Which reverse osmosis system is the best?
Our water filter experts Niko and Benedikt wanted to know exactly that. So we sent them to our water filter kitchen to extensively test popular countertop, under-sink, and direct-flow reverse osmosis devices under real-world conditions.
In doing so, we didn't just look at the pure filtration performance. Each osmosis system was tested for installation, noise level, flow rate, maintenance effort, wastewater ratio, and suitability for everyday use.
It was important to us: not a laboratory test under ideal conditions, but an honest practical test – transparent, independent, and verifiable.
