Ultrasonic humidifier Adler AD 7972 — 4 L tank, 300 ml/h, up to 35 m², 23 W, white

The Adler ultrasonic humidifier provides precise and convenient control of indoor humidity with an LED display and touch buttons. Its top-fill design simplifies refilling, and the device continuously monitors and shows current room humidity in real time. Ultrasonic technology generates a fine mist of 1–5 µm particles, and an aromatherapy function allows adding essential oils for pleasant breathing.

Advantages

The humidifier features an intelligent humidity control system that automatically starts or stops humidification when room humidity deviates by 5% from the set level. A built-in hygrometer allows setting target humidity between 40% and 90%. Safety is ensured by an advanced water shortage sensor that turns the unit off when the tank is empty. A timer offers automatic shutdown after 1, 2, 4 or 6 hours, and three intensity levels let you adapt output to room size. The 4.0 L water tank provides more than 13 hours of continuous operation on one fill.
