The Levoit Superior 6000S Evaporative Humidifier is a 6 gallon evaporative whole house humidifier with a 1,500 mL/h output for up to 3,000 ft², up to 72 hours of runtime and smart control. For more models, see our Humidifiers page.
Our Verdict
The 6000S is one of the strongest portable humidifiers you can buy. It can raise humidity across a large home quickly, and because it is evaporative, it does so with tap water and without white dust.
It is expensive, large and its filters are an ongoing cost. For a single bedroom, a smaller evaporative unit makes more sense.

Design
The 23L tank runs up to 72 hours on low fan speed, and the unit is designed to be easy to move and to fold for storage when the season ends.
An upgraded detachable pump makes deep cleaning simpler, which matters on a unit this large that may run all winter.
Controls
An improved sensor holds humidity within 5 percent, so the home does not become too dry or too damp.
Smart and voice control let you check and adjust it from anywhere, and Levoit says it optimized the airflow to lower the maximum noise.
Placement Tips
Set the humidifier on a flat, water-safe surface at least a couple of feet off the floor if you can, and aim the mist into open air rather than at walls, wood furniture, curtains or electronics. Keep it a few feet from the bed or crib so moisture spreads through the room before it reaches you.
Check the room with a hygrometer for the first few days. Most homes feel best between 40 and 60 percent relative humidity, and if windows start to fog or the room smells musty, turn the output down or let the auto mode hold a lower target.
Running Costs and Care
Running costs are low: a humidifier uses far less electricity than a space heater or air conditioner, and the main extras are water, any filters or wicks, and cleaning supplies. Warm mist models use more power than cool mist or evaporative units because they heat the water.
Empty and dry the tank when you can, and clean it at least once a week so bacteria and mold do not build up. Distilled or filtered water reduces white dust from ultrasonic units and slows scale in every type. Before storing it for summer, clean and dry every part.
How It Compares
Against the AIRCARE Canyon console, the Levoit has smart control, a sensor and higher listed output, while the AIRCARE has larger listed coverage and simple analog controls.
Against the Lacidoll 25L ultrasonic unit, the Levoit avoids white dust and wet floors, while the Lacidoll has a bigger tank and higher output for less money.
