Our well water is extremely hard and above the maximum recommended limits for several substances. The berkey filter we were using wasn't doing enough, as we could see in the kettle full of minerals after a single cup of tea.
This simple, small, and effective RO filter was easy to set up and has dramatically improved our water. Instead of measuring about 600 parts per million, the display is showing 3 parts per million, and the water tastes great after remineralization and spinning around in a vortex with mint or another infusion. Never loved water so much (except for wild springs).
Thank you for creating an affordable unit suitable for renters in small spaces!
