Water purification knowledge has been written into the textbook, and you are still rejecting the water purifier?

Due to water pollution, 50 million children die every year, 35 million suffer from cardiovascular disease, 70 million suffer from the stone disease, 90 million suffer from hepatitis and 30 million die from liver cancer and stomach cancer. Drinking water pollution has become a major water environmental problem due to the increasing number of new diseases caused by water pollution.

At present, in terms of health education and nutrition, water is often neglected, and only “food” is ignored, while “drinking” is ignored. It is no exaggeration to say that there are more water blinds than illiterate people in today’s society. The imbalance of economic development has caused environmental pollution, water shortage caused by ecological damage, water pollution, and water degradation have already sounded an alarm to life. 80% of diseases and various nutritional disorders cause nutritional epidemics are directly related to water.

Regarding the “drinking water problem” that the people care about, Professor Li Rite, deputy director of the National Food and Nutrition Advisory Committee and the Food College of China Agricultural University, said: Many people really care about whether there are all kinds of nutrition in the water, but they ignore one. The fundamental fact – water itself is a nutrient.

Water plays an important role in our lives. It is the source of life and one of the indispensable important material resources for human survival and development. Various chemical reactions in the human body must also be carried out normally with the participation of water.

Therefore, the quality of water directly affects our health. The top 5 household water purifier is to add a threshold to the water we drink, to filter harmful substances, and to be healthy.

Many people said that when they bought a house and bought a water purifier? It is not an ornament, but a necessity for life; 80% of cells are made of water, and 80% of health is determined by water!

Nowadays, water pollution is getting more and more serious. If you do not filter the drinking water, the human body will become a filter. In fact, the water purifier is a blessing for every family. Some people may ask, I have been drinking for so many years, there is no problem at all. Why do you want to buy a professional water purifier now? Follow the footsteps of Xiaobian to understand the harm of sewage pollution on the human body!

01. Death organic matter

[Source example]: untreated urban domestic sewage, papermaking sewage, agricultural sewage, and urban garbage.

[Hazard]: Consumption of dissolved oxygen in water, endangering the survival of fish.

It causes oxygen deficiency in the water, causing the death of microorganisms requiring oxygen. These aerobic microorganisms can decompose organic matter and maintain the self-purification ability of rivers and streams. The consequences of their death are: rivers and streams are black, stinky, toxins accumulate, and harming humans and animals.

02. Organic and inorganic chemicals

[Source examples]: chemical, pharmaceutical plant emissions, paper, tannery wastewater, building renovation, dry cleaning industry, chemical lotion, agricultural pesticides, herbicides.

[Hazard]: Most organic chemicals are toxic. When they enter rivers and lakes, they will poison or poison dead organisms, causing ecological damage.

Some organic chemicals accumulate in aquatic organisms, causing poisoning after eating. Water contaminated with organic chemicals is difficult to purify. After human consumption, the safety and health of the body are threatened.

03. Petrochemical detergent

[Source example]: Dishwashing detergent used in large quantities in homes and restaurants.

[Hazard]: Most washing spirits are petrochemical products, which are difficult to degrade. Discharge into the river will not only seriously pollute the water, but also accumulate in the aquatic products, and people will suffer poisoning after eating.

04. Heavy metals (mercury, lead, cadmium, nickel, selenium, arsenic, silver, etc.)

[Source examples]: mining and smelting processes, industrial waste, tannery wastewater, textile mill wastewater, domestic waste (such as batteries, chemicals).

[Hazard]: It has direct physiological toxicity to humans and animals.

Irrigation of crops with water containing heavy metals can contaminate crops with heavy metals, making agricultural products toxic. Deposited at the bottom of the river, the bay, through the aquatic plants into the food chain, through the aquatic products such as fish into the human body.

The water purifier is a product produced for water pollution. It will reduce the damage to the human body as early as possible. Whether it is healthy or not depends on whether you have money or not, but whether you have a concept!

The human body is vital. Once it is difficult to recover, it is difficult for us to protect the health of our family’s drinking water and reduce the harm to the body. Why not?

The role of the water purifier?

The role of the water purifier?

 

The water purifier is also called a water purifier and filter. The core of the technology is the filter membrane in the filter unit. Before the water source introduced the super nanofiltration technology, the main technology of the water purifier comes from the ultrafiltration membrane and the RO reverse osmosis membrane. It is a small-scale water treatment equipment that performs deep purification treatment of water according to the requirements for the use of water. The home water purifiers usually mentioned are generally used as small filters for home use.
Water purifiers can be divided into many types according to different purification principles and processes. RO reverse osmosis technology has the highest filtration precision (filtering accuracy is 0.0001 micron). Since the pore size of the reverse osmosis membrane is only one hundred thousandths of the diameter of the hair filament, only water molecules and dissolved oxygen are allowed to pass, and all impurities such as pesticides in the water are allowed. Almost all harmful substances such as bacteria, viruses, and heavy metals are excluded. In addition, to reverse osmosis technology, there are many other filtration technologies: nanofiltration (filtration accuracy between 0.001-0.0001 micron), ultrafiltration membrane (filtration accuracy between 0.1-0.01 micron), fine filtration (filtration accuracy below 0.1 microns, Such as ceramic filtration, PP cotton filtration, etc.).
PP cotton in the household water purifier can effectively remove rust, sand, colloid and all impurities larger than 5 microns in diameter. The granular activated carbon filter has a strong adsorption capacity, which can effectively absorb residual chlorine, smell, and a difference in the water. Chemicals such as color and pesticides; precision activated carbon filter can effectively remove bacteria, toxins and heavy metals from water.
The application of deepwater purification technology in the field of drinking water makes the phenomenon of “unacceptable soil and water” soon become history, effectively solving the local diseases caused by excessive harmful minerals in groundwater in many places.

Is the water purifier used in the end? Worth loading?

Is the water purifier used in the end? Worth loading?

When it comes to water, many people don’t agree. I always say that there is no problem with water. People in a previous life have been drinking water like this. Why did we use a hot sale water purifier when we arrived in our generation? Then I will ask you, did they have fertilizer, herbicides, and pesticides in those days? How high is their food production? You may say that these are not the main problems. The problem is that water can still be drunk. If you can’t drink, the country should take care of it. Then I will tell you that you can drink, but you will get various diseases. You have not found these. Are there more and more cancers in rural areas? Are you getting younger? why? Because of the water and air, we drink have changed.

Two major sources of pollution
In the past 20 years of reform and opening-up, China’s economy has developed rapidly, but environmental pollution has become increasingly serious, especially drinking water pollution. According to the statistics of the national environmental department, 82% of the rivers in China are polluted to varying degrees; among the seven major river systems in China, the river section that is not suitable for drinking water sources is close to 40%; 78% of the rivers in urban waters are not suitable for drinking water sources. About 50% of urban groundwater is contaminated. At present, China’s waterworks still adopts traditional treatment processes, which cannot effectively remove trace contaminants in the dissolved state, especially organic pollutants, causing some harmful substances, including carcinogenic, teratogenic, mutagenic and other trace organic substances to remain in drinking water. in. According to the statistics of the Institute of Environmental Health Inspection of the Chinese Academy of Preventive Medicine (1997), according to China’s current standard of drinking water hygiene (the standard is only equivalent to the level of the developed countries in the 1970s), 76.1% of the population in China does not meet the hygiene standards. Water, the toxicological indicators exceeding 3% are Fe, Mn, fluoride, nitrate, sulfate and so on. Endemic diseases caused by drinking water are often reported in China. It is worth noting that in recent years, research on the poisoning of drinking water has been strengthened. More than 10,000 kinds of chemicals have been detected in water, and there are more than 100 kinds of carcinogenic and carcinogenic substances. Drinking water pollution has become a global public hazard.
According to a World Health Organization (WHO) survey, 80% of diseases worldwide and 50% of child deaths are associated with poor drinking water quality. More than 50 kinds of digestive diseases, infectious diseases, various skin diseases, diabetes, cancer, stone disease, cardiovascular disease, etc. due to poor drinking water quality; 50 million children die every year due to water pollution, 35 million people with cardiovascular disease, 70 million people suffer from stone disease, 90 million people suffer from hepatitis, and 30 million die from liver cancer and stomach cancer.
The hazards caused by water pollution mainly include the following aspects:
1) The water body is contaminated by pathogenic microorganisms, which can cause various infectious diseases such as cholera and typhoid fever.
2) Water bodies are contaminated by harmful organic substances (such as phenol, benzene, chloroform, carbon tetrachloride, pesticides, synthetic laundry detergents, etc.), causing various poisoning and diseases.
3) The water body is contaminated by heavy metals (Hg, Pb, Cu, etc.) and other inorganic poisons (chloride, arsenide, nitrite, etc.), causing various poisoning.

Purify water quality
So how do you improve water quality and improve water retention? The ways to improve water quality are generally:
1) Water source protection;
2) Water plant renovation;
3) Pipeline water supply;
4) Water purification of the pipe network terminal.
The protection of water sources or the renovation of waterworks can improve the quality of tap water to a certain extent, but it cannot solve the problem fundamentally, especially the secondary pollution of pipelines. Judging from China’s current national conditions, it is foreseeable that the renewal of equipment and technology in the waterworks and the overall renovation of the water pipe network will be difficult to achieve in 10-20 years.
Even with the use of pipelines for water supply, there are many problems in terms of project cost, design and construction, management and maintenance, water fee collection, health indicators, and safety level, and it only solves the problem of drinking water and cannot meet the full range of water consumption of households. Demand, no matter economically or in use, can not bring real benefits to consumers. On the other hand, the pipeline water supply can only be used for new construction. For a large number of existing residences, the water pollution problem cannot be solved due to the re-laying of the pipeline.
According to the International Health Organization study, the most effective way to enjoy healthy water is to install a water purifier at the end of the municipal water supply network, that is, the household water terminal, which can fundamentally solve the secondary pollution problem of the water pipeline, and through the depth of the terminal. The treatment is supplementing and perfecting the urban tap water treatment process so that the water quality of the tap water is greatly improved as a whole, which not only meets the needs of household drinking water but also satisfies the needs of household consumption, bathing, washing and the like in all aspects. From the engineering point of view, whether it is cost, construction difficulty, management and maintenance, use cost, health indicators, and safety level, the use of household terminal water purifier is the best choice to solve water pollution. Even in western developed countries where tap water can be drunk, 70% of households have installed household terminal water purifiers to avoid secondary pollution of the pipeline network.

Water purifier principle

Water purifier principle

The water purifier works in a variety of ways: single-machine filtration, two-stage filtration, three-stage filtration, four-stage filtration, five-level, and five-level filtration.

1. Single-stage filtration: use 1μm or 5μm PP cotton fiber filter + UDF coconut shell granular activated carbon filter to remove more than 5μm float and particulate matter in water. Clearwater source and activated carbon adsorption can effectively absorb water and odor in water. The residual chlorine improves the taste of the water. Only suitable for high-quality drinking water sources.

2, two-stage filtration: use 1μm or 5μm PP cotton polypropylene fiber filter to remove more than 5μm float and particulate matter in water to clarify the water source;

3, three-stage filtration: use 5μm PPF polypropylene fiber filter to remove more than 5μm float and particulate matter in water to clarify the water source.

4, four-stage filtration: 0.5μm CF whole diatom microporous ceramic filter can remove rust, red worm and float and particle materials in water more than 0.5μm, clarify the water source;

5. Five-level and above-level filtering: With the development of technology, the highest level of filtering is 10 or higher.

How to choose a water purifier

How to choose a water purifier

In recent years, environmental pollution, water pollution, and other incidents have occurred. If you want to have a clean water environment, it is a good choice to buy a kitchen water purifier, then how to choose a kitchen water purifier.
First, understand the principle of water purification products and their own needs
At present, there are many kinds of household water purification products on the market. The most common ones are pure water machines and water purifiers. Let us first understand their functions, advantages, and disadvantages:
1. Pure water machine, also known as RO machine, reverse osmosis water purifier, the core component is reverse osmosis membrane. The pore size of the RO membrane is only 0.0001 micron, which can effectively filter out various bacteria, viruses, heavy metal ions, soluble solids, organic matter, chemical residues and other harmful substances in the water.
2. There are two main types of water purifiers, one is ultrafiltration membrane, the filtration precision is 0.01 micron, which can filter impurities of viruses, bacteria, and larger particles, but can not completely remove heavy metals and scales; another type of purified water The filter element of the device is activated carbon, PP cotton or ceramic filter. The filtration precision is between 0.1~1 micron and the water output is large, but it is not recommended to drink directly.

Second, choose the right brand
Choosing the right brand is very important, but not the imported brand is the best. It depends on water quality. The water quality in China is complicated, and the water quality in the north and the south is different. In addition, the tap water standards in Europe and the United States are different from those in China. Therefore, some imported brands of water purification products may not be suitable for domestic water quality, so domestic products can also be considered.
Third, choose the right style
When choosing, pay attention to the convenience of use, the size of the installation space and the decorative nature. The kitchen type is generally installed in the kitchen cabinet, under the sink; while the tabletop can be placed in the countertop or in the living room, which can provide normal temperature water and hot water. The practical function and beautiful appearance make it “go down the kitchen.” Entered the hall.”

Fourth, the water volume selection
Generally, the reverse osmosis pure water machine can be divided into a barrel type and a barrel type according to the water storage mode. There is a bucket type pure water machine with about 0.15 liters of water per minute, but it is equipped with a 3.2 gallon (about 9.7 liters) water storage bucket, enough for daily drinking in a 3 or 4 family.
Fifth, choose the right purchase channel
In recent years, more and more consumers like online shopping, and the flagship store and specialty store of the water purifier brand are also very hot. Then, consumers should enjoy the convenience brought by online shopping water purification products, and they should choose the brand flagship store or authorized store or shopping platform directly purchased by the manufacturer, and the product quality and after-sales service can be guaranteed.

How to deal with the smell of water in the water purifier? The right medicine is the key

How to deal with the smell of water in the water purifier? The right medicine is the key

As people’s requirements for quality of life are getting higher and higher, many people nowadays will consider decorating a water purifier in their home life. After all, everyone knows that the current water pollution is still very serious.

However, when using a water purifier, many people will encounter such a problem, that is, the water from the water purifier will have an odor, so what should we do if we encounter this situation?

Don’t worry, today Xiaobian takes you to understand the reason, the right medicine is the key!

01
The filter element is dirty or has reached the end of its life.

If our water purifiers are not used for a long time, it may be caused by dirty filter elements.

Therefore, it should be cleaned and reused. If you don’t, you can contact the after-sales service personnel. Of course, this is the case, that is, the life of the filter element has arrived, and everyone can replace it in time.

02
Not used for a long time

If this happens, it will also cause the water in the water purifier to smell bad. Because there is no one in the family for a while, the water purifier will not be used. If the used filter element is stopped in the middle and then used again, it will appear. The water in the water purifier has an odor.

03
Choosing a good brand is very important

If the water purifier can’t find the cause of the water, it may be related to the quality of the water dispenser. Before purchasing the water purifier, it is recommended that you choose a water purifier brand with reliable quality and complete after-sales service.

This also avoids frequent loss of filter quality or the use of a water purifier.

What is the relationship between water purifiers and water pollution?

What is the relationship between water purifiers and water pollution?

Stop the water! There is no water at home. . .

It’s coming, the water is so turbid, it’s disgusting. . .

But why does the water in the house usually look like there is no problem;

And when it comes to water, it will become filthy after coming back to the water?

First, let’s take a look at a short video from CCTV. This will give us the answer.

Our pipes are also the same as the water tanks. Usually, a small number of impurities will flow into our homes;

However, when the water is stopped, the water pressure becomes larger when the water is supplied; then the impurities previously deposited in the pipeline are washed out, thereby causing the water in the house to become smashed!

Another is that sediment and other substances enter the water because of the rupture of the water supply pipeline;

Of course, the tap water pipeline should be cleaned regularly, otherwise, the tap water in the home is even more terrible;

In fact, our water will be polluted more or less after passing through pipelines and water towers;

Just look at the frequency of cleaning, and the amount of impurities in the water is less;

Tap water is a necessary source of water for our family’s life if this water source cannot be guaranteed;

Then our health will be threatened!

Is the water purifier needed?

need!!!

Because we have no way to effectively solve the secondary pollution problem of tap water.
Water; as the source of life, is a precious resource for human survival and development. Our lives are inseparable from water resources, and all chemical reactions taking place in the human body are carried out using water as a medium. Without water, nutrients cannot be absorbed; oxygen cannot be delivered to the desired site; nutrients cannot reach its site of action; waste cannot be discharged; metabolism will stop.

Water pollution, the use-value of water caused by harmful chemicals is reduced or lost, polluting the environment. Acids, alkalis, oxidants in sewage, and compounds such as copper, cadmium, mercury, arsenic, organic poisons such as benzene, dichloroethane and ethylene glycol will poison aquatic organisms and affect drinking water sources and scenic spots. When the organic matter in the sewage is decomposed by microorganisms, the oxygen in the water is consumed, which affects the life of the aquatic organism. After the dissolved oxygen in the water is exhausted, the organic matter undergoes anaerobic decomposition to generate an unpleasant gas such as hydrogen sulfide or mercaptan, which further deteriorates the water quality. Water pollution is really there. Even if you don’t look at water pollution reports or news about water pollution, you can’t guarantee that the water you drink every day is clean. Humans can no longer hide their ears.

So what is the relationship between water purifiers and water pollution?

Due to the development of society, the destruction of human activities has seriously polluted the water on the earth, and people’s domestic water has attracted serious pollution. According to the survey, one-third of households worldwide have difficulty using water every year. There are 45 million people who are assessed to suffer from water pollution each year and continue to grow each year. The number of deaths due to water pollution is 30 million, most of them children. For China, most cities have water safety hazards. In recent years, factories have gradually shifted to rural areas, and some rural drinking water problems have been seriously polluted. Therefore, the health hazard of water pollution is imminent and must be resolved.

Water pollution has prompted the birth of water purifiers. Water purifiers can be said to be essential household appliances to ensure the safety and hygiene of household water in this era of pollution. According to the principle of filtration, the water purifier can filter the tap water from the filter through the filter, which can effectively remove acid, alkali, oxidant, copper, cadmium, mercury, arsenic and other compounds, benzene, dichloroethane, Organic poisons such as ethylene glycol; sediment, rust, bacteria, etc. in ordinary water can be easily removed.

How to choose a water purifier? This time we talked seriously

How to choose a water purifier? This time we talked seriously

When did you have the idea of ​​buying a water purifier? Probably when you found unidentified floating objects in the water at home. The author’s hometown is located in Hebei Province. The water quality in the north is hard and the heavy metal calcium and magnesium ions are too high. It is a well-known “common sense”, so it is not surprising that the scale in the kettle is not too long.
However, with the driving of house prices in Beijing in recent years, the Linjing small town where the author is located has also begun to build large-scale construction projects. Various real estate projects have been developed and constructed one after another. I have never felt that water quality has changed. I began to slowly discover that there will always be an unknown after the water is boiled. Some of the mushy floats are very disgusting… I have read a lot of information, although it can’t prove that it has a direct relationship with the “Da Xing Tu Mu”, but this water really can’t continue to be confused and drink… With the water pollution problem in recent years, it is more and more obvious. Aggravated, I think it is time to start a water purifier~
In the purchase of water purifiers, the author has done a lot of homework, basically understand that there are currently types of household water purifiers such as ultrafiltration/nanofiltration/ RO, after the comprehensive comparison is still more inclined to start RO water purifier, because In general, the ultrafiltration membrane is the largest of the three intermediate pores. Its micropores are less than 0.01 micron, which can completely filter harmful substances such as bacteria, rust, and colloid in water, but because of the slightly larger pore size, it does not affect heavy metal ions. To the filtering effect.
Although the pore size of the nanofiltration membrane is smaller than that of ultrafiltration, it filters out most harmful substances including heavy metal ions but retains Ca+, Mg+ trace elements, and small particle size pollutants. In recent years, the hot RO reverse osmosis membrane has a smaller pore size. After the high pressure is applied by electricity, although the wastewater will be more than doubled in the process of purifying water, the water filtered by the RO water purifier is very clean. Because even the minerals are filtered together, it can be regarded as true pure water.
Some people may say here that the RO water purifier filters out the minerals that are beneficial to the human body. What else does it choose? But in fact, everyone ignores the point that the body can drink through the diet. Supplement the necessary trace elements, and in daily life, as long as you pay attention to a reasonable dietary mix, there will be no shortage of minerals. For the specific dietary guidelines, please refer to the “Chinese Resident Balanced Pagoda” published by the Chinese Nutrition Society in 2016. As shown above. Therefore, when purchasing a water purifier, the author is still the most recommended RO water purifier, because the real pure water is the daily drinking water we need.
At present, there are many brands and models of RO water purifiers. In fact, for such products (such as air purifiers), there is no need to pay too much attention to brand factors, because the water purifier itself does not have much cutting-edge technology. The key lies in ” “Stacking” and “work”, because the principle of the water purifier is very simple, that is, the water filter is cleaned by the filter element, and the RO product needs to be energized and pressurized to achieve reverse osmosis, and there is no other so-called core technology. Why do you want to emphasize workmanship, because just like the same piece of iron, the things that the different ironsmiths make are also very different? This is the impact of good work and bad work on the product. When it comes back to the water purifier, there is another need to pay attention to the humanization function, such as filter reminder, water source switching, remote monitoring, etc., and all of this constitutes my water purifier purchase demand.
“People rely on the clothes horse to lean on the saddle, so look at the appearance first.” You will say that this thing is not all under the kitchen. Is it important to look good? Well, I can only say that this is a plus item. Generally, there is no penalty. If you look good, it is a pure extra point. At present, the simple, “sexual cold wind” is more modern and more popular with young consumers. Under the premise of “hidden beauty” in the home environment, The water is usually placed in the kitchen cabinet, so it is a matter of opinion for the appearance of the demand.
▲The role of the water storage bucket in order to increase the flux
The point to be emphasized here is that the current RO water purifier is divided into a barrelless type and a barrel type. What is the difference between the two? In fact, unlike the traditional RO water purifier with a clean water bucket, the benefits of the waterless bucket design are obvious. First of all, it saves space. It can be understood that as long as your kitchen space can accommodate the three-dimensional shape of the fuselage, you can properly avoid the installation problem, and the traditional bucket water purifier must be reserved. Under the premise of body space, there must be enough storage bucket space.
Why is it more recommended to have no bucket?
At this time, you may have to ask? What is the bad effect of the bucketless design? In fact, the main reason for the bucket design is that the water purifier flow of the RO water purifier itself cannot reach the desired water output speed. It is necessary to carry out clean water in advance, and then store it in a water purification bucket for use. Therefore, there is another health hazard in addition to the landfill water purifier, that is, if the water in the bucket is not used for a long time, It becomes the residual water and does not rule out the risk of breeding bacteria. After all, the inside of the water storage tank is not a completely sterile environment.
▲UV sterilization gradually becomes standard
It is worth mentioning here that, from the final purified water reaching the faucet, there is actually a circulation process. How can the bacterial breeding problem in this process be solved? In order to eliminate this last hidden danger, many water purifier manufacturers are In the final part of the affluent, UV-ray sterilization and the like are set up to form the final purification.
▲After the replacement cost of a brand filter
In addition to the above factors, the main job of purchasing the RO water purifier is to select the internal filter element. Here we also make a brief overview. The water purifier filter is mainly divided into the following types:
Primary filter: PP cotton
The PP cotton filter is an indispensable primary filter on the water purifier. It can remove large particle contaminants such as sediment and rust and can protect the rear filter element from large particle contaminants. The replacement period of the PP cotton filter is 3 -6 months.
Secondary filter: pre-granular activated carbon
The granular activated carbon filter can effectively remove macromolecular organic matter, iron oxide and residual chlorine, and can significantly reduce the turbidity of the influent water, and the service life is 6-12 months.
Three-stage filter: RO reverse osmosis membrane
A water purifier can be classified as an RO water purifier, that is to say, this RO membrane, the initial application of RO is to let the astronauts drink their filtered urine in outer space… Of course, the RO reverse osmosis membrane has now For civilian use, it is widely used in water purifiers. The better quality brands are American Pottery/Japan Toray/Korea Shihan… Of course, there are also domestic films, but the best RO film recognized by the industry is American Dow, which is also the hard cost component of an RO water purifier, RO The reverse osmosis membrane effectively removes antibiotics from organic heavy metals, nitrates, and bacteria, and has a filtration accuracy of 0.0001 μm and a service life of 18-36 months.
Four-stage filter: post-granular activated carbon
The main purpose of the rear granular activated carbon filter is to improve the taste because the pure water will be slightly dry after the previous steps of filtration, so in order to finally get enough water into the user’s mouth, this filter is also very necessary. The service life is 6-12 months.

Do you need a water purifier? Yes, you need it!

Do you need a water purifier? Yes, you need it!

At the end of summer and autumn, people’s drinking water will increase greatly.
Microorganisms are more susceptible to reproduction during hot seasons.
The safety of drinking water is also particularly prominent.
Some people pick up a cup of water directly,
Some people take water from the faucet and then boil it with a kettle.
But are these waters really safe and clean?
It’s really Too Young Too Naive.
It can only be said that the ideal is full, but the reality is very skinny.
01
