HEPA filter rate is 0.3 micron at 99.97%.
This filter rate is 0.3 micron at 99.5%. There is 0.47% difference between this filter and HEPA filter. It is good enough for most industrial and home shop.
HEPA (high-efficiency particulate air) filter, also known as high-efficiency particulate absorbing filter and high-efficiency particulate arrestance filter, is an efficiency standard of air filters.
Filters meeting the HEPA standard must satisfy certain levels of efficiency. Common standards require that a HEPA air filter must remove—from the air that passes through—at least 99.95% (ISO, European Standard) or 99.97% (ASME, U.S. DOE)of particles whose diameter is equal to 0.3 μm, with the filtration efficiency increasing for particle diameters both less than and greater than 0.3 μm.
