The most powerful alkaline water ionizer — peak performance

K8 is Enagic's flagship ionizer — chosen by those who refuse to wonder whether their water is good enough. It simply is the best.

8 electrodes — record ORP

Eight massive platinum-coated titanium plates generate ORP reaching -722 mV. This is measurably the strongest drinkable antioxidant available in a home device. For comparison — cheap competitors achieve -200 mV.

Up to −722 mV ORP

Medical certificate from Japan

K8 holds the Class II medical device certificate from Japan's Ministry of Health (MHLW). Not a "supplement," not a "wellness gadget" — a device medically classified by the Japanese government. View certificates →

Medical Class II
🔬
Five water types from one device

pH 2.5 to 11.5 — from strongly acidic (disinfection, skin care) through neutral (medications, infants) to strongly alkaline (Kangen drinking, pesticide removal). One device replaces dozens of household products.

5 water types
🏗
25+ year lifespan

Enagic services ionizers built 25 years ago — that's not marketing, that's fact. Massive platinum-coated titanium electrodes don't wear out like thin galvanic layers used by competitors. Buy once, use for decades.

Global service in 23 countries

Enagic has physical service centers on 5 continents. Whether you're in Europe, Japan or the USA — your K8 will be serviced. No cheap internet brand can guarantee that.

Zero plastic, zero waste

The average family of 4 uses 1,500–2,000 plastic bottles a year. K8 eliminates that cost completely — both environmentally and financially. Water straight from the tap, better than purchased.

Alkaline ORP water — what does scientific research say?

"Electrolyzed water exhibits strong antioxidant properties due to the presence of active molecular hydrogen."

Since 2007, more than 1,200 peer-reviewed scientific studies have confirmed the properties of molecular hydrogen (H₂) — the gas present in K8 water during electrolysis. Studies indicate potential in reducing oxidative stress, supporting recovery and cellular protection.

K8 produces water with a negative ORP — meaning water that can "donate" electrons to free radicals and neutralize them. This is the opposite of most beverages (coffee: +300 mV, cola: +400 mV), which need your electrons to function.

K8 is the choice of the health-conscious

K8 is not for everyone — it's for those for whom health and quality are not temporary.

🏃
Athletes and active people

Fastest muscle recovery, optimal hydration before and after training, natural support without supplements. K8 is the professional's choice.

👪
Families of 4+ people

8 electrodes and higher capacity mean K8 serves a large family without loss of quality. Water for everyone — children, adults, seniors.

🧬
Health-conscious individuals

Struggling with chronic fatigue, looking for natural antioxidants, interested in oxidative stress? K8 provides maximum scientific parameters.

pH 11.5 users

Strongly alkaline water pH 11.5 emulsifies fats and removes pesticides from vegetables and fruit. Only K8 in the lineup reaches this level without issues.

Questions that hold you back

I know these doubts. I'll answer them honestly — no sugarcoating.

The price is very high. Is it really worth that much?
I understand. But let's do the math: a family of 4 buys about 400 water bottles a year — that's about 300–500 EUR. After 5 years that's 1,500–2,500 EUR thrown away on plastic. K8 pays for itself within a few years and serves 25+. The real question is: can you afford to keep buying bottled water?
How do I know Kangen water really works? It sounds like marketing.
Healthy skepticism is valuable. That's why I recommend research — not my words. Over 1,200 peer-reviewed publications on the properties of H₂ are available on PubMed. The Class II medical certificate from Japan is issued by a government institution, not a marketing company. I can also show you how to verify ORP with a home meter.
My tap water quality is poor. Can the ionizer handle it?
Good news: the Kangen ionizer first filters water through the FC1 filter, then ionizes it. For harder water or poorer quality supply, I can help select an additional Ultra-E pre-filter that solves the problem. I've tested K8 in various regions — it always performs well.

Leveluk K8 reviews — what do they say after a year of use?

Athlete
★★★★★

"I run marathons. After switching to K8, my recovery time was cut in half — with no changes to my diet. I measured ORP with my own meter: -780 mV. My coach now has one too."

Family of 5
★★★★★

"Fifth child on the way so we were stressed financially — but K8 was worth it. 450 EUR less per year on bottled water. The kids only drink Kangen now. The difference in hydration is visible to the naked eye."

"I recommend K8 to patients with IBS and hydration issues. Results in my clients — subjective improvement in well-being already in weeks 2–3. I recommend it wholeheartedly."

Most common questions before buying K8

What differentiates K8 from SD501DX — is the upgrade worth it?
K8 has 8 electrodes (vs 7 in SD501DX), resulting in higher ORP (-722 mV vs -600 mV) and greater capacity at the same quality. SD501DX is excellent for a typical family of 4. I recommend K8 when: (1) you have 4+ people and use water intensively, (2) you need maximum ORP for health purposes, (3) you use pH 11.5 water for cooking and cleaning. Call me if unsure — we'll discuss your situation.
How long does installation take and do I need a plumber?
Installation takes 10–15 minutes and requires no plumber or drilling. The device connects to your existing kitchen tap using the included diverter. Instructions are included and I offer phone and video support — call me during installation if you have any questions.
When does the filter need replacing and what does it cost?
The FC1 filter needs replacing after approx. 6,000 liters (K8 notifies you by voice and on display). For a family of 4 that's roughly once a year. The original Enagic filter costs approx. 120–140 EUR. That's less than a few months of bottled water for the same family size.
Is K8 suitable for hard water?
Yes. K8 handles harder water thanks to its automatic electrolysis cleaning system after each use. In areas with very hard water (>300 mg/L CaCO₃) I recommend the Ultra-E pre-filter, which additionally softens water and extends electrode life. I can check your water parameters before purchase — just write or call.
What is the Leveluk K8 price and is financing available?
The Kangen K8 price is 4,600 EUR net (5,520 EUR incl. 20% VAT). Companies pay the net price. Yes, I offer instalment payment options — contact me and we'll discuss financing tailored to your budget. The Enagic K8 is an investment that pays back financially over 5–10 years through savings on bottled water.

Leveluk K8 vs SD501DX — which ionizer to choose?

All Kangen Enagic water ionizers produce excellent alkaline water. Compare Leveluk K8 vs SD501DX and JR IV — the difference lies in electrode power and intended use.
