Warm mist humidifiers do not spread fine mineral dust into the air that you breathe nor on your furniture, the way that other type humidifiers do. The mineral dust remains trapped in the humidifier hot water reservoir. Use of Mineral Absorption Pads will play a major role in capturing and removing minerals from hot water reservoir, and preventing a stubborn mineral buildup.

1. Before starting humidifier, place mineral absorption pad in the hot reservoir. After the humidifier has been operating, the water will become HOT, and CAUTION should be exercised when handling mineral absorption pad. It is best to allow humidifier water to cool down, and to use tongs or long tweezers when handling pad.
2. The useful life of the mineral absorption pad will vary, depending on the mineral content of the water used. In areas of moderate mineral content water supply, the mineral absorption pad should be changed after approximately (3) weeks of continuous use. If the water is "Hard Water", the pad should be changed more frequently. The best way to tell when the should be changed is to examine it AFTER the water has cooled down, to see if it is still soft and pliable. When the pad is near the end of its life, it becomes stiff and hard and should be replaced with a new pad. Another sign to change pad is when scale begins to buildup on interior of hot water reservoir.
