Water N 3
Water N 3 is the world’s first self-powered purifier that uses hydroelectric power from its own running water. Our powerful IoT capabilities allow us to also be the first to offer real-time water quality updates and accurate filter replacement alerts.
This ensures you avoid wasteful underuse or potential health risks from overused filters.

Lets you measure the water quality and temperature anywhere in your house
Features Bluetooth connectivity, which lets you read the water quality and temperature remotely on the Water N 3 application.
You never have to worry about replacing batteries because of our self-powering device. The direct-tap water purifier is fueled by hydroelectric power from the water that runs through it, and we were able to achieve self-generation efficiency even under low water pressure through our hydrodynamic mechanism design.
Typical home drinking water purifiers require hazardous batteries or a power source to operate, and because replacing water filters is time-based (i.e. change every 3 months), you actually have no idea if you are underusing or harmfully overusing your filters

01
Exact ppm&NTU levels are displayed on the Water N 3 application.
Accurately measured water quality and temperature in real time is displayed on an easy-view LCD.
The water quality is displayed as "Very Good," "Good," "Fair," "Poor," and "Bad."
You can check the precise ppm level through the Water N 3 application.
What is ppm?
ppm represents water quality by showing the amount of solid matter dissolved in water. The ppm level increases if the mass of a chemical or contaminate in the water increases.
What is NTU?
NTU stands for Nephelometric Turbidity unit, i.e. the unit used to measure the turbidity of a fluid or the presence of suspended particles in water. The higher the concentration of suspended solids in the water is, the dirtier it looks and the higher the turbidity is.

Economical and practical
You never have to worry about replacing batteries because of our self-powering device. The direct-tap water purifier is fueled by hydroelectric power from the water that runs through it, and we were able to achieve self-generation efficiency even under low water pressure through our hydrodynamic mechanism design.
Our product is not only less expensive than competing products, but it also saves money by eliminating the need for batteries or an external power source. We are the first water purifier on the market to offer this.
03
You can monitor water quality and temperature in real time anywhere in your house.
With embedded Bluetooth function, the water quality and temperature can be checked remotely in the Water N 3 application. The data is automatically saved in the Water N 3 app.
The app provides a history of water quality and temperature.
It lets you see the changes in water quality as well as the ideal filter replacement cycle for your home.
We provide a personalized IoT solution service by providing information that the user needs through the Water N 3 app.
04
It provides healthy water consumption through a powerful three-stage filter and UV purification system.
LED indicators for water quality and filter replacement timings are clearly visible on the front of the device, and can also be viewed on our mobile app. Water is disinfected and impurities removed using UV light sterilization.
Our patented water purifier revolutionizes conventional ones, offering superior sustainability, cost savings, and healthier water consumption compared to outdated alternatives.
05
Our patented water purifier offering superior sustainability, cost savings, and healthier water consumption compared to outdated alternatives.
Typical water purifiers’ filters are replaced based on time - manufacturers instruct customers to replace filters every month, 2 months, etc. However, changing filters strongly depend on local water quality and how often you use the purifier. Customers are constantly replacing filters too early - wasting money, or too late - resulting in drinking unclean water. Our technology gives accurate, real-time information on when to change filters, protecting health and saving money.
Also Water N3 provides water consumption information, recommended intake levels, and can also analyze water quality and usage to predict the filter lifespan and suggest the ideal filter type for each user.
