would like to build an ionizer /filter for my home ....i am seasoned in

better and on a larger usable scale preferably.. thanks for any info

I have built different purifiers. Ionizers basically emit an ion wind. If
you do it right there is no high level of ozone. You can also have an
oppositely
charged plate to help collect them. I have seen many dirty walls caused by
ionizers as the particles stick to nearby objects. They are in many air
filters
or part of them. For my first HV plate type, I went to Sears and studied
there system. I just copied it. Later I bought a small tabletop
model from Sears. Same as that one on TV. An electrified dust particle
will be attracted to a opposite charged plate. The plates are spaced + -
+ - + etc.
An emitter is placed in front of the plates to charge incomming particles.
There are tons of these filters installed everywhere, including all bars
for
smoking. Its fun and sometimes economicle to built your own, but
it sure is easier to just buy them. I don't see as many HV transformers on
the maket,
especially from Herbach & Rademan, but the use of small switching
transformers
would be the way to go now days. Ozone machines can also be very nice.
while people are vacant, Ozone cleans up the bad smells from bars and
restuarants at night,
allthough some use them while people are there, not a good thing.
I also bought an ozone machine for personal use. Yes, I have built Ozone
machines.
Running HV 60 Hz AC to closly spaced electrodes will produce Ozone. There
is another
machine which many electronics assemblers are familiar. When you emit both
pos and neg ions, this will reduce electrostatic discharge problems around
electronics. There is no effective cleaning action. Its also used in some
small nozzle
air guns.
