You got a humidifier right, not a dehumidifier? I don't mean to ask a silly question, I was just checking because a dehumidifier would take water out of the air and the reservoir would start out dry and fill up with water removed the air. A humidifier does the opposite - you fill the reservoir with water and it heats it and puts it out into the air. Do you mean it was just damp around the humidifier, like condensation or was it like puddles/pools of water around the humidifier when you returned?
