A new technology has made giant air cleaners in Swedish factories smaller and more energy-efficient, and now it's doing the same for filters in your home. The innovation: paper.
Many purifiers, both industrial and residential, clean the air by giving pollutants an electric charge and trapping the staticky gunk with oppositely charged metal plates. Humanscale's tabletop Humanair replaces metal with strips of paper coiled into a foot-wide spiral. The paper attracts dirt like metal plates do, because charged lines of metallic paint run along one side of the strips. But the nonconductive layers of paper can be packed just 0.06 inch apart without creating sparks, so the paper traps more grit. It squeezes 14 square feet of filth-catching surface—at least twice as much as other electronic home purifiers—inside a 15-by-13-by-4-inch case.
Since the Humanair is so skinny, it needs only low-power fans to nudge air through. And with the small current it uses to charge dust, it sips just 17 watts, making it the most efficient way to bring industrial cleaning power to your personal space.

Good idea. Make it affordable and it will sell quite well. If it needed to be a higher price, it could be high-quality to justify its existence.
it sips 17 watts per what (day, hour, year, second)? What is the CADR? (clean air delivery rate), or how well does it work? It claims to use ionization as the main filtration method, so does it produce ozone (a toxic chemical )like all of the other ionization filtration gadgets? How much does a new ream of paper (filter) cost? What is the cost of the unit? How much does a carbon filter cost?
