Make Your Air Doubleplus Pure
It is conventional wisdom among people who weren't suckered into buying ionic air purifiers that the majority of them do nothing. Conventional wisdom was wrong. In fact, ionic air purifiers emit high levels of ozone - better known as smog. Perfect for those that want to bring the great outdoors home, if by "great outdoors" they mean "midtown Manhattan at rush hour."
So when someone finally invents an air filter that actually doesn't do anything, it can honestly claim that they are "new and Improved."

From the linked article:
"Correction: This article in its original form was inaccurate. The study involved two types of air purifiers, those commonly called ionic and those that employ a process called ozonolysis. Only those using ozonolysis were found to contribute to ozone levels that can in some cases exceed air quality standards. “Ionic air purifiers do emit ozone,” said lead researcher Sergey Nizkorodov, a chemistry professor the University of California, Irvine. But he added that “none of the ionic air purifiers produce enough ozone when they are used properly to exceed smog alerts.” The confusion was generated in part by a UC Irvine press release that did not clearly distinguish between these two types of machines. LiveScience regrets the error and any confusion it may have caused. The article has been revised."

Boo, Nina! Facts and corrections are a buzzkill.
On a more serious note, after reading that correction I still don't know which brands are safe and which are not - or what "improper" uses would be dangerous.
