Governments across the world have different testing standards and certification processes for mouth-nose PPE like face masks and respirators. Not all masks provide the same amount of protection; to ensure adequate defense from fluids and particulate matter for the task at hand, knowing what certifications to look for is the key. Follow our guide to see what mask is the right choice for your team.
ASTM rated masks for the United States
For those located in the United States, an ASTM-rated mask is the best choice for protection. These masks are tested using the ASTM International test method who sets forth a preferred international standard for materials used in healthcare that covers testing and requirements for material performance. As recommended by the federal government (Federal Food & Drug Administration), the masks are tested in five key performance areas:
• Differential pressure
• Bacterial filtration efficiency
• Particulate filtration efficiency
• Fluid resistance
• Flammability
There are three levels of rating a mask can receive ranging from low (Level 1) to moderate (Level 2) to high (Level 3) protection.
