There is something terribly ironic about an air purifier emitting potentially harmful levels of ozone.

I've never owned one, is this really true?

Regarding the laptop cooler, I wonder how safe it is to have ionized air molecules around sensitive electronics in a computer. Is this a false worry?

It's a sick trick by the ozone generator manufacturers. Ozone generators should never be used in an occupied building.

"Avoid using air cleaning devices that emit ozone. Ozone has not been found to clean indoor air, including mold problems. Ozone can harm lung health, especially for children, the elderly, and people with asthma and chronic lung diseases."
