The Mi Water Purifier 1A was designed as a compact device suited for installation in kitchen cabinets. This is achieved by means of an innovative construction through which the complex water pipe system is accommodated in only one component; PP filter cotton and activated carbon pre- and post-filters are integrated in one cartridge. By means of a powerful reverse osmosis membrane, 99 per cent of pollutants are extracted from the water. Operating status, water values and other data can be accessed by means of an app.
