During crop-burning season in India, when the air is hazardous, would an ionizer + ozone be a net positive?

Interesting, we banned it in the early 90s in the UK (I used to love watching it).

It's not a simply equation though, eg https://www.researchgate.net/publication/230319729_The_effec....

No: ozone only makes things worse. Plus, a lot of smoke from burning plants has large particles that can be filtered much better with hepa filters
