16/3/2016, · Standard specification for performance of materials used in medical face masks. F2100-11 Standard. ASTM Level 2 mask used during dental hygiene prophylaxis. The BFE and PFE are important criteria used to distinguish the three ASTM mask levels.
Protecting against high bacterial infiltration, Level 3 masks feature a 4-ply design with a fluid resistant outer layer. These masks are available in blue, pink, and white. In addition, Level 3 is available as a blue mask with shield. New DEFEND Level 1, 2 and 3 Face Masks are available through most dental dealers.
The filtration efficiency and protective ability of a ,face mask, is compromised when the ,mask, becomes wet, torn or dislodged. Generally speaking, the higher ,protection, value of a ,mask, the longer it will maintain filtration; however, there is no set rule for how long a ,mask, should be worn as it depends on humidity ,levels,, respiration rate, nasal discharge, talking, etc.
Therefore, CDC does not recommend using ,masks, for source control if they have an exhalation valve or vent. ,Face, Shields. A ,face, shield is primarily used for eye ,protection, for the person wearing it. At this time, it is not known what ,level, of ,protection, a ,face, shield provides to people nearby from the spray of respiratory droplets from the wearer.

Level 2: Ideal for procedures where low to moderate amounts of fluid, spray and/or aerosols are produced. Click here for ASTM Level 2 …
easy for your staff to get the ideal face mask for any procedure-and for every preference. Measuring fluid resistance, filtration and breathability, ASTM categorizes masks into three levels. ASTM Level 1 For procedures producing low amounts of fluid, spray and/or aerosols. ASTM Level 2 For procedures producing light to moderate amounts
Level 1: Low barrier protection . General use. Not used for aerosols, spray or fluids. Level 2: Moderate barrier protection . For low to moderate levels of aerosols, spray and/or fluids ; Level 3: Maximum barrier protection . Used for high risk of fluid, spray or aerosol exposure ; Testing Metrics: Masks are tested to five criteria: Bacterial Filtration
But not all ,masks, confer equal ,levels, of ,protection,. The ideal ,face mask, blocks large respiratory droplets from coughs or sneezes – the primary method by which people pass the coronavirus to others – along with smaller airborne particles, called aerosols, produced when people talk or exhale.
