What do ASTM Levels Mean?

ASTM International determines the face mask level of protection based on key performance factors that are vital for effective infection control: 

  • Bacterial Filtration (BFE)
  • Particle Filtration (PFE)
  • Fluid Resistance
  • Differential Pressure
  • Flammability

All BeeSure face masks offer at least ASTM Level 2 protection which means they provide >98% bacterial and particle filtration efficiency at 0.1 micron and 120 mmHg fluid penetration resistance.
