This humidifier uses ultrasonic technology to produce safe, cold steam, making it ideal for warm climates. It features an adjustable steam flow and a small top water tank for spreading essential oils. With 8 hours of autonomy and automatic shut-off, it helps restore proper humidity levels, easing coughs, colds, and dry skin conditions like eczema. The cold mist helps loosen mucus and moisturize the mucous membranes, promoting better breathing, especially in dry weather.
