REPLACING THE FILTERS
Through normal use, waterborne 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
humidifier by checking the FilterCheck
®
Indicator. After 60
minutes of use, FilterCheck
®
Indicator will move and indicate
your filter condition. A brand new filter will register in the
section reading GOOD filter. After frequent use of your
humidifier, the FilterCheck
®
Indicator will let you know when
the filters need to be changed, see Figure 2.
When the needle is in the CHANGE section, this means the
proper amount of moisture is not getting into your air due
to the excessive minerals and sediment that have become
trapped on your filters. At this point, you should replace
your filter. It is important to change your filter as indicated
to obtain stated performance level.
To replace the filter, follow the steps below:
1. Turn the unit off and disconnect from the electrical outlet.
2. Remove the tank from the housing.
3. Unlock the housing from the base by turning the lock
knob to the unlocked position.
4. Lift the housing straight up and place to the side.
5. Unlock the wick holder from the base by turning the
lock knob to the unlocked position.
6. Remove the wicks from the wick holder.
7. Follow the weekly cleaning instructions.
8. Insert new filters into the wick holder and lock the
wick holder back onto the base.
9. Replace the housing onto the base and lock it into place.
10. Fill the tank and place back into housing.
11. Repeat Operating Instructions.
It will take about 30 minutes for the humidifier to reach
maximum output.
You can purchase replacement filters (model HWF100-
UC2/HWF100 – 2 filters) at your local retailer, by calling 1-
800-546-5637, filling out the accessory card, or by visiting

THESE IMPORTANT SAFETY
INSTRUCTIONS
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.
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 to OFF and the unit
is 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 the
humidifier on a finished floor or near furniture, which
can be damaged by moisture or water. Place on a
moisture-resistant surface.
FILLING THE WATER TANK
1. Remove the tank from the housing of the humidifier by
grabbing the handle of the tank and pulling forward. Lift
the tank out of the housing and bring to the faucet. Turn
the tank upside down and twist off the tank cap by turning
counter clockwise. Fill tank with cool, fresh tap water. DO
NOT fill with warm water as this may cause leaking.
Replace the cap on tank FIRMLY.
2. When full, carry the tank to the humidifier and place
it into the housing. There is a locating tab located on
the tank base for easy guidance. The tank holds 1.3
gallons of water. The tank will immediately begin to
empty into the base.
3. Plug the power cord into a 120V AC electrical outlet.

the last setting the humidifier was set at.
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.
Extended Run Time Setting:
By setting your humidifier to a specific humidity level, you
are actually also extending the run time. Since the unit will
turn on and off to maintain the set humidity level, less
water will be used, so you will need to fill the unit less than
you would on manual setting.
