Re: Bactericidal Effects of Negative Air Ions on Airborne and Sur...

[Guest guest]

Steve, I doubt it.. But it's a good question.. Let's see if a visit to the USDA library in Beltsville will have the complete report. I'm a few miles away; just might have the time to visit and find the report. I had no idea negative air ionization was thought to be bactericidal. Eliminating dust and small particles yes...

Ken Gibala=============================== Re: Bactericidal Effects of Negative Air Ions on Airborne and Sur...Ken,Is it possible that the ion generator used in this experiment had produced ozone as a by-product? That would also explain the biocidal effects observed.Steve Temes The following has been copied from a USDA website. Those interested in viewing the websites should easily locate it by a google search Can we interpret these tests to indicate a value in generating ion content to control microbial content in environmental air? I'm interpreting the summary to suggest negative ions will rid an atmosphere of much microbial content as well as dust. Does anyone know of other government studies on the subject? Ken
