"A high-capacity humidifier whose main strength—its huge tank—is also its biggest chore."
The 1000ml/h mist output means it can rapidly increase humidity in a large open space, but it achieves this by turning a full liter of water into airborne vapor every hour it runs on high.
This is for someone in a large, open-plan loft or studio who values filling the tank infrequently above all else. If you are prepared for the rigorous weekly cleaning a tank this size demands, the capacity is a major convenience.
Anyone unwilling to commit to a strict cleaning schedule should avoid this unit, as a large, un-sanitized tank can aerosolize bacteria. Buyers in multi-room homes will get better results from several smaller, more manageable humidifiers.
