I read plasma technology can possibly break down bad things better then
conventional technology. I have subsequentially seen a few major brands
touting plasma technology in their air cleaners yet the rate of cleaning a
room don't seem so much better and they don't seem to be advertising that
much if it worked better but on the box it looks interesting ( PLASMA
TECHNOLOGY). Filtrete has recently come out with a aircleaner and no mention
of plasma though. I think Sears has a few models with plasma. Has anyone
bought one and compared to conventional hepa filter technology? I am not
including the ionizers although I never got one with positive charging
ionizers. The negative ones I got were a complete waste of money , unless
you like the smell of electrically charged air that was just as dirty as
before :(  no thanks!. The people who sell the negative ionizers should be
sued in court if you ask me. Opinions needed. I need a great air cleaner and
so many out there.
 Finally I read not enough experimentation and useage history is known from
plasma to know whether the technology is completely safe for air cleaners.
Comments welcome.
