A home water monitoring device that tests and filters water. It has three significant over its competitors: firstly, it provides real-time monitoring of critical water quality parameters using microfluidic and mini-spectrophotometry sensor technology and analysis algorithms. Secondly, it has a high-efficiency compound filter using activated carbon fiber and ion exchange fiber. Thirdly, it has led indicator lights and an app that allows users to monitor water quality changes before and after filtration.
