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.
