It is rare that you will ever see the Enagic water ionizer in a comparison water ionizer test. Most Enagic dealers are reluctant to even want to see comparison testing. So I feel priveledged to bring these videos to you.

We tested and compared the Enagic SD 501, the Melody, and the Athena water ionizers!

Throughout this testing there was an overall trend toward the… Enagic not having the best quality of drinking water.  See below for a good explanation of how the best quality of drinking water  for water ionizers is determined.

Comparing the Enagic, Athena, Melody, Tyent & KYK Water Ionizers

Level 3 – Drinking Water

Enagic, Athena & Melody @ Level 3 or Kangen Water 9.5

Level 3 – Drinking Water [Cathie’s Analysis]: In the above video and chart for Ionized Water at Level 3 it can be seen that the winner for healthiest [rH] drinking water [ionized water at Level 3 is the Athena.  [The lowest number for rH being the best.] See more below about rH.

Level  4 – The Extremes

Enagic, Athena & Melody Level 4 or Strongest Level

Level 4: You can see in the above video and charts that the Enagic for these tests is getting the  “Low Acid”  in both videos and the Enagic gets the “High Alkaline” in the 2^nd video [with the Tyent beating the Enagic in Highest Alkaline in the 1^st video]

Level 2 – Drinking Water

Athena & Melody Level 2 or Kangen Water 9.0

Level 2: The Athena is the winner of the best relative Hydrogen for level 2 [the lowest number being the best].

Level 1 – Intro-Level Water

Enagic, Athena & Melody Level 1 or Kangen Water 8.5

Level 1: The Athena is the winner of the best relative Hydrogen for level 2 [the lowest number being the best].

Note: These water ionizer comparison tests were conducted in St. Peters, MO, which has a tap water which is 8.46 pH and +195 ORP

*The rH of a solution is based on a formula applied to the pH and ORP to arrive at the relation between the level of ORP to the level of pH. It is the best measure of the healthiness of that ionized water. I always consider the rH to be the most important measure to look at in any water ionizer comparison test.

• rH = (ORP / 30) + (2 * pH)
• Here’s an example: if you have two water ionizers producing water at a pH of 9.5, and one has an ORP of -300 and the other has an ORP of -400, then the one with -400 is producing water at a healthier overall quality. Most people testing water ionizers don’t get the exact same pH readings for all the water ionizers tested. So the rH formula is necessary to really see which water ionizer is producing the healthier water. The formula is a very simple one, and anyone comparing water ionizers should look at the rH of the water at the drinking water levels if they are trying to figure out which water ionizer is best. Because ORP is a very tricky measure to get and ORP meters can vary from test to test [depending on how well or frequently they’re cleaned, source water and other factors] it’s important to only compare the ORP or rH of water ionizers tested in one setting by the same tester. RH is measured on a scale of 0 to 42, with 0 being the healthiest and 42 the unhealthiest. Tap water in St. Louis is usually around 30 – 35 rH. Any water under 28 rH is considered “reducing” and so is healthy for you.
• “The relative hydrogen scale was first proposed by Clark in 1923 to the scientific community (mostly inorganic chemists) as a means of measuring the true reducing power of hydrogen present in an aqueous solution…”* Go to this website to see this article and get a more thorough and scientific explanation of rH: http://h-minus-ion.vpinf.com/rH-score-1.html
