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. The
FilterCheck
®
Indicator will only read the filter condition
when the humidifier is in operation.
NOTE: It may take up to 60 minutes of operation for
the FilterCheck
®
Indicator to reflect the 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 and main housing to access the base tray.
3. Remove wick and discard.
4. Follow the weekly cleaning instructions.
5. Insert new filter.
6. Repeat Operating Instructions steps.
It will take about 30 minutes for the humidifier to reach
maximum output.
NOTE: You can purchase replacement filters (model
HWF75/HF221) at a local retailer, by calling
1-800-546-5637, or by visiting
www.holmesproducts.com.
It is recommended that a replacement filter is purchased
for uninterrupted use.

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 (refer to the rating
artwork placed on 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 inches (10 cm) 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.
3. Humidifier can be used with or without wheels.
Locate the four wheels in the box. Turn base of
humidifier over to reveal underside. Locate the two
stationary wheels and push the wheel posts into one
end of the base (Figure 1). Locate the two swivel
wheels and push the wheel posts into the opposite
end of the base (Figure 1).
FILLING THE WATER TANK
1. Remove the tank from the base of the humidifier
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 each tank
FIRMLY.
2. When full, carry each tank to the humidifier and
place onto the base (use both hands when carrying
each tank). Each tank holds 1.6 gallons of water, and
the base holds 1/2 gallons of water.
3. Plug the power cord into a 120V AC electrical outlet.

stoves, radiators, and heaters. DO locate your
humidifier on an inside wall near an electrical outlet.
The humidifier should be at least 4 inches (10 cm) away
from the wall for best results.
5. NEVER place humidifier in an area where it is
accessible to children. NEVER use humidifier in a closed
room, particularly where a child may be sleeping,
resting, or playing (a closed room may result in

been dropped or damaged in any manner. Return
appliance to manufacturer for examination, electrical
or mechanical adjustment, or repair.
10. Use appliance only for intended household use as
described in this manual. Any other use not
