Fluid resistance indicates how well a face mask can prevent fluid penetration, which is vital in environments where exposure to blood or bodily fluids is possible. ASTM levels (1, 2, and 3) denote increasing resistance, with Level 1 suitable for low fluid exposure and Level 3 for high-risk situations. Some masks specify their resistance in mm Hg, such as 80 mmHg for Level 1 or 120 mmHg for Level 2. The Cardinal Health AT73035 offers Level 1 protection, while the Precept 15900 and Medline NON24506A Cone-Style N95 provide higher fluid resistance for greater protection. With a range of ASTM levels and fluid resistance ratings, you can select a mask appropriate for your specific risk environment.
