Medisana AH 663 - White - Humidifier

Medisana AH 663 - White - Humidifier is a modern ultrasonic humidifier designed to improve indoor air quality and comfort with precise control and a sleek design.

This humidifier uses ultrasonic evaporation technology to deliver up to 300 ml/h of moisture, making it suitable for rooms up to 20 m². The 4.5 L water tank gives long uninterrupted operation and supports up to 15 hours of continuous use on a single fill.

The AH 663 features an integrated humidity sensor and air quality sensors that monitor conditions and help maintain a recommended relative humidity between 45% and 75%. An accurate built-in hygrometer and LED display show current readings, so you can quickly check room conditions.

For convenience, the unit offers touch controls, a sleep mode for quiet nights, and a timer that can be set from 1 to 12 hours. Auto power-off adds safety by shutting the device down when water runs low or a preset time ends.

With a compact footprint (205 x 205 x 300 mm) and a lightweight body (1.18 kg), the Medisana AH 663 fits comfortably on bedside tables and shelves. It draws just 25 W from a standard 220–240 V, 50/60 Hz AC supply and uses a 1.4 m cord for flexible placement.

Typical use cases include improving bedroom comfort during dry seasons, maintaining optimal humidity for houseplants, and easing respiratory discomfort in small living rooms or home offices. The sleep mode and quiet ultrasonic operation make it particularly well suited for bedrooms.

Key selling points are the large 4.5 L tank, precise humidity control, long 15-hour operating time, and easy-to-read LED display. The combination of auto shut-off, touch control, and air quality monitoring gives a safe, user-friendly experience.
