An NSA air cleaner is cheaper and light years better. You can get a new one on Ebay for around $20 or 30. They employ a carbon filter and remove many more contaminants than the Sharper Image machine.
I use them at home and at work since my wife is very susceptible to allergies. Gross anatomy required two years of standing over a formaldahyde soaked corpse. Her immune system has suffered from that, and the air cleaners work wonders.
