We’ve been using the British Berkefeld with the ultra fluoride filters for a little while now and honestly it’s been great. I feel better knowing it takes out nasty fluoride since I’ve got young kids and that’s super important to me and the water tastes really clean, way better than before and the unit itself looks nice on our counter in the kitchen. Flow could be a bit faster but no big deal since we let it filter overnight. Definately worth it for peace of mind.

I’ve been using the British Berkefeld system for about a month now and I’m honestly impressed. The setup was simple, and the water tastes noticeably cleaner and fresher like no chlorine smell or weird aftertaste. I was skeptical at first, but after reading about the independent testing and the fact that the filters are ceramic (not plastic-heavy), I felt more confident in the purchase. It’s been a great addition to our kitchen, especially living in an area with heavily treated municipal water. Highly recommend if you want peace of mind without relying on bottled water.
