A water purifying apparatus of compact construction. The water purifying apparatus has a water channel for receiving water via an inflow passage and discharging water via an outflow passage. An electrically conductive filter is disposed in and fully occupies a portion of the water channel for purifying water flowing through the filter. A first electrode is electrically connected to the filter, and a second electrode, disposed in the filter, is electrically connected to the filter via water flowing through the filter. A battery supplies voltage between the first and second electrodes. A switch controls application of the voltage from the batteries to the first and second electrodes. A circuit board having a control circuit is disposed above the first electrode, the second electrode and the switch. The circuit board is electrically connected to the various electronic components.
