The Levoit LV600S is a mid-range humidifier intended for use in large rooms, with an advertised coverage of 753ft². It boasts a unique hybrid misting system that combines steam and evaporative systems, allowing you to tailor its settings for either warm, humid areas or cool, dry rooms.

Our Verdict

7.0 Home

The Levoit LV600S is a decent home humidifier. It provides impressive overall humidification capacity, making it suitable for use in large rooms. You can simply set the desired humidification level and leave it alone using the physical interface, the Vesync companion app, or voice commands. Combined with its 17-hour runtime, this unit won't require much in the way of babysitting. That said, it does have quite a few components that need to be washed periodically, so cleaning the unit out can be a long and tedious process, even with the included cleaning brush and large top-fill tank opening.

Pros
  • Wide array of smart features.

  • Long runtime.

  • Impressive overall capacity.

  • Impressively low operating noise.

  • Low energy consumption in cool mist setting.

Cons
  • Demanding maintenance requirements.

7.3 Bedroom

The Levoit LV600S is decent for use in bedrooms. It's relatively compact and pretty quiet, so you can set it up on a small nightstand close to your hand without any worry that it'll keep you up. You can even turn off the LED display so there are no bright lights that you'll need to contend with. It offers sufficient runtime to operate throughout the night without running out of water, and its high capacity allows it to humidify larger bedrooms without breaking a sweat. On the downside, it has a lot of parts that need to be cleaned periodically, some of which are a hassle to clean properly.

Pros
  • Wide array of smart features.

  • Long runtime.

  • Impressively low operating noise.

  • Low energy consumption in cool mist setting.

Cons
  • Demanding maintenance requirements.

4.5 Cleaning

The Levoit LV600S is difficult to clean. It has many parts that need to be cleaned manually, all of them by hand. There are also quite a few spots where it can be difficult to squeeze in a hand or fit a brush.

Pros
Cons
  • Demanding maintenance requirements.

8.5 Capacity

The Levoit LV600S has impressive humidification capacity. It won't have too much trouble quickly adding moisture to large, open-concept spaces.

Pros
  • Impressive overall capacity.

Cons
8.0 Humidifier Efficiency

The Levoit LV600S' overall efficiency depends on the mode in which you run it. In its cool mist setting, it outputs a pretty significant amount of steam relative to its power draw. However, its power consumption skyrockets when it's set to its warm mist setting, though that would also offset the cost of having to heat your home in cooler, dryer months.

Pros
  • Low energy consumption in cool mist setting.

Cons
  • High power consumption in warm mist setting.

The Levoit LV600S is only available in a single colorway: 'White.' For those interested, here's the label for the unit we tested.

Let us know in the discussions below if you come across another variant of this humidifier.

Compared To Other Humidifiers

The Levoit LV600S is a smart humidifier with a unique hybrid design that allows it to output cool or warm mist. It's packed to the gills with features, including a humidistat, Wi-Fi connectivity, and an essential oil tray. Its humidification capacity is nothing to sneeze at either, as it'll quickly add moisture to even larger spaces like apartments or open-concept living spaces. The only fly in the ointment is its complicated design, making it a substantial annoyance to clean.

The Levoit LV600S is quite a bit of a hassle to clean. There are 18 separate components that need to be washed periodically, none of which are dishwasher safe and consequently have to be hand-washed. The main body needs to be cleaned thoroughly, and there are many sections where it can be difficult to squeeze in a hand or fit a brush. Thankfully, the large tank opening makes cleaning a little easier.

The Levoit LV600S works as a hybrid ultrasonic and steam humidifier unit. During startup, it defaults to the cool mist mode, which you can switch to the steam mode by tapping the 'Warm' button.

You can simply set the desired humidity level using the 'Humidity' button on the front panel. The unit will release mist until that level is reached and then pause.

This unit can also be operated using the Levoit VeSync companion app, which allows you to operate the device completely remotely. The app also integrates with Amazon Alexa and Google Assistant, allowing you to make changes to the humidifier's settings using only voice commands.

This unit's humidification capacity differs only slightly when it's used in its warm mist setting:

  • Water Emitted by the Humidifier: 190 ml (6.4 oz)
  • Tested Humidification Capacity: 9.0 LPD

This humidifier's efficiency varies depending on the setting. In its cool mist mode, its power consumption is pretty negligible. However, If you run this unit in its warm mist setting, its humidification efficiency drops considerably. Below are the findings for this test with the unit set to its warm mist setting.

  • Humidifier Energy Consumption: 136 Wh
  • Humidifier Electrical Efficiency: 1.0 l/kWh

External efficiency differs when this unit is run in its warm mist setting, with the energy required for evaporation dropping since maintaining humidity at 60% won't cool the room you're in. You can see the results of this test in that setting below:

  • Water Evaporated by the Environment: 164 ml (5.5oz)
  • Energy Required For Evaporation: 0 Wh
  • Overall Electrical Efficiency: 1.1 L/kWh

It's worth noting that the result for the 'Noise @ Highest Setting' test was achieved in the humidifier's warm mist mode, with the highest heat and misting settings. Running the Levoit LV600S in its cool-mist mode at its highest misting setting yields a max operating noise of 32.0 dBA. The result for the 'Noise @ Lowest Setting' test was achieved with the unit in its cool mist-only mode at the lowest misting setting.
