The present invention is a water filter pitcher equipped with a removable, replaceable filter cartridge and means to count the number of times the pitcher is filled with water, and also means to notify the user when the pitcher has filtered enough water to exhaust the filtering capacity of the filter cartridge so that the user can replace the filter cartridge when necessary but does not have to remember to change the cartridge at a specific interval or count the number of gallons filtered manually, and instead can rely on the water filter pitcher to track the amount of water filtered and inform the user when to change the filter cartridge.
