Well, let's give it a little push.
Bill Gates "beste mann",
Marina Abramović "beste bitch".

Do we belive in the Georgia Guidestones?
Do we know, what is the nature of eugenics?
Do we know who and what the father of BG was?
Do we know what Robert F. Kennedy jr says?

Information and education is a debt to be collected. Not only in the IT-world, that one should think for oneself.

Heres what happened when I used a ionizer I thought to clean the air in an apartment that turned out to have very bad mold, it made it much much worse because negatively charged particles are attracted to positively charged (grounded) objects. So these particles stuck to things that were grounded

Being such a niche product ionizers tend to not be very well optimized. The ones used in LG air conditioners use carbon brushes, will create much more emission at lower voltages than the classical needle array, with negligible ozone at 2-3 kV.

I wonder if there's a place for ion wind driven electrostatic precipitators for air filtering. They could be made dirt cheap. Though there is some conflicting evidence, ionic wind fans seem to be able to be made relatively efficient.

You could make them so cheap you could fill entire ceilings with them at low costs ... this might be enough to bring interior infections down to exterior levels (ie. negligible).
cdev:
My concern is that most of the particles that come into your living space eventually leave the same way they came in, by convection and airflow. However when you have a negative ionizer - the stuff that comes in, stays inside, it ends up sticking to your walls and especially, electronics, or anything thats grounded and pointy, like your hair.
Marco:
The ones in air conditioners and electrostatic precipitators only ionize the air temporarily, they catch the ionized dust to do filtering. The air coming out is neutral.
cdev:
Its different when the air contains toxic risks. I learned about this the hard way and have the scars to prove it. If indeed there is a coronavirus risk, you shouldnt be doing anything to have it cleaned out of the air, at least I wouldnt. I'd leave the ionizer alone. When they do sampling for virus RNA in a room, they go to any fan blades first. Dont use an ionizer unless you have a way of immediately diisinfecting it or something.

In my case there was mold and a very toxic grease in the air. The thin toxic film of dust from hell..
