Jupiter Athena vs. Enagic SD501: Latest Comparison Testing

Published by Alkaline Water Plus

Athena — Best Ionization at all Drinking Levels!

I did a comparison test for the  Enagic SD501 [Kangen Water] ionizer against the Jupiter Athena [which is the water ionizer I use with my family] and am showing the results here. Normally one can expect that as the pH raises, so will the ORP. One way to compare water ionizer quality [in particular with regard to drinking water] is to see which water ionizer has the best ORP at the same pH-level in comparison. This testing shows that the Athena gets a better ORP at all drinking levels of pH, even when the Athena’s pH is a little bit lower than the Enagic.

These are good results for both water ionizers, but significantly better results for the Jupiter Athena.

Here’s the video and chart:
