Cleaning and Care
CAUTION: Before cleaning the unit, turn power off and unplug unit from the outlet.
About White Dust
Use of high-mineral content hard water will cause a white mineral residue to
accumulate on room surfaces near the humidifier. The mineral residue is commonly
called "white dust". The higher the mineral content (the harder your water is), the
greater the potential for white dust. The white dust is not caused by a defect in the
humidifier, but is due only to minerals suspended in the water.
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 when very hard water is used. When the cartridge needs
to be changed, white dust will form around the humidifier. If white residue still
forms around the humidifier after a new cartridge has been inserted, please make
sure that the water you are using is untreated.
If you live in a hard water area,
we recommend the use of distilled water for better results from the
humidifier. Do not use with water softeners.
Installing Instructions
1. Remove demineralization cartridge from packaging and let it soak in water
for 10 minutes.
2. To release the tank from the unit, place your fingers with your palm facing
upward into the recess in the tank handle. Press the tank release button with
your thumb. (Fig.3)
3. Place 1 demineralization cartridge down onto post and into the
matching slot in the humidifier base. (Fig.11)
4. Place the tank back on the base. (Fig.8)
5. Press the tank handle into the base of the humidifier. You will know that the
tank is locked into place when the locking mechanism clicks and the tank
release button is in a raised position. (Fig.9)
Tank Cleaning
Remove the tank from the base by placing
your fingers with your palm facing upward into
the recess in the tank handle. Press the tank
release button with your thumb and lift the
water tank out and away.
Unscrew the tank cap; wipe the tank with a
soft cloth then wash it with clean water.
Suggestion: Clean the water tank once
every two to three weeks, depending on your
water conditions.
Ultrasonic Nebulizer Cleaning

surface of the ultrasonic nebulizer, then pour
in some water and soak for 5 minutes. Brush
clean with soft bristle brush (not included)
