Grohe Blue Home faucet or a comparable system

Or from the side-by-side with a pre-installed filter plus water softening system in the utility room.

Of course the kids drink from the French door. But I would like to offer sparkling water to guests.

Maybe there is still a solution that is cheaper in maintenance...

See my post on page 1. Sprudelux. No filter necessary if already in the house, regular commercial bottles. Energy consumption no idea. No subscription.

But no experience either...

With Sprudelux, I apparently have 2 "water taps" on the countertop...

No, the system is not tied to its own faucet like Grohe. You can also combine it with 5-way faucets. According to their website. But whether that's true and works like that – no idea.

I’m bringing the thread up again. Has anyone had experience with Sprudelux by now? According to reviews, Grohe doesn’t seem to sparkle very strongly.
