Air-O-Swiss Travel Ultrasonic Humidifier 7146
The Air-O-Swiss 7146 humidifier is a compact, travel-friendly model. This ultrasonic cool mist humidifier does not include a water tank, rather it uses a standard water bottle which fits securely into the unit without leaks, while the ultrasonic technology makes operation very quiet. The unit is small enough to fit in any travel bag, and comes with a power adapter for both US and European plugs.
Although this compact humidifier will evidently not be effective at adding humidity to large rooms, it is an excellent choice for hotel rooms, an office, or even just a small room at home. Although it might seem a bit pricey for the size, the convenience and portability combined with the inclusion of adapters for travel make this an excellent choice.
