ABSTRACT:
An air filtering apparatus for electrolyzing water in an electrolytic bath by applying a voltage between electrodes in the electrolytic bath, supplying the generated electrolytic water to a gas-liquid contact member and blowing air to the gas-liquid contact member to filter the air, including a scale removing unit for inverting the polarities of the electrodes to remove scale deposited on the electrodes, and a judging unit for judging on the basis of a current value flowing between the electrodes whether the scale is removed from the surface of the electrode.
