FIELD: filter materials. SUBSTANCE: filter material for respirators contains outer and inner protection layers and working layer of fibrous polymeric material made from mixture of perchlorovinyl and copolymer of styrene with methyl methacrylate and acrylonitrile, perchlorovinyl constituting 1-9 wt % or 91-99 wt % of mixture. Filter material is manufactured by electrostatic formation of nonwoven fibrous material from solution of the aforesaid polymers in dichloroethane. EFFECT: enabled manufacture of high-efficiency filter material with uniform structure involving more feasible process. 5 cl, 1 dwg
