FIELD: purification of drinking water.

SUBSTANCE: the invention is dealt with the field of purification of drinking water, in particular, with production of the drinking water with high organoleptic parameters in conditions of a domestic economy and may be used for fine purification of the tap water in household conditions. The method of purification of drinking water by a household pitcher type complete set of a provides for ozone treatment of a portion of the subjected to purification water and its purification in a layer of a sorbent, in the capacity of which they use an activated charcoal as particles and-or a mixture of these particles with the ion-exchange resin. Ozone treatment of the portion of the water is exercised during the portion of the water passing through directly a layer of sorbent. At that the integrated purification of the portion of the water by ozone and the sorbent is conducted as the water is in a static mode in the layer of the sorbent and during the whole interval of time till the following portion of the treated water is fed in the given layer of sorbent.
