The filter classes are defined based on the efficiency of separating MPPS. In Europe, particulate air filters are differentiated into three groups: Overview of filter classes, incl. relevant degree of efficiency: EPA High-efficiency particulate air filter (= group E) HEPA High-efficiency submicron particulate air filter (= group H) ULPA Ultra low particulate air filters (= group U) 85% Efficiency 99.999995% E10 U17 The coronavirus is approx. 0.12 – 0.16 µm in size, which is within the effective range of an H14 filter in accordance with EN 1822. ! Filter classes Integral value Average value over the entire filter surface Local value Point value at the weakest part of the filter Efficiency (%) Penetration (%) Efficiency (%) Penetration (%) E10 ≥ 85 ≤ 15 E11 ≥ 95 ≤ 5 E12 ≥ 99.5 ≤ 0.5 H13 ≥ 99.95 ≤ 0.05 ≥ 99.75 ≤ 0.25 H14 ≥ 99,995 ≤ 0,005 ≥ 99,975 ≤ 0,025 U15 ≥ 99.9995 ≤ 0.0005 ≥ 99.9975 ≤ 0.0025 U16 ≥ 99.99995 ≤ 0.00005 ≥ 99.99975 ≤ 0.00025 U17 ≥ 99.999995 ≤ 0.000005 ≥ 99.9999 ≤ 0.0001 Efficiency: Percentage of particles separated / penetration: Percentage of particles that pass through the filter
