of small particles, including bacteria and viruses.
- Fluid-resistant material: They are made from materials that resist penetration by fluids, such as blood and saliva.
- Adjustable nose bridge: They typically have an adjustable nose bridge to ensure a secure and comfortable fit.
- Earloops or ties: They are secured to the wearer's head with earloops or ties.
Examples of Level 3 face mask uses:
- Medical procedures
- Dental procedures
- Healthcare settings
- Laboratories
- Manufacturing environments
It is important to note that Level 3 face masks are not respirators and do not provide the same level of protection as N95 masks. They are best used in combination with other personal protective equipment (PPE), such as gloves and gowns, to provide comprehensive protection.
