![]() ![]() The main difference between ASTM F2100 level 2 masks and level 3 masks is that level 3 (high protection standard) has higher requirements for synthetic blood penetration resistance. ASTM F2100 level 2 and level 3 require masks that block at least 98% of bacteria and particles, with a differential pressure of just under 6.0mm H 2O/cm 2 (49.03 Pa/cm 2), which is a little more lenient than the lower protection level, because it is harder to maintain breathability while achieving better protection. FDA mask certification basically follows the ASTM F2100 standard.įDA mask certification requires the ASTM F2100 level 1, 2, and 3 surgical masks to meet relevant standards in four areas: bacterial filtration efficiency (BFE), particle filtration efficiency (PFE), synthetic blood penetration resistance, and differential pressure.ĪSTM F2100 level 1 mask can block 95% of bacterial and particles, even if only ASTM F2100 level 1 protection is achieved, it is sufficient for general protection. government in the Department of PHS (Public Health Service) under the DHHS (Department of Health and Human Services). FDA is the abbreviation of Food and Drug Administration, one of the executive agencies of the U.S. What are the performa nce require ments for ASTM F2100 level 1, level 2, and level 3 surgical masks?ĪSTM F2100 is the current standard for medical masks in the U.S. Protective clothing worn by medical personnel is used for similar purposes as masks and can effectively protect health care workers and patients from the accidental spread of disease. protective clothing and maskĬompared to non-level masks such as homemade cotton masks, the ASTM F2100 level 1, level 2, and level 3 masks will provide better protection against aerosols emitted by the wearer, thereby reducing the spread of disease. The higher the risk, the higher the level of protection mask should be chosen. Wearing a surgical mask of ASTM F2100 level 1, level 2, and level 3 not only prevents the spread of bacteria to the patient through the mouth and nose but also protects you from infection. The higher the level, the better the protection performance.ĪSTM F2100 level 1 and level 2 masks are usually called procedure masks while ASTM F2100 level 3 masks can be used in the operating room and are also called surgical masks. The ASTM F2100 standard is a medical standard that classifies masks into three levels: low protection (Level 1), medium protection (Level 2) and high protection (Level 3).
