We have an interesting gadget from Japanese site Thanko: a USB air ioniser (blimey, we really are running out of things that we can USB aren’t we?). If you’re worried that the air around you isn’t saturated with enough ions, then the EPI585 USB Piezo Ioniser wil do the trick for you. Just think: with a laptop you can improve the air quality around you on the go. Ahh, the power. The set also comes with a power adaptor for the cigarette lighter in your car. Unfortunately the site’s in Japanese, but nonetheless, feast your eyes.
