KSHM-260RA-T model humidifier for sale. I purchased this last winter and only used it during the winter. I'm selling it because the boiling sound bothers me. Fill the tank with water and wait a while for the steam to come out. There are signs of use on the bottom of the tank. Please be careful as the steam outlet gets hot. Please note that purchases made on or after the 25th will be shipped on or after December 13th. - Model Name: KSHM-260RA-T - Voltage: AC100V - Power Consumption: 210W - Auto Shut-off: Yes Thank you for looking.
