Cleaner air, via USB port

If you sit at a computer all day, you might acquire a certain… how should we put this… fragrance. We don't mean to be rude, but it's better you hear it from us than someone else. Perhaps you could use this USB mini-ionizer/air purifier. Powered by your computer, it can sit on your desk and take care of about a 9-foot cube of space, eliminating odors and "tiny particles," which we assume are bad. At $20, it's a small price to pay for making your desk smell great. A shower might be cheaper, but you can't power it with your USB drive. Yet.
