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 thehumidifier.Theroomalready 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
approvedextensioncord may beused.The electrical rating
ofthe extension cord must be equal to or greater than the
ratingofthe humidifier.Caremustbe taken toarrangethe
extensioncord sothat it willnot drapeover thecountertop
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%.

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.
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
oftenyou willneed to change your filter.
You will be able to monitor the life of the filter in your
humidifier 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 will move from
theOFFpositionandindicateyourfilter
condition. A brand new filter will
register in the blue section reading
GOODfilter.Afterfrequent use ofyour
humidifier, the FilterCheck®Indicator
willlet youknow whenthe filtersneed
tobe changed,(see Figure 2).
When the needle is in the light red (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.
