I am told to only use distilled water in the Humidifier. However what would adding a small amount of mint flavoring to the water? Or perhaps dap of scope or your favorite mouthwash.. 
I wouldn't add anything to your water tank unless you want these products down in your lungs. That's not something I would want! Instead, there are some members that use different aromatherapy products on the outside of their machines (not in the tank). If you do a search on this board you will find many posts on this subject.
