Filtration / Disinfection - ASHRAE

High Efficiency Particulate Air (HEPA) Filters. By definition, HEPA filters are at least 99.97% efficient at filtering 0.3 μm mass median diameter (MMD) particles in standard tests. Most penetrating particle size may be smaller than 0.3 μm, so filtration efficiency of most penetrating particles can be slightly lower.

Understanding Filtration Efficiency: PFE, BFE, and VFE

28/06/2021· Virtual filtration efficiency (VFE) is nearly identical to PFE and BFE. The biggest difference is that a specific virus is used in aerosol form instead of bacteria or particulates. VFE is exceptionally important in high-grade medical masks when blocking out viruses like COVID-19, influenza, and others is incredibly crucial.
