Leveluk SD501 is the most popular home model, and the perfect machine for you and your family. This industry-leading machine conveniently connects to your kitchen faucet and generates enough of the 5 types of Enagic® water (see below) for you to share with your community and loved ones. Although it is incredibly powerful, the SD501 is also very compact and perfectly suitable for your kitchen cabinet. The fully featured LCD screen is attractive and simple to operate. The SD501 is Enagic's "Flagship" model because it provides additional stable oxygen and higher negative ORP levels. Like all 501 models, the SD501 uses innovative electrolysis technology with 7 platinum-coated 99.97% pure titanium electrode plates.
