Hi, Rick--

Here's an article I found helpful in describing ionization and its potential health effects:

They are used for odor removal but also claims are being made that they destroy mold, bacteria, viruses.  Is anyone aware of whether FIFRA registration has been obtained (or is necessary, I would think it would be, if you make claims of killing pests), or if reliable assessments have been performed of these devices, or if the OH ions are indeed safe and effective?  See, for example, http://www.hgiind.com/
