I don't know the EU market other than what I can find on Amazon.
Is what I recommend for in home because it does allot for not that much. I don't know anything about that brand it just came up on my first search for a 3 stage. But that's what I would look for.
A 3 stage 10" is everything you need for home drinking water without getting insanely expensive for a salt system or RO. The size is good fit for under counter.
