I'm curious whether anyone has dissected any of the latest version of
personal air purifiers? They are also sold as usb port plug ins to
purify the air near your computer...and, still others are sold to
purify the air in your car. They are sometimes called negative ion
generators and the sellers claim that breathing the ozone they produce
is supposed to improve your health:: They usually include 'piezo' in
the title of the product.

"Piezo" comes from the method used to produce high voltage, which
produces the ozone (or negative ions as the sellers like to put it).
Piezo technology means piezotransformer or piezoelectric transformer
or piezo transformer, they go by a few different names. I'm fascinated
by these devices and want to learn more, especially regarding the
drivers.

I was wondering whether anyone had taken any of these units apart or
whether there are any websites dedicated to sharing information about
these new technology high voltage generators?
