The Levoit LV600S is the smart, quiet pick for a large bedroom. This ultrasonic hybrid puts out a surprising amount of vapor, which TechGearLab says lets it truly handle large spaces, and it offers both warm and cool mist through dual aimable nozzles. It runs as low as 26 dB and pairs with a smart app. Its 753 sq ft coverage is far below the consoles here and ultrasonic misting wants distilled water, but for a quiet, connected large bedroom it excels.
