## Long description

The Medisana AH 663 Ultrasonic humidifier combines a 4.5 L water tank with quiet ultrasonic technology to stabilize indoor humidity levels. Its compact footprint (205 mm x 205 mm x 300 mm) and dual-tone housing in black and white fit modern interiors while the 25 W power rating and AC operation deliver continuous mist output for rooms of moderate size. An integrated LED display shows operating status and settings, making it simple to monitor and adjust humidification performance.
Advantages
The ultrasonic operation provides near-silent performance and fine mist distribution that humidifies air efficiently without heating. A 4.5 L water tank reduces refill frequency, and the compact design allows flexible placement on tabletops or shelves. The LED display gives clear visual feedback on settings, and the unit’s low power consumption (25 W) keeps energy use modest during regular operation.
Suitable for
Bedrooms and nurseries to maintain comfortable humidity during sleep
Living rooms and home offices to protect wooden furniture and indoor plants
Small to medium-sized rooms where compact appliances are required
Environments where quiet operation is essential, such as study spaces
