The line of Vornado air purifiers are produced in a factory from China. You'll notice in a search for "Vornado" that they also sell fans, humidifiers, and purifiers.
Reviews are mixed, including several that comment that vornado air purifiers "caught on fire" (although I don't believe that is a common occurance). They are sold in stores like Bed, Bath and Beyond.
The patented Vornado technology to circulate air in a "vortex" is a bit of hype, and makes me think they stole it from the Dyson vacuum concept. Again, if I was a college student on a limited budget I would buy one, but then I'd probably buy any inexpensive HEPA filter if I needed relief but didn't want to spend money for a better model"
