## Summary description

Adler AD 7972 is an ultrasonic floor humidifier with a 4 L water tank and maximum output 300 ml/h, suitable for rooms up to 35 m². Features include automatic mode with humidity sensor (40–90% RH), 3 speeds, timer, sleep mode, touch control and LED display. Low-noise operation (35 dB), 13 h runtime, 23 W power and auto shut-off provide convenient daily use.

## Long description

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.

If water runs out, the unit will switch off automatically.
Recommendations
For best results, use clean tap or filtered water and clean the water tank regularly to prevent buildup. Place the humidifier at least 20–30 cm away from walls and electronic devices. Do not add undiluted substances except recommended essential oils for aromatherapy. Follow the user manual for maintenance and safety instructions.
