As I said in a reply to a similar query a year or so ago:
There had been a lab devoted to exploration of positive ion/negative
ion ideas at Rockefeller University. I visited it and discussed the
subject with its principal investigator close to 20 years ago, also
took home a large packet of relevant materials. (He is no longer
there, left within a year or so I believe, and so far as I know this is
no longer an area of interest there). I have also read a rather
damning critique by a German biometeorologist expert on electrical
atmospheric phenomena.
My conclusion from all this (and a few more things) is that what seemed
initially like an interesting idea never reallyh panned out. I am
skeptical about claims for benefits of negative ion generators.
