Owner's Manual & FAQs

Owner’s Manual: Reflection Cool Mist Humidifier (HUM900)

Question: How does the Honeywell Reflection Cool Mist Humidifier work? 

Answer: The Honeywell Reflection Cool Mist Humidifier is designed to quietly provide visible cool mist for dry air relief. This filter free humidifier features a nebulizer that quietly vibrates the water at an ultrasonic frequency, breaking the water droplets into an ultra-fine, cool mist that you can see and feel. The mist helps reduce dry air discomforts by increasing humidity levels to help you breathe better and sleep more comfortably.

Question: How do I set up/install my Honeywell Reflection Cool Mist Humidifier? 

Answer: Follow the step-by-step instructions below to set up your Honeywell Reflection.

  1. Remove packaging materials.
  2. Remove twist tie and extend power cord.
  3. Place on a firm, level, water resistant surface a minimum of 12” (30cm) from any walls. Mist should be directed away from any walls, bedding and furniture.

Question: How do I set the timer to program my humidifier to turn off after a certain number of hours? 

Answer: The timer feature allows you to program the humidifier to turn off after a specified amount of time, in one-hour intervals.  The timer is ON when the indicator above the Timer icon is illuminated in white. The Humidity Control arrows are used to increase or decrease the number of hours you would like to keep the humidifier running.   To turn the timer OFF, touch and hold the Timer icon for 2 seconds, or use the Humidity Control to decrease the time setting to zero. Pressing the power button or unplugging the humidifier will also rest the timer to ‘off’.
