Airocide

It's got a deadly-sounding name, and for airborne nastiness, it's certainly lethal. Airocide ($800) uses NASA-developed photo-catalytic process to destroy Volatile Organic Compounds — harmful gasses emitted by products like paint, cleaning supplies, and even dry-cleaned clothing — that other cleaners miss. It's also FDA approved, and gets rid of all mold, fungi, viruses, and bacteria that enters its cleaning chamber. Of course, none of that means a whole lot if you don't want to put the thing in your house, but luckily it sports a clean design that will blend in with nearly any decor.
