Nowadays, electric kettles have entered thousands of households. This is the most ordinary small appliance, affordable and convenient to use. However, in the past few years, I found that drinking water with some kind of electric kettle is often caused by manganese poisoning , which will lead to memory loss or induce cancer over time. Therefore, when choosing an electric kettle, you should be cautious and avoid buying inferior and harmful products. What harm will drinking water from an electric kettle bring to you every day? The water burned in an electric kettle needs to be treated dialectically. Choose an electric kettle produced by a regular manufacturer. The drinking water is sterile and harmless, and even if you drink it every day, there is no harm. If you choose a inferior electric kettle or water source that is contaminated, it will bring safety hazards and easily cause abdominal pain, diarrhea and infection. Focus on talking about ordinary steel electric kettles with poor materials. Some unscrupulous merchants may use high-manganese steel or high-manganese steel scraps as the material for electric kettles. After a little polishing, they will sell them to consumers. There is a situation where heavy metals exceed the standard, low safety factor, and pollute drinking water. 
How to choose an electric kettle?
. Use 304 stainless steel material
When buying an electric kettle, see if it is made of 304 stainless steel. It is a food-grade material and has high safety. Although there is no difference between food-grade and non-food-grade stainless steel, the latter is harmful to the body, and it contains too many heavy metal ions, which are easy to precipitate when in a high-temperature environment, strong alkaline or strong acidic environment, causing heavy metal poisoning over time. If the electric kettle is marked as "for food contact" and is made of stainless steel , then it is preferred.
. Buy
in regular channels. Purchase electric kettles in regular shopping malls or large supermarkets. Choose products produced by manufacturers with good reputation. The quality is guaranteed, and relatively high safety factor and reassurance. When buying an electric kettle, you think about asking for an invoice so that you can protect your rights in a timely manner if there is a problem.
How to boil water healthily?
. Control the water volume
A considerable number of elderly people add too much water to the electric kettle in order to save electricity, which is not advisable. When the water boils to 100℃, it will boil, and the excess water will overflow, which is very likely to be scalded by hot water, especially for children with poor safety awareness; and the overflowing water may enter the electrical socket, resulting in leakage and threatening the safety of family members' lives. Therefore, when boiling water, the electric kettle should not be filled very well. The maximum amount of water should be about 2 to 3 cm away from the spout.
. Turn off the power when connecting water
Can't connect water when turning on the power, because the electric kettle continues to heat up at this time. This behavior can shorten its service life, and it will also bring safety hazards and even the risk of electric shock. In addition, when using an electric kettle to connect water or boil water, make sure the bottom is dry and wipe dry with a dry cloth to prevent electricity.
3. Clean scale frequently
Use an electric kettle for a long time. Scale is easily generated at the bottom and around it, which not only affects the water quality, but also shortens the life of the electric kettle, but also easily wastes electricity. Therefore, clean the scale every 1 to 2 weeks, put baking soda , vinegar or grapefruit peel in an electric kettle to boil to achieve the cleaning effect.
