Verdict

The Duux Beam 2 is a smart floor-standing ultrasonic humidifier featuring a 5-litre top-fill water tank, a mist output of 350 ml/h, and a power consumption of 27W, making it ideal for rooms up to 40 m² with a runtime of up to 25 hours. Key characteristics include an adjustable self-regulating hygrostat (40–90% range), built-in temperature and humidity sensors, a high-resolution LED display, and three distinct mist settings. Main advantages include ultra-quiet operation under 35 dB, multi-platform app control via Bluetooth/Wi-Fi with Alexa and Google Assistant compatibility, a detachable remote control that stores directly in the unit, and a dedicated compartment for aromatherapy oils. However, notable drawbacks include a risk of localized over-humidification if placed poorly, a reliance on periodic descaling maintenance, and occasional initial app connectivity or setup syncing issues reported by some users.
