USA-Made KN95 Face Mask Cleared
February 8, 2022
Lindon, Utah-based PuraVita Medical has received the FDA’s 510(k) clearance for its domestically made medical-grade KN95 face masks.
“Our KN95 masks are the only KN95s in the world that are FDA 510(k) approved, ASTM Level 3 and Made in USA,” the company said. ASTM Level 3 is the FDA's highest rating for medical and surgical face masks.
PuraVita was founded in 2020 specifically to produce high-quality face masks. The newly cleared KN95 masks cost just under $20 each.
