Masks are NOT all created equal. There is a difference. DO NOT BE PENNY WISE AND DOLLAR FOOLISH. Please be smart when purchasing face masks. The American Society For Testing and Materials (ASTM) has statutorily defined mask levels and which mask should be worn in different procedures. Masks are grouped into level 1, level 2, and level 3.

Level 1 - Masks low barrier protection general use for short procedures and exams that don’t involve aerosols, spray or fluids. They are designed for procedures with a low amount of fluid, blood, aerosol exposure or spray. Examples include impressions, operatory cleaning, patient exams, orthodontic work, as well as lab trimming.

Level 2 - Masks are moderate barrier protection for low to moderate levels of aerosols, spray and/or fluids. They are suitable for procedures with light or moderate amount of blood, fluid, aerosols or spray are produced. Examples (for dentists) include sealants, prophylaxis, restoratives, endodontic work, and limited oral surgery. Just like level 1 masks, level 2 masks are also latex or fiberglass free.

Level 3 - Masks are maximum barrier protection for heavy levels of aerosols, spray and/or fluids. These masks are considered a high barrier. They are ideal for procedures with a moderate or high amount of fluid, blood, aerosols or spray exposure. Common procedures where level 3 masks are suitable (for dentists) include implant placement, complex oral surgery, and crown preparation.
