Filtration / Disinfection - ASHRAE

By definition, true HEPA filters are at least 99.97% efficient at filtering 0.3 m mass median diameter (MMD) particles in standard tests. Most penetrating particle size may be smaller than 0.3 m, so filtration efficiency of most penetrating particles can be slightly lower. HEPA filter efficiency is ASTM F2101 - 19 Standard Test Method for Evaluating the , standard disposable filtration efficiencyF2101-19 Standard Test Method for Evaluating the Bacterial Filtration Efficiency (BFE) of Medical Face Mask Materials, Using a Biological Aerosol of Staphylococcus aureus medical face masks~ Staphylococcus aureus~ bacterial filtration efficiency~Filtration Efficiency - an overview | ScienceDirect TopicsIn filtration of particle sizes with submicrons, the same filter efficiency can be achieved at a lower pressure drop with smaller fiber sizes, or conversely, better filter efficiency can be achieved at the same pressure drop [39]. For nanometer-scale fibers, the effect of the slip flow at the fiber surface has to be taken into account.
