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 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.
- The oil tray is located on the left side of the humidifier at the bottom of the humidifier base.
- Push to open and remove the tray. Place 1 aroma pad (3 included) into the oil tray.
- 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. - 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 A 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 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
- Remove the demineralization cartridge from packaging and let it soak in water for 10 minutes.
- Remove the tank from the humidifier base and turn it over.
- Unscrew the tank cap by turning counterclockwise.
- Fill the tank with water as shown in the How to Fill section of the instructions included with your humidifier.
- Add the soaked demineralization cartridge into the tank.
- Replace the tank cap by turning clockwise.
- Turn the tank over and place the tank back on the base.
Demineralization Cartridge
To purchase new Demineralization Cartridges, Model # UHE-HDC4, go back to the retailer (where you purchased your humidifier), or visit www.homedics.com (US), www.homedics.ca (CAN).
CLEANING AND CARE
CLEANING THE TRANSDUCER/ULTRASONIC MEMBRANE
The transducer/ultrasonic membrane must be cleaned to remove water mineral deposits when the red LED above the clean transducer/ultrasonic membrane button is illuminated. Failure to do so may cause reduced or no mist output.
- Remove the water tank from the humidifier base and set aside.
- Pour out any remaining water inside the water reservoir.
- 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. Press and hold the clean button for 3 seconds until the clean light turns off.
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.
TO CLEAN THE TANK
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.
Every day: Empty and rinse the tank and tank cap 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 essential oil scent. If continuing to use the same scent, set the essential oil pad aside for reuse. Wipe down 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. Before storing: Clean the tank, reservoir, tank cap, 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 cloth.
After storing: Rinse the tank with water before operating.
