Air purifier for your computer

Is the air around you tainted? Don't you wish you could just plug something into your computer that probably doesn't help it at all? Yea, me too. It seems that the world is becoming overpopulated with useless USB devices. The Ionic USB Air Purifier is one that I think we can add to the list.

The little gadget "discharges negative ions to absorb second-hand smoke, odors, clean airborne dust, and eliminate bacteria, germs, viruses." Even though it has nothing to show for all of its hard work, like a fan or filter, I'm sure it works. Really, I am.
