Use mask types in Fluid MaskĬlick through to watch this video on This is a basic tutorial that will familiarize you with the software workflow. They need to be relatively non-flammable and easy to breathe in.In this tutorial you'll be introduced to the three mask types and the tools we use to apply them in the Fluid Mask software. Here is the filtration efficiency for the three levels of ASTM ASTM level 1ĪSTM masks are also rated based on flammability and breathability. If the BFE is ≥95%, then it means the mask can filter 95% or more of all sub-micron particles (≥0.1 micron) that pass through the mask. PFE shows the percentage of sub-micron particles (≥0.1 micron) the mask can filter. If the BFE is ≥95%, then it means the mask can filter 95% or more of all bacteria that pass through the mask. The second important factor to consider when choosing a level is how much filtration efficiency you want.įiltration efficiency is measured by two standards, BFE which stands for bacterial filtration efficiency, and PFE which stands for sub-micron particulate filtration efficiency.īFE shows the percentage of bacteria the mask can filter. ![]() Wearing an ASTM-rated mask already decreases the risk of other people’s fluids getting into your nose and mouth, but a higher-level mask can offer higher fluid resistance. The minimum fluid velocity each level of mask is resistant to is: In the lab, a set volume of synthetic blood is projected at the mask at various velocities to test its fluid resistance. The most important thing to consider when it comes to choosing level 1, 2, or 3 is how at-risk you are at being contaminated by the splashes, sprays, and aerosols of other people’s body fluids (such as blood and respiratory emission).ĪSTM-rated masks’ ability to resist fluid penetration increase with their rated levels. ![]() If a mask is labeled ASTM-rated, then it has been tested in a laboratory to prove that it fits the technical standards set forth by ASTM International. government.ĪSTM F2100-11 is the standard specification for the performance of the material used in medical face mask. ASTM’s standards are referenced by the FDA and endorsed by the U.S. that sets and defines technical standards for a wide range of materials, products, services, and systems. Now known as ASTM International, it is a 120-year-old global organization based in the U.S. MOCACARE Has FDA-Authorized ASTM-rated Medical Masks On Sale!ĪSTM stands for the American Society of Testing and Materials.
