Tests determining the filtration efficiency for a bacterial test aerosol of Bacillus subtilis spores through filter cartridges of domestic materials and through filter cartridges where the principal filtering layer was an electrostatic material from Freudenberg company were carried out to determine the efficiency of purifying air from microorganisms using breathing filters. Tests of the breathing filters were prepared and carried out according to a procedure developed at the SRC FMBA of Russia. Spores of B. subtilis were elliptical and small (0.7 × 1.3 μm). Their concentration in the aerosol was (2.76-5.00)⋅107 spore/m3. The tests were carried out with linear filtration rate 17 cm/s.
