Unique Features and Specifications
Ultrasonic Technology
This humidifier uses ultrasonic high frequency technology to convert the water into
1-5 million super particles that are dispersed into the air evenly. These particles then
combine with the ions generated by the humidifier to moisten the air.
Oscillating Head
The humidifier features a motorized nozzle that oscillates 120°. The oscillating head
can also be stopped at any point in the oscillation cycle to target the mist in a
specific direction.
Night Light
A useful night light feature is included for your convenience.
Auto Shut Off Protection
When the tank is empty the unit will shut off automatically.
Overheat Protection
This humidifier is equipped with a non-resettable fuse in case of overheating. If
the non-resettable fuse has been activated, operation cannot be resumed. The
fuse will need to be replaced by an authorized service personnel.
Ultrasonic Nebulizer
The humidifier utilizes special spray techniques and the ultrasonic nebulizer is easy to
clean for lifetime use.

Oscillation
When the humidifier is producing mist, press the OSCILLATION ON/OFF ( ) button
to turn on the motorized oscillation feature. The nozzle at the top of the unit will
oscillate in a 120° range from side to side. To target the nozzle and mist in a fixed
direction, press the OSCILLATION ON/OFF ( ) button when the nozzle is at the
desired position and the nozzle will stop and direct mist to the desired area only.

About White Dust
Use of high-mineral content hard water will cause a white mineral residue to
accumulate on room surfaces near the humidifier. The mineral residue is commonly
called "white dust". The higher the mineral content (the harder your water is), the
greater the potential for white dust. The white dust is not caused by a defect in the
humidifier, but is due only to minerals suspended in the water.
Demineralization Cartridge
The HoMedics demineralization cartridge will help reduce the potential for white
dust, a deposit of minerals left behind from using hard water in your humidifier.
The cartridge should be replaced every 30-40 fillings. The cartridge may need to
be replaced more often when very hard water is used. When the cartridge needs
to be changed, white dust will form around the humidifier. If white residue still
forms around the humidifier after a new cartridge has been inserted, please make
sure that the water you are using is untreated. If you live in a hard water area,
we recommend the use of distilled water for better results from the
humidifier. Do not use with water softeners.
Installing Instructions
1. Remove demineralization cartridge from packaging and let it soak in water
for 10 minutes.
2. Remove the oscillation nozzle. To remove the nozzle, turn the ring on the
bottom of the nozzle to the left until the locator icons on the head, ring and
base all line up and are aligned with the UNLOCK position. Lift up to remove
the nozzle and set aside. (Fig.4)
3. Raise the flip-up handle on the water tank and remove the tank from the
humidifier base by lifting it up and away. (Fig.5)
4. Place 1 demineralization cartridge down onto post and into the
matching slot in the humidifier base. (Fig.12)
