Again, it looks like Henig STILL believes that something real was happening in his unit; he has newer patents along that line.
Then if this really IS the case it means that the only sanitatin takes place INSIDE the unit, whch makes it no better as a sanitizers than an ozonator or UV sanitizer. The only water that is being sanitized is inside the chamber! Once again this means that a fast acting residual sanitizer at levels that are effective needs to be present in the water.

It IS all very interesting!
