Those Cheap Generic Ionic Air Purifiers

Then there's the ionic air purifiers that have no branding at all. You can generally find them on various websites, as well as brick and mortar bargain stores for about a hundred or so dollars. The fact that they are not branded does not mean they don't work, but you will probably have to depend on the store you bought it from if you want to claim on a warranty. Still, considering the technology that drives ionic air purifiers is fairly simple, the off brands are probably at least mostly safe.
