The invention relates to the field of water treatment, in particular to water purification in household conditions.A filter element is proposed for water purification, containing in the first and the last layer expanded highly porous polypropylene with the pore dimension from 0,2 up to 100 ?m, a sorbent layer and ion-exchange materials. As sorbent is used iodine-modified activated coconut coal, with iodine index of 1000...1100 mg/g, and as ion-exchange materials is used cationite on base of sulphonic acid and anionite on base of dimethylamine with the exchange capacity of 2,0 eq/L and 1,2 eq/L, respectively, the layer sequence being: iodine-modified activated coconut coal , cationite and anionite, where each layer is separated from the following one by a layer of expanded highly porous polypropylene. The result of the invention consists in the water softening, purification thereof from microorganisms, organic and inorganic inclusions.
