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 # HUM-HDDC4-6CTM, 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.
1. Grasp tank handle and lift up from humidifier base.
2. Turn the tank upside down—remove the tank cap by
turning it counter-clockwise.
3. Fill the water tank with clean, cool (not cold) water. We
recommend using distilled water if you live in a hard
water area.
4. Replace the tank cap by turning clockwise until tight.
5. Install the tank back on the base of the unit. Make sure
the tank is firmly seated.
