The Cleanlon USB-powered air purifier

Somehow we missed this from the other day, but the New York Times actually reviewed one of those USB-powered air purifiers. The only thing about reviewing the Cleanlon is that they couldn't tell if it was really removing dust and bacteria from the air, though the odor of their PCs circuit board was reduced a bit. Which is kind of the frustrating thing about air purifiers — it's hard to tell right away whether they're actually doing anything, you just sorta have to take it on faith that the air around you is less bad than it was before.
