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.
