A water purifying device that has a collecting jug for purified water, in which a funnel with a filter cartridge filled with purifying medium is fitted in a removable manner, the jug can be closed at the top with a lid. Grips for removing the lid are arranged on the lid, and an indicator is provided for indicating the exhaustion of the purifying medium. The indicator is inexpensive, easily readable and reliably functioning to show the state of exhaustion of the purifying medium. The indicator is secured in an aperture in the top surface of the lid, an indicator panel of which can be seen externally from above and which, by an electronic, battery driven circuit, shows only the respective state of time elapsed, without cooperating with separate signaling.
