The invisible harmful substances in drinking water are eroding your body!

The invisible harmful substances in drinking water are eroding your body!

Water is the source of life
We have to drink water every day,
So what are the harmful substances commonly found in water?
What harm do these substances pose to our health?
Let’s take a look at the hazards of common substances in the water today.

The main harmful substances in drinking water
Visible to the naked eye: red worms, sediment, suspended matter, particulate matter, colloids. (excluding calcium magnesium carbonate precipitate)
Invisible substances: microorganisms (bacteria, viruses), heavy metals, lead, mercury, chromium (hexavalent chromium) exist in an ionic state.
Residual chlorine: the cause of cancer. (trihalomethanes, and carbon tetrachloride)
Organic Compounds: The World Health Organization has detected 2,221 chemical substances in tap water, of which more than 300 have been identified as carcinogens and suspected carcinogens. These include fertilizers, pesticide residues, hormones, antibiotic residues, and nitrites.

The harm of unqualified water to the human body
Cause kidney burden, reduce kidney function, lead to kidney failure, severe cases have to change kidneys.
The quality of the raw materials of the cells is degraded and the immune function is lowered.
The body’s sensitivity to environmental changes is reduced, and the ability to be protected from harm is reduced.

How to achieve healthy drinking water
Please install the household water purifier
1, the relationship between water and stomach
When heavy metals in the water enter the stomach, it will destroy the intestinal mucosa and kill some of the beneficial bacteria (digestive enzymes), leading to gastrointestinal diseases, such as: “gastritis, stomach ulcers, gastric perforation, colitis, and other chronic diseases.” Said water pollution is one of the important reasons for the formation of gastrointestinal diseases.
2, the relationship between water and kidney
The kidney is made up of several glomeruli, and the body needs about 5 kg of water per day. The polluted water enters the kidneys of the human body, and the excessive concentration of pollutants in the water causes the excretion burden of the kidneys to increase, and at the same time increases the incidence of stone disease.
3, the relationship between water and liver
One of the functions of the liver is to process and filter blood. The pollution of water quality will promote the quality of blood, and form hepatitis, cirrhosis and even liver disease. Polluted water molecules enter the heart through the blood circulation, and are transported to thousands of blood vessels. Therefore, the quality of water pollution is one of the main causes of liver disease.
4, the relationship between water and blood vessels
The length of human blood vessels is added together. It can be around the earth for two and a half weeks. The lumen of the blood vessels is very narrow. The heavy metals in the blood combined with the oil to form a thrombus factor. As the blood flows, it blocks in the stenosis, causing cerebral thrombosis, myocardial infarction, etc. Vascular disease. Therefore, the quality of water pollution is also one of the causes of cardiovascular and cerebrovascular diseases.
5. The relationship between water and cancer
The biggest characteristic of cancer cells is anaerobic. During the process of decomposition, a large amount of oxygen is absorbed, which causes the organic matter in the water to exceed the standard. The human environment hypoxic cancer cells can survive and reproduce. Therefore, water pollution is also one of the important causes of high cancer diseases.

Is water purifier really useful?

Is water purifier really useful?

The role of the water purifier is to treat tap water in depth.

There are four main types of purification methods that are common. The latter three methods of cleaning cover 100% of the best price water purifier, so the principle of the water purifier can be explained.

01 boil

Yes, boil.

Boiling is an effective and economical way to purify tap water.

Boiling has three functions:

1, anti-virus: eliminate bacteria and viruses.

2. Reduce disinfection by-products: residual chlorine.

3. Reduce the hardness of water: scale.

Boiling does not solve two problems:

1. Heavy metals, organic pollutants in tap water, and other unconfirmed other pollutants.

2, domestic water, such as the residual chlorine in the bathwater will be absorbed by the body through the nose and skin.

Therefore, the role of the water purifier is to solve the problem that boiling cannot be solved.

02 adsorption

Activated carbon is widely used in water purifiers for two reasons:

1. Low cost and high efficiency, mainly used to treat residual chlorine.
2. It can be used in the “membrane filtration” water purifier to protect the “film” and prolong the “membrane” life.

Activated carbon is a porous substance, and the inner surface composed of micropores accounts for more than 95% of the total area, and excessive voids and large pores account for only 5%. Activated carbon relies on microporous adsorption to remove organic matter.

Activated carbon is a mature technology. In the 1950s, the US Environmental Protection Agency confirmed that activated carbon has a certain adsorption capacity for trihalomethanes (described in detail below), but the cycle is short.

The three criteria can help you judge the pros and cons of activated carbon:

1. The longer the activated carbon filter layer, the better. The longer the contact time of water with activated carbon, the better the adsorption effect.
2. Activated carbon fiber is better than granular carbon and powdered carbon. The former has more micropores, and the adsorption amount and adsorption speed are better.
3. Shell carbon is better than coal and wood charcoal. The common shell carbon is coconut shell charcoal.

Compared with activated carbon, KDF is more expensive but has the function of removing heavy metals.

KDF is a copper-zinc alloy, which is divided into KDF55 (50% copper and 50% zinc), KDF85 (85% copper and 15% zinc), and KDF55 is usually used in the water purifier.

03 ion exchange


Ion exchange is generally used in water softeners to treat “scale”.

Explain “scale” first.

The scale is calcium bicarbonate produced by calcium and magnesium ions after water is boiled.

The calcium and magnesium ion concentration is related to the hardness of the water. The calculation method is as follows:

Total hardness (calculated as CaCO3) = (calcium mg/Lx2.5) + (magnesium mg/Lx4.1)

The human body has certain adaptability to the hardness of the water. The hardness of water can withstand more than 500mg/L, so WHO does not propose a health-based guideline value for hardness in drinking water. China’s drinking water standard is set at 450mg / L, but even in northern China, the hardness is not so high.

However, scaling after boiling water will affect the quality of life, the eyes will feel uncomfortable, washing clothes will not be so easy to wash, and the service life of water heaters and hot water bottles will be shortened.

Water softeners generally reduce the hardness of water by ion exchange resins, and common sodium ions are used to exchange calcium and magnesium ions.

There are two disadvantages to this exchange method: 1. The sodium content in the softened water is not well controlled. 2. High cost.

In China, where the hardness of water is generally not high, and drinking hot water (water will generate scale and physically reduce the hardness of water), the water softener actually has a very narrow living space.

In addition, the installation of a reverse osmosis RO and nanofiltration purification water purifier, there is no need to install a water softener.

04 Membrane treatment

Membrane processing is actually the easiest to understand, but from the back-end consultation, consumers are the most confused about this piece.

Two reasons are caused: 1. There is no unified national standard, and the business has a single word; 2. The merchant itself is confused. The latter is even more terrible.

What is the role of the water purifier?

What is the role of the water purifier?

In today’s life, there will still be people asking this question, which makes some home water purifiers feel helpless.

In fact, with the improvement of living standards, water purifiers are not new, and many people have this equipment in their homes. The development of water purifiers is related to our deteriorating environment and to our growing material life requirements. The role of the water purifier is obvious and the price is not expensive. For most families, it is a necessity.

The main function of the water purifier is to improve the tap water, to drink directly, to replace the bottled water, to be healthier and more sanitary. We can specifically look at the role and advantages of the household water purifier.

Cleaner than boiled water
Although the boiled water is boiled, some bacteria have died, but the alum, sediment, rust, high-temperature bacteria, chlorine, heavy metals and other harmful substances in the water are boiled and cannot be removed.

Save peace of mind, save trouble, and save money
Many people use bottled water instead of tap water, but the bottled water on the market is mixed and the quality is worrying. In addition, bottled water must be consumed within a certain period of time. Exceeding the time limit, bacterial microbes are abundantly produced and endanger human health. Many manufacturers still use fake and shoddy “recycling bins” to give water “secondary pollution”.

Effectively remove harmful substances
It is understood that the water purifier is a purely physical filtration method, which can effectively remove harmful substances such as bacteria, residual chlorine, heavy metals, scale (calcium and magnesium, etc.), volatile substances, rust, sediment, etc. Drinking is, therefore, the ideal drinking water treatment solution for the family.

Concerns about water quality should start with “drinking water”, and a group of water partners aiming to improve the quality of drinking water were born in the late 1980s. The emergence of tap water, bottled water, and water dispensers have indeed improved the human drinking water environment to a certain extent, but its inevitable secondary pollution and poisonous barrel incidents have been exposed one after another. People began to pin their hopes on water purifiers. The more families are concerned about and installing water purifiers.

Quality life guarantee
After the tap water is disinfected by chlorine gas, it can kill viruses and bacteria, but it cannot remove scale, heavy metals, volatile substances, and the like. The most effective way is to install a water purifier in the household water terminal, deep purification in the water terminal, and effectively separate and remove various pollutants such as bacteria, residual chlorine, heavy metals, volatile substances, rust, sediment, etc. Impurities and harmful substances in water can fully solve the secondary pollution problem of tap water and protect your home water.

The water purifier is a display? After reading you, you are silent!

The water purifier is a display? After reading you, you are silent!

The importance of water to human health, I am afraid everyone can say one or two. However, our daily tap water has experienced too many cruel flaws in the processing, rust, heavy metals, pesticides, dyes… and various viruses, bacteria and other microorganisms, even after boiling, simple sterilization Chloride and heavy metals in the water will not decrease. Therefore, it is very important to filter the water and drink it.

However, the filter kettle is slow to filter, the RO water purifier is bulky, the installation is troublesome, the price is high, the faucet water purifier is more friendly, the purification is quick, the price is close to the people, the volume is still small… except that the purification effect is not known, everything looks They are perfect. In order to answer the doubts and confusion in everyone’s mind, today we will test the Olansi intelligent monitoring faucet water purifier.

The packaging looks very textured. The water purifier looks like a camera lens. At first glance, it is super technical, and the middle LED lights are very cool.

The fittings for all kinds of faucets are all in line, 3 internal thread adapters and 1 external thread adapter, which can match the various thread taps that are common in the market. There is also a separate monitor cover that can be attached to the adapter when the filter is removed.

Remove the bubbler of the faucet and gently rotate it up. It is more labor-saving than installing the bulb, it does not occupy the place, it is light and easy to carry, and it can be brought together on a business trip.
Of course, it is definitely not only because it is convenient, after all, there are many products of the same type on the market. I value its water purification technology and its own monitoring module. The two functions are two of its biggest highlights. It is said that after the filtration, the detection module of the palm of the hand can accurately detect various data in the water, and score the water quality, so that you have a number before you drink.

Its filter element is also full of black technology. The activated carbon fiber + ion exchange fiber selected by Olansi composite filter has large micropore content, narrow pore size distribution and twice the surface area of ​​ordinary filter element, which means stronger filtration capacity. I will know when I test it.

Turn on the faucet and in the original water state, the TOC, TDS, turbidity and temperature data in the water are detected in a few seconds, and the four-color LED lamp is used to indicate the quality of the water. Turn the switch to the side and turn on the clean water. The tap water comes out of the faucet and is filtered through the Olansi composite filter. It is clean and healthy water, and the LED light turns green instantly. This purification effect is obvious~

Raw water, clean water status LED light display

And these detailed water quality data are uploaded to the mobile app, and the water quality is intelligently scored by the AI ​​big data algorithm. You can completely see the filtering effect and the quality of the water according to the monitoring results.

Raw water, water purification APP data comparison

The turbidity and temperature data of water is very simple and clear.
The TOC and TDS sound like an inscrutable look.
Don’t worry, Xiaobian will come to you for science.

TOC refers to the total organic carbon content in water, which is a key indicator of the degree of organic pollution in water. Popular things are pesticide residues, biopharmaceutical residues, antibiotics, fertilizers, petrochemicals and other organic pollutants.

TDS is the total dissolved solids in water. Minerals, soluble salts, ionic organics, heavy metal ions, and calcium and magnesium ions are counted among them. It can also be regarded as one of the reference indicators of the degree of water pollution, but it can not really reflect the quality of the reaction water.

Because a cup of water containing a small amount of pesticide (or disinfectant, pesticide, etc.), compared with a cup of mineral water, TDS may be very small, but the TOC value will change significantly.

An experiment can be a straightforward explanation of the relationship between TOC and TDS.

The first group is the data of pure disinfection water, and the second group is the test data of disinfection water and tap water in a ratio of 1:1. It is found that the turbidity of water is obviously increased, while the TOC is straight down 68.1. %, while the TDS change is relatively small, only down 4.3%.

The purification effect is good, the slow water is also a nostalgic, after all, everyone’s time is very valuable 哒~Olansi intelligent monitoring faucet water purifier in the water purification state, the water is very fast, the water is also quite large, filled with 500ml of mineral water bottles Less than 10 seconds, there is no difference in the amount of water from the faucet, and there is no noise.

Filled with mineral water

Many households who have used household water purifiers have a problem. How often do you replace the filter? We all know that the water purifier works by the filter element. The traditional water purifier can’t monitor the specific purification of the water quality. The use of the filter element is naturally unknown. If you want to judge whether you want to change the filter, you have to open the machine to see its use, so that time and effort can not be avoided.

At this point, Olansi intelligent monitoring faucet water purifier is more humane and scientific, not only can monitor water quality in real time, APP will dynamically analyze the use of filter elements, intelligently remind the core change, let you replace the filter element in time, no Will cause secondary pollution.

What should I do if the water in the water purifier becomes smaller and does not produce water?

What should I do if the water in the water purifier becomes smaller and does not produce water?

“Xiao’ an, my family’s water purifier has suddenly become smaller in water production. Taking a glass of water is several times slower than when I just bought it. What is going on?”
“My water purifier suddenly didn’t have water this morning. For a time, I didn’t even know what water to use for even the children.”
“Why is the water in the water purifier released, suddenly stopped? After a while, shut yourself down?”
I don’t know if you have encountered a similar situation. If you have one, you should listen carefully! Next, Xiao An explained the reasons and solutions for the “water purifier water flow is small, no water”:

Check if the power supply and pipeline are connected properly.
When the water purifier is working, it needs to be connected to the power supply. When the power is off or the power is off, the machine will not work normally. Therefore, if you find that the machine does not have water, first check if the power is on. The second is to check whether the water pipe is smooth and whether the water inlet ball valve of the tap water is open.
Filter plug or service life expires
The filter element is the core component of the water purifier and bears the important responsibility of intercepting impurities and pollutants. However, the filter element also has a service life. Because each filter element has limited interception capability, if it is not replaced on time, the filter element will be clogged and the water purifier will not be able to discharge water normally.
Therefore, be sure to replace the water purifier filter on time to keep the water quality safe and healthy!
If the household water purifier in the home has a flushing function, it can be opened periodically, and the filter element is simply flushed, which is beneficial to the maintenance of the water purifier and prolongs the service life of the filter element.

Long-term water stop, first sewage treatment
If the tap water is stopped for a long time, after the water supply is restored, the water purifier will be used immediately if the sewage is not discharged first. A large amount of sediment, rust and other substances deposited in the water pipe will directly enter the water purifier, causing the filter element to clog and the machine not to discharge water. Or the effluent smells, affecting the normal use of the water purifier.
Therefore, after stopping the water, the water purifier should be turned off, the tap water is turned on to clean the sand in the water pipe, and then the water purifier is turned on.

Water protection mechanism triggers water cuts
After a long period of water production, the water purifier will actively evoke the self-protection mechanism of the machine, which will also cause the machine to suddenly stop making water.
This kind of “water protection” of the machine is to avoid internal damage caused by the long-term operation of the machine, and secondly to avoid long-term water production caused by forgetting to shut off the water, resulting in unnecessary waste of water resources.
In general, a large-fluid water purifier will trigger a water-making protection mechanism when the water is produced for about 1 hour. The small-flux or water purifier with a filter tank is about 5 hours.
When this happens, simply turn off the water purifier and unplug the power supply. After the “return blood” is completed, plug in the power and restart.
The tap water pressure is abnormal or the temperature is too low
If there is an abnormality in the water pressure at home, it will also cause the water quantity of the water purifier to become smaller. Because the ultrafiltration membrane and RO membrane of the water purifier have very small pore sizes, certain water pressure is required during the filtration process. When the tap water pressure is too small, the filter speed of the filter element will naturally slow down.
In general, the tap water pressure at 0.3 MPa is normal. You can check if other faucets in your home are normal. If the water flow is reduced, you only need to wait for the water pressure to recover, and the water purifier will return to normal.
In another case, in the winter or when the temperature is relatively low, the decrease in water temperature will cause the viscosity of the water to increase, causing the flow of the water to slow down, and the water production of the water purifier will decrease. This is a normal phenomenon. It can be recovered after the temperature rises.

Of course, if all of the above reasons are ruled out, it is not clear why the water suddenly appears to be out of water. It may be that the machine or component has failed. In this case, Xiaoan advises you to make an appointment with professional after-sales service personnel in time to check and repair!
Finally, you need to add another sentence. Don’t forget to carry out regular maintenance and filter replacement during the daily use of the water purifier. This is really important!

The water purifier is also afraid of cold? Winter antifreeze measures are learned!

The water purifier is also afraid of cold? Winter antifreeze measures are learned!

The optimal operating temperature of the water purifier:
Applicable water temperature 5 ° C -38 ° C
Ambient temperature 4°C-40°C
How to prevent freezing of the whole machine
Winter water purifiers are strictly prohibited from being placed outdoors.
If it has been installed outdoors, it is necessary to close the inlet ball valve, drain the water from the household water purifier, and transfer it to the room. If it cannot be transferred, it must have anti-freezing measures, and it should be wrapped with cloth and other materials for heat preservation. If there is no anti-freezing measures in winter, the filter bottles and membrane shells may be cracked.
The water purifier must be stopped at temperatures below 0 °C.
Since the volume of water will expand during the solidification process, if it freezes, it will directly cause the water purifier pipeline, filter drum, filter membrane shell, etc. to burst, resulting in machine damage and water leakage.
It is recommended to turn off the water purifier during the winter night.
In winter nights, the temperature is lower than in the daytime, and the water is less, the water flow in the pipeline is weakened, and the water is easily frozen. For this reason, it is recommended to close the sluice or water purifier at night to minimize the pressure on the machine caused by the water pressure. It is best to empty the water remaining in the water purifier to prevent freezing at night and low temperatures.
Especially for new homes, families that have not yet stayed in, it is necessary to close the water purifier and drain the remaining water in the machine.
What should I do if the machine freezes?
Suspend use first, and then observe the leak after natural thawing.
In case the water purifier has already frozen, the machine must be placed in a room above 8 °C (do not bump), and it can be used for 48 hours after it is thawed. During this period, the mechanism water should not be forced to open. Check whether there is water leakage after starting the machine. If there is any water leakage, please re-tighten the parts or contact the after-sales service.
Treatment after water stop
Close the inlet valve, put the clean sand and re-enable after passing the water.
Due to the low temperature in winter, the tap water pipe is prone to burst. If the tap water supply pipe is cracked or stopped, please turn off the water inlet valve of the water purifier. After the water supply is restored, it is necessary to ensure that the impurities such as sediment in the tap water are cleaned, and then the water purifier inlet valve is opened to avoid excessive impurities in the tap water, resulting in a decrease in the flow rate of the produced water or a blockage of the filter element.
When going out for a long time or when not using it for a long time, you should first close the water inlet ball valve, drain the water in the water purifier, and then cut off the power supply of the machine to prevent the water hammer from colliding and causing water leakage.
a phenomenon that is prone to occur in winter
1, the water production decreased
The lower the temperature, the greater the decrease in water production. Since the viscosity of water is affected by temperature, the water production of reverse osmosis membrane will decrease. Usually, the water temperature of the reverse osmosis membrane drops by 3% for every 1 °C decrease in water temperature. About 50% of the summer water production.
2. Increased wastewater
As the water production is reduced, the flow rate of the wastewater will increase accordingly, and the wastewater ratio will increase. This is a normal phenomenon. After the temperature rises, the wastewater will decrease and the water production flow rate will increase.

When the water purifier appears as follows:
1) Leakage of pipes or related components
2) Machine parts are disabled
3) Other abnormal phenomena or malfunctions

In addition to changing the filter, the water purifier can be left alone?

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~

9 reasons why you need a home water purifier

9 reasons why you need a home water purifier

2 How much water do we need per day?
The Chinese Dietary Guidelines state that healthy adults need about 2,500 ml of water a day. Adults living and exercising in mild climates are advised to drink at least 1200 ml per day, about 6 cups. If the amount of activity is large and sweating is more, increase the amount of drinking water and replenish water in time.

3 The healthy and good water that the human body can drink for a long time should have the following requirements:

4 What kind of water can we choose?

Linlin’s various kinds of water are dazzling, but they are not healthy and good for long-term drinking.

Pure water is purified by distillation, reverse osmosis and other technologies to remove raw materials. While removing harmful substances, it also removes almost all trace elements and minerals beneficial to the human body, so it is not suitable for long-term drinking.

Mineral water Most of the trace elements and minerals in mineral water should be said to be needed by the human body. However, studies have shown that not all types and amounts of trace elements and minerals contained in mineral water are suitable for all people, so it is not suitable for long-term drinking.

Beverages “Bai Boshui has no taste, or drink it.” Many children have cola and fruity drinks that don’t leave their hands every day. Drinking water with drinks is tantamount to spending money to buy problems. This does not help the body to replenish water, but also reduces appetite, affecting digestion and absorption.

Bottled water Bucket containing bottled water will be recycled and reused over a long period of time, which can easily cause fungal infections. The hygiene conditions of those manufacturers who are not regular are more difficult to guarantee.

Bottled water is easy to carry, open and drink, and bottled water is favored by more and more consumers. However, the PET bottles used in bottled water often contain substances that may cause chronic poisoning in the human body, especially when the bottle is in a high-temperature environment (if someone likes to have a bottle of water in the car), or does not drink it in time after opening. Harmful substances can seep into the water, and long-term drinking will endanger health.

5 The current pollution situation of water sources is more severe

The “State of the Environment Bulletin 2013” shows that 9.0% of the country’s top ten water systems are inferior, and nearly 60% of the national groundwater is not up to standard, and wastewater discharge is 69.54 billion tons…

River 9.0% water is inferior V
In 2013, China’s top ten water sources continued to suffer from various types of pollution.
The Yangtze River, the Yellow River, the Pearl River, the Songhua River, the Huaihe River, the Haihe River, the Liaohe River, the Zhejiang-Zhejiang River, the Northwest Rivers and the Southwest Rivers are the top ten river basins within the geographical range of China. The Ministry of Environmental Protection’s “2013 China Environmental Status Bulletin” shows that in the top ten basins, the IV~V category is 19.3%, while the proportion of the inferior V water quality section is 9.0%. The water quality of the top ten water systems is not optimistic.
Surface water is divided into five categories according to function: high, low: I, II, III, IV, V; the poor V water is the water whose pollution level has exceeded V, which means the pollution is the most serious.

Nearly 60% of groundwater is not up to standard
If the surface water system is polluted, can the groundwater escape?
The authoritative data of the Ministry of Environmental Protection shows that the pollution of groundwater is more worrying than the pollution of surface rivers. In 2013, groundwater quality monitoring was carried out in 198 prefecture-level administrative regions across the country. The total number of monitoring points was 4,778, including 800 national monitoring points. According to the “Groundwater Quality Standards” (GB/T14848-93), the comprehensive monitoring results show that the water quality is excellent level of monitoring points only 10.4% of all monitoring points; while the water quality is poorly monitored points accounted for 43.9%; the water quality is very poor The level of monitoring points accounted for 15.7%. That is to say, in the municipal-level administrative districts where groundwater quality monitoring is carried out, nearly 60% of the groundwater is not up to standard. Groundwater pollution is generally slow, difficult to find and difficult to manage. Once the groundwater is contaminated, it will take more than a decade or even decades to restore the water quality even if it is completely eliminated.

Annual wastewater discharge of 69.54 billion tons
Water pollution is so serious that excessive pollutant emissions are the main culprit.
In 2013, the total discharge of wastewater in the country was 69.54 billion tons, and the total discharge of chemical oxygen demand was 23.527 million tons. That is to say, if calculated according to the population of 1.3 billion, each person will face nearly 53 tons of wastewater discharge. These wastewater discharges come mainly from industrial sources, sources of life, and agricultural sources. Industrial pollution is the most important source of pollution for surface water.

6 water treatment technology of waterworks needs to be improved

Water from the water source must be treated by the waterworks before entering the home. Generally speaking, urban drinking water is mainly based on conventional water treatment technology, and surface water source adopts a coagulation-precipitation-filtration-disinfection water treatment process, and groundwater source is directly disinfected after being cleaned without purification process. The conventional treatment process is mainly aimed at removing turbidity, color, and microorganisms in water, and it is difficult to completely solve the problems of organic pollution, algae pollution, heavy metals such as lead and mercury which are prominent in current urban water sources.

At present, most urban water plants in China use liquid chlorine disinfection, and the action of chlorine with chlorine in the subsequent disinfection process will produce carcinogens such as organic halogenated hydrocarbons and various harmful by-products. It can be seen that the clean water treatment process needs to be improved, the pollutants cannot be effectively removed during the purification process, and even new pollutants may be introduced, which threatens the safety of urban drinking water.

7 water supply pipe network aging leads to secondary pollution

The urban water supply network system is a huge and complex project. Water from the water plant to the user needs to be transported over long distances. The residence time in the pipe network sometimes lasts for several days, and the pipe network has a great influence on the water quality. At present, the water supply network of the city, especially the old city, is generally corrosive and aging due to its long service life. The pipe network with a service life of more than 50 years accounts for 6% of the total. In recent years, the leakage of the pipe network has generally increased.

At present, the urban drinking water transportation system is mainly based on the transmission of the string network. Due to factors such as the material of the pipe material, the age of the pipe network, and the nature of the disinfectant itself, the water quality will have some changes during the water delivery process, accounting for 42.4% of the total national water supply. The survey results of cities show that the turbidity, chroma, and iron indicators have different degrees of deterioration compared with the factory water. The turbidity of the factory water is 1.3 degrees, and the pipe network water is increased to 1.6 degrees; Increased from 5.2 degrees to 6.7 degrees; iron increased from 0.09 mg/L to 0.11 mg/L.

8 Is your faucet qualified?

In addition to pipe network equipment, the last hidden danger of drinking water safety is hidden in the last ring of tap water. In order to reduce the cost of electroplating, some enterprises do not have good treatment of the surface such as rust removal before the lead-containing faucet is electroplated, resulting in poor surface corrosion resistance. Under normal circumstances, the quality of the electroplated faucet will not cause pollution, mainly because the surface of the electroplated coating will be oxidized quickly when it comes into contact with air, resulting in a protective film, but the use of unqualified faucets, water can lead The protective film falls off and invades the water, causing the precipitation of lead elements in the water nozzle, and the “overnight water” lead metal content retained in the faucet nozzle is higher. In addition, some companies now use copper processing to reduce costs, the lead content in the faucet is high, and the possibility of lead precipitation during use is greater.

9 Hazards of pathogenic microorganisms and pollutants in water to human health:

Therefore, the purchase of household water purifiers as a barrier to the safety of household drinking water is an effective way to control the risk of drinking water. At present, the penetration rate of household water purifiers in China is only 2%, and the penetration rate in developed countries has reached 70%1. At the time of purchase, it is recommended to consider the filter technology of the water purifier first, which affects whether the filtered water produced by the filter can be consumed for a long time, meets the requirements of healthy and good water, whether it is water-saving and environmentally friendly; , smart, security, brand reputation and other aspects of performance, in line with these requirements, the big brand home water purifier can be assured of choice.

Blessed are the “difficulties of choice” for home improvement water purifiers.

Blessed are the “difficulties of choice” for home improvement water purifiers.

Most of the water used is related to drinking water, such as daily cleaning of fruits and vegetables, soup, cooking and so on.

This has led many people to change the water quality of their drinking water by installing water purification equipment in the kitchen. As a result, the water purifier has become a good helper to promote the health of daily drinking water and has also been favored by many families. And this time we came to experience a reverse osmosis water purifier from the Olansi brand.

Advantages of reverse osmosis water purification

Most people have water dispensers at home, and they still rely on bottled water for daily tea and water. But in the kitchen, we need drinking water for daily cooking, or tap water, especially for families with soup habits. It is also unrealistic to rely on bottled water for all drinking water.

Thus, the emergence of reverse osmosis water purifiers changed this situation. The high-precision filtration of tap water through the reverse osmosis water purifier allows you to use pure drinking water directly in the kitchen, which is convenient for life. The reverse osmosis water purifier can filter out clean pure water because it has a built-in RO reverse osmosis filter and a filter element with front and rear. This is also a distinct advantage of the reverse osmosis water purifier. Especially in the case of poor water quality in the home, the choice of installing reverse osmosis water in the kitchen has a very significant improvement in water quality.


This time I will experience the Olansi water purifier. As for why it has a title of “big eyes”, then you will know.

Open the box, take out all the installation accessories, you can see that the accessories are very complete, the materials and workmanship of the accessories also give a fairly solid feeling.

The reverse osmosis water purifier needs to be connected to the power supply. The power supply of this machine has a fixed bayonet on the upper and lower sides, which can be stuck according to the actual installation.

The filter element is the top priority of the water purifier, and the Olansi water purifier uses a multi-stage composite filter design. The three filter elements are respectively marked with a digital serial number and a disposable filter design, which is convenient for the user to replace the corresponding filter element.

The No. 1 filter element is a pre-composite filter element. The main component of the filter element is polypropylene PP cotton + activated carbon rod. The function is to pre-treat the water, filter the impurities of large particles such as rust and sediment, and also carry out the free residual chlorine in the water. Adsorption

No. 2 filter is a large-flow reverse osmosis filter. It is filled with a 400G high-flow imported RO membrane. The total hardness, total solids, lead, cadmium, and other heavy metals, fluoride, nitrate, and other substances will be the RO membrane. Intercepting filtration, it can be said that this filter is the core of the entire reverse osmosis water purifier;

The No. 3 filter element is a rear activated carbon filter element. This filter element can remove two organic substances such as chloroform and nitrogen tetrachloride. The post-activated activated carbon filter can also adjust the taste of the water so that the filtered pure water has more Good taste.

It is worth mentioning that this Olansi water purifier adopts double outlet water design, and the faucet equipped with double taps can choose to output clean water or pure water, which undoubtedly greatly improves the practicality. In addition to pure water that needs to be consumed, clean water, dishwashing, dishwashing, etc. can be used with clean water. The double switch design also makes it very convenient to use.

How to choose a water purifier

How to choose a water purifier

Is the weather in your home now blowing air conditioners or air conditioners?
Although the autumn has passed yesterday, it seems that the “cool autumn” seems to be far away~~~
In the hot summer, the best “beverage” is cool and white, but under high-temperature conditions, drinking water is undergoing subtle changes all the time, invisible, but there are health threats. Therefore, installing a water purifier at home is a guarantee for water safety.
The current water purifier industry has developed rapidly in recent years, and the water purifier branding market has gradually formed. The water purifier products are diversified and diverse. So how do you buy a water purifier?

Key point 1: According to the water quality of the area
The Ministry of Ecology and Environment notified the state of surface water environmental quality in December 2018.

The water quality is excellent (I to VIII), the proportion of the section is 74.2%, and the proportion of the inferior V section is 7.1%;
The proportions of the Yangtze River, the Yellow River, the Pearl River, the Songhua River, the Huaihe River, the Haihe River, the Liaohe River, the Zhuhe River in the northwest, the Zhuhe River in the northwest, the Zhuhe River in the southwest, and the Zhejing Plate in the southwest are excellent in water quality (I to VIII), which is 74.3%, up 2.5 percentage points year-on-year; The proportion of the V-type section was 6.9%, a decrease of 1.5 percentage points year-on-year. The main pollution indicators are chemical oxygen demand, ammonia nitrogen, and total phosphorus.
Among the 111 key lakes (libraries) monitored, the water quality was excellent (I~III), the lake bank accounted for 66.7%, up 4.2% year-on-year; the inferior V water quality accounted for 8.1%, down 2.6 percentage points year-on-year. The main pollution indicators are total phosphorus, chemical oxygen demand, and permanganate index.

It can be seen that the water quality varies greatly from region to region, so the conditions for choosing a water purifier are also very different.
In some places, water quality conditions are very good. At this time, a simple ultrafiltration water purifier is used, and the problem is generally not big.
However, in areas with poor water quality, the ultrafiltration household water purifier appears to be stretched and cannot achieve the desired results. At this time, a reverse osmosis water purifier is needed.
In addition, the general water quality in the northern region is relatively hard. It is recommended to install a water softener to soften the water!

Key point 2: filter type and water purification material
At present, the mainstream filter elements on the market are PP cotton filter, activated carbon filter, ultrafiltration membrane, and RO membrane.
PP cotton filter mainly used to remove coarser particulate impurities in water;
Activated carbon filter element with the multi-pore surface, mainly used for adsorbing water, odor, residual chlorine and organic chemicals in water;
Ultrafiltration membrane with a filtration precision of 0.01 micron can effectively remove harmful substances such as sediment, rust, suspended solids, microorganisms, bacteria, viruses, rust and macromolecular organic substances in water;
RO membrane (also known as reverse osmosis membrane) is mainly used to remove all harmful substances such as pesticides, bacteria, viruses, heavy metals and ions in water. RO membrane filtration precision can reach 0.0001 microns.
One thing to note is that the water purifier level is not as good as possible. The key point is that the material is reliable.
The effectiveness of clean water is in principle determined by raw materials and production processes. A water purifier that does not meet the standard quality will not only fail to purify the water but may even cause pollution due to the material falling off.
