ASTM-Rated 3-Ply Surgical Masks

All disposable 3-ply surgical masks in the Project N95 shop meet standards set by The American Society for Testing and Materials (ASTM) and are rated level 3 for maximum barrier protection: 160 mmHg fluid resistance and at least 98% particle and bacterial filtration efficiency. 3-ply masks are popular for members of the general public who use many throughout the day or have difficulty fitting or breathing in a high-filtration mask.
