Hi Russ,

Actually, as I understand, this machine works differently then the one you
describe.

It contains a glass plate with a wire mesh screen on it.  It receives
electrical contact from the machine and produces trace amounts of ozone.
(.04 ppm, well under EPA Standards)  This mimics a thunderstorm in outside
air (without the thunder clap)  *grin*   The ozone then oxidizes the
particulate matter in the air.  (bout as much as I know about it)
