Water Ionizer Face-Off #4: Enagic SD501 $3800. Water vs. Jupiter Athena Water Ionizers

Published by Alkaline Water Plus

Today I had the pleasure to test two great water ionizers, the Enagic $3800 Water ionizer [the SD 501] and the Jupiter Athena water ionizer.

The results were close, but the Athena was a bit better in levels 2 and 3 [which I feel are the most important levels, because they are the levels that most people drink at].

The Athena has a better design than the Enagic — more sophisticated and efficiently designed. Jupiter Athena is Jupiter’s highest-end water ionizer. It is a tried-and-true water ionizer design, that has been around for many years. It has come out top in many water ionizer comparison tests, including the ones done by Silver State Labs [an independent certified lab]. The filtration in the Athena is exceptional along with the internal self-cleaning system, called the DARC [double automatic reverse cleaning] cleaning system. The Athena also has a better warranty than the Enagic’s 5-Year Warranty.

Here are the videos, chart, and commentaries for today’s water ionizer comparisons:

10/29/ Enagic/Athena-1 Enagic Athena
Level 1  pH/ORP

10.5/-780  Better


Level 2   pH/ORP/rH

11 /-805 / 1.83

10.4 /-710 / 3.8 Better because the water’s more drinkable

Level  3   pH/ORP/rH

11.3 / -825 / 1.77

11.1 / -817 / 1.63 [Tiny bit better]

Level 4   pH

11.4  Better [for emulsifying oils]


Acid   pH


2.5  Better [for killing germs faster]

Here are my comments about today’s water ionizer comparisons:

  • Enagic’s results at level 1 were higher, but the pH was too high for most people starting in at drinking ionized water.
  • The Athena’s ORP at level 2 was almost as good as the Enagic’s but with a far more drinkable pH. Same for level 3.
  • The Enagic had a slightly higher pH at the highest level [this was without the aid of any chemical], but both water ionizes’ high alkaline results were plenty high enough to emulsify oils.
  • The Athena had a slightly better low acidic pH [without the aid of chemicals], but both water ionizers’ low acid pH results were plenty low enough to kill germs.

The very best thing I have ever purchased is a WATER IONIZER, and I've been in perfect health ever since I started drinking ionized water 25 years ago! Understanding and knowing how to control and manage my own body's pH and antioxidant levels at the cellular level has made all the difference in the world in my life, my family's lives and in a countless number of my friends and associates over the years.
