Philips HU4210/04 Ultrasonic humidifier 3.5L 3W white

The Philips HU4210/04 is a compact and energy-efficient humidifier designed to maintain optimal indoor humidity levels in medium-sized rooms. It uses evaporative humidification technology (NanoCloud system), which helps reduce the spread of bacteria and prevents white dust on surfaces.

With a 3.5 L water tank and a humidification output of about 300 ml/h, the device can operate for long periods without frequent refilling. It is suitable for rooms up to approximately 44 m².

The humidifier operates very quietly (down to ~25 dB), making it suitable for bedrooms and children’s rooms. It includes automatic humidity control, timer, sleep mode, and safety auto shut-off.

Thanks to its low power consumption (3 W) and universal 100–240 V AC support, it is energy efficient and travel-friendly.
