Query: Worst things about any type of eletronic air purifiers

I have done tons of research on these type of electronic air purifiers including have family members how bought these as well. First I like to say that study and test show that Ionic Breeze has the lowest ratings possible and are made very cheap even there $800. dollar models. Also that 3rd party manufacturers like Ionic pro to name a few are built and filter the air a lot better the Ionic Breeze(brand name) models.The downside Unless you like the smell of air being electronic discharged like the smell of a lighting storm and headaches to go along with it then I would recommend to stay away from these regardless of the brand. If you don't mind it then go buy any nock off model just stay away from Ionic breeze which is made cheap and they also live up to marketing hype and advertisements to rely on business. Just like Blue-Ray dvds. Don't take my word for it do the research and see your self.
