You really have an mineral problem. I have pretty much same here. I only use bottle water that comes in gallon size from grocery. Ot is the only way I have found other than constand cleaners or a water softener. Good luck

If the water has been sitting in the reservoir for days without use, it may develop a film on the ultrasonic element which inhibits the creation of the mist to come out the top of your humidifier. I would lift off the tank and empty the reservoir. Then VERY GENTLY with a piece of paper towel, wipe the ultrasonic element (looks like a disk the size of a quarter at the bottom of the reservoir) to clean off any film. Then replace the tank and let the reservoir fill up the tank and try it again.

Good luck
