Drinking water is clean and safe, compared to long-term drinking unclean water a heaven and earth. Brand bias can be referred to Anzhiyuan 3M beauty and so on.
How big is the role of the water purifier
As a salesman who has been selling water purifiers for nearly 5 years, I have to say that the water purifier industry is in chaos;
If you want to buy a water purifier that suits your needs, please make sure to read and think about this short article:
You may have never thought about it: water purifier manufacturers produce the same brand, different models and different price points. The water purifier manufacturers produce the same brand, different models, different price points, is there a problem?
Have you ever wondered if a low-priced model (the so-called 3-stage) of water purifier produced by a certain factory can meet the water purification requirements?
And if so?
Then it produces high-priced models (the so-called 5 or 8) of water purifiers are necessary?
And much more expensive?
But what if the higher-priced models are the only ones that can actually purify water?
Then selling a low-priced model of water purifier is not a pitfall and fool customers?
In order to adapt to the market of various consumer groups without regard to the quality of whether the standard is sold on the enterprise is trustworthy? It may say that in fact, the low-end of our products have reached the standard, high-end but more perfect function (bullshit, in fact, he is telling you to use or not the same, the tap water is also up to standard before entering the home to use)
Therefore: when buying a water purifier price is not important, the brand is also unimportant, the only important thing is only the effect!
Imagine: even if you only spend 200 yuan to buy a water purifier, but you spent 200 yuan to buy a water purifier has no effect! That is a waste of 200 dollars. Do you think so?
How to choose a cost-effective water purifier? You can refer to the following important indicators to buy:
1. Look at the cartridge: the core of the main water purifier, its strengths and weaknesses have a direct impact on the water purifier purification indicators.
First of all - focus on the cartridge can filter impurities, so that the water looks clearer (it can be said that any water purifier can do, however, different filtration methods have very different effects)
Filter membrane: the market is also flooded with a variety of names of the filtration membrane, pp cotton, etc.; in fact, the role of only one filtering The impurities above a certain specification.
Reverse osmosis: the most common on the market, 99% filtration rate has become its biggest selling point; the disadvantage is also obvious is too clean (there is no beneficial minerals; and can not filter bacteria, viruses and other micro-organisms) filtration speed is slow by the way, Popularization: the scope of reverse osmosis applications - space water, purified water, Distilled water and other preparations; alcohol manufacturing and degradation of water; medicine, electronics and other industries in the pre-preparation of water; chemical process concentration, separation, purification and water preparation; boiler make-up water desalination soft water; seawater, brackish water desalination; papermaking, electroplating, printing and dyeing, food and other industries and wastewater treatment; urban sewage deep treatment.
Second - focus on the cartridge can filter odor, improve taste (any one of the installation of activated carbon water purifier can do, however, the cartridge structure of different effects, life, price difference is huge)
Granular activated carbon cartridge: a short period of time to remove the odor, but a long time will be washed out of the waterway lost filtration effect. Disadvantage: the service life is uncertain (the user has to wait until the cartridge loses its purification ability to know)
High-density activated carbon: long service life; lumpy structure, will not form a watercourse; disadvantage: complicated production, expensive (compared with the equivalent weight of granular activated carbon on the high side of the 100-fold) due to the protection of patents (high production costs)
Lastly, we are concerned about the ability to kill the odor. - - Concerned about whether the water purifier can kill microorganisms, microorganisms in the viruses, bacteria are potentially pathogenic must be removed (general products can not kill microorganisms; some products can kill microorganisms, but the technology determines the risk of purification)
Chemical sterilization: the use of chemical cartridges to kill microorganisms; disadvantages: chemical residues that affect the taste and health (treatment: chemical cartridge installed after the improved taste of ionic cartridge or activated carbon cartridge; so that consumers can not be directly detected from the taste of abnormalities, to enhance the difficulty of identifying chemical residues)
Ultraviolet sterilization; sterilization rate of up to 99%; drawbacks: need to be energized (potential leakage of security risks; of course, can be avoided through the potential risks of wireless power conduction technology) But the technology is protected by patents (high production costs)
A qualified water purifier to achieve: filtering impurities, retain minerals beneficial to the human body, improve the taste of drinking water is enough
A high-quality water purifier must be: filtering impurities, retain minerals beneficial to the human body, filtering a variety of chemical ...... >>
What are the benefits of a home water purifier?
Rongsheng home water purifier, can remove bacteria, viruses, heavy metals, organic harmful substances in the water ... It can remove bacteria, viruses, heavy metals, organic and harmful substances from the water, retaining the essence of water.
Why does a water purifier work? 40 points
Water purifiers generally use the following three ways to remove impurities:
(1) Filtration. The water purifier is equipped with a filter, which can filter out solid particles and even bacteria in the water through coarse, fine and ultra-fine filtration;
(2) adsorption. Activated carbon adsorption device in the water purifier, the water through the activated carbon, can filter out and adsorption of many kinds of impurities, including bacteria;
(3) ion exchange. Ion exchanger set in the water purifier, the water through the ion exchanger, some of the anions in the water are exchanged for hydroxide ions, some of the cations are exchanged for hydrogen ions, hydroxide ions and hydrogen ions combined into water molecules, the number of anions and cations in the water is reduced.
Small domestic water purifier generally includes "filtration" and "adsorption" two functions, large water purifier may also include "ion exchange" function.
What does a water purifier do?
Purification of drinking water, to achieve the standard of direct drinking
Water purifier is really useful
The benefits of pure water is too great - see the five major misconceptions about drinking water
1, drinking boiled water is the safest
2, the barrel of water is safe and convenient
3, pure water lacks minerals and water is convenient
3, pure water lacks minerals and water is convenient
4, pure water lacks minerals and water is convenient.
3, pure water lack of minerals and trace elements
4, drinking mineral water is good for health
5, grandparents did not drink pure water, do not also live
1, drinking boiled water is the safest
Many people have long believed that drinking raw water to get sick, so you must drink boiled water. This is for the past less polluted water, is not an effective means of sterilization, disinfection, but at the same time there are many negative impacts such as: 1, boiled water only kills bacteria and some viruses, bacteria and viruses killed dead body still exists in the water; into the human body, that is, to become what is known as the medical "heat source body", the common clinical "Nameless heat" causes more from this. 2, the process of boiling water is unable to get rid of excessive heavy metals, scale and carcinogens in the water. 3, the water in the heating process, the loss of oxygen is too much. Accompanied by the "gurgle gurgle" of the boiling water phenomenon, the oxygen in the water are basically evaporated, the human body needs calcium, magnesium and other minerals into the scale deposited at the bottom of the pot. Cool water watering flower flower death, fish fish death is common sense, drinking boiled water is not conducive to the human body oxygen supply. Long-term drinking is more detrimental to the metabolism. 4, with aluminum or iron containers made of boiled water, nitrite nitrogen in the water (a strong carcinogen) will increase significantly. According to data reports, with iron containers when boiling water, nitrite nitrogen in the water will increase by 23 times, and with aluminum containers when boiling water, nitrite nitrogen in the water with the extension of the boiling time and a significant increase in the boiling time, after five minutes for the original water more than ten times, after twenty minutes of boiling is increased to nearly 100 times.
Second, drink bottled water safe and convenient
With the continuous improvement of people's awareness of drinking water, many families buy bottled water. But drink to drink the problem came out:
1, simplify the means of purification: some manufacturers to save costs, simplify the means of purification, resulting in substandard water quality. Individual manufacturers even tap water directly into the barrel; the *** masked in the tap tap, the cost of this water will not be more than 2 yuan, sold to consumers became 8-10 yuan.
2, the quality of the bucket is not qualified: some buckets even use discarded blood transfusion bottles, disks as materials! Meet the health standards of the bucket price of about 35 yuan, and recycled old plastic to do the cost of dark-colored bucket only about 8 yuan. How can such a high price difference not make people red?
3, the freshness of the water can not be guaranteed. Water is active, the fresher the better. Some families a week or even two weeks to finish a bucket of water, need to pay attention to: a variety of barrels of water should try to open 2 to 3 days after the use of the end, otherwise the air brought into the bacterial reproduction, will cause the water bacterial overload! Water is easy to aging, can not guarantee the freshness of the water. But we ordinary people at home the fastest time to drink 5 days.
Third, the lack of minerals and trace elements of pure water
Some people think that drinking pure water without nutrition, no trace elements, is not conducive to human health. In fact, this statement does not have sufficient clinical practice and the corresponding theoretical basis:
1, in accordance with medical common sense, water in the human body, mainly as a "transport captain" position, the body only through the water in order to transport the nutrients needed by the body's organs and 60 trillion cells, while the body's endocrine system discharges waste and toxins transported to the body, the body's endocrine system. Endocrine system discharged garbage and toxins transported to the corresponding organs out of the body. Therefore, the water has to maintain the shape of the cell; have to improve the role of metabolism; but not to the human body to provide the role of nutrition.
2, China's environmental health monitoring water quality experts Yang Zhenbo pointed out: "In fact, only living plants can be absorbed from the soil and the use of inorganic minerals, organic minerals converted by the plant can be absorbed by the human body and animal utilization, almost no one can be from inorganic minerals in the intake of nutrients, and no one can be effectively applied to the inorganic minerals in the body. For example, if the human body feels a lack of calcium should be taken from milk or calcium tablets (active calcium, organic calcium), when there is a lot of calcium in the water is useless. The minerals that are drunk into the body and cannot be absorbed will be excreted through the liver, kidneys and other organs of the body, thus placing an extra burden on the internal organs. This is a major cause of some chronic diseases."
3, some of the data is more justified: a cup of milk calcium equivalent to 1200 cups of mineral water calcium, a pound of beef iron equivalent to 8200 cups of mineral water iron, a cup of orange juice contains minerals that are beneficial to human health, than the unprocessed drinking water 500 times higher. These illustrate that true supplementation relies on food rather than water! Don't just assume that you can get your nutrients in water. This is one of the biggest misconceptions! Do you choose a nutritious meal or do you get the same amount of minerals by drinking tons of water?

What are the benefits of drinking water filtered by a water purifier?
HANYU Comfort Home warm tips: the use of water purifier, can effectively filter all kinds of pollutants, to achieve the standard of raw drinking, and the cost is relatively low. Water purifier is a purely physical filtration method, can effectively remove all kinds of pollutants, such as bacteria, residual chlorine, heavy metals, scale (calcium and magnesium, etc.), volatile substances, rust, sediment, etc., and to retain the beneficial trace components of the human body, to enhance the quality of water. The water tastes good and can be drunk directly without boiling, so it is the most ideal solution for drinking water.
What are the benefits of a home water purifier
Advantages and disadvantages of a water purifier
The choice of what kind of water purifier, mainly based on the quality of water in the location where you live, the individual's drinking water needs, and processing; treatment effect to decide. Currently on the market; a variety of water purifiers, the following for you to analyze a; under a variety of water purifiers; the advantages and disadvantages of the device
1, cartridge-type water purifiers:
This water purifier; the use of the filter: the core structure, according to the different needs: the demand, can be equipped with different cartridges, the advantages of the cheaper, the filtration accuracy; higher (containing ultra-filter cartridges). The disadvantage is that the life of the cartridge is relatively short (for example, PP cotton life in 3-5 months, activated carbon life in about half a year, ultra-filtration life of 1-2 years), the water output is small, only suitable for drinking.
2, water purifier:
This water purifier uses RO reverse osmosis technology, first appeared in the aviation industry, is to solve the problem of drinking water for the airmen and research and development, the advantages of high precision water (in addition to the water molecules, any substance can not go), the disadvantage is that the purified water is too pure, the lack of beneficial trace elements for the human body, an average of a cup of pure water, to produce 3 cups of waste water! The average out of a cup of pure water, to produce 3 cups of waste water, at the same time must use electricity.

3, ionized water machine:
Through the electrolysis of water electrolysis for acid and alkaline two kinds of water, alkaline water used for drinking (because the human body is an acidic structure, often drink alkaline water, you can regulate the acid/alkaline balance to promote the metabolism), acidic water used for bath (or used to sterilize the disinfectant), and at the same time through the electrolysis, change the molecular group of water. electrolysis, change the molecular group of water (change water into small molecular group of 6 molecules). This type of water machine was first used as a medical device, for common skin diseases have a certain degree of efficacy. His disadvantage is the high cost (ordinary about 6 thousand), while the pH value of water also depends on the electrolysis version, which requires electricity.
4, magnetized water machine:
Advantages: through magnetization, change the molecular group of water, more conducive to human absorption. Disadvantages: people with gastrointestinal disorders should be cautious, because the magnetized water has a certain *** on the stomach.

5, central water purifier:
The water purifier is installed in the home of the total water intake pipe, so that all the water in the home are purified, the advantages of a long life of the filter media (the shortest is also 5 years), easy to operate, and at the same time with the function of the backwash, you can prolong the life of the filter media. The disadvantage is that the purification precision is not particularly high, if used to deal with drinking water, the effect is not particularly good
What is a home water purifier what are the characteristics?
What
is a home water purifier what are the characteristics? Now introduced. Household water purifiers are divided into RO reverse osmosis membrane water purifiers and UF ultrafiltration membrane water purifiers according to water purification technology. Its core component is the introduction of reverse osmosis membrane from the United States, the use of the most advanced international reverse osmosis water treatment technology for the preparation of pure water, without the use of any chemical or bacteriostatic agent. Household water purifier according to water purification technology is divided into RO reverse osmosis membrane water purifier and UF ultrafiltration membrane water purifier. Reverse osmosis membrane water purifier, also known as RO reverse osmosis water purifier, its core component is the introduction of reverse osmosis membrane from the United States, the use of the most advanced international reverse osmosis water treatment technology for the preparation of purified water, without the use of any chemical or bacteriostatic agent, the use of physical technology, the human body and the environment does not have any harm.
The water treated by the reverse osmosis water purifier has the characteristics of clear, sweet, bacteria-free, low salt, no scale, no pollution and contains certain trace elements and minerals. Suitable for drinking, easy for the body to absorb, activate human cells, promote metabolism, enhance immunity and resistance, health and safety, suitable for poor water quality areas. But the disadvantage of reverse osmosis machine is more wasteful of water, many companies are trying to find ways to solve, but as of now there is no too good solution. In addition, the individual harmful organic substances in the water can not go out, in short, not very suitable for China's water shortage
Household-type water purifiers generally do not have a motor, do not need a power supply, relying on the water pressure to drive filtration, there is no storage tank water is generally ambient water, such as the need for hot water or iced water need to take over the line machine / water dispenser separately. Its main function is: to remove residual chlorine in the water, impurities, odors and bacteria and other harmful substances, filter out impurities in tap water, rust, some bacteria, viruses, colloids, etc., some models have the function of scale inhibition. 1, PP cotton filter water purifier: that is, equipped with a variety of PP cotton filter single cartridge water purifier, the machine is generally low-priced, but the filter is more likely to be clogged, the replacement frequency is higher, the precision of filtration is not very high, this is only for the initial filtration of water, not directly drinkable.
2, RO reverse osmosis water purifier: water purifier can completely remove harmful substances in the water, after purification of water is pure water. The pressure of the water is not enough for its working pressure, so it also needs a booster pump, with the help of electricity and pressure. Its biggest disadvantage is that there is more wastewater, generally to filter out about 50% of the wastewater. It is more expensive to purify, produces less water, and can only be used to solve the drinking water problem.
3, activated carbon filter: activated carbon super strong adsorption can remove foreign colors and odors in the water, but can not eliminate bacteria in the water as well as some other harmful substances, simple activated carbon water purifier with sediment, rust removal effect is also relatively poor.
4, water softener: water softener is the biggest effect is to be able to soften the water, reduce water hardness, and then reduce the production of scale. The general softening method is to use regenerative sodium resin to replace calcium and magnesium ions in the water. But it can not play a role in purification, and can not remove a variety of harmful pollutants in the water.
5, ultrafiltration machine: ultrafiltration water purifier can effectively remove sediment, suspended solids, rust, bacteria, colloids and some macromolecular organics in the water, you can effectively retain some of the beneficial minerals, trace elements. Its advantages lie in the long service life of the cartridge, large water output, no need to add electricity and pressure, and relative to other purification equipment, the cost is low, is very suitable for life with water purification. You can follow the above.
