Web8 mrt. 2024 · HEPA filters are used in laboratories that require high clean air standards. The rating for a HEPA filter is based on capturing nearly all microns 0.3 in size, versus 0.1 or even 0.001 because 0.3 microns are the hardest size to trap and the optimal size for passing into the human respiratory system. WebFilters with MERV ratings higher than 14 would capture an even higher percentage of the particles of concern. High-efficiency particulate air (HEPA) filters are even more efficient at filtering human-generated infectious aerosols. By definition, a HEPA filter must be at least 99.97% efficient at capturing particles 0.3 µm in size. change verify code cprs
