Owner's Manual & FAQs

Question: How does the Honeywell Ultra Plus Ultrasonic Cool Mist Humidifier work? 

Answer: The Honeywell Ultra Plus Ultrasonic Cool Mist Humidifier is designed to quietly provide visible cool mist for dry air relief. Water is released from the Water Tank into the Reservoir. A Nebulizer vibrates at ultrasonic frequency, breaking the water into a fine mist. The mist is quietly propelled by a fan up a vertical Mist Chamber to the Mist Outlet where the cool, visible mist enters the room. This humidifier will shut off when the water level is low or when the Tank is removed from the Base.

Question: How do I manually set the humidity level on my Honeywell Ultra Plus Ultrasonic Cool Mist Humidifier?  

Answer: Mist Output: Press the Mist Output icon to toggle between low, medium, and high mist level settings. A higher setting will deliver mist into the room at a higher rate. The water level in the Water Tank will decrease faster on a higher setting since more moisture is going into the air. A lower setting will provide less moisture output and run longer before the Water Tank needs to be refilled.
