Leveluk K8: The Flagship Kangen Water® Machine

The Leveluk K8 (Kangen8) is the most advanced Kangen Water® machine in the lineup. Eight platinum-coated titanium plates — the most in any standard model — deliver the strongest negative ORP in the entire range, controlled through a modern touchscreen with voice guidance in ten languages. And despite being the flagship, it's as simple to own as any model we sell: a countertop unit you set up yourself, typically in under an hour.

• $5,890 + tax
• 5-year manufacturer warranty
• Financing available

*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.

The electrode plates are where electrolysis happens, and the K8 has eight of them — more electrolysis surface area than any other standard machine in the lineup. That extra surface area shows up in two ways: the strongest negative ORP in the range (up to −722 mV\*), and steady, consistent performance even at higher flow rates — filling large bottles, cooking pots, or running continuously for a busy household.

The K8 is the only model in the lineup with a full touchscreen. Selecting water types, checking filter life, and switching languages all happen on one clear color display — no memorizing buttons. If you've ever felt that water ionizers look like machines from another decade, the K8 is the exception.

The K8 speaks English, Japanese, Spanish, French, German, Italian, Portuguese, Chinese, Vietnamese and Arabic — it confirms your water selection out loud, so there's never a question about which water is flowing.

The K8 features a universal power input with multi-voltage support (100–240 V). It adapts automatically to different electrical standards, so it can be used anywhere in the world without a special regional configuration or a voltage converter — only a simple plug adapter for the local outlet. Within the lineup, this is a feature shared only by the K8 and the SD501DX; the JRIV, SD501U, and Super501 are built for the voltage of the country they're purchased in. If you relocate, travel for extended periods, or split time between countries, the K8 goes with you.

More capable doesn't mean more complicated. The K8 sits on the counter, connects to a standard faucet with the included diverter, and runs on a standard outlet — the same straightforward setup as every countertop model in the lineup. Cleaning is largely automatic, and the filter swaps out in seconds when it's due.

Like every Kangen Water® machine, the K8 produces five types of water across the 2.5–11.5 pH range, each selected with a tap on the touchscreen:

Every machine in the lineup produces these same five water types — what the K8 adds is the strongest electrolysis in the range. See [what plate count actually means](/compare-kangen-water-machines/) for the full breakdown.

* Measured ORP depends on your source water quality, mineral content, and flow rate. Official manufacturer specifications, subject to change — contact us for the current spec sheet.

The K8 uses the same DIY countertop installation as the other standard models — no plumber, no tools beyond what's in the box:

1. Place the K8 on the counter near your sink.

2. Connect the included diverter to your standard faucet.

3. Plug in, run the initial setup on the touchscreen, and you're producing Kangen Water® the same day.

Most customers are up and running in well under an hour.

Renting your home? The K8 needs no permanent installation and moves with you.

Owning a K8 is simple:

- Filter replacement — the touchscreen tells you when it's time; swapping the filter takes seconds. Frequency depends on your usage and source water.

- Electrolysis enhancer — used only when producing the strong waters (2.5 and 11.5); the machine prompts you when the tank needs a top-up.

- Cleaning — the K8 runs automatic self-cleaning; periodic deep cleaning service is available and recommended depending on your water hardness.

When you purchase your K8, an owner account is set up in your name — replacement filters and enhancer can be reordered any time through that account in a few clicks, shipped directly to you. Deep cleaning and any repairs are handled by the manufacturer's official service center, so your machine is always serviced by the people who built it.

The K8 is the right choice if:

- You want the top of the range — the strongest ORP capability (up to −722 mV\*) and the most plates in a standard model

- You prefer a modern touchscreen over physical buttons

- You have a family or higher daily water use and want performance headroom

- You may move, travel, or live abroad — the universal 100–240 V input means the machine works anywhere in the world

- You'd rather buy once: there's no upgrade or trade-in program, so if the flagship is within reach, starting with it means never wondering whether you should have

Consider a different model if:

- You prefer the proven 7-plate platform with physical controls → the [Leveluk SD501DX](/kangen-water-machines/leveluk-sd501dx/), the successor to the long-running best-seller

- You're a household of 1–2 with lighter daily use → the [Leveluk JRIV](/kangen-water-machines/leveluk-jriv/), the most affordable model in the lineup

- You want the machine hidden under the sink → the [Leveluk SD501U](/kangen-water-machines/leveluk-sd501u/)

- You're serving 6+ people or a business → the [Leveluk Super501](/kangen-water-machines/leveluk-super501/)

Leveluk K8: $5,890 + tax. The price is fixed by the manufacturer, so the K8 costs the same wherever you buy a new unit — no one can legitimately offer a "discounted" one. The difference is who you buy from: order through us and you have a direct contact you can email if a question ever comes up, before or after your purchase.

Financing options are available; see our [pricing & financing page](/kangen-water-machine-price/) for current plans.

Every K8 we sell is a brand-new, genuine unit with the official 5-year manufacturer warranty.

How much does the Leveluk K8 cost?

$5,890 + tax. It's a fixed manufacturer price, so there are no legitimate discounts on a new K8 (be cautious of "deals" that claim otherwise). Financing options are available — see our [pricing & financing page](/kangen-water-machine-price/).

Do I need a plumber to install the K8?

No. The K8 is a countertop unit that connects to a standard faucet with the included diverter — set it by the sink, connect, plug in, and most customers complete setup themselves in under an hour.

What is the K8's ORP, and why does it matter?

The K8 produces the strongest negative ORP in the lineup — up to −722 mV. ORP (Oxidation-Reduction Potential) is a measurable indicator of the water's antioxidant potential; the more negative the reading, the stronger it is. Actual measurements vary with your source water quality, mineral content, and flow rate.

What's the difference between the K8 and the SD501DX?

Both produce the same five water types, share the universal 100–240 V power input, and carry the same 5-year warranty — the K8 is simply the more capable machine. It has 8 plates to the SD501DX's 7, reaches a stronger ORP (up to −722 mV vs −631 mV\*), holds its performance better at higher flow rates, and replaces physical buttons with a color touchscreen. The SD501DX is an excellent machine and the right fit for many households; the K8 is for those who want the strongest electrolysis and the most refined interface in the lineup — and, since there's no upgrade or trade-in program, for those who'd rather start at the top than buy twice. [See the full side-by-side comparison here](/compare-kangen-water-machines/).

Can I use the K8 outside the country I buy it in?

Yes. The K8 has a universal 100–240 V power input that adapts automatically to local electrical standards, so it works anywhere in the world — you only need a plug adapter for the local outlet, not a voltage converter. This is a feature of the K8 and the SD501DX only; the other models in the lineup are built for the voltage of the country where they're purchased.

What languages does the K8's voice guidance support?

Ten: English, Japanese, Spanish, French, German, Italian, Portuguese, Chinese, Vietnames and Arabic.

How often do I need to replace the K8's filter?

It depends on your usage and source water — the K8 tracks filter life automatically and shows a replacement notice on the touchscreen when it's time. Replacement takes seconds, requires no tools, and filters can be reordered through your owner account.

Is the K8 suitable for renters?

Yes. It requires no permanent installation — it sits on the counter, connects to the faucet, and moves with you when you do.

The K8 is the strongest, most refined machine in the lineup — and just as simple to own as any other. Order with confidence, or ask us anything first; no pressure, just guidance.
