Plasmacluster Ion Technology

Sharp Corporation has demonstrated that Plasmacluster Ions, a technology behind its Plasmacluster™ Air Purifier line-up, "reduces activity of the highly fatal and highly pathogenic airborne H5N1 avian influenza ("bird flu") virus by 99%."
If you consider going for Plasmacluster Ions technology solely based on your fear of avian flu, then think again. The remaining one percent of viral particles can still kill you. What we are interested in here is the technology itself:
A built-in Plasmacluster Ion generator produces positive and negative ions from the water molecules (H2O) and oxygen molecules (O2) in the air. These ions, which have strong germ-killing qualities, are released back into the air.
By themselves, these positive and negative Plasmacluster Ions are inherently unstable, but they become stable when they cling to "something." When they encounter airborne germs (like mold spore) or toxic substances (like tobacco smoke), they form clusters surrounding the offending entity.
By surrounding airborne microbes (for example, mold fungus) the ion clusters destroy them, and also quickly eliminate and decompose the sources of annoying odors...
The Plasmacluster Ions form into groups of positive and negative ions. They knock out airborne mold fungus and decompose sources of annoying odors. Experiments conducted by a testing organization recognized by Japan's Ministry of Health, Labor and Welfare demonstrated that this technology has the power to reduce mold fungus by 90% in one hour. Air purification technology based on Plasmacluster Ions represents a revolutionary new system for cleaning the air totally unlike any existing techniques.
