The newest of the filters in the Bosch range, the 644845 is distinguishable by two things - Firstly it fits horizontally in the fridge compartment as opposed to the older filter (which hangs vertically). Secondly, it has a very distinctive 'wave' around its keyway which can be seen in the image, which is not often seen in this type of filter.
This cartridge should fit all Bosch KAD62, KA62 and K59 models, however, please check the notes above before purchasing to confirm this is the correct model for your fridge. Note it will also fit Siemens KA62 series and Neff K5930 and K5920.
Cartridge life: 6 months
