Product classification of water purifier? Because water pollution will harm people's health, many families will install water purifiers, but there are many kinds of water purifiers on the market, and many people are very entangled when purchasing. Let's share the product classification of the water purifier and have a look.
Water purifier product classification 1 water purifier product classification
1, softening method
Refers to the removal or reduction of hardness (mainly calcium and magnesium ions in water) to a certain extent. In the process of water softening, it only softens the water, but it can't improve the water quality.
2, distillation method
Is to boil water, then collect steam, cool it and condense it into liquid. Distilled water is extremely safe drinking water, but there are some problems to be further discussed. Because distilled water does not contain minerals, this has also become the reason why opponents suggest that people's life expectancy is easy to age. In addition, distillation has high cost and energy consumption, and it can't remove volatile substances from water.
3. Boiling method
It refers to drinking tap water after boiling, which is an ancient and widely used method in China. Boiling water can kill bacteria, but some chemicals and heavy metals cannot be removed, even if their content is extremely low, so it is still unsafe to drink.
4. Magnetization method
It refers to the treatment of water by magnetic field effect, which is called magnetization treatment of water. The process of magnetization is that water passes through the magnet in the direction perpendicular to the magnetic field lines, that is, the process of magnetization is completed. The magnetization treatment of water in China is still in the initial stage of practice and research, and foreign water purifiers do not need magnetization function, because magnetized water does not belong to the category of pure water, but belongs to medical problems.
5. Mineralization method
It refers to adding mineral elements (such as calcium, zinc, strontium and other elements) beneficial to human body to water on the basis of purification. Commercially available water purifiers generally achieve the purpose of mineralization by adding medical stone to the water purifier, but the Ministry of Health has clearly pointed out that "wading products must not promote any health care function".
6, ozone, ultraviolet sterilization
These aspects can only be sterilized, and heavy metals and chemicals in water cannot be removed. After being killed, the bacteria remains in the water and becomes a pyrogen.
7, electrolytic method (electrolytic water machine)
Electrolysis is a further water treatment technology based on ordinary filtration and purification methods. Ordinary water purifiers only filter impurities through ultrafiltration membrane, remove residual chlorine from tap water through coconut shell carbon filtration, and remove heavy metals through KDF, thus producing direct drinking water. On this basis, the electrolytic method fully electrolyzes tap water that meets the direct drinking standard through the electrode plate to generate electrolytic water, which has the following characteristics:
1, pure and free of impurities
2, rich in minerals
3. Small molecular groups of water are easy to absorb and sweat.
4, rich in active hydrogen, effective anti-oxidation
5. Negative potential
6. Alkaline water
It not only satisfies people's pursuit of clean and safe drinking water, but also has considerable health care function. Scientists all over the world have confirmed that electrolyzed water can prevent and alleviate the symptoms of "three highs", prevent and repair sub-health posture, and has obvious auxiliary effect on chronic diseases such as ventilation and constipation. Long-term drinking can keep people healthy.
Product classification of water purifier II. Is the water purifier useful?
1. No matter in theory or in practice, we can't deny the function of water purifier in purifying water quality. But in the process of buying water purifiers, we always exaggerate the practicality of water purifiers to stimulate consumption.
2. Don't believe that the more filter elements, the better. The purification effect of water purifier is not directly related to the number of filter elements. Don't believe that the filter can be used forever. If you want to continue to use the water purifier, you must replace the filter element in time.
3. Don't believe in the function of water purifier except water purification. These are exaggerated false propaganda. The function of the water purifier is to purify water, and there is no other function. Don't believe that there is a free water purifier, and businesses will not be at a loss. As the saying goes, there is no profiteering, no business, don't fall into the trap because of greed. In short, understand the truth of these water purifiers, don't be fooled, choose high-quality brand water purifiers to ensure the purification effect.
Second, how to choose a water purifier
1, according to different types of water purifiers, water purifiers can be divided into ultrafiltration direct drinking machines, reverse osmosis direct drinking machines, water purifiers, water softeners, pipeline water purifiers and central water purifiers. If the water quality is not particularly good, you can choose a reverse osmosis water purifier that can be directly drunk; If the water quality is moderate, you can choose ultrafiltration water purifier. If the water quality is too hard to damage clothes, you can choose a water softener. What kind of effect should the water heater achieve and what kind of water purifier should it choose?
2. Looking at the price of the water purifier, the price may be difficult to control, because the price of water purification products on the market ranges from tens of yuan to tens of thousands of yuan. Of course, the purification effect is different. Therefore, before checking the price, be sure to confirm the required water purification equipment. If you choose a reverse osmosis direct drinking water purifier, the price should be between 3000 yuan and 4000 yuan. Of course, it may be more expensive or cheaper than this price. I personally suggest that when buying a water purifier, don't blindly choose the price or quality, but choose the local water quality and the purpose of purchase.
