You just want to avoid an arc (spark) in the air (usually visible and also
audible), and then you should only be getting the ions.
With Van de Graaff generators I think you can go well above 50KV without
arcing, as long as there is no ground potential nearby. Part of this has
to
do with the large surface area.

Get a lump of one of the items they mention here:

That'll give you free electrons, such that you won't need corona-grade
voltages to encourage the ions to go out into the room. ;-)
Cheers!

Ozone is not an ion; it is triatomic oxygen, a neutral molecule.

Neutral in atomic charge, you mean.
