USB-powered ionizer from Thanko

Most computers are pretty clean from the outside, but take a peek behind and inside and you will be greeted with layers of dust that are years old. Dust is bad for any computer, as they can clog up the airflow and cause your PC to overheat in extremely rare cases. This also means the air you breathe isn’t exactly the cleanest around, which leads Thanko to develop USB-powered ionizers. All you need to do is to plug it into any available USB port, and the ionizer will get cracking almost immediately, removing some allergy-causing particles in the process. The Thanko USB Piezo-Ionizer retails for $39 and is available in one color only – white.
