The AcalaQuell Mini is more than just a water filter system. It is a complete, yet compact water treatment system. The water preparation follows the principles of nature combined with the results of intensive R&D. The multi-layered filtration ensures the highest water quality. Developed in Japan and Germany PI-water preparation technology gives your drinking water the qualities of natural spring water! Since no pressure is exerted on the water, it has time to unfold like a good wine. The water is then stored in a crystal glass tank with a capacity of 5 litres. You can add mineral stones into this tank which can make the water taste more aromatic or softer. The mineral stones also enrich the water with essential minerals for the body and also affect the alkalinity.
