The tap water used in our life is disinfected and bleached by chlorine in the waterworks and then delivered to thousands of households. In order to ensure that tap water is not polluted by bacteria during transportation, tap water in water pipes usually contains some residual chlorine, which is harmful to human body after a large amount of chlorine is ingested, so tap water needs to be boiled before use.

However, boiling tap water does not mean that residual chlorine is completely removed. The chlorine removal function of the thermostatic kettle is to boil the water in the kettle, wait for a period of time, and evaporate harmful substances such as chlorine and trihalomethane in the water through boiling again, so as to obtain safe and healthy water.
