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
(They look like blue “capsules” and are included in a separate bag)
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. 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.
5. Add 1 blue demineralization cartridge into the tank.
6. Replace the tank cap by turning clockwise.
7. Place the tank back on the base.

new one. Do not disconnect the wires.
5. Replace the UV holder, replace and tighten the screws.
