ASTM Level 3 masks and KN95 masks serve different purposes and are not directly comparable. ASTM Level 3 masks are designed for high-fluid resistance and are typically used in medical settings for surgical procedures, while KN95 masks offer a higher level of filtration efficiency and are designed to protect against airborne particles. The choice between them depends on the specific context and needs, such as fluid resistance or particle filtration.
