The Mini USB Port Piezo-Ionizer is designed to keep you cool and calm via a steady flow of ‘high density negative ion output.’  We’re talking 2 million negative ions per cubic metre here, so it’s bound to be really Fresh Prince of Bel Air round your desk with this puppy. Actually that’s rubbish isn’t it? We have absolutely no idea whether that’s a good number or bad. It’s just got such a lovely lot of zeros to play with. Ho hum. $16.00.

 Mini USB Port Piezo-Ionizer uses proprietary piezoelectric technology to generate a high-density negative ion output. Its micro-thin design can be plugged directly into your computer’s USB port. It requires no additional power source. And it can restore your air silently and easily.
