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 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 # UHE-HDC4, go back to the retailer
(where you purchased your humidifier), or visit (US) www.homedics.com, (CAN) www.homedics.ca
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 let it soak in water for 10 minutes.
2. Remove the tank from humidifier base and turn it over.
3. Unscrew the tank cap by turning the cap counter-clockwise.
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 into the tank.
6. Replace the tank cap by turning clockwise.
7. Place the tank back on the base.

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, rinse and dry the tank, tank cap and water
reservoir before refilling.
Every Week: To remove any scale or build up, use a 50/50
mixture of white vinegar and lukewarm water to clean the inside

Every Day: Empty, rinse and dry the ultrasonic membrane and
the reservoir before refilling.

on the surface of the ultrasonic membrane and in the reservoir,
then soak for five minutes. Brush clean with a soft-bristle brush
(not included) and rinse.
NEVER touch the ultrasonic membrane with your fingers as the
natural oils in skin can damage the membrane.

TO CLEAN THE SURFACE
Clean the surface of the unit with a clean damp soft cloth as
often as needed.
Before Storing: Clean the Tank, Tank Cap, Reservoir and the
Ultrasonic Membrane with a 50/50 mixture of white vinegar and
