Is it true that ionic air purifiers remove airborne particles from indoor air effectively?
Partly. The EPA states ion generators may remove small particles but are relatively ineffective on large ones, and one 2021 study recommends HEPA mechanical filters over ion-releasing purifiers. A reference article describes ionisers removing particles and cites a 2018 review calling negative air ions highly effective, so the evidence only partially covers the claim and points both ways.
