ASTM Level 3 masks provide high fluid resistance and filtration efficiency, making them suitable for high-risk environments where exposure to blood, bodily fluids, and particulate matter is expected. They offer the highest level of protection among ASTM-rated masks, with a minimum bacterial filtration efficiency (BFE) and particulate filtration efficiency (PFE) of 98%.
