- Warm and cool mist options with separate level settings offer flexibility across seasons and room conditions.

What to know before buying
Listing details to confirm
The listing identifies the unit as ultrasonic and gives a 20-liter capacity, 2,500-square-foot coverage, and 72-hour runtime, but these performance figures are manufacturer claims and depend on operating conditions. The feature text also mentions a 5.3-gallon tank, 40% to 90% humidity settings, three output levels, warm mist at 104 to 106 degrees, and operation under 35 dB. These details are not all repeated in the structured specifications, so confirm the exact configuration and mode-specific claims for the selected listing. The product details list a demineralization cartridge, while the explicit contents list does not specify one.
