Ionic Tease: Homemade Smog Machines

I used to use air purifiers with ionizers all the time. I loved them. The idea was that the ions would stick to any dirt in the air and drag it down so you wouldn't breathe it in. Now they come out with this study that shows that's sort of like making your own smog in your home. It's toxic. I'll bet Ionic Breeze isn't happy about that study.
