Important Safety Instructions
READ AND SAVE THESE IMPORTANT SAFETY INSTRUCTIONS BEFORE USING THIS HUMIDIFIER
When using electrical appliances, basic precau-
tions should always be followed to reduce the
risk of fire, electrical shock and injury to people,
including the following:
1. The humidifier should ALWAYS be placed on a
firm, flat, waterproof surface at least four feet
(1.2 m) away from bedside, 12 inches (30 cm)
from the wall and out of reach of children and
pets. Be sure the humidifier is in a stable position
and the power cord is away from heated surfaces
and out of the way to prevent the humidifier from
being overturned.
2. The humidifier should not be left unattended in
a closed room. Doing so may result in personal
injury or property damage. Leave room door
partly open.
3. DO NOT aim Mist Outlet directly at children, walls
or furniture.
4. Before using the humidifier, extend the cord and
inspect for any signs of damage. DO NOT use the
unit if the cord has been damaged. DO NOT
operate with power cord coiled or with twist tie
in place.
5. The humidifier has a polarized plug (one blade
is wider than the other) as a safety feature. This
plug will fit into a polarized outlet only one way. If
the plug does not fit fully into the outlet, reverse
the plug. If it still does not fit, contact a qualified
electrician. DO NOT attempt to defeat this safety
feature.
6. CAUTION: To avoid fire or risk of electrical shock
hazard, plug the humidifier directly into a 120V AC
electrical outlet. To avoid risk of fire, electric shock
or personal injury, DO NOT use an extension cord
or power strip.
7. The humidifier should ALWAYS be unplugged
and emptied when not in operation or while being
cleaned. Shut-off and unplug humidifier before
moving. DO NOT move or tilt humidifier while it is
in operation. Plug and unplug unit with dry hands.
NEVER pull by cord.
8. DO NOT operate the humidifier without water. Turn
off and unplug unit when Tank is empty.
9. The humidifier requires regular cleaning. Refer to
and follow cleaning instructions provided in the
Owner’s Manual.
10. DO NOT operate outdoors; this humidifier is
intended for indoor residential use only.
11. DO NOT cover or insert objects into any openings
on the unit.
12. DO NOT block intake or output vents.
13. DO NOT attempt to repair or adjust any electrical
or mechanical functions on this humidifier. Doing
so will void your warranty.
14. DO NOT place in direct sunlight, high temperature
areas or near computers or sensitive electronic
equipment.
15. DO NOT touch the nebulizer while the unit is
plugged in as burns could result.
16. DO NOT add any essential oils or medications
(e.g. Vicks VapoSteam®) into the Water Reservoir or
Water Tank. Doing so could damage the humidifier
and void the warranty.
17. For residential use only.

How Your Humidifier Works
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.

Filling/Refilling
You have two options for filling your humidifier’s
Water Tank: under the faucet at the sink, or
with a pitcher of water at the humidifier.
1. If filling at the sink, turn the humidifier off, then
open Tank lid to reveal the handle, remove Tank
from Base, carry to sink and fill.
OR
If filling at the humidifier, ensure Tank is securely
seated on Base. Open Tank lid and fill using a
water pitcher.
NOTE: Fill Tank with cool water. DO NOT fill with
warm or hot water. DO NOT ADD ESSENTIAL OILS,
MEDICATIONS, OR INHALANT LIQUIDS, such as
Vicks VapoSteam, to the Tank. Doing so could cause
damage to the humidifier and void the warranty.
2. Close the Tank lid.
3. If filled at the sink, carry the full Tank back using
two hands and place back in the Water Reservoir
on the Base. For proper placement, line up the
chimney and nozzle to the HONEYWELL logo.
NOTE: When taking your Tank to and from the sink, carry
the Tank using two hands. Manufacturer will not accept
responsibility for property damage caused by water spillage.
Water Quality and Your Humidifier
High mineral content in your water, also known as
“hard water,” may cause a white mineral residue
to accumulate on surfaces in the room near the
humidifier. This mineral residue is commonly
referred to as “White Dust.” The higher the mineral
content or hardness of your water, the greater the
potential that you may have white dust. “White Dust”
is not a result of a defect or flaw in the humidifier. It
is a result of the amount of minerals suspended in
the water you are using. If you live in a hard water
area, use distilled water to minimize the production
of white dust.
CAUTION: USE CARE WHEN HANDLING WATER
TANK TO AVOID UNNECESSARY IMPACT. BANGING
OR DROPPING THE WATER TANK COULD RESULT IN
DAMAGE TO THE TANK THAT WILL CAUSE LEAKING.
06
Operating the Humidifier
Power: Plug the humidifier into a polarized 120V
outlet. Press the Power Recess to turn the
humidifier on. The Power icon will illuminate white
when the device is on.
CAUTION: TO AVOID ELECTRIC SHOCK DO NOT
PLUG HUMIDIFIER INTO OUTLET WITH WET HANDS.
If the Power icon turns an amber color, this indicates
that the Reservoir water level is low or the Tank is not
set in place. Check the water level and fill if necessary,
and ensure the Tank is properly seated.
NOTE: If the Tank is refilled at the humidifier when the Power
icon is amber, it will need to be reset. Either power OFF then
ON or remove and replace the Tank. This will activate the
water flow to the Reservoir and turn the Power icon white to
indicate normal operation.
Humidity Display: While the humidifier is running,
the display will remain white until the set humidity
level is reached.
Humidity Reached Icon: Once the set humidity level
is reached, the display will turn blue, the Humidity
Reached icon will illuminate and the unit will stop
producing mist.
If there is no water in the reservoir, the display will be
white and the Power icon will be amber.
Auto Mode: Your humidifier is equipped with an
Auto Mode that allows for effortless humidification.
When first powered ON, the humidifier will start in the
Auto Mode. The humidifier will automatically set the
humidity output level based on the ambient relative
humidity in the room. When the humidity level is low,
the humidifier will add more moisture to the air at
a faster rate by automatically using the Turbo Mist
feature. The target humidity level in the Auto Mode is
60%. Once the humidity reaches 60%, the humidifier
will stop producing mist while continuing to monitor
the humidity level around the device.
Humidity Mist Level: You can control the amount of
mist that you would like the humidifier to produce. To
manually select a mist level, touch the Mist Control
icon . Continue to touch the icon to change the
mist level setting. The selection will cycle through
Auto -> Low -> Medium -> High -> Auto. The setting is
indicated by the illuminated indicators above the Mist
Control icon .
07
Humidity Level Setting: As an alternative to using
the Auto Mode, you can set your preferred humidity
level manually. Select the Low, Medium or High mist
level, then use the Humidity Control arrows to set
your desired humidity level. You can set the humidity
level from 30% to 69%. For personal comfort, the
recommended humidity level is between 4060%.
If the humidity level in your space drops below
30%, the Display will show .
If the humidity level rises above 69%, the Display
will show .
Adjust the humidity level up or down as desired.
Humidity Reached Icon: When the desired humidity
level is reached, the Humidity Reached icon and
numeric display are illuminated in blue.
NOTE: If you notice condensation on the walls, windows or
around the humidifier, your humidity level is too high. Lower
the setting or turn off the humidifier.
Timer: The timer allows you to program the humidifier
to automatically turn off after a specified time. To set
the timer, press the Timer icon . The LED above
the icon will blink white and the numeric display will
change to show the hours to set the timer. Use the
Humidity Control arrows to increase or decrease the
Timer setting by 1 hour intervals, up to 12 hours.
The timer is ON when the indicator above the Timer
icon is illuminated in white. To turn the timer OFF,
touch and hold the Timer icon for 2 seconds,
or use the Humidity Control arrows to decrease the
time setting to .
NOTE: While the timer is running, the humidifier will
continue to cycle ON and OFF to maintain the set humidity
level. At the end of the timed cycle, the humidifier will power
OFF, regardless of the humidity setting. If the humidifier
is manually turned off by pressing the power button or by
unplugging the humidifier, the timer will reset to OFF.
Tank Light: The tank light creates a soft, ambient
glow in your space and also helps illuminate the
level of water in the humidifier. To turn ON
the tank light, touch the Tank Light icon . Touch
again to dim the light, and touch a third time to turn
OFF the light.
Mist Outlet: The Mist Outlet is designed to let you
direct your humidification exactly where you want.
Turn the Outlet a full 180 degrees to direct the mist
according to your preference. It will not rotate to direct
mist behind the unit to avoid white dust ingestion in
the rear input vent.
