There is some evidence that ionic air purifiers can be effective at removing some particles and pollutants from the air. However, they are not as effective as other types of air purifiers, and they may not be able to remove all of the pollutants in the air. If you are considering purchasing an ionic air purifier, make sure to research the specific model you are interested in to see how well it works. Also, keep in mind that ionic air purifiers require regular cleaning and maintenance to stay effective.
