ASTM PROTECTION VS. INTENDED USAGE

LEVEL 1 (LOW) BARRIER: 80 mm Hg	LEVEL 2 (MODERATE) BARRIER: 120 mm Hg	LEVEL 3 (HIGH) BARRIER: 160 mm Hg
Light / minimum BFE & PFE protection	High BFE & PFE protection	High BFE & PFE protection
Used for general procedures and respiratory etiquette	More breathable than high barrier mask
Designed to resist a splash or spray at venous pressure	Designed to resist a splash or spray at arterial pressure	Highest fluid resistance – designed to resist a splash or spray during tasks like orthopedic surgery or trauma
