Rheeman, I've had the Ionic Breeze for a year or 2. Obviously, it didn't stop me from getting pneumonia, which, in my case, is the root of the evil. Don't geet me wrong, I'm not knocking it, but I can't endorse it as a "cure all," either. In my case, I should probably rent a place in Arizona or New Mexico, each fall, until the leaves disappear.
