How to choose a household water purifier, after reading this knowledge, you will not worry about choosing a water purifier in the future.

In recent years, with the development of society, the problem of air and water pollution has become increasingly serious. Everyone has gradually begun to focus on the quality of domestic water and drinking water. Traditional methods such as heating and boiling tap water and using water dispensers have long been unable to meet everyone’s requirements for healthy water. The emergence of household water purifiers has gradually attracted more people’s attention and has gradually become one of the necessary electrical appliances in every family. However, as far as the market development of domestic water purifiers is concerned, it is still very immature, and everyone lacks awareness of water purifiers. Many people want to buy a household home water purifier but they don’t know which water purifier is better. Today, Xiaobian introduces some common water purifiers in detail, hoping to help you choose the right hot sale water purifier.

First of all, what is the best choice for household water purifiers? We can choose according to the purpose and function of the water purifier. There are various types of household water purifiers on the market in the market. The names of pure water machines, water softeners, straight drink machines, etc., make many consumers dazzled when they choose. I don’t know which one to choose. Household water purifiers are divided into pre-filters, central water purifiers, central water softeners, and terminal straight drinkers. Of course, their respective functions and uses are different. Consumers must make these products before purchasing. Know clearly.

Pre-filter: Generally, it is installed on the surface of the water meter of the inlet pipe. It is the first coarse filtration equipment for the whole room. It can filter out the sediment, rust, large particles and so on in the tap water. It also stabilizes the water pressure and protects the water purifier equipment connected to it. Central water purifier: The most important thing is to carry out a more effective purification of water by the adsorption of KDF filter and activated carbon, which can remove many sediments, rust, bacteria, suspended solids, algae, macromolecular organics, etc. A poisonous and harmful substance can well retain the minerals beneficial to the human body in tap water, and the treated water can directly reach the quality standard of drinking water. Central water softener: This kind of water purifier is made of natural resin to exchange calcium and magnesium ions in water, which can reduce the hardness of water and soften water quality. It is called “soft water machine” and can also reduce water mine. The wear and tear of the clothes on the clothes and skin can protect our skin, protect the clothing, and prevent the minerals in the water from producing yellow spots in the sanitary ware, tableware and other supplies, and prevent the water pipes and water heaters from generating scale, which can be better and convenient. Everyone’s domestic water. Terminal straight drink machine: It adopts high-precision five-stage filtration design. The tap water is filtered at the water terminal, and the water directly reaches the quality standard of raw drinking water. Unscrewing the tap water tap can directly Drinking, to achieve the effect of the instant drink, avoid secondary pollution of water quality, water activity is relatively large, retaining high oxygen, can promote human metabolism, enhance the vitality of human cells. The water purifier has an exclusive space Technology, super five-level purified water effect, can give good quality water to the upper layer of the whole household.

Secondly, we can choose the water purifier based on the actual needs of our home. If the water quality of the household is relatively good, the water does not have obvious abnormalities such as color and odor. You can choose a combination of a pre-filter and a central water purifier to remove sediment and rust from the water. Bleaching powder, bacteria can be; if the water quality in the home is relatively poor, you can choose the combination of pre-filter and central water purifier plus terminal straight drink machine, which can ensure the health of drinking water well; The scale phenomenon is obvious, the hardness of the water is relatively high, then the water needs to be thoroughly softened, and then everyone needs to use a water softener to facilitate domestic water. Under the premise of economic conditions, or the effect of water treatment is relatively high, you can choose to install a full set of water treatment system so that drinking water and domestic water can get the best treatment effect.

Finally, we can also purchase from the energy-saving and efficient aspects of the water purifier. In addition to the functional use of household water purifiers and the choice of water quality, a good household water purifier must have a collection of energy-saving, high efficiency, large capacity, and many other characteristics. The water purifier must also be silent and non-leakage, using a “can-free” integrated design, which can save half of the space. The water purifier completely loses the supercharged model of the traditional electric pump and opens up the innovative water-to-water supercharging technology. It does not need to be plugged in and only requires municipal water pressure to operate. There are many types of household water purifiers. Which one is the best choice can not be generalized. Each water purifier product has its unique features and uses. Such a household water purifier is the best as long as it is suitable for the water needs of the home.

What is the principle of the water purifier?

Most of the water purifiers adopt the progressive structure of the screen filter principle. The multi-stage filter elements are connected in series, and the precision of the filter elements is arranged from low to high in order to realize the multi-stage filter element to share and retain dirt, thereby reducing the filter plugging. And the number of manual sewage, wash and wash, and the period of replacement of the filter. Another new design idea is to apply the self-cleaning structure of the principle of mass distribution. Its design idea is no longer to provide as much space as possible for contaminant pollution, but to adopt a principle of separation to separate a small part of the clean water, at the same time, as far as possible, let the raw water flow as usual, so that the dirt is taken away with the water flow in time, so that the water does not rot. In this way, both purified water is obtained, and it is not easy or difficult to precipitate dirt in the machine, avoiding secondary pollution and greatly reducing filter loss, and the water quality is better, safer, and energy-saving than low carbon. This new principle of self-cleaning water purifier won the gold medal of the 7th International Invention Exhibition, which is a one-in and two-out structure. It improves the concentration of raw water impurities in the machine due to the structural defects of the traditional water purifier. The higher the accumulation, the more the sewage becomes, and therefore the self-cleaning water purifier has no concept of sewage and sewage water purifiers instead of washing water. With the improvement of living standards, the popularity of water purifiers will become wider and wider, and new technology products are better meeting people’s needs.
1. Folding single-stage filtration: using 1μm or 5μm PP cotton fiber filter + UDF coconut shell granular activated carbon filter, can remove more than 5μm float and particulate matter in water, clarify water source, activated carbon adsorption can effectively absorb the odor of water, The residual chlorine in the water improves the taste of the water. Only suitable for high-quality drinking water sources. Generally, the tap water source cannot be drunk after being filtered.
2. Folding two-stage filtration: use 1μm or 5μm PP cotton polypropylene fiber filter to remove more than 5μm float and particle material in water, clarify the water source; use 5μ CTO pressure sticking activated carbon filter to effectively absorb the odor in water, partially remove organic Inorganic impurities can effectively adsorb residual chlorine in water, improve the taste of water, and only adapt to high-quality drinking water. Better than single-stage filtration. Generally, the tap water source cannot be drunk after being filtered.

Adapt to the tap water source with good water quality, combined with the pre-treatment process, the treated water reaches the CJ94-1999 drinking water quality standard water, which can be directly consumed.
4. Folding 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; use 5μmCTO pressure stick activated carbon filter to effectively absorb water Color odor, partially remove organic and inorganic impurities, can effectively adsorb residual chlorine in water, improve the taste of water; use 0.1μm CF whole diatom microporous ceramic filter: can remove Escherichia coli, Salmonella, Staphylococcus aureus larger than 0.1μm in water , Pseudomonas  and mold pathogenic bacteria; PPF polypropylene fiber + UDF coconut shell granular activated carbon two-stage filter can remove the odor of water, so that the purified water has a sweet and fresh taste. Adapted to the general tap water source, combined with the pre-treatment process, the treated water reaches the CJ94-1999 drinking water quality standard water, which can be directly consumed, which is better than the three-stage filter.
5. Folding five-level filtering: Now with the development of technology, there is a maximum of 10 or higher filtering levels.
• PP cotton: 5-micron aperture filter to remove all kinds of tiny impurities such as residual sediment and rust in the water.
• KDF (copper-zinc alloy body precision activated carbon) removes water-soluble lead in water, heavy metals such as mercury and arsenic, and supplements zinc elements beneficial to the human body. It integrates adsorption and filtration into one and removes free chlorine and chloroform in water. The rate is as high as 96% and further removes pesticide residues from the water. Fertilizers and radioactive materials, and have the effect of discoloration and odor removal. Deeply adsorbs substances such as halogenated hydrocarbons and organic substances that are harmful to the human body, and increases the sweet taste of water. The filter has a long service life and a metal removal rate of up to 99%.
• Resin: For areas with high water hardness, the hard water with high calcium and magnesium content is alternately converted into soft water to prevent the human body from suffering from stone disease due to long-term consumption of hard water.
• Anti-oxidation filter: Free radicals in the body are an oxidized product, so they can be removed by redox. The oxidation-reduction potential is the lowest, the better the effect, the high-energy activated water, and the ultra-low redox potential. The lowest in the water, it can remove free radicals very well.
• Antibacterial silver-loaded rear filter T33: Made of tropical rainforest coconut shell, with a large internal pore size, which can effectively inhibit bacteria, adsorb odor and pigment, and deeply treat organic and inorganic compounds, and use ions released by silver to eliminate the cold virus. And other pathogenic agents.
• UF ultrafiltration membrane: an asymmetric semi-permeable membrane made of ultra-micro-pore polymer material, which is hollow capillary-shaped, the wall of the tube compensates for micropores, and uses the tap water pressure as the power to separate the liquid by the pore size of the fine molecular membrane. The screening process, with a pore size of 100 nm, efficiently removes bacteria, viruses and heat sources.
• AT light wave energy conversion filter: According to the human infrared light wave absorption theory, the infrared light wave material with energy of 2-20um is used to act on the light wave heat effect generated by the water body, and stimulate the vibration energy level of the water molecule, thereby activating the biological macromolecular activity of the nucleic acid-protein and recovering The body functions and balances.
• High-energy high-magnetic double-loop long-process magnetization filter: Using bipolar double-sided high-magnetic re-magnetization magnetic steel technology, multiple times of magnetic line cutting is performed on closed-circulating liquid, and the high magnetic flux can reach 3000 Gauss. The small molecule of water is agglomerated, has magnetic memory, and maintains the activity of water for a long time, and is small molecule water that is not reduced.
Recommendation: If you are buying a best and cheap water purifier, it is recommended to first understand the two technologies of the household water purifier industry:
• Reverse Osmosis: Reverse osmosis is recognized as the safest and most scientific water treatment technology in the world. The water coming out through the reverse osmosis membrane is basically pure water, which is only water molecules, so it is the safest.
• Ultrafiltration. The filtration precision of ultrafiltration is inferior to that of reverse osmosis, but it is not pure water. Because the pore size of the ultrafiltration membrane is larger than that of reverse osmosis, some manufacturers have publicized that ultrafiltration water purifier is a water purifier that can retain minerals. In fact, it is light to avoid, since it is not pure water.

What are the functions of the water purifier?

In recent years, the issue of drinking water safety has gradually gained more attention.
Water Purifier
Consumer demand is also rising. The function of the water purifier is to effectively filter out rust, sand, colloid, and chemical chemicals such as residual chlorine, odor, color, and pesticide in the water. Moreover, it can effectively remove impurities such as bacteria, germs, toxins, and heavy metals in the water. Then,
Water Purifier
What is the role?
Common waters harmful to the human body include industrial wastewater, pesticide-contaminated water, heavy metal water, animal wastewater, etc.; common harmful substances in water include bacteria, viruses, E. coli, particulate impurities, and residual chlorine. The water purifier can also purify all the above toxic water, and the water purifier can remove the harmful substances contained in the above water. The mission of the top home water purifier is to purify the water, improve the water source, and install it in the kitchen to purify the tap water (groundwater). It can effectively remove harmful substances such as viruses, impurities, residual chlorine, and heavy metals in the water, and wash the vegetables, cook rice, and soak the fruits with purified water. It is very healthy and beneficial.
2, instead of barrel bottled water
The cost of bottled water is extremely high, which is not suitable for daily use by the family. Bottled water is listed as daily water by most wealthy families. However, this method is too high for consumption and is not suitable for large-scale use, and the effect may not be like a water purifier. The barreled water is connected to the water dispenser, which has a high cost, a short useful period and is more susceptible to secondary purification. A bucket of water is about 70 yuan, the cost is higher, and the water is tap water that is processed by a large water purifier or pure water. There are very few natural wells. A bucket of water is stored for a short period of time and is easy to change. It is in an open form after being connected with the water dispenser and will be purified by the purifying substance in the air.
3, the benefits of water purifier
(1) Making tea: There is no residual chlorine smell, and the tea is more fragrant and purer.
(2) Use hot water to make hot pot: the top is not bleached, the soup is positive, and the taste is purer.
(3)  Mung bean soup: 30 minutes of mung bean completely flowering, clear soup green water (cooked with tap water, mung bean soup red, red foam on it, and a long time).
(4) Cooking rice, steaming rice, making noodles, stir-fry: no more chlorine, the rice is more fragrant.
(5) Electric kettle boiling water: no water, no cleaning.
(6) Cleaning the ophthalmic lens: reduce scratches and be cleaner.
(7) Wash your face, wash your hands and take a bath: the skin is delicate and white, no longer greasy, saving time and detergent.
(8) Laundry and towels: no longer yellow or hard;
(9) Extend the service life of electric appliances: water heaters, washing machines, electric irons, humidifiers, etc.

What is a water purifier? What are the functions of the water purifier?

Water is the source of life. We have to drink water every day, so the quality of drinking water is closely related to our health. The function of the water purifier is to filter out floating objects such as heavy metals, bacteria, and viruses in the water. So, what is the water purifier? What are the functions of the water purifier? Let’s take a look at the knowledge of the water purifier!
How is the water purifier good?
1, the water has no pollutants
Common pollutants are mainly bacteria, viruses, heavy metals, organic matter, inorganic substances, cyanobacteria, red worms, colloids and so on. The main function of the water purifier is to filter out these harmful substances to ensure the safety of the water.
2, effectively remove residual chlorine
The main disinfection process in the waterworks is to make chlorine into the water, which is why tap water has the taste of bleach. Residual chlorine is not pollution. The country requires that the tap water to the household must contain chlorine. However, residual chlorine will produce carcinogen chloroform in the water, and the taste of the bleaching powder will also affect the taste of the water. In addition to the general form of residual chlorine in the water, the purifier is activated carbon adsorption, then the quality and service life of the activated carbon determines the adsorption effect.
3, no secondary pollution
Whether the water filtered by the water purifier can be drunk depends on whether the water purifier itself will cause pollution, so the choice of the material and filter material of the water purifier is particularly important. For example, as mentioned above, the quality of activated carbon has been exceeded by many domestic models of water purifiers. The main reason is the use of wood charcoal and coal charcoal. The activated carbon used in the water purifier is preferably coconut shell charcoal, which is processed from the coconut shell and is more expensive. In addition, some manufacturers promote their products with the addition of medical stone, which can increase the minerals in the water. This is nonsense. Products with such substances cannot pass the national quality inspection.
What are the functions of the water purifier?
1. Remove the sediment and rust from the water.
Most of the tap water comes from rivers, and there are naturally some river sands in the water. The wide-scale filtration of the water company is impossible to completely remove the sediment. The rust is derived from the oxidation of the tap water pipe, and the filter element of the water purifier filters out 0.01 UM of impurities, which can be completely filtered out through the water purifier.
2, remove organic pollution in water
Organic pollution in tap water is very serious in industrial cities, and these organic pollutions are quite harmful to the human body. The water company does not have such large equipment to remove this organic pollution, and the activated carbon adsorption filter of the household water purifier can completely remove the organic pollution.
3. Soften tap water and remove heavy metal ions from water
There are a lot of heavy metal ions in the tap water, and the human body ingests too much heavy metal, which will bring human life to life. RO reverse osmosis household water purifier can completely remove heavy metal ions in water and reduce the hardness of the water.
4. Remove bacteria from tap water
Due to the extensive filtration effect of the water company, it is difficult to ensure the filtration effect. Therefore, before using tap water, the tap water must be filtered through secondary filtration to completely remove all the bacteria.
5, remove chlorine from tap water
Water companies usually use chlorine gas in the water for disinfection and bleaching. However, chlorine itself is a toxic gas that dissolves in water and forms a health hazard. If a household water purifier is installed, the activated carbon adsorption filter in the water purifier can remove chlorine from the tap water to eliminate health hazards.
Water is very important to health. The contents of how the water purifier is good and what functions of the water purifier are introduced are introduced here. Friends who are interested in knowing may wish to refer to it, I hope to be helpful!

The role of the water purifier is to let you drink water at ease

Why do we recommend that every household should install the best and cheap water purifier? The household water purifier can help us drink healthy and pure water. So what is the problem with the tap water we usually drink? Or what is the problem with our drinking method? The following small series will explain to everyone.

Why can’t tap water be consumed directly?

Tap water residual chlorine problem

Throughout the history of tap water treatment in the world, whether it is the current European water treatment process or the traditional watercraft born in Belgium in 1902. The general process of the tap water treatment process is: raw water → through the water plant → through sedimentation (removal of algae, sediment) → filtration (removal of large particulate matter) → chlorination (sterilization) → finally enter the family through the tap water pipe.
This technique uses chlorine or chloride to sterilize water and ozone to deodorize it.
In summary, tap water may contain residual chlorine, which is the reason why tap water is not suitable for direct drinking.
Tap water organic compounds, heavy metal pollution risk

Why can’t tap water be consumed directly? Chlorinated water treatment can kill bacterial and viral microorganisms in water, but it does not filter out organic matter, compounds and heavy metals dissolved in water. On the contrary, residual chlorine reacts with some compounds in water to form A more harmful chlorinated compound.
Tap water pipeline secondary pollution risk

Why can’t tap water be consumed directly? In the process of tap water transportation, most of the water pipes used in the early stage are galvanized pipes or steel pipes, which is especially common in some old towns. The pipes are prone to rust after aging, resulting in high lead content, especially in places with welding, and secondary to tap water. Pollution. Although the state now requires the use of PP materials for tap water pipelines, it is still difficult to replace all the water pipes in time according to the actual situation in China. On the other hand, due to the long-term use of the pipeline, it will not be replaced, resulting in the adsorption of a large number of tiny particles on the inner wall, which will also cause secondary pollution of the tap water.

Is it necessary to install a reverse osmosis water machine?


The impact of common pollutants in the water on the human body
Lead: It is harmful to the kidneys and nervous system, and has high toxicity and carcinogenicity to children. Cadmium: Acute damage to the kidneys.
Arsenic: It is harmful to the skin, nervous system, etc., and carcinogenicity has been confirmed.
Mercury: It is very harmful to the human body. The main organs of injury are the kidney and the central nervous system. Selenium: High concentrations can harm the muscles and nervous system.
Nitrite: causes cardiovascular disease, the most obvious impact of infants (blue baby), carcinogenic.
Carbon tetrachloride (organic matter): It has a wide-ranging effect on human health, is carcinogenic, and has a great impact on liver and kidney function.
Trichloromethane (chloroform): Chloroform has the greatest impact on human health, and chloroform can be poisoned by inhalation, oral or skin contact. Chloroform is a stimulant that inhibits the central nervous system and the heart system and can cause toxicity to the liver and kidneys. In the literature, someone who ate 10 cc caused coma and death.

The role of reverse osmosis water purifier
The main function of the household reverse osmosis water purifier is to isolate the harmful microbial pathogens and heavy metal ions through the reverse osmosis process of the core component, RO reverse osmosis membrane and collect and supply the pure water for human consumption. The water from the reverse osmosis pure water machine can be directly consumed.
Summary: Water is the source of life. Although it does not directly make us feel the effect, it is actually used in our lives. Therefore, for the healthy life of family and oneself, please use healthy water.

What is the difference between a reverse osmosis water purifier and an ultrafiltration machine?

Posted on by

What is the difference between a reverse osmosis water purifier and an ultrafiltration machine?


The difference:
First, the principle of purification
First of all, although both water purifiers can purify impurities in water, the purification principle is not the same. RO reverse osmosis water purifier is equipped with RO reverse osmosis membrane. Under the action of pressure, water can pass through RO membrane. Those inorganic salts, heavy metal ions, bacteria, viruses, and other impurities will be blocked by reverse osmosis membranes.
The ultrafiltration water purifier purifies the water source through its internal ultrafiltration membrane. Under the pressure difference, the water source can pass through the membrane and filter the impurities.

Second, purification accuracy
The two water purifiers with different purification methods have different purification precisions according to different principles. There is a layer of RO membrane inside the RO reverse osmosis water purifier. The pore size of this membrane is as small as a nanometer, while the size is as small as the virus and bacteria, and its volume is also a thousand times that of the RO membrane. The RO membrane is basically only water, does not contain other elements, and the filtered water can be boiled or boiled.
The ultrafiltration water purifier has an ultrafiltration membrane inside. The pore size of this filter membrane ranges from 0.01 to 0.001 μm, which is an order of magnitude larger than that of the RO reverse osmosis water purifier. At the same time, ultrafiltration membranes not only allow water to pass through but also allow small, small molecules to pass through, such as some mineral elements.
Third, the filter results
RO reverse osmosis water purifier separates water and concentrated water under a certain pressure, which makes the water purifier not only need electricity but also produces a certain proportion of wastewater.
The ultrafiltration water purifier relies entirely on water pressure for adjustment, eliminating the need to plug in the power supply.

Reverse osmosis water purifier and ultrafiltration machine


Water is like breathing. Water is always an indispensable part of life. As the saying goes, “One side of water and soil raises one person” can see the important position of water in human life. How to get safe and healthy living water and drinking water? Everyone will definitely think of purchasing water purification equipment. Now the consumers on the market are favoring the reverse osmosis filtration RO water purifier and ultrafiltration water purifier. What are the differences between the two water purifiers? Many consumers are misunderstood when they buy. Here is the difference between the reverse osmosis water purifier and the ultrafiltration machine?

The ultrafiltration water purifier is a device that purifies water using ultrafiltration technology. The difference from other water purification equipment is that an ultrafiltration membrane is used in the equipment. At present, the ultrafiltration water purifiers on the market are generally directly connected to the water pipe, and the internal multi-stage filter element is used to remove impurities in the water and retain trace elements. The filter element of the household ultrafiltration water purifier is generally 4-grade filtration or 5-grade filtration. The first level of 5μm PP cotton filter removes large particles of impurities such as sediment, rust, and colloid in raw water; the second layer is granular activated carbon filter to remove odor, heterochromatic and residual chlorine in water; the third layer is precision compressed activated carbon filter, adsorption of residual chlorine, heterochromatic odor, small molecular organic matter, heavy metals and particulate impurities; the fourth layer is ultrafiltration membrane, removing bacteria, colloids, macromolecular organic matter, etc.; the fifth layer is the post-activated carbon filter, further adsorption, Remove odor and improve mouthfeel. In fact, whether it is 4-stage filtration or 5-level filtration, it is necessary to look at the accuracy of ultrafiltration membranes and the quality of filter cartridges at all levels.

Ultrafiltration purifier eliminates the need for pumps, no electricity consumption, no electrical safety problems; large water output, no wastewater, environmental protection, and energy-saving; retains minerals and trace elements in water, and tastes similar to bottled mineral water on the market; cheap price.

Even though the ultrafiltration purifier has a good purification ability, its shortcomings are also very troublesome. After the long-term use of the ultrafiltration purifier, there will be a secondary pollution problem at all levels of the filter element; the residual pollutants on the surface of the ultrafiltration membrane will affect the water output and purification capacity, and need to be cleaned in time; the hardness of the water cannot be reduced. If the hardness of the raw water is high, the container will be fouled after cooking; for the removal of chemical pollutants, if the raw water pollution is serious or a water supply special event occurs, it is difficult to ensure the safety of the purified water.

RO reverse osmosis pure water machine is a water purifier that uses RO reverse osmosis technology for water filtration. Because its output water is very pure, it is called RO reverse osmosis pure water machine.

RO water purifier is usually also a 5-stage filtration system. The first stage is a 5μm pore filter to remove tiny impurities such as sediment and rust in raw water. The second stage is a pre-particle carbon filter to remove odor and residual chlorine in the water. Organic matter, part of heavy metals, etc.; third-stage 1μm PP cotton or compressed activated carbon filter to further remove residual chlorine, odor, and tiny impurities; fourth-stage RO membrane to remove calcium and magnesium ions, bacteria, organic matter, inorganic substances, etc.; After the activated carbon, it can improve the taste. There is also a part of pure water to add a sixth layer of minerals, adding some beneficial mineral elements to the pure water.

RO reverse osmosis pure water machine effluent water quality is safe, can remove all kinds of harmful impurities in water, can cope with the special problem of water supply; can filter out metal ions in water, improve the problem of high water quality, daily cooking utensils will not be structured, and drink taste good.
