  • Details & Dimensions

    Both mist temperatures add necessary moisture to the air, and help ensure proper humidity levels in your home. Indoor humidity levels between 40-60% can help relieve cough and congestion, keep throat and nasal passages hydrated, temporarily relieve dry air discomfort, protect furniture, reduce static electricity and even keep plants healthier.   

    This Honeywell humidifier and vaporizer features Fusion Mist Technology which boils water and fuses it with cool mist to generate the ideal warm mist temperature. It also has 3 mist settings, a digital humidistat, 2-direction mist outlet, an essential oil cup (oil not included) and is ideal for large-sized rooms. It is filter-free, has a wide tank opening and up to 36 hour run time.

    During cold and flu season, when allergies kick in, or the air is simply just dry, you can rely on this humidifier for your entire family.

  • Manual & FAQs

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

    Answer: The Honeywell Ultra Dual Comfort Cool + Warm Mist Humidifier is designed to quietly provide visible cool and warm mist for dry air relief. Water is released from the Water Tank into the Reservoir. On cool mist setting, a Nebulizer vibrates at an ultrasonic frequency, and produces cool, ultrafine mist that travels up the Mist Chimney where it enters the room. On warm mist setting, water in the Boiling Chamber is boiled to create a steam vapor. On warm mist setting, the steam vapor mixes with a small amount of cool mist to produce soothing, warm (not hot) comforting mist.

    Question: Why is there white dust? 

    Answer: With an ultrasonic humidifier, a built-in nebulizer vibrates the water at ultrasonic frequency which causes the water droplets to break into a fine, cool mist that you can see. Naturally occurring minerals in your water get projected out with the mist and can settle around the unit in the form of white dust. In hard water areas, we recommend using demineralization cartridges with your ultrasonic humidifier to capture minerals in the water and to help reduce white dust on surfaces. You can also dilute tap water with distilled water to minimize white dust. 

    Question: Why does it sound different on warm mist setting than cool mist setting? ?

    Answer: The sound may increase on warm mist setting as the heating element warms up to boil water. Wait up to 5 minutes for water to boil then sound should decrease; sound will be slightly higher on warm mist setting.
