Compact ultrasonic humidifier with a 2.0L tank and filterless design. Runs up to 24 hours on low while operating below 26 decibels.


Overnight relief – thanks to a 2.0L tank and 200ml/h mist output

A 2.0L reservoir supplies water to the ultrasonic atomiser while the unit disperses around 200ml of mist per hour; low and high flow settings alter the run time to about 24 hours on low and roughly 10 hours on high.

Sustained mist helps maintain comfortable humidity through the night, reducing dry skin and easing nasal irritation for a better sleep.

Peaceful nights – with ultra-quiet ultrasonic operation and automatic indicator shut-off

Ultrasonic technology creates a fine mist without a fan, keeping acoustic output under 26 decibels; the indicator light switches off automatically after ten seconds of inactivity to avoid illumination in the dark.

Very low noise and dimmed indicators make the unit suitable for nurseries and light sleepers who are sensitive to sound and light.

Targeted comfort – with a 360° adjustable nozzle and four mist levels

A rotatable 360° nozzle directs the mist stream, while four selectable mist levels let users control how much humidity is released to match room size or personal preference.

Direct mist towards plants or sleeping areas to increase local humidity without over-wetting carpets or furniture, keeping conditions tailored and comfortable.
