Why is a home water purifier a hoax?

The reason why it's a hoax is that there are many manufacturers of poor water purifiers who have seen the development prospect of China's water treatment market, but use inferior materials for production and processing, or play with the concept of what's clean water, pure water, direct drinking water, pure water, activated water, oxidized water, ecological water, etc. What's more, some businesses add some minerals manually Quality, it becomes mineral water, adding some oxygen molecules, it becomes oxygen rich water, adding a little sodium bicarbonate, it becomes weak alkaline water It's not a scam. What is it?

But a fact that cannot be ignored is that there is a need for water purifiers. So to speak, the water that families in developed countries in Europe and America drink is also purified. Then look at foreign fast food, KFC and McDonald's. the water they use is also purified. Therefore, from the perspective of necessity, the household water purifier is not a fraud to some extent.

Is the water source polluted all over the country? How much is it polluted? These data are available on the Internet. Even if they are not, you can have a look at the water treatment equipment of the water company in your city, the aging of the water supply pipeline, including the water supply pipeline in your community Which link can ensure that our drinking water reaches the standard?

What kind of water treatment do we need? Xiaobian wants to say that there are only three kinds of water in the market: soft water, clean water, pure water, and other water, such as activated water, oxygen rich water, direct drinking water, ecological water, etc., are all conceptual hype.

The water softened by the water softener is to remove the substances that cause scaling in the water and let the domestic water to calcify. There is no common feeling of hardness, such as fluffy after washing clothes and towels, and smooth skin after bathing. This is the function of soft water, but soft water is not recommended to drink. The water purified by the water purifier, in short, is to purify some harmful substances, some heavy metals and bacteria. The purpose of such water is to drink and cook.

The water filtered by the pure water machine can be understood as the removal of all impurities, the absence of heavy metals and bacteria. What comes out is pure water, or even distilled water. The difference between the pure water machine and the purified water machine is that each liter of pure water produced by the pure water machine wastes about 3 liters of left and right (different brands) of waste water, which is a bit of a waste of resources. The disadvantage of pure water is that the minerals beneficial to human body are also filtered out, which is generally not recommended for cooking.
