Water N is a self-generated device which means you do not always need to provide electricity. It operates from the power generated by itself.

Users get information that helps them determine the type of water they use. You can check water’s temperature, quality, usage history, and more via its dedicated app. 

Water N is a one-time Installation where you can plug and use it for 365 days. You don’t have to repeat the installation process for 265 days. After installing, users can use Water N for about 7 years. So monitor your water and its temperature by simply looking at the LCD display without worrying about any replacements. 

It has become a CES 2023 Innovation Award Honoree in the Smart Home category.

SMT Water Filter and its Features

SMT Co., Ltd implemented an advanced monitoring device that provides accurate information in real-time. As a result, you can check water quality instantly. Moreover, its temperature monitoring is also very accurate. Users can use this feature to check out their favorite water temperature.

Since tap water can contain harmful particles, you must ensure its quality. Water N has a built-in UV LED function that sterilizes the filter using ultraviolet rays. 

The shower filter that exclusively comes with Water N has its own benefits. Its main highlight is effectively removing harmful particles and other residues.  

Water N comes with Bluetooth compatibility, which brings more connection options. It allows users to monitor the Water N device through their smartphone directly. As a result, users can monitor the quality and temperature of water from anywhere in the house.

There are five levels of water quality that Water N shows in its display. These levels are shown as a status: Bad, Poor, Fair, Good, and Very Good. Judging from the status, you can figure out the quality of your water. It is a simple yet intuitive way that helps anyone understand the state of their water. 

Water N also shows ppm emoji that showcases the number of solids dissolved in water. Usually, a ppm level that is less than 250 is considered good to very good. If it is higher, more solids are dissolved in the water.

When it comes to the eco-friendly ethics of the company, SMT is also great at that. It uses filters made from ECOZEN filters which are also commonly used for baby bottles. Its main benefit is that it helps users avoid environmental pollutants. Other cheap BPA filters contain harmful materials that generate such pollutants. So using an eco-friendly Water N filter is an incredible step from SMT.
