FIELD: breathing apparatuses. SUBSTANCE: filter medium for breathing apparatuses is obtained by way of electrostatic forming of unwoven material from polymer solution in organic solvent; ethylene dichloride and/or chlorinated polyvinyl chloride are taken as polymer, and ethylene dichloride is taken as solvent; forming is carried out at a solution dynamic viscosity within 0.5 to 35 poises, conductivity 10-4-10-7 at volumetric feed rate of solution 10-4-20-2 and potential difference within 10 to 70 K per spinning element. EFFECT: facilitated procedure. 2 cl, 1 tbl
