There are children in the future suddenly feel that there is a need for clean water equipment, decoration of the new home in the future want to choose a clean water equipment, every day to buy water in the community water machine feels troublesome and unreliable... Faced with a large number of clean water equipment, how should we choose a suitable one for our own use? Today let Li Jing, a folk enthusiast of clean water equipment, tell us about her experience in choosing clean water equipment.

As a housewife, Li Jing initially discussed those matters about clean water equipment at the beginning of the renovation of her new home. "In recent years, various brands of water dispensers, water purifiers, water softeners and other industrial water equipment products have emerged, and various water purifiers use different filtering methods and filtering materials. I have discussed the detailed principles of various clean water equipment.

Li Jing pointed out that the water dispenser should be the earliest clean water equipment we touch. It is a kind of equipment that can raise or lower the temperature of barreled pure water (or mineral water) and make it convenient for everyone to drink. However, there are many shortcomings in water dispensers. The first question is the lack of water entertainment temperature. The highest temperature of drinking water machine is 95 C for most of the great food water equipment, and 90 C for recreation. The temperature of tea sterilization is not good. Secondly, the water in the drinking water machine is reheated repeatedly to form the so-called "thousand boiling water", which makes the accumulation of trace elements and minerals in the water constitute insoluble particles. Thirdly, it is difficult to clean the inner part of the drinking water machine, which simply collects scales and bacteria.

Pure water machine is a kind of pure water machine which can be directly drinkable by human beings without adding any compound after filtering the raw water through the method of reverse osmosis which was prevalent in the world at that time. Pure water produced by pure water machine is related to fresh, cleaner and safer barreled water. It has a wide range of uses: it can be drinked raw or boiled. In this respect, the most outstanding feature is that the kettle or the thermos bottle will no longer scale. Pure water produced by pure water machine is used for cooking, more clean and more delicious. This kind of water bath can eradicate impurities on the skin, moisturize the skin and play a role in natural beauty. In addition, it can be used as water for small household appliances such as humidifiers, steam irons, beauty machines and so on. There will never be a boring white powder, which can be used in conjunction with the ice maker to make ice cubes glittering and clear without any peculiar odor. However, the use of water purifier will also bring some doubts, because minerals and trace elements in the water will be filtered out at the same time in the process of water filtration, so it is not recommended to drink water filtered by water purifier for a long time.

Softeners are the primary solution to the scaling problem caused by hard water. Therefore, in the United States, where water quality is relatively hard, domestic softeners have been appropriately widely used. Natural water can be divided into hard water and soft water. Water rich in calcium and magnesium ions (inorganic minerals) is called hard water, and soft water is called soft water. The soft and hard water is related to the taste. Hard water is refreshing. Most mineral water has high hardness, which makes people feel fresh and delicious. Soft water appears insipid and tasteless. Soft water is now widely accepted by European countries, as well as the United States, Japan, South Korea and other countries, because of the removal of calcium, magnesium and other hardness ions in the existing water quality. After a bath, even with a thick moisturizer, the skin will still feel itchy and itchy, and the water you drink will have an indescribable weird smell; the clothes you wash will always be stiff... Original, these are the mistakes of hard water.

The primary treatment object of household water purifier is turbidity, chroma, organic matter in tap water, which generally consists of three parts: pre-filtration, adsorption and fine filtration. In the meantime, absorb and approve fine filtration is the primary method to remove organic matter and chroma in water. The objective working conditions directly affect the water quality of the water purifier. Li Jing pointed out that what she knew was to remove the impurities that should be removed, but to preserve the minerals and trace elements that should be preserved. After careful comparison, according to his own practice, Li Jing chose a water purifier after all.

To buy products, consider from three aspects

The following considerations should be taken into account when purchasing a clean water equipment with useful aspirations:

First, we should choose famous brand products.

It is necessary for manufacturers producing clean water equipment to obtain some cleaning licenses from superior cleaning supervision, and after technical supervision, it is concluded that these licenses are in line with the National Standards for Daily Drinking Water Quality.

2. Choosing and purchasing products with high performance-price ratio.

1. Clean water equipment structure is different, and the function of clean water is also different. Generally speaking, the structure of the first-stage filter water purifier is simple, mainly activated carbon, its filtering ability is limited, it can only be used for rough filtration, and the filtered water is best heated and boiled for drinking. The first-grade filters are mostly classified as low-grade clear aquatic products, with quotations ranging from more than ten yuan to 150 yuan per unit.

2. Multistage filtration equipment. The water purifier has two stages of coarse filtration and a group of fine filtration, and the hollow fiber filter element is mostly used for fine filtration. The filtered water can be directly drinkable. Multistage filter water purifier belongs to middle-grade aquatic products. Each price is between 300 yuan and 500 yuan, which can be accepted by the working class. At that time, families used it more.

3. Clean water effect of reverse osmosis water purifier is the most ambition. It has three-stage pre-filtration, one-stage reverse osmosis membrane fine filtration and one-stage post-filtration. The filtered water has no bacteria, viruses, heavy metals, pesticides, organic matter, minerals and peculiar odor. It is pure water and can be drinked without heating. This kind of reverse osmosis water purifier belongs to high-grade clear water products, and each price is between 3000 yuan and 5000 yuan.

3. Purchase according to water quality.

1. Water hardness is different in different areas. In the northern and southern limestone areas of China, the content of calcium and magnesium ions in water is relatively high, which is high hardness water quality. Simple scaling, high-grade filters with ion exchange resin filters should be purchased.

2. Urban tap water with chlorine, heavy color and odor, and high organic content in water can be purchased as household water cleaner with more activated carbon load. Activated carbon has a strong adsorption on residual chlorine and peculiar odor in water, and has a significant removal effect on organic matter.

3. For the purification of turbid tap water in urban and rural areas, household water purifiers with two functions of coarse filtration and fine filtration should be selected. To save energy at home, open water can be directly drinkable without heating, you should choose reverse osmosis water purifier.
