Our take on the Viiwii 2L Ultrasonic Cool Mist Humidifier

The Viiwii 2L is a small ultrasonic cool-mist humidifier with a 2-liter tank, built for a bedroom, office desk or nursery. It runs quietly on ultrasonic misting and uses a cotton wick to draw water, so it needs a soak before first use and weekly cleaning. Against larger rivals it trades run time and tank size for a compact footprint; owners rate it well overall, though some note the wick and filter upkeep.
