Quick Verdicts

Best overall for most households → Leveluk SD501DX

A well-rounded Kangen Water® machine for everyday household use, the SD501DX combines 7 platinum-coated titanium plates, five water types, up to −631 mV ORP, 8-language voice guidance, and a 5-year warranty in a straightforward countertop setup you can install yourself. If you're unsure where to start, start here.

Best premium pick → Leveluk K8

The flagship. Eight plates (the most in any standard model), the strongest negative ORP in the lineup (up to −722 mV), touchscreen controls, and 10-language voice guidance. For buyers who want the top of the range.

Best on a budget → Leveluk JRIV

The most affordable Kangen Water® machine in the lineup, the JRIV offers all five water types at a lower entry price. With 4 platinum-coated titanium plates and ORP readings up to −450 mV, it's best suited to singles, couples, and households with lighter daily water needs. A practical starting point if you want the full range of water types without paying for a higher-performance model.

Best for large households or business use → Leveluk Super501

Twin electrolysis chambers (7+5 plates) designed for higher daily water volume — suitable for large families and settings like cafés and studios that serve many people. Although it sits on the counter, the Super501 is larger and heavier than standard countertop models, and its more involved setup makes professional installation advisable.

Best for an Under-Counter Installation → Leveluk SD501U

The SD501U offers the same 7-plate configuration and up to −631 mV ORP capability as the SD501DX, while keeping the main unit beneath the sink and placing the control panel on the wall above. Installation is more involved than with the countertop models, so we recommend having a licensed plumber handle the setup.

Compare by What Matters to You

1. Household Size & Daily Volume

  • 1–2 people: JRIV covers lighter daily needs comfortably.
  • 3–6 people: SD501DX, SD501U, or K8 — all built for steady family use.
  • 6+ people or light commercial: Super501 is the lineup's high-capacity option for larger households and light commercial settings.

2. Plate Count — What It Actually Means

The electrode plates are where electrolysis happens. More plates means more electrolysis surface area — and that shows up in the water itself, in three ways:

A) Stronger negative ORP. ORP (Oxidation-Reduction Potential) is a measurable indicator of the water's antioxidant potential — the more negative the reading, the stronger it is. Plate count is the biggest factor here:

Model

Leveluk SD501U

Leveluk JRIV

Leveluk Super501

*Measured ORP depends on your source water quality, mineral content, and flow rate.

A note on the Super501: its 12 plates are split across twin chambers (7+5) designed for high-volume output, not stronger electrolysis — which is why its ORP sits near the 7-plate models rather than above the K8.

B) More stable performance at higher flow rates. More surface area keeps electrolysis consistent even when you're filling large containers or running the machine continuously.

C) Price. Plate count is the main driver of the price differences between models.

The bottom line: every model in the lineup — from the 4-plate JRIV to the 8-plate K8 — produces the same five water types across the same pH range. What changes with plate count is the strength of the water (negative ORP) and the capacity of the machine.

If maximum antioxidant potential matters to you, the Leveluk K8 with 8 plates leads; if you mainly want the five water types for lighter daily use, the JRIV with only 4 plates delivers them at the lowest price.

3. Ease of Installation

Not every model is equally simple to get up and running:

  • DIY-friendly: K8, SD501DX, JRIV. These are countertop units — place the machine next to your sink, connect the diverter to your faucet, and you're ready to go. Most users can handle the standard installation themselves without hiring a plumber.
  • Professional installation recommended: Super501. Although it sits on the countertop, the Super501 is much larger and heavier than the standard models, with a more involved setup. Someone experienced with plumbing may be comfortable handling the installation, but we recommend hiring a licensed plumber (arranged by the customer) to ensure everything is connected properly.
  • Professional installation STRONGLY recommended: SD501U. The most involved installation in the lineup, the SD501U places the main unit beneath the counter and uses a separate wall-mounted control panel. Installation may require drilling, mounting the control panel, and arranging dedicated plumbing connections. We strongly recommend hiring a licensed plumber (arranged by the customer). If you want an under-counter setup and are prepared for professional installation, the SD501U is worth considering. If you prefer a simpler DIY setup, choose the SD501DX or K8 instead.

4. Budget

  • Under $4,000: JRIV ($3,530)
  • $4,000–$6,000: SD501DX ($5,360), K8 ($5,890), SD501U ($5,890)
  • Above $6,000: Super501 ($7,080)

Financing is available on every model — see our pricing & financing page.

5. Kitchen Setup

  • Countertop space available: any countertop model works (K8/SD501DX/JRIV/Super501).
  • Prefer a clutter-free counter: SD501U installs under the sink (professional installation recommended).
  • Renting your home: countertop models need no permanent installation and move with you — renters should generally avoid the SD501U.

Looking for the SD501 or SD501 Platinum?

If you've been researching the Leveluk SD501 or SD501 Platinum, here's the update: The manufacturer — Enagic — has discontinued both models and replaced them with the Leveluk SD501DX.

The good news — nothing was lost in the transition:

Bottom line: the SD501DX is the same proven 7-plate machine that made the SD501 Enagic's best-seller for over a decade — with an updated design and improved features, including a larger LCD display, a sleeker body, additional language options, and universal voltage input (100–240 V). If the SD501 was on your shortlist, the SD501DX is its direct successor, offering the familiar performance with a more modern design and greater versatility.

Frequently Asked Questions

Do all Kangen machines produce the same types of water?

Yes. Every model in the lineup — K8, SD501DX, SD501U, Super501, and JRIV — produces the same five water types across the same pH range. What varies between models is the strength of the electrolysis (negative ORP) and the machine's capacity, not the variety of water.

Does the number of plates affect the quality of the water?

Yes — plate count affects the strength of the water, not the variety. More plates means more electrolysis surface area, which produces a stronger negative ORP (the water's antioxidant potential): the 8-plate K8 reaches up to −722 mV, the 7-plate SD501DX and SD501U up to −631 mV, and the 4-plate JRIV up to −450 mV. All of them produce the same five water types — but the electrolysis is stronger on models with more plates. Actual readings vary with your source water quality and flow rate.

What happened to the SD501 and SD501 Platinum?

The manufacturer, Enagic, discontinued both models and replaced them with the Leveluk SD501DX — the same 7 platinum-coated titanium plates and the same five water types, in an updated body with 8-language voice guidance. Existing SD501 and SD501 Platinum machines remain fully supported with filters and service.

Can I install a Kangen machine myself?

For most models, yes. The K8, SD501DX, and JRIV are countertop units that connect to a standard faucet — most customers set them up themselves in about an hour or less, no plumber needed. The Super501, while also a countertop unit, is larger and heavier with a more advanced setup, so we recommend hiring a licensed plumber (arranged by the customer). The SD501U is the most involved: as a built-in under-counter unit, it requires drilling, mounting, and dedicated plumbing work, so we likewise recommend a licensed plumber.

Is the K8 worth the extra cost over the SD501DX?

It depends on what you value. The K8 adds an eighth plate — which means the strongest negative ORP in the lineup (up to −722 mV vs. −631 mV) — plus a modern touchscreen. The SD501DX delivers the same five water types at a lower price, with versatile features for everyday household use. Neither is a wrong choice.

Which model is the cheapest?

The Leveluk JRIV, at $3,530 + tax. It produces the same five water types as the larger models, making it the most affordable way into the lineup — a natural fit for singles, couples, and lighter daily use.

Can I upgrade later?

No. Kangen Water machines are purchased as individual models and cannot be upgraded to a higher model later. It is best to choose the model that fits your household size, usage, and preferences from the beginning. If you later decide you want a higher model, you would need to purchase a new machine.

Do all models have the same warranty?

No — the K8, SD501DX, and SD501U carry a 5-year manufacturer's warranty, while the JRIV and Super501 carry a 3-year manufacturer's warranty. All models come with Enagic's official manufacturer warranty when purchased through the authorized purchasing process.
