Well here is what the company sent me back - I Googled both processes and they are both bonafide (I found one site that questioned the effectiveness of the Bi-Polar Ionization process but of course they were trying to sell their own product...
How Does It Work? Natural Air Restoration Technology
Air is filled with various contaminants: Dust, Dander, Bacteria, Dry Protein from Feces, Mold, Germs, Viruses and More. It also contains the natural ingredients of the fresh air that Nature intended: Oxygen, Nitrogen, Hydrogen, Water Vapor, etc. CritterZone restores the air we breathe to it’s natural conditions with two distinctly different, but related, continual processes: Bi-Polar Ionization & Plasma Conversion.
Bi-Polar Ionization is a continual process whereby massive streams of positive and negative ions are released into the environment. These ions create charges on the solid matter in the air, which are then attracted to the particles of the opposite charge until
they grow heavy enough to settle out of the air. As the air restores around the CritterZone, the process extends deeper into the environmental space, quickly cleaning a large area from a small source.
The Plasma Conversion Process uses a high-energy plasma flow to convert the moisture in the air into natural cleaning agents. The moisture is converted to additional hydrogen and oxygen components and then proceed to use these to create oxidation and reduction components in the form of hyper-oxides and hydroxides (HOH and OH)– the natural cleaners. These components react to pollutants, virtually destroying odors, mold, bacteria, germs, viruses, dust, dander, etc. These same components combine with the moisture in the air to provide a surface of protection to actually PREVENT germ and mold growth.
