Disklavier

The system comes with a sheet of black plastic the covers the back of the piano to keep the humidity in. I don't think the Damppchaser humidifier is powerful enough to have any effect on the room or surrounding area with or without the plastic.

I have never worried about mold, but have no answer about that.

Raising the room RH will promote condensation build-up on the nearby windows during the colder winter months.  One of the primary reasons for wanting to have a Dampp-Chaser system installed is to compensate for the very low RH in the house during the winter months due to being forced to turn down the furnace humidifier to avoid excessive condensation / frost build-up on the windows, etc.
