RKIN U1 Space-Saving 4-in-1 Water Filter System
Want an advanced water filter system?
But don’t want to deal with messy hoses, leaky diverter valves, or clunky installation? Meet the latest model of the U1 by RKIN with app-enabled features. Control and monitor your water system from your phone. This sleek, zero-installation water filter uses reverse osmosis, UV, and hydrogen technologies to transform ordinary tap water into pure, healthy, and delicious drinking water. It features an advanced five-stage filtration system to provide the purest, most refreshing water imaginable, unlike other systems on the market. Plus, you can choose your water’s temperature (hot or cold!), thanks to the temperature control system!
We want you to have the best quality water in your home…
That’s why U1 has an advanced filtration system with five stages. It removes up to 99% of all contaminants, including Fluoride, Chlorine, heavy metals like lead, and more.
Plus, U1 has an intelligent touch control panel, so you can easily see the status of your filter. It also has a UV Light that keeps water fresh when the system is not in use.
So, how does U1 Work?
1. Fill the water tank.
2. Place the tank on the system and let it do all the work.
3. Once your water is ready, select your temperature (hot or cold), and enjoy.
U1 doesn’t require installation, so you can easily place it on your countertop - perfect for people who live in apartments, condos, and RVs.
Customizable temperature
Do you ever wish your water filter system had hot or cold water?
U1 has a customizable default water temperature setting so that your water is always set to the temperature of your liking. Plus, there’s an instant hot water option that’s perfect for baby formula, tea, instant coffee, and more!
The display will also show the Hydrogen content and water quality readings, so you’ll always know your system is working properly.
Alkaline and antioxidant hydrogen-enriched water
U1 includes a polishing Alkaline post-filter that returns beneficial minerals, calcium, and magnesium to purified water for the best taste.
It also increases the alkalinity of the water to a perfectly balanced level of 7-8 pH, similar to spring water.
Plus, U1's hydrogen-infused water delivers a negative ORP of 340.
Smart control panel and RKIN app
You can monitor your filtered water quality and filter status with U1’s intelligent touch control panel or the RKIN app, regardless of whether you are nearby or miles away. The RKIN app is compatible with the NEW U1-W model only.
2-year filter bundle
If you opt to add our 2-year filter bundle to your order, you'll receive two annual replacement filter kits, two hydrogen PEM modules, and one reverse osmosis membrane.
You'll get three years of use with this add-on!
