HOW COOL MIST WORKS
Your Holmes Cool Mist humidifier draws dry air through the rear
air intake grill area. This air is then passed through a moisture-
laden wick filter, which retains the minerals and deposits in the
water. The resulting moist air is directed back into the room from
the top air grill.
NOTE: This humidification system provides a cool, invisible
moisture output. It is normal not to see the mist.
NOTE: A humidity level below 20% can be unhealthy and
uncomfortable. The recommended humidity level is between
40%-50%.
PRE-OPERATING INSTRUCTIONS
1. Be sure the humidifier is switched OFF and disconnected from
the electrical outlet.
2. Select a location for your humidifier, on a flat surface, about 4"
away from the wall. Do not place your humidifier on furniture;
a floor location that will not be damaged by moisture is best.
3. Remove the water tank by holding the tank handle and lifting
straight upward (see Figure 1 and 2).
4. Remove the main housing by lifting straight upward. Check to
see that the wick filter is properly in place. Replace the
humidifier housing.
FILLING THE WATER TANK
NOTE: This humidifier holds about 1.4 gallon of water in the
tank and humidifier base. The humidifier will produce up to 3.0
gallons of moisture over a 24-Hour period, depending on the
room humidity and temperature.
1. Be sure the humidifier is switched OFF and disconnected from
the electrical outlet.
2. Remove the tank from the base by holding the handle and lift-
ing straight up (see Figure 1 and 2).
3. Twist off the tank cap located on the bottom of the tank by
turning counter clockwise and fill the water tank with cool,
fresh water. Do not fill with warm water as this may
cause leaking.
4. After filling the tank, replace the tank cap by firmly turning
clockwise and then replace the water tank on the base. The
tank will immediately begin to empty into the base.
5. Plug the power cord into a 120V AC electrical outlet.
OPERATING INSTRUCTIONS
1. Move the Humidity Control Knob to the HI position. Move the
Humidity Control knob to the LO setting to lower the humidifi-
cation rate. Allow up to 30 minutes for the filter to fully absorb
water and the unit to produce the maximum moisture output.
NOTE: We recommend the use of the hygrometer which you can
purchase by calling 1-800-5-HOLMES. A humidity level below
20% can be unhealthy and uncomfortable. The recommended
humidity level is between 40% and 50%.
2. When the water tank is empty, and the base is almost empty,
you need to refill the tank. The fan will continue to run to help
dry the humidifier. Shut off and unplug the unit. Please follow
the Daily Cleaning Instructions. Refill the tank as directed in
Pre-operating Instructions.
3. Make sure the unit is switched OFF, then plug into the electri-
cal outlet. Turn the power ON.
If you do not plan to use the humidifier for two or more days,
make sure any residual water is drained from the water tank,
base and wick filter to prevent algae or bacteria growth.
REPLACING THE FILTER
Through normal use, water borne minerals and sediment become
trapped in the wick filter. The harder your water, the greater the
amount of minerals in the water, and the more often you will
need to change your filter.
You will be able to monitor the life of the filter in your humidifi-
er by checking the FilterCheck
®
Indicator. When the unit is off,
the FilterCheck
®
Indicator will read in the OFF position. After 60
minutes of use, FilterCheck
®
Indicator (refer to Figure 3 for
close-up of indicator) will move from the OFF position and indi-
cate your filter condition. A brand new filter will register in the
blue section reading GOOD filter. After frequent use of your
humidifier, the FilterCheck
®
Indicator will let you know when the
filter needs to be changed.
When the needle is in the light blue
(CHANGE) section, this means the prop-
er amount of moisture is not getting
into your air due to the excessive min-
erals and sediment that have become
trapped on your filter. At this point, you
should replace your filter. It is impor-
tant to change your filter as indicated to
obtain stated performance level.
To replace the filter, follow the steps below.
1. Be sure the humidifier is switched OFF and disconnected from
the electrical outlet.
2. Remove the tank and main housing to access the base tray
(see Figures 1 and 2).
3. Discard the old filter and follow weekly cleaning instructions.
4. Insert a new filter into the filter support in the base (Figure 2).
5. Replace the main housing and then the tank.
6. Repeat Operating Instruction steps.
It will take about 30 minutes for the humidifier to reach
maximum output.
NOTE: You can purchase replacement filters (model HWF64)
at a local retailer, by calling 1-800-5-HOLMES, filling out the
accessory card, or by visiting www.holmesproducts.com. It is
recommended that a replacement filter is purchased for uninter-
rupted use.
CLEANING AND MAINTENANCE INSTRUCTIONS
Humidifiers provide comfort by adding moisture to dry indoor
air. To get the most of the benefit from the humidifier and avoid
product failure, follow all maintenance instructions carefully.
If the recommended care and maintenance guidelines are not
followed, micro-organisms may be able to grow in the water
within the humidifier.
Daily Maintenance
1. Be sure the humidifier is switched OFF and disconnected from
the electrical outlet.
2. Lift off the tank and the housing of the humidifier. Remove
filter and place in sink or tub as the filter will release water
when not in the humidifier.
3. Carry the base and the tank to the sink, remove the wick
filter, then drain and rinse the base and tank thoroughly to
remove any sediment and dirt. Wipe clean and dry with a
clean soft cloth or paper towel. (DO NOT use metal cleaning
utensils or abrasive cleaners)
4. Put the filter back in the filter supports, replace the housing,
then refill the tank with cool tap water as instructed in filling
the water tank instructions.
Weekly Maintenance
Remove scale:
1. Repeat steps 1-3 above.
2. Clean the base by partially filling the base with one 8-oz cup
of undiluted white vinegar, or by using CleanseClean
®
by
Holmes. Let solution stand 20 minutes, clean all interior
surfaces with a soft brush.
3. Dampen a cloth with undiluted white vinegar and wipe out
entire base to remove scale.
4. Rinse with clean warm water to remove scale and the white
vinegar solution before beginning to disinfect the tank.
Disinfect tank:
1. Fill tank with 1 teaspoon of chlorine bleach and 1 gallon of
water.
2. Let the solution stand for 20 minutes, swishing every few
minutes. Wet all surfaces.
3. Empty the tank after 20 minutes, and rinse well with water
until the bleach smell is gone. Dry with a clean cloth or paper
towel.

NEVER put the cord under rugs or near heat registers.
4. DO NOT place humidifier near heat sources such as stoves, radi-
ators, and heaters. Locate your humidifier on an inside wall
near an electrical outlet. The humidifier should be at least 4”
away from the wall for best results.
5. NEVER place humidifier in an area where it is accessible to chil-
dren. NEVER use humidifier in a closed room, particularly where
a child may be sleeping, resting, or playing (a closed room may

Consumer Safety Information
NOTE: This is an electrical appliance and requires attention when
in use.
NOTE: If moisture forms on the walls or windows of the room,
turn off the humidifier. The room already has plenty of humidity
and additional moisture may cause damage.
NOTE: DO NOT block air inlet or outlet.
Cord and Plug Installation Safety Instructions
The length of cord used on this appliance was selected to reduce
the hazards of becoming tangled in, or tripping over a longer
cord. If a longer cord is necessary an approved extension cord
may be used. The electrical rating of the extension cord must be
equal to or greater than the rating of the humidifier. Care must
be taken to arrange the extension cord so that it will not drape
over the countertop or tabletop where it can be pulled on by
children or accidentally tripped over.
