FIELD: electret articles used for removal of aerosols from gases, especially from air. SUBSTANCE: proposed electret articles include polymer and additive enhancing efficiency; articles may be identified by their conductivity characteristics at thermal excitation or by their filtering properties. Such articles as non-woven filter cloths and respirators have perfect parameter of loading by oil mist, low permeability and low pressure differential. Electret articles are manufactured mainly by blowing from melt of mixture of polymer and fluorine-containing additive selected from group consisting of compounds of formulae (I), (II) and (III). 
EFFECT: enhanced efficiency. 30 cl, 19 dwg, 16 tbl, 23 ex
