Boiling water tap that also does cold water? What do you recommend?

Think we are having this Franke tap in our kitchen Franke Olympus. We have a water softener so this will be our main water supply in the kitchen.

We also need filtered drinking water (direct from the mains) so we may as well get a hot/cold filtered tap. Doesn't look like Quooker do that so what other make have MNs tried and liked? Thank you
