Replaceable cartridge filtering jug including a for containing water requiring filtration and a vessel for the collection of filtered water in which the vessels are connected through the cartridge together with a device for counting the filtering cycles performed by the cartridge to determine the state of exhaustion of the cartridge. The device for counting the filtering cycles includes at least one float level detector associated with one of the vessels and capable of generating at least one counting signal fed to a counter as a result of the corresponding water level being reached within the associated vessel. |
