Cleaning and Care
CAUTION:
Before cleaning the unit, turn power off and unplug unit from the outlet.
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. (Fig. 7) 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
Pour a 50/50 mixture of vinegar and water on the surface of
the ultrasonic membrane, 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. (Fig. 8)
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
To Clean the Surface
Clean the surface of the unit with a clean damp soft cloth as
often as needed. (Fig. 9)

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 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.
Installation Instructions
1. Remove demineralization cartridge from packaging and let it soak
in water for 10 minutes.
