Which filter collect dust with high efficiency?

Most modern cell-processing facilities have ventilation systems with filtered air—using high-efficiency particulate air (HEPA) filters, a technology developed in the 1940s. HEPA filters have a minimum particle collective efficiency of 99.97% for particles of 0.3 µm diameter or more.
