HOW TO FILL
CAUTION: Before filling the tank with water, turn the power off and unplug the unit from the outlet.
NOTE: The water tank is not removable from the humidifier base.
1. Before filling, remove the tank cap and tank cover. Be sure the mist chimney is locked into the humidifier tank by pushing down and turning the mist chimney to the right, so the pointer is pointing to the lock symbol.
CAUTION: Never fill the water reservoir with water before the mist chimney is locked.
2. Fill the tank with clean, cool (not cold) water until the water level reaches the MAX fill ring.
CAUTION: Never add essential oils or any other additives to the water tank. Even a few drops will damage the unit.
3. Replace the tank cover and tank cap.
POWER ON/OFF BUTTON & OUT OF WATER INDICATOR
Plug unit into a 120-volt AC electrical outlet. Press the power button to turn unit on. When the humidifier is out of water, the LED will glow red.
NOTE: If the mist chimney is not completely locked, the water reservoir will overfill causing the out of water LED to glow red. Should this happen, follow steps 1-3 in the cleaning the transducer/ultrasonic membrane instructions.
MIST OUTPUT
Mist adjusts from the lowest output (1) to the highest output (2). To increase the mist output, press the mist output button. The corresponding mist level will be lit above the button. Continue to press the mist output button to cycle through the mist output settings.
MIST TEMPERATURE SETTING
To change the mist temperature from cool to warm mist, press the mist temperature button. Red will be illuminated above the button. To change the mist temperature from warm to cool mist, press the mist temperature button again. The LED will turn off.
NOTE: Once warm mist is selected, it will take approximately 20 minutes to heat up before the mist becomes warm.

NOTE: Always be sure the humidifier has a full tank of water prior to using the timer setting.
AUTO-OFF
When the water in the tank is almost gone, the humidifying function will power off and the out of water indicator will illuminate red, indicating it is time to refill the tank.
NOTE: It is normal to have a small amount of water in the tank after use.
CLEAN TRANSDUCER/ULTRASONIC MEMBRANE
The clean LED will illuminate red after 60 hours of use, indicating it is time to clean the transducer/ ultrasonic membrane. See cleaning instructions in the Cleaning and Care section. Press and hold the clean transducer/ultrasonic membrane button for 3 seconds to reset the clean indicator.
HOW TO USE
ESSENTIAL OIL
Use your favorite essential oil to deliver aroma into the air.
NOTE: For use with the included HoMedics essential oil pads only.
NOTE: Do not leave a filled essential oil pad in the oil tray of the humidifier if it will be out of use for a long period of time.
ARE ESSENTIAL OILS SAFE TO USE AROUND PETS?
We should always exercise caution when using essential oils around our pets. Keep all essential oil and aromatherapy products (like diffusers) out of the reach of pets. Keep open bottles away from pets to avoid internal consumption. We do not recommend the topical use of essential oils on pets, as they have a strong sense of smell and cannot get rid of the oil if they don’t like it or it is disturbing them. When diffusing essential oils around pets, always diffuse in a well-ventilated area and leave an option for them to remove themselves from the space, such as leaving a door open. Every animal is different, so carefully observe how each animal responds when introducing an essential oil for the first time. If irritation occurs, discontinue the use of the essential oil. We recommend seeking medical attention if ingestion of essential oil occurs.
ADDING ESSENTIAL OILS
WARNING: Putting oil anywhere but the oil tray will damage the humidifier.
1. The oil tray is located on the back of the humidifier at the bottom of the humidifier base.
2. Push to open and remove the tray. Place 1 aroma pad (3 included) into the oil tray.
3. Add 5–7 drops of essential oil to the pad. You may use more or less depending on personal preference.
WARNING: Only place essential oil on the pad and NOT directly into the tray.
4. Place the oil tray back in its compartment and push to close. The scent will start automatically when the mist is turned on.
ABOUT WHITE DUST
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 buildup. If white dust still forms around the humidifier after a new cartridge has been installed, consider using distilled water.
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.
INSTALLATION INSTRUCTIONS
Demineralization Cartridge
- Remove demineralization cartridge from packaging and soak in water for 10 minutes.
- Remove the tank cap.
- Fill the tank with water as shown in the How to Fill section of this instruction book.
- Add the soaked demineralization cartridge to the tank.
- Replace the tank cap on the humidifier.
CLEANING AND CARE
CAUTION: Before cleaning the unit, turn power off and unplug unit from the outlet.
CLEANING THE TRANSDUCER/ULTRASONIC MEMBRANE
The transducer/ultrasonic membrane must be cleaned to remove water mineral deposits when the red LED is illuminated above the clean transducer/ultrasonic membrane button. Failure to do so may cause reduced or no mist output.
1. Remove the tank cap and tank cover and set aside.
2. Remove the mist chimney by pushing down and turning it to the left until the pointer is pointing to the unlock icon and pulling up.
3. Pour out any water remaining in the tank.
4. Clean the transducer/ultrasonic membrane with a 50/50 mix of white vinegar and water on a cotton swab. Wipe off with a damp cotton swab. NEVER touch the transducer/ ultrasonic membrane with your fingers; the natural oils in the skin can damage the surface. NEVER submerge the base in water or any other liquid.
5. Clean the water reservoir with a 50/50 mix of white vinegar and water on a cotton ball or clean, soft cloth as needed. Wipe off with a damp cotton ball or soft, clean, damp cloth.
6. After cleaning, reassemble the humidifier, fill with water, plug in, and turn on.
7. Press and hold the clean transducer/ultrasonic membrane button for 3 seconds, until the LED light above the button turns off.
TO CLEAN THE TANK
Remove the tank cap and tank cover from the humidifier.
Every day: Empty and rinse the inside of the tank before refilling.
Every week: To remove any scale or buildup, use a 50/50 mixture of white vinegar and lukewarm water to clean the inside of the tank.
TO CLEAN THE OIL TRAY
Open the oil tray and remove the pad. Essential oil pads should be changed when switching to a different scent. If continuing to use the same scent, set the oil pad aside for reuse. Wipe the inside of the oil tray with a soft cloth. Place the essential oil pad back in the tray and close.
NOTE: Leave the essential oil pad out of the oil tray when storing.
TO CLEAN THE SURFACE
Clean the surface of the unit with a soft, damp cloth.
STORAGE
Clean the surface of the unit with a soft, damp cloth. Clean the tank cap, tank, mist chimney, water reservoir, and the transducer/ultrasonic membrane with a 50/50 mixture of white vinegar and water. Be sure to rinse and let all parts dry completely before storing. Clean the oil tray with a soft, damp cloth.
After storing: Rinse the tank with water prior to operating.
