Has anyone got a Franke Filterflow tap?

I love the idea of it but can't work out the cost of the whole system. I can see the taps are pretty expensive all on their own but can anyone tell me how much the filtration stuff is and how often the cartridge needs changing?

We have one. I had one in our last property too. I really like them. The cartridge is supposed to be changed (from memory every six months) but I change it much less frequently. I normally change it when the water flow decreases and it takes to long to fill the kettle. There are filter that aren't made by Franke that can be used instead and half the price. They're fine, the only downside is that the flow rate is slightly slower.
