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 automatically oscillates 120°. The oscillating head can also be stopped at any point in the oscillation cycle to target the mist in a specific direction.
Warm or Cool Mist Option
Choose either warm or cool mist for customized comfort.
Auto Shut Off Protection
When the tank is empty the unit will shut off automatically.
Advanced Multi-Protection
The humidifier shuts off automatically if the water tank is removed OR unit is overloaded.
Ultrasonic Nebulizer
The humidifier utilizes special spray techniques and the ultrasonic nebulizer is easy to clean for lifetime use.

Cool & Warm Mist Ultrasonic Humidifier
How To Use
CAUTION: This appliance has a polarized plug (one blade wider than the other). To reduce the risk of shock, this plug is intended to fit only one way in a polarized outlet. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician.
DO NOT attempt to defeat this safety feature. To do so could result in an electric shock hazard.
Power Knob
Plug unit in to a 120 volt AC electrical outlet. Push the POWER ON/OFF ( 
) button to turn unit on.
ATTENTION: When the water in the tank is almost empty, the power will shut off to indicate to the user to refill water.
Mist Increase and Decrease
There are 7 different levels of mist output from Lowest to Highest. To increase the mist output, press the MIST INCREASE ( 
) button until the desired mist output is reached. When the maximum mist output has been reached, the indicator ring light will blink once and will blink each time the MIST INCREASE button is pressed. To decrease mist, press the MIST DECREASE ( 
) button until the mist has decreased to the output level desired. When the minimum mist output level has been reached, the indicator ring light will blink once and will blink each time the MIST DECREASE button is pressed. (Fig.2)
Warm and Cool Mist Control
The humidifier is equipped with the option to select warm or cool mist. Each time the unit is turned on it will start producing cool mist. The Warm/Cool mist indicator ring will glow with a blue light. To select Warm Mist, press the WARM/COOL MIST button. When warm mist is selected, the mist indicator ring will change from blue to red and warm mist will start being produced. To return to cool mist, press the WARM/COOL MIST button again. The mist indicator ring will change from red to blue. (Fig.2)
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. (Fig.2)
NOTE: The oscillation feature will not operate if the humidifying function is not operating. Oscillation feature will only work when mist is being produced.
How To Fill
- To release the tank from the unit, place your fingers with your palm facing upward into the recess in the tank handle. Press the tank release button with your thumb.
- Pull the water tank away from the humidifier base by the handle and remove the water tank from the base by lifting it up and away.
- Turn the tank upside down – remove the tank cap by turning it counter-clockwise.
- Fill the water tank with clean, cool (not cold) tap water. We recommend using distilled water if you live in a hard water area.
- Replace the tank cap by turning clockwise until tight.
- Install the tank back on the base of the unit. Make sure the tank is firmly seated in the base.
- Press the tank handle into the base of the humidifier. You will know that the tank is locked into place when the locking mechanism clicks and the tank release button is in a raised position.
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
- Remove demineralization cartridge from packaging and let it soak in water for 10 minutes.
- To release the tank from the unit, place your fingers with your palm facing upward into the recess in the tank handle. Press the tank release button with your thumb. (Fig.3)
- Place 1 demineralization cartridge down onto post and into the matching slot in the humidifier base. (Fig.11)
- Place the tank back on the base. (Fig.8)
- Press the tank handle into the base of the humidifier. You will know that the tank is locked into place when the locking mechanism clicks and the tank release button is in a raised position. (Fig.9)
Cleaning and Care
CAUTION: Before cleaning the unit, turn power off and unplug unit from the outlet.
Tank Cleaning
Remove the tank from the base by placing your fingers with your palm facing upward into the recess in the tank handle. Press the tank release button with your thumb and lift the water tank out and away.
Unscrew the tank cap; wipe the tank with a soft cloth then wash it with clean water.
Suggestion: Clean the water tank once every two to three weeks, depending on your water conditions.
Ultrasonic Nebulizer Cleaning
Put small amount of mild dish soap on the surface of the ultrasonic nebulizer, then pour in some water and soak for 5 minutes. Brush clean with soft bristle brush (not included) and rinse.
