Kangen® Water

Kangen® Water existing since 2005


Kangen Water® is the registered brand description for activated water of the Japanese traditional company EnagicTM, existing since 2005, which is produced by an ionizer device made by this company.



In Europe, for example, these devices under the description LevelukTM offered by multi level marketing companies are similar to other devices in the assembly and the electrolysis performance. The description Kangen® Water in the operating instructions is only used for activated alkaline water with a pH 8,5, pH 9, pH 9,5 and pH 11.

Filtered and acidic water is not described as Kangen® Water. Kangen® Water is high quality alkaline activated water.

pH 11 water is no drinking water. Therefore “Strong Kangen® Water” (>pH 11) has a warning sign not to drink it. One can remove persistent, greasy stains with it, rinse fish, meat and vegetables with it and use it to clean the floor. There is a special feature to the LevelukTM devices: To create “Strong Acidic Water” (Anolyte) and “Strong Kangen® Water” (Catholyte), these devices are equipped with a liquid tank which has an „Electrolysis Enhancer for producing strong Acidic Water“ made exclusively by the Enagic Osaka Factory, which upon choosing the operating level will mix the correct dosage of water to it.



This liquid electrolysis enhancer differentiates itself from a usual saline solution (NaCl) in water due to the fact that it also contains sodium hypochlorite (NaClO – hypochlorite acid or also „Eau de Labarraque“). Sodium hypochlorite is, for example, the active component of disinfecting and bleaching household cleaning agents and is also promoted as “active chlorine”.

I cannot detect a necessity for this supplement, since mixing common salt to any water ionizer through the supply pipe for salt crystals anyhow creates big amounts of hypochlorite acids in the anode chamber. Hypochlorite acid is the decisive active agent of anolyte, in terms of disinfection power of oxidative water. I presume, that hypochlorite additives in the “Electrolysis Enhancer” are especially used for the saline solution to keep it stable in a germ free condition. The small bottles also have no sell-by date.

Also industrial devices used to create anolyte work with liquid salt (Sole), since it can be dosed more exactly with a so called “Venturi-pump” compared to the addition of salt crystals, which dissolve in varying amounts and varying speeds in water.

As distinguished from industrial devices, which have an exact flow rate control of the feedwater at their disposal, the LevelukTM devices cannot regulate the water flow rate exactly, since a real-time display is missing.

So you have to guestimate with the water tap, since the device can only be connected with the diverter faucet. The problem can be solved with an alternative water connection, which is in exact alignment with the flow rate and therefore guarantees constant results.


In 2016 a similar alternative device for private and professional use was developed by the Korean company „Ionia“, a pioneer of water ionizers.

The AquaVolta ECA tractor. (ECA means electro-chemical-activation).


It hast two water outlets on top, one for normal alkaline activated water, another for functional acidic or alkaline water (pH 2,5 and 11,5) with salt injection before electrolysis.

It is safer to keep them separate to avoid people drinking the strong acidic or strong alkaline water

The AquaVolta® ECA tractor works with separate electrolytic cells: One with seven electrodes for the normal alkaline activated drinking water. The other with 5 electrodes for the tap water with saline injection to generate functional ECA-Water.

The efficiency of this new device in all measurable water parameters (pH, ORP, dissolved hydrogen) in all my tests was much better than any of the Kangen® water devices. Especially the values of dissolved hydrogen differ a lot at a pH of 10 (ionized tap water Munich)

  • Leveluk SD 501 0,7 ppm
  • AquaVolta ECA tractor 2,0 ppm

(both measured with H2 blueTM)


This enormous difference may be due to the new type of 3-layered platinum electrodes (polymer-ion-mesh method).



In a closer look at the surface we can see the obvious advantages of this new spray-type galvanization:



The new electrode type with its larger surface seems to create more ascending hydrogen and smaller hydrogen bubbles that dissolve better in water than the big bubbles from other types of plates.


Also the descaling system of the AquaVolta® ECA tractor works better and the display shows all the necessary information, especially a real-time flow-control, that a modern water ionizer must have. So it ́s time for the Japanese Enagic® Company, to update their old-fashioned and not state-of-the-art Kangen® devices.

Another point for the AquaVolta® ECA tractor is the price. For it is offered by normal distributers and not by a multi- level-marketing system, it is much cheaper, although it is obviously better constructed.

Only the dimensions of 376 x 185 x 435 mm could be a counterpoint. This is due to the two big pre-filter cartridges in the device. The first filter contains activated carbon granules.

The second filter contains a calcium acid and a hollow fiber membrane which is the gold-standard of filtration today.

About Karl Heinz Asenbaum

The Munich-based journalist has been working on the topic of "alkaline activated water" since 2004. For 12 years he worked closely with the alternative physician Dr. Walter Irlacher, with whom he wrote two successful books: "Service Manual for Humans” (Service Handbuch Mensch) (2006) and "Drink Yourself Alkaline” (Trink Dich basisch) (2008,2011). Since 2014 he has been contributing his knowledge and experience to Aquacentrum and giving lectures worldwide. “Electro-activated Water", the world's most comprehensive book on the subject, was published in 2016. View all faqs by Karl Heinz Asenbaum
