$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. Its 753 sq ft coverage is the smallest here and ultrasonic misting wants distilled water, but for a quiet, connected large bedroom it excels.

Strengths
  • Puts out a large amount of vapor for an ultrasonic unit; TechGearLab calls it able to truly handle large spaces
  • 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

$249.99as of Jun 7

The Levoit Superior 6000S is the best large-room humidifier we'd buy. Its 6-gallon tank covers up to 3,000 sq ft and runs up to 72 hours between refills, and because it is evaporative it uses ordinary tap water with no white dust. Bob Vila named it the best overall evaporative model, praising weekly refills even on auto. It is quiet and app-controlled. The trade-off is replaceable wick filters and a bulky console, but for whole-room coverage it leads.

Strengths
  • Huge 6-gallon tank covers up to 3,000 sq ft and runs up to 72 hours on low before a refill
  • Bob Vila's best-overall evaporative pick; refill about once a week even running on auto
  • Evaporative design works with tap water and produces no white dust or wet film near the unit
Watch-outs
  • Wick filters need periodic replacement, an ongoing cost evaporative units share
  • Tall, bulky console takes up real floor space
  • Some owners find the smart app fussier than the hardware

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.

Levoit Superior 6000S Smart Evaporative Humidifier

The largest-coverage smart unit here, edging the Aircare MA1201 console on app control and quiet operation while matching it for whole-room reach. It covers far more than the Vornado Evap40 or the ultrasonic Levoit LV600S, and its evaporative design avoids the white dust that the LV600S can leave with hard tap water.
