The pollution of water source comes from the secondary pollution of the conduit pipe of tap water and water tank on high building. Also it comes from the increase of residual carcinogen caused by the addition of chorine and disinfection in tap water. They have threatened our health fearfully. According to the survey of WHO, it indicates that 80% of disease in the world and 50% children��s death are relative to bad quality of drinking water. The digesting disease, infectious disease, various skin disease, sugar diabetes, cancer, lithiasis and cardiovascular disease inducing by drinking bad water have been up to more than 50 kinds. As the water pollution, in the world, 50 million children die every year, 35 million people suffer cardiovascular disease, 70 million people suffer lithiasis, 90 million people suffer hepatitis, and 30 million people die from liver cancer and stomach cancer.

So ��purifying water for life, keep the whole family healthy�� is the theme of modern life.

But when we face more and more water filters in the actual market and various different idea of drinking water, how do we make a correct choice?

The brochure cites the relative data of authoritative department and people. It describes the relation of water and health, and makes a summarily analysis aiming to several different drinking concepts and water filters. The purpose is to publicize correct concept of drinking water and using water, in order to make people know how to protect the health of your family and yourself, and make sure that you all enjoy healthy life.

Chapter 1: Water and Health

1. Water: the source of life

We can live some weeks without food. But, no water, after some days, we will die for dehydration. More 2/3 of human body is water, but most people don��t know the important of water.

After ingesting sufficient water, some health problems will be solved or eased, such as asthma, hypersensitivity, hypertension, high cholesterol, headache, migraine, backache, rheumatoid arthritis, angina and interval claudication (for example, clonus caused by lack of blood supply).

Water��common and passed by proper filtration water��one kind of nutriment being neglected but absolutely necessary, maybe it is needed component for making you more healthy, more vigor and longer life, but being lost.

2. Hardness of water, TDS value

Hardness means the gross amount of calcium and magnesium or CaCO3 in the water. More CaCO3, the water is harder. Less CaCO3, the water is softer.

TDS value (total dissolvability solid) is used for measuring index of all minerals in the water. TDS value not only includes calcium and magnesium (hard factor), but also includes zinc, copper, chrome and selenium, etc. Generally higher hardness of water, TDS value will be higher.

3. Water and heart disease

For many years, many researches have clued on the relation between drinking water and death rate of cardiovascular disease. Research shows hardness and total dissolvability solid are two beneficial factors. They are related with lower death rate of heart disease.

In 1979, American scientist Comstock after having summarized 50items research findings gained the following conclusions: the relativity between hardness of water and death rate of cardiovascular disease was existent. A mass of research statistics showed this kind of relativity was very obvious so that it could not appear incidental or sampling error.

Today after passing 30years�� research, gained conclusion is still: drinking soft water is easier to catch cardiovascular disease than drinking hard water.

American scientists Greathouse and Osborne researched 4200adults, who was in the range of 25-74old and distributed in 35different areas. They found death rate of heart disease in hard areas was lower than that of soft areas. One report in Oak Ridge national laboratory put forward that calcium and magnesium in hard water could lower the danger of heart shock. That research compared the male citizen in Wisconsin. They drank well water of their own farm and the result was farmers who drank soft water would have heart disease but those who drank hard water wouldn��t have problems in this aspect.

Research approved: ideal drinking water could make death rate of cardiovascular disease lower 15%. Hardness of water has specific relation with death rate of heart disease. We should do our best to drink hard water which hardness is about 170mg/L. Secondly TDS also has specific relation with death rate of heart disease. Higher TDS value, heart attack times will be less. Proper content hardness and TDS in drinking water are beneficial and compose healthy drinking water.

4. Water and cancer

According to estimation, 60%-80%cancer is caused by environmental factor. People identically thought that caner was caused by chemical carcinogen in environment, so that in the end that could be prevented. Some researches showed that chemical substance existed in surface water, ground water and tap water. Furthermore, THM��s (haloform) would be generated during the process of chlorination treatment in drinking water.

Amount of chemical substance directly or indirectly drained into the water is horrendous. Since 1974 there has been checked organic and inorganic drinking water contamination surpasses 2100types more in supply system of American drinking water. 90types among those 2100types contaminations have been confirmed that they have disadvantaged influence to health, have carcinogenic, teratogenic and mutagenic functions or have toxicity.

American scientists analyzed drinking water of 100 American big cities and found that if there was middle content TDS (about 300mg/L) in drinking water, which was hard water, leaning alkalescence (PH> 7.0) and contained 15mg/L SiO2, then death toll of cancer would be lower 10%~25%.

The full-face conclusion gained through research is: drinking water with TDS value is about 300mg/L, hardness is 170mg/L and PH is leaning alkalescence will lower the deadly fatalness of cancer.

Chapter 2: Water Pollution in Real Life

1. Pollution of water source

After the twenty years of reform and opening, the economy in our country has develop quickly, but environmental pollution becomes seriously day by day, especially the drinking water pollution. According to the stat of national environmental department, 82% of rivers in our country have been polluted in different degrees; In the seven main water systems, 40% of rivers are unsuitable as drinking water source; 78% of rivers in urban water area are unsuitable as drinking water source; About 50% of urban ground water has been polluted. According to the stat data of environmental health testing station of Chinese preventive medicine academy of sciences (1997), and evaluate according to actual drinking water sanitation standard (the standard is equivalent to the level of developed countries in seventies): 76.1% of people in our country are drinking water that cannot reach the sanitation standard. The toxin indexes exceeding 3% of standard are Fe, Mn, fluoride, nitrite and sulfate etc. There are frequent reports of endemic caused by drinking water.

It needs to point out specially: the study of poisonous matters in drinking water has been reinforced in recent years. More than 10 thousand chemicals have been inspected in water, and there are more than 100 kinds of carcinogen or matters that may cause cancer.

2. Pollution of water pipe net

After tap water leaves factory, it is transported to thousands of families through water pipe net, water tower and water tank etc. The aging of water pipe and the deficiency of cleanliness overhaul of water tank cause the secondary pollution of tap water, so it is unsafe to drink it directly. According to the inspection of environmental health testing station in Chinese preventive medicine academy of sciences, the rate of reaching the standard in 35 main cities is only 23%.

3. Adding chlorine and disinfection of water

Adding chlorine to disinfect drinking water comes in the late 1890��s. Most water factories are using the method at the moment. Is chlorine in drinking water an activator to causing atherosclerosis and cancer? In the book of coronary thrombosis, cholesterin and chlorine wrote by American M.d. Price in the late of 1960s, he thought the essential reason causing arteriosclerosis is chlorine. Nothing can deny the unassailable fact: chlorine is the essential reason of causing arteriosclerosis and relative disease such as heart failure and most unexpected death. Chlorine usually consists in the proceeded drinking water.

Is chlorine related to cancer? During the chlorination process, chlorine combines with natural organic matters and humus into latent carcinogen of haloform (THM��s). Haloform includes carcinogen such as chloroform, bromoform, carbon tetrachloride and dichloromethane etc.

American biochemist Dr. Herbert Schwartz thought:�� Chlorine is so dangerous, it should be prohibited using. Putting chlorine into water just likes start-up one time bomb.�� Cancer, heart disease and senilism all those are injury of mind and body are mostly caused by adopting chlorine treatment water. It makes us appeared decrepit evidence at young, for example, arteriosclerosis etc. If the water you drunk is treated by chlorine, you shouldn��t drink it. You can buy the water which is worked by high efficient filter and 99% THM��s is removed or proper water in bottles. Such this simple safeguarding could prevent thousands upon thousands people catching the heart disease and cancer which are two primary death killer.

4. Harm of water pollution

According to the investigation from World Health Organization (WHO), it was made clearly that 80% sickness and 50% children death have relations with the harmful water quality of drinking water. There are much 50 diseases are caused by drinking harmful water, which included digest sickness, contagion, all kinds of dermatosis, diabetes, cancer, lithiasis, cardiovascular disease etc. Owing to water pollution, there are 50 millions children death, 35 millions people catch cardiovascular disease, 70 millions people catch lithiasis, 90 millions people catch hepatitis, 30 millions people die of liver cancer and stomach cancer. The harm caused by water pollution mainly include the points as follows:

1) Water polluted by pathogency microbial contamination will cause all kinds of contagion, as cholera, typhoid etc.

2) Water polluted by harmful organic matter (as phenol, benzene, chloroform, carbon tetrachloride, agricultural chemicals, synthesize laundry agent etc.), will cause all kinds of poisoning and sickness.

3) Water polluted by heavy metal (Hg, Pb, Cu etc.) and other inorganic toxic material(chloride, arsenide, nitrite etc.), will cause all kinds of poisoning.

Chapter 3. Correct Concept of Drinking Water and Using Water

1. Pure water

The purified water (desalted water) contain little or even not mineral substance, can be attained by distilled, reverse osmosis, ion exchange or the compound way.

According to the research to the heart disease and cancer, the healthy water should have certain rigidity and some amount of TDS, as a result, the purified water, which men-made soft water without calcium, magnesium, having low resolvable total solids, is not good for the health.

Compare the animals that drink the hard water of some harmful substances, such as cadmium, lead, chlorine or fluorine with the animals that drink the soft water of same kind of harmful substances, and it turns out that the harmful substances in the animal that drink the hard water is less than those that drink soft water. The animal experiment vividly convinces that the hard water is healthier than soft water. The hard water restrains the harmful elements (such as cadmium, lead, chlorine or fluorine), decreasing their absorption, or that the minerals in the hard water supply the needed nutriments that preventing the effect of the harmful substances. The ideal rigidity of the water is about 170mg/L.

However, many people still prefer to drink the purified water in own consideration. Usually, they may think that: I know that I should drink water, but the water that is polluted by the chlorine etc chemical elements and poisonous metal is not safe enough, so I buy the distillation and reverse osmosis equipment, which can exclude all the substances in the water, then the water can be drunken safely. Is it a right choose?

In fact, the distillation and reverse osmosis equipment can produce the soft desalted water that doesn��t contain any profitable minerals, but the effect of harmful substances in this kind of soft water will be enlarged, the little harmful substances in the desalted water will have more negative influences than those of same amount in the hard water.

Accordingly, due to different reasons, drinking both polluted and desalted water is bad for our health.

2. Mineral water, magnetic water, active water and energy water

At present, there are many kinds of water products, such as mineralized water, magnetic water, activated water and energy water etc, even the water compounded with all the above-mentioned functions, which is alleged to be effective to almost all the diseases.

This is really egregious business dealing. We can ask:��Had the water been purified? Doesn��t it contain the harmful substances? Which kind of the purified technology does it adopt?��

In fact, base on the real condition of water quality in China, purifying the water to exclude the harmful substances in the water is urgent to considerate firstly, secondly, thinking over which kind of technology should be adopted to keep the profitable mineral microelements in the water, so as to keep certain rigidity and TDS value.

3. Standard of healthy water

The standard of healthy water of sparkplug includes that the water should not contain the organic matter, chlorine, heavy metal, bacteria, disease etc pollutant, and at the same time, contain certain amount of rigidity (ideal value is about170mg/L), certain amount of TDS (the ideal value is 300mg/L) and PH with more basicity (over 7.0).

4. It is insufficient of only paying attention to the quality of drinking water.

The research shows that, the pollutant in the water that flows into body can be divided to: 1/3 is from mouth, 2/3 is from washing and bathing. As a result, in order to take good care of the health of family member, it needs attach importance to both drinking and using water. We not only need solve the problem of drinking water, but also lay stress on the purifying on the drinking water in kitchen and living water in bathroom.

5. It is very important to purifying edible water.

The purifying of water in washing vegetable, rice etc is very important, or the pollutant in the water can be easily diffused its harmful effect by heating, storage etc.

6. Integrated solution to home water

The quality of drinking water is very important to our health, perhaps is also the most neglected link of all the health plans. We can produce the water that doesn��t contain the harmful substances, at the same time, keeps certain amount of rigidity and TDS value. We can also choose a suit of applicable family water filter to solve the problem of drinking water and using water in the bathroom, the filter of tap is mainly for drinking.

Chapter 4. Water Filter

1. Usual water filter

For the moment, water filters in the market mainly include the following categories:

Micro filtration filter:

Such as granule activated carton filter, PP cotton filter, ceramic filter, KDF filter, quartz filter etc. The precision of those filters is over 0.1 micron, which can��t exclude the pollutants in the water effectively enough. The granule activated carbon filter only can eliminate the peculiar smell and chlorine, but it also can��t eliminate all the poisonous chemical substances and other pollutants in the water. The Micro filtration filter usually can��t attain the standard of directly drinking water.

Super filtration filter:

Includes the single super-filtration film filter and the filter compound with super-filtration film and other medium (such as activated carbon, KDF). The precision of the super-filtration film filter is about 0.01 micron, can effectively exclude the silt, rust, resin, bacteria etc harmful substances, synchronously, keep the profitable mineral microelements. If only adopt the single super-filtration film filter, which can��t effectively exclude the peculiar color and smell, chlorine and heavy metal ion, it should be mixed with other medium, such as activated carbon, KDF etc filtration material, the effect will be better.

Reverse osmosis pure water machine:

Reverse osmosis device could remove the necessary mineral substance (calcium and magnesium) and other substances in the water, and produce highly softened water that is not beneficial for health.

Mineralizing, magnetizing, activating and energy water filter:

Usually speculate the notion, lack real virtual purge function. Even if they were claimed that they have the function of purge. They usually used the filter material of micro-filter gradation, as active carbon, ceramics filter etc., but which can��t effectively remove the harmful pollution in the water.

The main problem of drinking water is chlorine, organic compounds, THM��s and heavy metal. Wherefore, the optimal filter is the device which can effectively decrease these main pollution and reserve the beneficial substance for health as Calcium, magnesium etc.

2. Real client��s value of water filter

We can ask ourselves: ��Why do we buy water filter? What is the purpose? What characters I wish it have?�� Basing on the point of consumer, the real good water filter should have characters as following:

Good filtrating effect:

It can remove chorine, organic matters, heavy metal, bacterium and virus etc. At the same time it keeps the profitable mineral matter and trace elements. It has definite rigidity and TDS value. The produced water can be drunk directly.

Large quantity every unit:

It not only can solve family drink problems, also can meet the problems of kitchen edible purification and other water purification. It really can keep the whole family use healthy water.

Low purifying cost:

The quantity of filtrating water is large; it can realize discharge dirt self-motion. So no need to replace the filter cartridge usually, use life is long and it is low to cost.

Can use safely:

Make sure it does not make water and blow out, it can use on the safe side.

Install easily and maintain conveniently.

It is easy to install, and it very convenient to replace filter cartridge. No need to take down it by experts with special tools. You can replace it by yourself and no need special maintenance.

3. Mistake concept

Error 1: The more grades the filter has, the better the effect

The filtrating effect of water filter lies on the filtrating media not lies on the grades or figures of filter.

Error 2: More expensive water filter is better.

The frequent psychology when people are shopping, it is you get what you pay for. In fact, as the moment market of water filter is during the imported period. and most consumers know little about water purifying technology. Also some producers and dealers do the wrongful business action, so the price in the water filter market is very disordered, which make consumers feel very confused.

Error 3: I am buying water to drink, no need to buy filter.

In fact, harm matters inrush body from the approaches as following: 1/3 inrush from mouth, 2/3 are sucked as washing and bathing. Make sure your family and yourself are healthy; you need to purify your household water completely.
