Capacity and Runtime

The 1.5 gallon tank delivers up to 18 hours of continuous operation. At a moisture output above 300 ml per hour it suits medium bedrooms or offices. The automatic shut-off activates when the tank empties, preventing dry running.

Mist Control and Air Quality

Adjustable mist volume lets you match humidity to room conditions. A built-in ionizer with indicator light runs alongside the ultrasonic mist to reduce airborne particles. Whisper-quiet operation keeps noise low enough for overnight use.

Tank Design and Timer

The transparent removable tank has a carry handle for easy refilling at any sink. A refill light signals when water is low. An integrated timer offers 2, 8 or 12 hour settings for scheduled operation.

Questions about this item

Will the 1.5 gallon tank fit on the same shelf as my older humidifier?

The unit has a transparent tank with a handle and measures 1.5 gallons, so compare those dimensions with your existing shelf space.

How do I know the ionizer is actually running after I turn it on?

A dedicated indicator light on the front panel illuminates whenever the built-in ionizer is active.

Does the package include a replacement filter or do I need to buy one separately?

The box contains the humidifier base, the removable 1.5 gallon tank, and the user manual; no filter is included or required for this ultrasonic model.
