Bottled hydrogen water loses most of its hydrogen long before you drink it. The gas naturally escapes through plastic and over time. “Alkaline” waters in stores are usually just minerals added to raise pH level, not naturally ionised, and does’t contain meaningful hydrogen at all.

The K8 Water Ioniser creates the water fresh, on demand, using electrolysis, so you’re drinking it while the hydrogen is still active. That’s why people feel the difference so quickly: it’s not about pH hype or the additives, it’s the presence of dissolved hydrogen right when you drink it.

1. It’s extremely small
Hydrogen (H₂) is the smallest molecule in existence. Because of it's size, it spreads quickly through the body and can reach areas larger antioxidants can’t, including inside cells.

2. It supports balance
Hydrogen is selective. Meaning it mainly interacts with excess oxidative stress, this is the “wear-and-tear” created by processed food, alcohol, pollution, and everyday life.

3. People often feel a difference after drinking this water.

· Feels lighter on the stomach

· Less bloating

· Smoother digestion

· Clearer skin

· Easier to drink more water without trying

No. Supplements, mineral drops, or dissolvable tablets work by adding minerals to the water. The K8 works completely differently, it uses electrolysis to dissolve molecular hydrogen (H₂) into the water. That’s what creates the smoother texture, easier hydration, and light-on-the-stomach feel people notice. Tablets and drops can’t generate hydrogen, so the experience isn’t the same.

Regular filters only clean water. The K8 uses medical-grade platinum-coated titanium plates and an advanced electrolysis chamber to create hydrogen-rich, antioxidant water, something filters simply can’t produce. It’s engineered to last 20+ years, replaces bottled water and multiple household cleaning products, and its build quality is closer to a medical device than a countertop filter. The upfront price is higher, but the long-term value ends up far greater than the cost for most people.

These units routinely last 15–25+ years because they’re built in Japan by the original manufacturer, not a third-party factory. Everything from sourcing the materials to hand-assembling and testing each unit in their Japan facility. The electrolysis chamber uses medical-grade platinum-coated titanium plates and a self-cleaning system, which is why units from the early 2000s are still running today. With little maintenance, most people only replace the pre-filter, not the machine.

Very little. The system is mostly self-maintaining.

Automatic self-cleaning:
After heavy use, the K8 runs a quick refresh cycle that clears minerals from the plates so every glass delivers the same clean, hydrogen-rich water, with zero effort from you.

Simple monthly rinse (E-Cleaning):
Once a month, you insert a small citric-cleaning cartridge. It runs on its own while you go about your day.

Filter replacement:
The internal filter typically lasts 12 months depending on water quality and usage. Swapping it is quick and doesn’t require tools.

Occasional deep service (optional):
Every few years, some owners choose a professional deep-clean to remove long-term mineral buildup, similar to servicing a high-end appliance. Most people don’t need it regularly.

The machine handles the hard work; you only manage light preventive care.

People say the taste feels “different” in the beginning but usually because they are used to chlorinated or mineral-heavy water tap water. After a few days, most people describe it as crisp, clear, and incredibly smooth.

For the first week or two, begin with the 8.5 setting. It gives your body and your taste buds a gentle transition from chlorinated or mineral-heavy tap water to clean, hydrogen-rich water. After that continue with 9.5 and drink just like you would as normal water whenever you’re thirsty.

Yes kids and pets can drink it. Hydrogen-rich water is simply cleaner, filtered water with dissolved molecular hydrogen. For the first week or two, begin with the 8.5 setting. It gives their bodies and their taste buds a gentle transition from chlorinated or mineral-heavy tap water to clean, hydrogen-rich water. For babies use Neutral Water (7.0) when making baby formula.

Yes. You can use the 9.0 setting to cook with. Most people use it for soups, rice, pasta, coffee and tea because it tastes cleaner and brings out the flavours better.

Yes, you can store it. Just know this:
Hydrogen is a gas, so it slowly escapes over time. Chilling or refrigerating the water keeps the hydrogen in longer. Heating or boiling it makes the hydrogen leave faster, but the water is still clean and great for cooking or drinking.
For the best effect, drink it fresh from the machine when you can, or keep it chilled in a airtight vacuum glass or stainless-steel container.

Use the neutral 7.0 setting when taking medication. Medicines are formulated and tested with neutral water, so using the 7.0 option keeps things consistent with how they were designed to be absorbed.

Dissolved hydrogen begins diffusing out immediately. In an open glass, it starts to escape within minutes which is why drinking it fresh gives you the highest benefit. A sealed stainless-steel or glass bottle can slow the loss to a few hours, but it can’t ‘hold’ hydrogen long-term. It’s also why you don’t see true hydrogen-rich water on supermarket shelves, hydrogen is naturally short-lived, like any fresh nutrient it's most potent when it’s just made.

Drinking Water (8.5 → 9.5)

Hydrogen-rich water for everyday drinking. Most people start at 8.5 and move up to 9.5 once their body adjusts.

Simple use: daily hydration, coffee, tea, cooking.

Neutral Water (7.0)

Clean, filtered water. This is the one you use for taking medication or for baby formula.

Beauty Water (6.0)

A slightly acidic water used externally on the skin. People like it as a natural face & toner or hair conditioner.

Strong Cleaning Water (11.5)

A high pH water used for degreasing and removing tough residues from produce or surfaces. It helps lift oils and pesticides from fruits and vegetables.

Strong Disinfecting Water (2.5)

A very low pH water used for sanitation and cleaning surfaces. It’s a natural disinfecting water for things like cutting boards, utensils, and household areas.

The white flakes you’re seeing are usually tiny mineral crystals, such as calcium or magnesium. They naturally appear when high-pH water is produced, especially in areas with harder tap water. A few particles are completely normal and safe. If you begin to see a heavier buildup, it may be a sign that your K8 needs an simple E-Clean or filter check.

A brief cloudiness right after dispensing is completely normal. It’s caused by the high concentration of dissolved hydrogen forming tiny micro-bubbles as the water settles. These bubbles rise and disappear within a couple minutes, and the water becomes clear again.

This is actually a good sign, it indicates the machine is producing fresh, hydrogen-rich water as designed.

Yes, you can store it. Just remember that hydrogen is a gas, so it gradually escapes over time. If you want the hydrogen benefits to last longer, keep the water in an airtight glass or stainless-steel bottle and store it chilled.

Heating the water (boiling, cooking, leaving it in the sun) makes the hydrogen dissipate faster, but the water itself is still clean and perfectly fine to drink or use. For the best results, enjoy it fresh whenever you can.

Yes, you can mix protein powder or nutritional supplement with the 9.5 setting. Many people have reported that the water is smoother, mixes easily, and it feels lighter on the stomach. Hydration also plays a big role in how nutrients move through the body, so using clean, hydrogen-rich water can support overall nutrient delivery. For prescription medications use the neutral 7.0 setting.
