Hey there,
When you say mylar tabs, are you meaning the orangey strips on the bottom of the ion bars? My machine makes a high pitched noise that I can hear (not everyone can though). I don't think those orangey strips or tabs are still on my ion bars.
Could this be my problem? I really hope so--I love my ionic breeze. I have an old Quadra model from about 2000.
Thanks,
Cade
