First, two numbers that matter

Every one of the five waters is described by two simple measurements. Understand these and the whole range makes sense.

pH — how acidic or alkaline

pH runs from 0 to 14. Below 7 is acidic, 7 is neutral, above 7 is alkaline. It is a logarithmic scale, so each whole step is a tenfold change. Your ioniser lets you dial the water from strongly acidic (~2.5) all the way to strongly alkaline (~11.0).

ORP — oxidation-reduction potential

ORP, measured in millivolts, describes whether water tends to give away electrons (a negative, "reducing" value) or take them (a positive, "oxidising" value). Freshly ionised Kangen water carries a negative ORP; the acidic waters carry a positive one.

Freshness — why it's made on demand

Dissolved molecular hydrogen and ORP both fade once water meets the air, which is exactly why a Kangen machine makes each water at the tap, the moment you need it — never bottled, never left to stand.

Strong Kangen Water

Needs Electrolysis Enhancer

A high-alkaline water made with the electrolysis enhancer. Not for drinking — it's a powerful, natural helper around the kitchen and for tough cleaning jobs.

ORPStrongly negative

Good to know Let vegetables sit in it for a few minutes, then rinse with Clean water.

8.5–9.5 pH
Drinkable

Kangen Water®

The signature hydrogen-rich alkaline drinking water, selectable across three levels (8.5, 9.0 and 9.5). This is the water you drink and cook with every day.

ORPNegative
How it's madeStandard electrolysis of filtered tap water — no enhancer.
Best used for
  • Drinking
  • Cooking & soups
  • Coffee & tea
  • Rice & grains
  • Watering plants

Good to know Start at 8.5 and work up as your palate adjusts; brilliant for coffee and tea.

7.0 pH
Drinkable

Clean / Neutral Water

Purified, pH-neutral water straight from the filter, without electrolysis — gentle and neutral for the most sensitive uses.

ORP≈ Neutral
How it's madeFiltration only — the plates are bypassed, so no pH change.
Best used for
  • Taking medication
  • Baby formula
  • Neutral cooking
  • Refilling appliances

Good to know The right choice whenever a recipe or a medicine needs plain, neutral water.

4.0–6.0 pH
Not for drinking

Beauty Water

A mildly acidic water (around pH 4.0–6.0) prized as a natural astringent. Not for drinking — it's for skin, hair and around the home.

ORPPositive
How it's madeMild electrolysis on the acidic side — no enhancer needed.
Best used for
  • Facial toner
  • Hair rinse
  • Pet coats
  • Polishing glass & mirrors
  • Watering delicate plants

Good to know Decant into a spray bottle for an easy daily facial toner.

2.5 pH
Not for drinking

Strong Acidic Water

Needs Electrolysis Enhancer

A low-pH water (around 2.5) made with the enhancer, valued for cleaning and hygiene around the kitchen. Not for drinking.

ORPStrongly positive
How it's madeStrong electrolysis with the Electrolysis Enhancer added.
Best used for
  • Sanitising surfaces
  • Cutting boards
  • Kitchen & bathroom hygiene
  • Wiping door handles

Good to know Spray onto a surface, leave briefly, then wipe — great for boards after raw meat.

Strong Kangen and Strong Acidic waters are produced with the Electrolysis Enhancer — a food-grade saline solution added to a small dedicated tank. They are cleaning and food-prep waters, never for drinking.

The five waters at a glance

One tap, five jobs. Only the two drinking waters should ever be consumed.

Only Kangen (8.5–9.5) and Clean (7.0) waters are for drinking. Strong Kangen and Strong Acidic waters are made with the Electrolysis Enhancer and are intended for cleaning and food preparation — not for consumption. pH and ORP figures are Enagic's own reference values and vary with your source water.
