Demineralization Cartridge (Model DC-102)

Your humidifier comes with a Demineralization Cartridge that removes minerals from the water. This prevents the precipitation of minerals ("white dust") that can occur in hard water areas. The Demineralization Cartridge is designed to last for about a month to two months of normal use; the effective time will vary depending on the mineral content of the water used. If you live in a hard water area, we recommend the use of distilled water for better results from the humidifier.

If you are using distilled water in the humidifier, you may find the Demineralization Cartridge unnecessary. And, if you choose, you may operate the humidifier without it.

About "White Dust":

Use of high-mineral-content 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.

Care and Cleaning

CAUTION: ALWAYS TURN OFF THE POWER SWITCH AND DISCONNECT THE POWER CORD FROM THE ELECTRICAL OUTLET BEFORE CLEANING.

Daily Maintenance:

1.Lift the Water Tank from the Base and empty all water from the reservoir. Remove the Tank Cap and drain any water from the Water Tank. Wipe it clean with a soft, damp cloth. Rinse the Water Tank with lukewarm water after each use.

2.DO NOT immerse the Base in water. Gently wipe the reservoir with a soft, clean, wet cloth.

3.DO NOT use detergent to clean any water-containing parts of the humidifier. Detergents and the film they leave behind can affect the output of the humidifier. DO NOT use abrasive cleansers or brushes.

4.DO NOT leave water in the Water Tank or reservoir when the unit is not in use as it may result in the buildup of mineral deposits and bacteria that can inhibit the output efficiency of the humidifier. Please note that if water remains in the Water Tank for more than a day or two, bacteria growth is possible.

Weekly Maintenance:

1.Thoroughly clean humidifier every week using a solution of bleach and water (one teaspoon of bleach in one gallon of water). Fill the Water Tank partially with this solution, let stand twenty (20) minutes, shaking vigorously every few minutes. Drain and rinse with clean water until the bleach smell is gone.

2.Wipe the reservoir with a soft cloth dampened in the solution. Rinse area thoroughly before proceeding.

3.If mineral deposits are evident around the Nebulizer, clean the surface with a soft, clean cloth and a small amount of undiluted white vinegar. If necessary for removal of mineral deposits, mix a solution of 50% white vinegar and 50% water and fill the Base with enough solution to cover the Nebulizer. Rinse out the reservoir and wipe clean. DO NOT touch Nebulizer with bare fingers as any fingerprints or other residue can affect mist output.

4.All surfaces should be thoroughly cleaned with water prior to reuse.
