HOW COOL MIST WORKS
Your Bionaire
®
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 unit is disconnected from the electrical
outlet and the power switch is in the OFF position.
2. Lift off the humidifier housing and the water tank (see

IMPORTANT:
If you do not plan to use your humidifier for two or more
days, make sure any residual water is drained from the
water tank, base and wick filter to prevent any algae or
bacteria growth in stagnant water.
NOTE:This humidifier holds about 1.4 gallons of water
between the tank and the base and will produce up to 3
gallons of moisture over a 24-hour period, depending on
the room humidity and temperature.
REPLACING THE FILTERS
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
humidifier by checking the Filter Check™ Indicator. When
the unit is off, the Filter Check™ Indicator will read in the
OFF position. After 60 minutes of use, Filter Check™
Indicator (refer to Figure 3 for close-up
of indicator) will move from the OFF
position and indicate your filter condition.
A brand new filter will register in the blue
section reading GOOD filter. After
frequent use of your humidifier, the
Filter Check™ Indicator will let you know
when the filter needs to be changed.
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 filter. 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. 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.
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.
4. Check the Filter Check™ Indicator to see if it is time to
see if it is time to replace the filter. Depending on your
water hardness, it may be necessary to change the
filter every 1-2 months.
5. Refill the water tank with fresh tap water, replace the
housing of the humidifier, and then the water tank. Plug
into the electrical outlet, and turn the power ON.
NOTE: Please be sure to wipe up any spilled cleaning
solution as it may damage furniture or floors.

FREQUENTLY ASKED QUESTIONS
QUESTION
• What are the variables that
affect run time?
• How do I remove film on
water tank?
• How can I extend the run
time?
ANSWER
☛ The estimated run time for this humidifier is based on
average room conditions. The actual run time of your
humidifier is dependent on numerous vari ables such
as:
1. Air exchange in the room where the humidifier is
placed.
2. Room construction where the humidifier is placed.
3. Temperature of the room where the humidifier is
placed.
4. Humidity levels in the room where the humidifer is
placed.
5. Movement of occupants and the opening and
closing of doors in the room where the humidifier is
placed.
6. Home furnishings in the room where the humidifer is
placed.
☛ See Daily Maintenance instructions. Regular cleaning
is recommended.
☛ Run your unit on the lowest setting.
☛ If your unit has electronics, set it to your desired humid
ity level.The unit will turn on and off, which will extend
the run time.
☛ Fill the tank all the way full, place it on the base, let
the water empty into the base until it stops bubbling,
then refill the tank full again. This ensures maximum
water capacity and will extend run time.
