ASTM International is an organization responsible for ensuring certain manufacturing standards are met for products across the globe. An ASTM Level II mask means our marks are certified for use in many medical and industrial applications and are guaranteed to meet the following minimum requirements:
A minimum of 120 mm Hg resistance to liquid pressure before penetration occurs (I.E. how waterproof the mask is)
< 5.0 differential pressure measured in mm H20/cm^2 (I.E. how breathable the mask is)
≥ 98% efficiency in bacterial and microbial filtration
≥ 98% efficiency in filtering sub-micron particulates as small as 0.1 microns
Class I flame rating (high flame resistance)
