초록

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.

청구항

The invention claimed is: 1. A method comprising: providing a filtering carafe with a replaceable filtering cartridge; calculating a parameter using a determination of impedance of water to be filtered; and determining a lifespan of the filtering cartridge using the parameter. 2. The method according to claim 1, in which said determination of impedance is carried out in water filtered by the cartridge. 3. The method according to claim 1, in which determining the lifespan of the filtering cartridge further comprises consideration of at least a secon...
