WHAT IS THE DIFFERENCE BETWEEN ASTM LEVEL 1, 2 & 3 SURGICAL MASK?
Each ASTM face mask has different performance levels, filtration and protection needs.
ASTM Level 1: low barrier protection are design for procedures with low amounts of blood, fluid, spray and/or aerosol exposure. Common clinical examples include patient exams, operatory cleaning, impressions, lab trimming and orthodontic work.
ASTM Level 2: moderate barrier protection are ideal for procedures where moderate to light amounts of fluid, spray and/or aerosols are produced. Level 2 masks are suitable for restoratives, prophylaxis, sealants, limited oral surgery and endodontic work.
ASTM Level 3: high barrier protection are for procedures with moderate to heavy amounts of blood, fluid, spray and/or aerosol exposure. High barrier protection is needed for procedures such as implant placement, crown preparation, and periodontal or complex oral surgery.
