The Waterfall, designed for small to medium-sized households, is a water purifier for installation under the sink. It is fitted directly to the mains water and cleans it by reverse osmosis. While being treated, the water flows downwards as in a waterfall. A drop-shaped element treated with acrylic is integrated in the top of the device, clearly indicating the status of the purifying process. The motor comes separately, which saves space and eases configuration. The rotary filter cartridges are energy-saving and user-friendly.
