A filter jug for purifying water for domestic use comprises a container (2) divided at least into a first compartment (8) and a second compartment (9) intercommunicating through a filter cartridge (11), and a first duct (12) and a second duct (13) for the admission and for the discharge of the water to the first compartment and from the second compartment (8, 9), respectively. Flow-measuring means (15) and counting means (14, 14a, 14b), associated therewith, are provided in the jug in at least one of the ducts (12, 13), for determining the total quantity of water treated by the filter cartridge (11) so as to identify the reaching of a limit quantity above which the cartridge should be considered exhausted.
