ASTM-Rated 3-Ply Surgical Masks
3-ply surgical masks must meet standards set by The American Society for Testing and Materials (ASTM) and are rated level 2 or 3 for maximum barrier protection: At least 98% particle and bacterial filtration efficiency and a minimum of 120 mmHg fluid resistance. 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.
The nonprofit Project N95 shop has closed. It has been our honor to serve during this moment in history. Thank you for being a part of our journey.
To help you access highly-protective, authentic masks, we have maintained a list of products that we previously vetted. Each item has a link to a third-party website—not controlled or operated by Project N95—where you can purchase these products. These links are current as of January 31st, 2024.
