Description

boiling water filter

technical field

The invention relates to a filter, in particular to a boiling water filter.

Background technique

Water is the source of life. Nutrients penetrate the whole body through water, and waste is excreted through water. Water is the most basic substance of life. Drinking water reasonably can not only strengthen the body, refresh the mind, and increase intelligence, but also prevent aging, prolong life, beautify, and detoxify.

Boiled and naturally cooled boiled water has the functions of promoting metabolism, transporting nutrients, cleaning internal organs, diuresis and laxative, and enhancing the body's immunity. The boiled water kills the pathogenic bacteria during the boiling process, and retains calcium, magnesium, phosphorus and other macro and trace elements that are beneficial to the human body. At the same time, it has a greater affinity with the water molecules in the biological cells in the body, and it is easy to enter the cells through the cell membrane. So boiled water is the best choice for people. However, scale products such as calcium carbonate and magnesium carbonate are produced due to the combination of anions and cations during the heating process of water, so scale problems inevitably exist in boiled water. But everyone only pays attention to the filtration of cold water, ignoring the scale problem in boiled water, so how to solve the scale problem in boiled water is the subject of our painstaking research.
