Many people want to install a water purifier at home. Is it really useful to install a water purifier? With the increasing safety risks of water quality in various parts of China. For example, in the southern region, the water quality is generally hard, and it is easy to cause stone disease and other factors affecting the health of the human body; in the northern region, the heavy metals are generally exceeding the standard, which poses a hazard to human liver, gallbladder, and kidney. The most important function of the water purifier is to improve the tap water, to drink, to replace the bottled water, cheaper and more sanitary. Can we specifically see what the role of the water purifier is?
Is it useful to use a water purifier at home? Method / step Household purifiers mainly filter out impurities in the water. If you use them, you will see that the filter element filters out some small particles, some are impurities in our water supply pipe, and a purifier with disinfection function, disinfecting the water again if you It is best to use a purifier in a small city.
Is it useful to use a water purifier at home? 2 After the tap water is boiled, it is still impossible to remove scale, heavy metals, volatile substances, and bacterial carcasses. After the tap water is disinfected by chlorine gas, it can kill viruses and bacteria, but it can’t remove scale, heavy metals, volatile substances, etc., and the corpses of viruses and bacteria still exist, and after chlorine poisoning, the chlorine will be present in the water. Tap water will choose to boil and drink again, but boil can only deal with bacteria Issue (problem), can not deal with sediment, rust, scale, heavy metals, volatile substances and bacterial bodies and other Issues, so you need to install Water device to solve these problems

Does the water purifier really work? Finally no longer have to be misled by others!
Some homes can improve people’s happiness index, such as our usual, water purifiers, humidifiers, and some kitchen convenient supplies. Before my husband used the water in the house to cook rice, I felt that the taste was wrong. Later I bought it. A water purifier, I think this is a function of the heart, the tap water itself has been treated, and later he let me taste the difference between the boiled rice out of the water purifier and the rice directly cooked in tap water, I know It turned out to be useful. My husband worked as a small scientist at the institute. He told us why.
In fact, not all the water quality is very good. Hearing that the water in some places, although processed by the treatment plant, still has a little rust or chlorine smell, it is because of the treatment. Still not enough, if we use a water purifier, we can effectively eliminate these.
Water is essential for our survival. We usually cook rice for cooking and drink water for tea. In this respect, we must not underestimate it. Even if the water quality is good, we should pay attention to it. It is best to add a household water purifier. Do the second treatment, so you can feel at ease.
Some people may worry that the water purifier is just a scorpion. The things inside are all furnishings. Let us use it with confidence. Actually, it is not. The surface of the water purifier can’t be seen now, but the internal structure is enough to achieve the purpose of purifying water. , pp cotton, activated carbon, reverse osmosis, etc., layer filtration.
What we need to pay attention to is that it is ok to change the filter element frequently, because this kind of thing also has a long service life. The time is long, the filtering effect does not exist, it is a display, usually it is 2-3 months to replace the filter element, the problem is Solve it, the most important thing, if you want to drink water, you must boil it in use.

In addition to changing the filter, the water purifier can be left alone?
The maintenance of the water purifier should firstly change the filter element at regular intervals, otherwise… The filtration effect is weakened and the water quality is deteriorated. The adsorption capacity of the filter element is saturated. The plugging of the filter element will not only reduce the amount of water, but also reduce the filtration effect. If the water in this state continues to drink, it will affect the health of the body. Filter element is damaged step by step, filter life is shortened The water purifier is generally filtered step by step by a multi-stage filter. If the primary filter element is blocked, large particles of impurities such as sediment and rust in the water will directly enter the second-stage filter element, so that the filter element that is not responsible for filtering impurities is overloaded, resulting in early retirement. You only need to lose two or more filter cartridges because of the bad habit of “changing the filter cartridge from time to time”. Water purifier life is also affected The loss of the filter element can be more than the damage of the filter element: just because the filter element is the core component of the water purifier, it is as if the heart and lung function of the person is not strong enough, the operation of the whole machine will become dull, such a machine is very fast. Will also “end to sleep.”
For those who are often on a business trip or returning from a trip, the household water purifiers in the home will always be ruthlessly into the “cold palace”, from one or two weeks to more than a year and a half. However, the water purifier has not been operated for a long time, and if it is not treated properly, it may cause secondary pollution to the water quality. Therefore, before using, be sure to use the following correct method to “activate” again~ 1. When using again, rinse the water purifier first. The home water purifier is deactivated for a long time. When it is used again, it needs to be rinsed first: it is not used for about 3 days, and it is washed for 3-5 minutes; if it is more than 10 days, it needs to be washed for 15 minutes; if it is more than one month or even longer Use, the inside of the filter may breed bacteria and mold, in order to avoid secondary pollution, it is recommended to thoroughly clean the filter once.
2, after a long time to stop water, you must first discharge If water is stopped for a long time, after the water supply is restored, a large amount of sediment, rust and other substances will be deposited in the water pipe. At this time, the water purifier will be used again. It is necessary to open the sewage outlet and remove the sediment and rust inside to avoid water purification. The device is clogged, does not have water or water, has odor, and even shortens the life of the filter. 3. If necessary, backwashing If the water purifier is not used for more than one month, the inside of the filter element of the water purifier will breed bacteria. It is recommended to thoroughly clean the filter element when using it again. If the water quality still appears to be poor, it is recommended to backwash the water purifier. After the water purifier is backwashed, the contaminants in the water will be discharged from the drain outlet with direct flushing. 4, half a year, it is recommended to replace the filter If it is not used for 3-6 months or longer, consider replacing the filter element. Because it will not be used for a long time, some filter elements will lose the filtering function, such as ultrafiltration membrane drying and pore size shrinkage. Moreover, the ultrafiltration membrane cannot be recovered, which will cause the water in the water purifier to become smaller or even fail. If this happens, the filter cartridge needs to be replaced. (You can clean the filter element first, then test the water purification effect, and then decide whether you need to replace the filter element according to the purification effect)
5. If you need to go out, you can close the tap water inlet valve in advance. If you are going to travel or do not use the water purifier for a long time, be sure to close the inlet valve of tap water and do a good job of power failure and water cut. In order to avoid the uninformed situation, because the water pressure is too large, the faucet will fall off and cause a water increase event, resulting in unnecessary losses. In addition, the water purifier that is not used for a long time needs to drain the water in the machine. At the same time, the outdoor water purifier needs to turn off the ball valve and drain the water from the whole machine and the filter bottle to avoid freezing the machine due to the cold weather.
In addition to the normal life cycle of the water purifier, if the machine can be durable, it is still inseparable from daily maintenance: 1. When using the machine for the first time, the filter element inside the water purifier must be flushed to wash off the protective liquid in the filter element. The specific operation is as follows: open the tap water inlet ball valve, tap water tap, purify the tap, and then frequently switch the tap (for example, off for 3 seconds, 8 seconds) to form a pulsed impact for 15 minutes until the water is clear and free of foam. 2, need to be cleaned regularly, the product will be used for a certain period of time, there will be impurities accumulation, filter plugging and so on. When the water output is less than half of the original, it means that the water purifier filter has been blocked more seriously, and the filter can be flushed (many models have a flush button on the control panel, long press for three seconds). 3, do not expose to the sun and cold, it is important to emphasize that the water purifier is not suitable for outdoor installation, because whether it is higher in the summer outdoor temperature, it is easy to age under the sun exposure, or the temperature in the winter is too low, the internal waterway will freeze, Damage to the water purifier. And, no matter which kind of water treatment machine, it may breed blue algae under high temperature and sunlight. Therefore, the water purifier is suitable for installation in a cool place indoors, not too close to the heat source. 4. The water pressure of the tap water should be stable. If the water pressure suddenly becomes too small, the water hammer phenomenon will occur. If the pressure is too large, it will easily damage the internal components of the water purifier. Therefore, the water purifier can be pre-installed before the water purifier is installed. Valves, in the case of going out or not using the water purifier for a short time, you need to close the inlet valve to protect the water purifier from water pressure, which can extend the life of the water purifier.
The above are some precautions for the use of water purifiers~ I hope everyone must keep in mind! As the saying goes: “Water does not rot, the “live water” that flows continuously can maintain the vitality of life~

Bacteria, lead, pesticides, can your brand’s big water purifier filter?
In recent years, “blood lead events” caused by water pollution have frequently occurred, and “lead removal” has become an essential function of water purifiers. The American academic journal Environmental and Health Outlook has stated that the corrosion aging of lead-containing pipes and the use of lead-cast faucets will increase the lead content in the water.
According to Liu Xinwei, lead in water may also come from the discharge of industrial wastewater. Long-term drinking of lead exceeding the standard will cause lead to accumulate in the human body and produce certain toxicity.
“Boiled water can only have the effect of sterilization, but it has almost no effect on other harmful substances such as lead.” Zhao Feihong introduced.
Two products with lead content exceeding 5μg/L in the filtered water – Germany BST end water purifier Woda-Pure 120 and the US blue floating imported LPE-KC-UF type water purifier (type II), respectively Drop 2 levels.
Both products have poor results in addition to pesticide residues
In the case of pesticide abuse, excess pesticides may be adsorbed by the soil or washed into the groundwater and surface water with precipitation, especially in some rural areas, and there may be excessive pesticide residues.
This time, we also tested the pesticide filtration capacity of the water purifier.
From the product description point of view, the inspection of the water purifier has not promoted the effect of removing pesticides. However, in the pursuit of better quality and safer products, the two products of Germany’s BST and the US Bluefair, which have poor effect on filtering pesticides, have dropped 2 levels.
Filter nickel and nitrate? The effect is not obvious
In addition to bacteria, lead, pesticide residues and other “frequent customers”, there are also nickel and nitrate in the water.
“The nickel in the water may be derived from the discharge of nickel-containing wastewater; the improper use of fertilizer will produce nitrate, some of which will enter the water through the ecological cycle.” Liu Xinwei analysis.
Yu Lanxuan, former director of the Nursing Department of the Affiliated Hospital of Qingdao University Medical College, said that a small number of people will develop an allergic reaction to nickel, causing physical discomfort; and some nitrates can be converted into carcinogenic nitrite during metabolism.
Zhao Feihong introduced that the pure water machine using RO reverse osmosis membrane technology has a certain filtering effect on nickel and nitrate, but the ordinary water purifier does not have obvious filtering effect on these two substances.
