Henry Schein’s Ear Loop Procedure Face Masks are latex-free, light, comfortable masks for extended wear. The ear loops are made from special stretch yarn, so no irritating rubber or plastic touches skin. The masks’ 3-ply, glass-free filter media is surrounded by soft, nonirritating inner and outer facing, and the full-width flexible nosepiece provides fit and security. Henry Schein’s Ear Loop Procedure Face Masks are manufactured to exceed all current ASTMF 2100-03a standards.
