All very interesting.

The change from the original Fountainhead patents to the current incarnation is interesting. It appears that the old product focused on what happened inside the cartridge while the new ones are merely passive "mineral-izers".

Again, it looks like Henig STILL believes that something real was happening in his unit; he has newer patents along that line. But Zodiac and Denkewicz seem to have given that up. There was some justification for the "'active oxygen" and catalyst language dealers have used, in that Henig and other Fountainhead folks seem to have believed it. (Who knows: it might even be true!) But, it doesn't apply to the current Nature2, at all.

Seems to be an example of a corporation seeing value, not in the actual product, but only in the brand name.
