If your Ionic Breeze shows the red light that indicates it needs cleaning, you might have to take the entire unit apart to get it to work. I did that and found the two brass contacts inside the bottom of the unit were extremely dirty. Cleaned those and put everything back together and it works fine. It was a tedious job but it got the unit working. Here's a link that could help you restore your unit.
