Qi2
Qi2 is a modular water purifier designed for household use. The design is inspired by an array of bricks. Each filter cartridge forms part of the purifier body, so the combined cartridges create the complete unit. Users can select from one to five cartridges, including polypropylene, active carbon, ultraviolet, ultrafiltration and reverse osmosis types. Cartridges can be added, reduced or replaced with a simple tool. The waterway is replaced together with each cartridge, so the water path stays clean.
