Kangen Water® Machines: The Complete Lineup

Every Kangen Water® machine is made by Enagic in Japan and produces the same five types of ionized water — what differs between models is capacity, electrolysis strength, features, and price. This page introduces the full current lineup so you can find the machine that fits your household, your kitchen, and your budget.

Each model below has its own detail page with full specifications. Want them side by side instead? See our [full comparison page](/compare-kangen-water-machines/).

*ORP (Oxidation-Reduction Potential) indicates the water's antioxidant potential — the more negative the number, the stronger it is. Actual measured values vary with your source water quality, mineral content, and flow rate.*

All prices are fixed by the manufacturer and are subject to change. Contact us for the current official price list. Financing is available on every model — see [pricing & financing](/kangen-water-machine-price/).

Highlight:

• 8 plates
• Up to −722 mV ORP*
• Touchscreen
• 8-language voice guidance
• 5-year warranty
• $5,890 + tax

The most advanced machine in the lineup. With eight platinum-coated titanium plates — the most in any standard model — the K8 delivers the strongest negative ORP in the lineup, controlled through a modern touchscreen. A simple countertop unit you can set up yourself: place it by the sink, connect to the faucet, done.

Choose the K8 if: you want the top of the range — maximum electrolysis strength and the most refined interface.

Highlight:

• 7 plates
• Up to −631 mV ORP*
• Simple Button + Large LCD Display
• 8-language voice guidance
• 5-year warranty
• $5,360 + tax

The direct successor to the legendary SD501 — Enagic's best-selling machine for over a decade — now with an updated body and improved features. Seven plates, all five water types, and the same simple DIY countertop setup. For most households, this is the natural starting point.

Choose the SD501DX if: you want the most proven platform in the lineup at a lower price than the flagship.

Highlight:

• 7 plates
• Up to −631 mV ORP*
• Under-sink unit
• Wall-mounted control panel
• 5-year warranty
• $5,890 + tax

The same 7-plate performance as the SD501DX, designed to stay out of sight: the machine installs under the sink, with only a sleek control panel mounted on the wall above. The trade-off is installation — it requires drilling, mounting, and dedicated plumbing work, so we recommend hiring a licensed plumber (arranged by the customer).

Choose the SD501U if: you want a clean, clutter-free counter and don't mind a professional under-counter installation. Renters should generally choose a countertop model instead.

Highlight:

• 12 plates (7+5 twin chambers)
• Up to −600 mV ORP*
• 3-year warranty
• $7,080 + tax

Built for volume. Twin electrolysis chambers keep output steady through heavy, continuous daily use — big families, or settings like cafés and studios that serve many people. Note that while it sits on the counter, it's a larger, heavier unit with a more advanced setup than the standard models, so we recommend professional installation by a licensed plumber (arranged by the customer).

Choose the Super501 if: you have 6+ people to serve, or light commercial needs.

Highlight:

• 4 plates
• Up to −450 mV ORP*
• LCD Display
• 3-year warranty
• $3,530 + tax

The lowest-priced way into the lineup. Four plates produce the same five water types as the bigger machines, with lighter electrolysis strength that suits singles, couples, and lighter daily use. It's a countertop unit with the same straightforward DIY setup as the K8 and SD501DX — place it by the sink, connect to the faucet, and you're ready.

Choose the JRIV if: you're a household of one or two, or you want genuine Kangen Water® at the lowest entry price.

However they differ in capacity and strength, all five machines share the same foundation:

• The same five water types across the same pH range (2.5–11.5) — from strong acidic to strong alkaline, including clean filtered drinking water.
• Platinum-coated titanium electrode plates — the core of every machine in the lineup.
• Made in Japan by Enagic, with an official manufacturer warranty on every unit we sell.
• Built-in filtration with replaceable filters, so upkeep is straightforward.

What plate count changes is the strength of the water (negative ORP) and the capacity of the machine — not the variety. For the full breakdown, see [what plate count actually means](/compare-kangen-water-machines/).

Enagic has discontinued the Leveluk SD501 and SD501 Platinum and replaced them with the [Leveluk SD501DX](/kangen-water-machines/leveluk-sd501dx/) — the same proven 7-plate core in an updated body with 8-language voice guidance. Existing SD501 and SD501 Platinum machines remain fully supported with filters and service; [contact us](/contact/) if you need help with an existing unit.

A quick shortcut:

- 1–2 people, or the most affordable option → JRIV

- Most households (3–6 people) → SD501DX

- Want the absolute best → K8

- Want the machine hidden under the sink → SD501U

- Big family or business use → Super501
