How To Use

Power/Mist Knob
Plug unit into a 120 volt AC electrical outlet. Turn the POWER/MIST ( ) knob clockwise to turn the humidifier on.
ATTENTION : When the water in the tank is almost empty, the humidifying function will power off to indicate to the user to refill the tank.
Mist Adjustment Setting
Mist adjusts from MINIMUM ( ) mist to MAXIMUM ( ) mist. To increase the mist output, turn the POWER/MIST knob clockwise. To decrease mist output,  turn the POWER/MIST knob counter-clockwise.
Night Light
Press the NIGHT LIGHT ( ) button to turn on the night light. The surround around the POWER/MIST knob will glow softly.

SoundSpa
NOTE: The SoundSpa feature operates independently of the humidifier. It will continue to operate even if the humidifying function is not operating.
There are 4 soothing, rhythmic sounds included with the SoundSpa feature: Summer Night, Heartbeat, White Noise, and Lullaby.

  • To turn the SoundSpa on, turn the SOUND SPA POWER/ VOLUME ( ) knob clockwise. The default sound, Summer Night, will begin to play.
  • To adjust the volume, turn the SOUND SPA POWER/ VOLUME ( ) knob clockwise to increase the volume and counter-clockwise to decrease the volume.
  • Choose any one of the 4 sounds by pressing the appropriate sound button.
  • To turn the SoundSpa off, turn the SOUND SPA POWER/ VOLUME ( ) knob counter-clockwise until a click is heard and the sound stops.

Sleep Mode
This humidifier includes a Sleep Mode feature. The Sleep Mode will allow the SoundSpa to operate for 30 minutes, then shut off automatically.

  • To turn the Sleep Mode function on, first press the desired Sound Selection button.
  • Once the Sound Selection has been made, press the SLEEP ( ) button. This will begin the 30-minute sleep cycle. When the 30 minutes cycle is over, the SoundSpa will automatically stop producing sound and power off.
  • To power the SoundSpa back on for normal operation after the 30-minute SLEEP MODE cycle is over, turn the SOUND SPA POWER/VOLUME knob counterclockwise to the OFF position,  then back ON. When the SoundSpa is turned back on, the default SUMMER NIGHT sound will begin playing.
  • To return to normal operation once the Sleep Mode has been activated, and before it shuts off, simply press another Sound Selection button. The sleep mode will turn off, and the new sound selection will run continuously until either the SLEEP ( ) button is pressed, or the SoundSpa is powered off.

NOTE : The humidifier will continue to operate if it is functioning when the Sleep Mode automatically powers off the SoundSpa feature.

How to Fill

How to Fill

About White Dust:

The use of high mineral content hard water may cause a white mineral residue to accumulate on surfaces in the room near the humidifier. The mineral residue is  commonly called “white dust.” The higher the mineral content (or, the harder your water is), the greater the potential for white dust. The white dust is not caused by a defect in the humidifier. It is caused only by minerals suspended in the water.
How and Why To Use Demineralization Cartridges:
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 if you are using very hard water. Replace the cartridge when you notice an increase in white dust build-up. If white dust still forms around the humidifier after a new cartridge has been installed, consider using distilled water. To purchase new demineralization cartridges, model # HUM-HDDC4-6CTM, go back to the retailer (where you purchased your humidifier) or visit www.homedics.com
If you live in an area with hard water or use a water softener, we recommend using distilled water for better results from your humidifier. Never use water softening additives in your humidifier.

Installing Instructions

  1. Remove demineralization cartridge from packaging and let it soak in water for 10 minutes.
  2. Remove the tank from the humidifier base. (Fig. 3)
  3. Place the soaked demineralization cartridge into the matching slot in the humidifier base. (Fig. 9)
  4. Place the tank back on the base, making sure the tank is firmly seated. (Fig. 7)
    Note: Demineralization cartridge has no top or bottom. Either side can face upward.

Cleaning and Care

CAUTION: Before cleaning the unit, turn the power off and unplug the unit from the outlet.
Tank Cleaning
Remove the water tank from the humidifier base by lifting it from the main unit. Unscrew the tank cap and rinse inside the tank with clean water. To remove any scale or build-up, use a 50/50 mixture of vinegar and lukewarm water to clean the inside of the tank.
Suggestion : Clean the water tank once every two to three weeks, depending on your water conditions.
To Clean the Ultrasonic Membrane:
Put a small amount of mild dish soap on the surface of the ultrasonic membrane, then pour in some water and soak for 5 minutes. Brush clean with soft bristle brush (not included) and rinse. (Fig. 11)
Suggestion : Clean the membrane once every two to three weeks, depending on your water conditions.
NOTE : Never submerge the base in water or any liquid.
Surface Cleaning
Clean the surface of the unit with a clean damp soft cloth as often as needed. (Fig. 12)
