Levoit LV600S 6L Smart Warm and Cool Mist Humidifier

4.3

$109.99as of Jun 7

The Levoit LV600S is the smart, quiet pick for a large bedroom. It is an ultrasonic hybrid that puts out a surprising amount of vapor, which TechGearLab says lets it truly handle large spaces, and it offers both warm and cool mist with dual aimable nozzles. It runs as low as 26 dB and has the most affordable smart app of the group.

— Both warm and cool mist, plus dual 360-degree nozzles to aim the output
— Very quiet, as low as 26 dB, with a dedicated sleep mode

Watch-outs

— Ultrasonic misting can leave white dust if you use hard tap water; distilled water is recommended
— 753 sq ft coverage is the smallest in this roundup
— Tank can be awkward to clean thoroughly

How they stack up

Levoit LV600S 6L Smart Warm and Cool Mist Humidifier

The only ultrasonic and the most affordable smart unit here, the pick when you want warm-mist capability and app control in a large bedroom rather than the whole-house reach of the Levoit Superior 6000S or Aircare MA1201. It covers less area than every other unit and, unlike the evaporative Vornado Evap40 and Aircare consoles, can leave white dust with hard water.

Vornado Evap40 4-Gallon Evaporative Humidifier

The best single-room value here, covering up to 1,000 sq ft, less than the Levoit Superior 6000S or the Aircare MA1201 consoles but more affordably and with the most even air circulation thanks to Vornado's Vortex design. It is evaporative like the Aircare units, unlike the ultrasonic Levoit LV600S, and carries the longest warranty of the group.
