Abstract
A method of determination of the conditions of exhaustion of a filtering cartridge for filtering carafes with replaceable cartridges is described, in which an initial identification of impedance of the water to be filtered is provided for in order to consequently calculate an important parameter for definition of the efficient lifespan on the filtering cartridge. Furthermore a carafe operating in compliance with such method is also described.
