The MI Water Purifier combines a purist outer case with a complex water purifier system inside. By means of a reverse osmosis filter with a filter capacity of about 1,500 litres, it extracts pollutants from mains water. The filtered water is available within a few seconds so that a storage tank is unnecessary. All information on water quality, filter capacity etc. can be retrieved via a smartphone app. The appliance can be easily connected to existing water and power connections.
