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.

1. The oil tray is located on the
back of the humidifier, at the
bottom of the humidifier base.

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
in the tray.

To purchase genuine HoMedics Replacement Essential Oil Pads, Model # UHE-PAD1, go to your retailer where you purchased your HoMedics
TotalComfort Ultrasonic Humidifier, or visit www.homedics.com (US), www.homedics.ca (CAN).

To purchase genuine HoMedics Essential Oils, go to your retailer where you purchased your HoMedics TotalComfort Ultrasonic Humidifier, or
visit www.homedics.com (US), www.homedics.ca (CAN).

2. Push to open and remove the tray. Place 1 aroma pad
(3 included) into the oil 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

1. Remove demineralization cartridge from packaging and soak in water for 10 minutes.

2. Remove the tank from humidifier base and turn over.

3. Unscrew the tank cap by turning counterclockwise.

4. Fill the tank with water as shown in the How to Fill section of the instructions included with
your humidifier.

5. Add the soaked demineralization cartridge to the tank.

6. Replace the tank cap by turning clockwise.

7. 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

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 above the clean transducer/ultrasonic membrane button is illuminated. Failure to do so may cause
reduced or no mist output.

Transducer/Ultrasonic Membrane

1. Remove the water tank and extension nozzle
from the humidifier base and set aside. Pour
out any excess water remaining inside the water
reservoir.

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: Pour out remaining water inside the water reservoir.
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 inside the tank.

2. 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 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 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 clean, damp, soft 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 water tank with water before operating.
