Alkaline water has a pH of above 7. It can be naturally alkaline for example, spring water can contain minerals that make it more alkaline, with baking soda (sodium bicarbonate) added to it or it can be ionized to make it that way.

In an Alkaline Ionizer, water goes through a process of electrolysis, the cations and anions are separated into acidic and alkaline streams. The alkaline water siphoned off the cathode side that carries the negative electric charge, contains increased levels of OH− ions and has a higher pH, also known as Electrolyzed Reduced Water (ERW) or Alkaline Electrolyzed Water (AEW).
Make informed decisions if you wish to consume alkaline water, what is the recommended pH range and the effects it has on health:
WHO Guidelines for pH in Drinking Water
Exposure of pH 10–12.5 have been reported to cause hair fibres to swell. In sensitive individuals, gastrointestinal irritation may also occur. The optimum pH will vary in different water supplies according to the composition of the water and the nature of the construction materials used in the distribution system, but is often in the range 6.5–9.5.
Studies on Alkaline/ Electrolyzed Water Effects on Health
- Promotion of alkaline diet and alkaline water to the public for cancer prevention or treatment is not justified. There is no actual research to either support or disprove it. (bmj.com).
- In the Study on nih.gov: Effects of long-term exposure to alkaline drinking water in rats – Animals exposed to alkaline water (drinking water supplemented with Ca(OH)2 or NaOH) with pH 11.2 and 12 for a year had up to 29% lower body weights, dull and patchy fur.
- A study on (nih.gov): Alkaline Water and Longevity – Rats that drank alkaline ionized water (pH 8.5 and 9.5) had signs of greater longevity.
- The findings of a study on (nih.gov): Daily ingestion of AEW influences human health indicate that ingesting AEW (alkaline electrolyzed water pH 9.2 ± 0.2) on a daily basis improves health and exercise capacity as well as improvement in gastrointestinal symptoms.
- The study on the Effect of ERW pH 9.47 on Cell Culture Redox (Reduction-Oxidation) Cellular State – The H2 dissolved in ERW acts as an antioxidant, neutralizing the free radical. This is very important if we consider that oxidative stress contributes to the development of many inflammatory diseases (nih.gov).
pH Levels in Municipal Drinking Water
- pH levels in drinking water in Malaysia is between 5.81 to 7.41 (Institute for Medical Research & National Institutes of Health, Malaysia)
- In Hong Kong, hydrated lime is added to water leaving the treatment works to regulate the pH value of the water to 8.2 to 8.8 (gov.hk).
- In the US, tap water pH varies; typically about 7.5. EPA recommends that municipal drinking water is kept at a pH of 6.5 to 8.5 (healthline.com)

- The Water Quality Association (for Enagic) Gold Seal: NSF/ANSI 42 Aesthetic Chlorine, Taste and Odor Reduction
lowyat forum: MLM product, over-priced. The science has not been proven yet. Promotion that Kangen water can cure various illness such as cancer can mislead people and result in offenders being charged. If you want high PH water just buy panasonic brand which has the same function, at much lower price.

Panasonic Alkaline Ionizer TK-AS45
First, residual chlorine and impurities are removed to create purified water. Then, the purified water is electrolyzed by a high-power electrolyzer featuring 3 electrodes to create alkaline ionized water and acidic ionized water – four different pH values. The baked platinum-coated titanium electrodes are durable and exceptionally resistant to deterioration.
The filters are made of four kinds of materials with different sized holes that eliminate harmful substances and 99.999% of bacteria – (1) Non-woven fabric (2) Ceramic (3) Activated carbon (4) Hollow fiber membrane.
