HEPA_2 filter has the smaller fiber diameter than HEPA_1 and HEPA_3 filter. The lowest permeability constant was obtained by HEPA_2 filter. HEPA filters reached above 99% efficiency. Efficiency was evaluated for particles in the 7–289 nm range. HEPA_2 filter was highlighted when it was analyzed the cost benefit.
