The Boneco 1.5 Gal. Warm Mist/Cool Mist Humidifier can produce cool or warm humidity at the push of a button. In winter, warm mist prevents a drop in room temperature; in summer, cool mist provides pleasant freshness. The hygrostat controls the relative humidity, which can be set as required. The water output can be set using the output control. The mist can be distributed in the room in two directions using the double jet nozzle. The dimmer of the digital display enables particularly convenient nighttime operation. An empty indicator shows you when it is time to add water.
