Thermostatic kettle needs defluorination every time. For the sake of safety, it is suggested to boil water in a thermostatic kettle before defluorination.

At present, chlorine is a common disinfectant for tap water. Chlorine was used in tap water before purification, but chlorine may remain in tap water after use. If the baby drinks chlorine-containing tap water, it will have an impact on the normal establishment of its intestinal flora, and it is also easy to directly harm the baby's brain development. If the chlorine removal function of the thermostatic kettle is not turned on, it is suggested that the thermostatic kettle should not be turned off immediately after boiling, but let it boil for a while, so that the chlorine in tap water can be removed. If you cook for a period of time, remember not to turn on the chlorine removal function, otherwise it is easy to produce trihalomethane, a carcinogen.
