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.

THIS PRODUCT IS EQUIPPED
WITH A POLARIZED PLUG (a
plug having one blade wider than
the other). This plug will fit into the
power outlet only one way. If the
plug does not fit fully into the 
outlet, reverse the plug. If it still does

not fit, contact qualified personnel to install the proper outlet.

DO NOT DEFEAT THE SAFETY PURPOSE OF THIS
POLARIZED PLUG IN ANY WAY.

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 Bionaire

®

Cool Mist humidifier draws dry air through

the rear air intake grill area. This air is then passed through
2 moisture–laden wick filters which retains the minerals and
deposits. 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%.

BEFORE USE (PRE-OPERATING INSTRUCTIONS)

1. Be sure the humidifier is switched to OFF and the unit

is disconnected from the electrical outlet.

2. Take housing off base and remove foam packing

beneath the housing. Place housing back on base.

3. 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

FILTER CLEANING INSTRUCTIONS

1. The water tray should be cleaned

when you clean the filter. The
water tray is a convenient way to
carry the filter to prevent dripping.

2. Mix 1 gallon warm tap water with

antibacterial liquid dish washing
soap.

3. Fully submerge filter in soap 

solution for 15-20 minutes.

4. Dunk filter in soap solution several times then gently

press to release the soapy water.  Be sure not to wring,

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 variables such as:

✔ 

Air exchange in the room where the humidifier is placed.

✔ 

Room construction of the room where the humidifier is 
placed.

✔ 

Temperature of the room where the humidifier is placed.

✔ 

Humidity levels in the room where the humidifier is 
placed.

✔ 

Movement of occupants and the opening and closing of 
doors in the room where the humidifier is placed.

✔ 

Home furnishings in the room where the humidifier 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 humidity 
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.
