Key features
Cool or Warm Mist Ultrasonic Humidifier
You can choose cool mist year-round or warm mist for winter months to help alleviate dry skin, sinus congestion, allergies, cold and flu plus help reduce static electricity caused by dry air. NOTE: Warm Mist will feel cool to start but will feel warmer after 30 minutes of use.
Easy to Use
Comes fully assembled. Dual nozzles spin 360° directing the vapor in any direction. Removable tank fills easily. Distilled water best but tap water is fine. No filters to replace. Electronic controls let you choose from 3 mist flow settings and warm or cool options, adjust the LED lighting and humidistat and set the 12-hr timer. Automatically shuts off when empty.
High Capacity Comfort
This portable dual mist humidifier runs up to 100 hours on LOW for cool and up to 75 hours on LOW for warm. On HIGH, this humidifier outputs cool moisture up to 10oz/hr and warm moisture up to 13.5oz/hr. It will handle large or small rooms up to 600 sq. ft. and is best used in bedroom, kids room, baby nursery, or wherever relief is needed.
Soothing Humidity Day and Night
According to the Mayo Clinic, indoor humidity levels between 30% to 50% are best and can help soothe dry air problems of the skin, throat, and sinuses. Proper humidity levels can also improve sleep. Digital humidistat lets you customize and maintain your desired humidity level from 40% to 75%. Great for guitars and indoor plants, too.
