The casing of apparatus for purifying water encloses a chamber and is formed with two orifices spaced from the chamber in opposite directions and communicating with the same for gravity flow of the water to be purified from one of the orifices through the chamber and out of the other orifice. Two electrodes spacedly mounted in the chamber for flow of the water therebetween are conductively connected to an electric battery in the casing by circuitry which causes current to flow between the electrodes through the water when the water and the battery satisfy proper conditions for the functioning of the apparatus, such conditions being indicated by a sensible signal. A compartment in the casing, sealed from the electrode chamber, encloses almost all the circuitry.
