Verdict

The LEVOIT Dual 100 is a compact 2-in-1 ultrasonic cool mist humidifier and essential oil diffuser featuring a 1.8-litre (0.48 gal) top-fill water tank, a 24W rated power output, and an effective coverage range of 107–260 square feet. Its main characteristics include Spiral Air Duct technology that delivers a fine mist up to 3 feet high at a rate of 220 mL/h, an automatic shut-off safety sensor, and three adjustable mist levels. Prominent pros include its whisper-quiet operation at 28 dB or less, an intelligent sleep mode that turns off indicator lights while automatically maintaining a comfortable 40%–60% relative humidity, and a wide-opening design that makes refilling and cleaning incredibly easy. However, notable cons include its modest capacity that restricts runtime to a maximum of 20 hours on low (and as few as 8 hours on high), the lack of a secure locking mechanism to attach the water tank to the base when carrying, and a small built-in LED indicator light that some users find slightly bright in pitch-black rooms.
