The UF model retains calcium, magnesium ions and trace elements in the water while filtering harmful substances. The calcium and magnesium ions in the water will be oxidized and reduced with the continuous increase of temperature, forming white crystals. this is an oxidation and reduction phenomenon, not impurities in the water. (This happens if boiled water is boiled with mineral water ).Personal advice, generally do not make tea, it is best not to boil the water, warm to the body temperature is close.
