I've got an ionic pro, the more reasonable priced version of the ionic breeze(the compact 18" version, as it's in a small room). It works very well except that it releases ozone(o3 i think? some people refer to it as the smell of ions, but with the ionic pro it is really ozone) . Some people complain of headaches but I nor anyone who's been in the same room have noticed anything, and you just wipe the metal collection blades down and put them back in(I wash them every few days though(they are just metal and plastic, completely safe to wash)).
I'd say if you've got the money to burn go with the Ionic breeze, otherwise go for the Ionic pro(or the ionic pro compact.)
They're gonna get me sooner or later, let's just hope it's later. -GG Allin
