ALLERGISTS: Ionic Breeze vs. Hepa Filter :please read question?

My dad bought us a Air Purifer from Oreck and it has been a dream. They told us that the Ionic Breeze is not what they claim to be. I believe them because from experience we have had not trouble with the Oreck. Also my Dad has Asthama and he says that he breathes better then he has in years. I can’t remember what they actually said about the Ionic Breeze but it wasn’t good. Check out the Oreck for youself
