Want an advanced water filter system but don’t want to deal with messy hoses, leaky diverter valves, and clunky installation? Meet U1 by RKIN.

It’s a sleek, zero-installation water filter that uses reverse osmosis, UV, and hydrogen technologies to transform ordinary tap water into pure, healthy, and delicious drinking water.

It has an advanced filtration system that’s made up of five stages to give you the purest, most delicious drinking water imaginable, unlike other water filter 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.

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.

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.

With a pre-order of U1, you get an unconditional 1-year money-back guarantee.

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!

U.S. backers will also be responsible for the optional turntable shipping cost (approximately $12) after the campaign ends.
