The problem with Ozone generating machines is just that - OZONE.
Reports have found that the ozone in a room with one of these devices is significatnly higher than with out.
For those worried - I would - Ozone is BAD for you, especailly at the levels indicated.
Also, as far as an air purifier...it doesn't work. It adds ozone to make it seem like it works but ALL third party tests have shown the air to not be any 'cleaner' than before the device was used.

Sharper Image pays $525,000 to end lawsuit against CU
Sharper Image Corp. has ended a product-disparagement lawsuit that it brought against Consumers Union, publisher of Consumer Reports, paying CU court-ordered attorneys’ fees and costs totaling $525,000.
Sharper Image sued after Consumer Reports judged the company’s Ionic Breeze Quadra air cleaner “ineffective” in an October 2003 report. A U.S. District Court dismissed the suit, ruling that Sharper Image had not shown our findings to be false. Because Sharper Image’s claims affected CR’s rights of free speech and press, the court ordered the company to pay our legal expenses. Sharper Image filed an appeal but later withdrew it, ending the legal action.
“Sharper Image’s decision to withdraw its appeal puts an end to a lawsuit that should never have been filed, over reviews that were truthful, carefully researched, and fairly stated,” said Jim Guest, president of Consumers Union. “This is a victory for every American concerned about the rights of an unbiased organization to test products independently, and to speak out in the interest of product performance and quality.”
