1. Zeolites: Stilbite, a type of natural zeolite, features high crystallinity and an open pore system. Its crystal structure contains numerous open pores and channels of varying sizes occupied by cations and water molecules. The water molecules in the channels can reversibly adsorb and desorb fluoride without damaging the zeolite’s crystal structure. Under ideal conditions, it can reduce fluoride levels to below 1 mg/L.

2. Bone char: Derived from animal bones and transformed into a type of carbon, bone char has a carbon structure with a large surface area and excellent adsorption properties. The hydroxyapatite in bone char adsorbs fluoride ions in water, forming calcium fluoride, thereby achieving fluoride removal. The fluoride removal capacity of bone char is 1.68 mg/g, and its effectiveness is influenced by various factors, including the original fluoride ion concentration, bone char particle size, pH, water temperature, and the presence of other ions in the water. Under ideal conditions, it can reduce fluoride by about 70%. However, bone char is not favored by vegetarians.

3. Ion exchange media: Many ion exchange media are specifically designed for industrial applications. Although there are specific ion exchange resins for fluoride removal, there is a risk of fluoride leakage when these resins become saturated.

4. Activated alumina: Activated alumina is an inorganic material with strong fluoride adsorption capacity and the ability to catalyze fluoridation reactions. It can remove fluoride from water through a chemical reaction between fluoride ions and the surface of aluminum oxide.

5. Reverse osmosis membrane technology: If the sole purpose is to remove fluoride, reverse osmosis membrane technology is also an option. However, the removal rate is related to the fluoride concentration in the water, pH, and the material of the reverse osmosis membrane.

Each of these methods has its advantages and disadvantages. When treating fluoride in water, it is necessary to select the appropriate method based on the specific circumstances to achieve the best results.

Hydrogen-rich water is just normal water with hydrogen gas dissolving in it.

2. Why drink hydrogen-rich water?

Hydrogen water acts a powerful antioxidant that can neutralize harmful free radicals and protect your cells from oxidative stress. Hydrogen water has many potential health benefits, such as improving hydration, reducing inflammation, enhancing energy, boosting immunity, and preventing chronic diseases.

3. Is there any side effects of hydrogen water?

No, no side effects have been found.

4. How often should I drink hydrogen water?

You can drink it everyday.

5. What are the differences between hydrogen antioxidants and vitamin C ?

Both hydrogen and vitamin C can act as antioxidants, but the free radicals produced by the body can be divided into two categories: one type is needed by the body, and the other type is unnecessary and highly toxic. Vitamin C “treats” all free radicals the same and eliminates them all; hydrogen only eliminates the unnecessary and highly toxic free radicals, such as hydroxyl radicals. This means that no matter how much hydrogen is supplemented, it will not affect the normal functions of the body. However, if vitamin C is supplemented in large amounts, it may affect normal body activities.

6. Can hydrogen reach the brain and function?

Hydrogen is a very small and flexible gas molecule that can freely reach all parts of the body. Many drugs are blocked by the blood-brain barrier, but hydrogen can pass through this barrier and reach the brain, where it is found in high concentrations. This is one of the main reasons why hydrogen has the potential to be a safe and effective treatment for Alzheimer’s disease and other neurodegenerative disorders.

7. How do people generally intake hydrogen gas? Which method is the best?

People can intake hydrogen gas through drinking hydrogen-rich water, inhaling hydrogen gas, and taking baths in hydrogen-rich water, which allows for absorption through the digestive system, respiratory system, and skin. Drinking hydrogen water is the most convenient method, mainly focusing on improving digestive tract and metabolic issues. Inhaling hydrogen gas is primarily aimed at improving lung and tracheal problems. Taking a bath in hydrogen-rich water is focused on improving skin issues and is beneficial for anti-wrinkle and beauty purposes.

8. When drinking hydrogen water, can hydrogen gas be absorbed from the digestive tract? How is it absorbed?

Gases can indeed be absorbed from the digestive tract, which is in accordance with the law of material diffusion. Gases dissolve in liquids or water, and this is fundamentally no different from the dissolution of other substances such as glucose or salt. Glucose can be absorbed by the digestive tract, and gases can also be absorbed, both through diffusion from areas of higher concentration to areas of lower concentration.

9. What are the intuitive experiences of drinking hydrogen water?

Many people report an improvement in energy levels compared to before, and a reduction in the degree of physical fatigue. Additionally, there is a noticeable decrease in the frequency of colds and fevers, and even when a cold does occur, the symptoms are significantly alleviated. There is also an improvement in appetite, and gastrointestinal issues such as diarrhea and abdominal pain are relieved.

10. Does hydrogen play a role in anti-aging?

Experimental studies have demonstrated that the lifespan of nematodes can be extended several times in a hydrogen-rich environment. Long-term consumption of hydrogen-rich water can comprehensively improve health levels, alleviate sub-health symptoms, which is helpful for a longer life.

11. How is the most effective way to drink hydrogen water?

In clinical hydrogen medicine research, the general recommendation is to intake 1-3 milligrams of hydrogen gas per day, which is equivalent to 1000-2000 milliliters of saturated hydrogen water.

12. When is the best time to drink hydrogen water?

There is no hard and fast rule, just follow your daily drinking pattern.

13. Can drinking hydrogen water reduce fatigue?

Research has found that drinking hydrogen water can reduce athletes’ sports fatigue. It is recommended to drink it before and after sports and exercise.

14. Will drinking hydrogen water cause dependence?

Hydrogen helps improve the body’s health by adjusting the state of cells. It has no effect on normal cells. Therefore, drinking hydrogen water is not addictive, and there will be no discomfort when you stop drinking it.

15. Can hydrogen water be left for a while before drinking?

Hydrogen gas is particularly prone to escaping from water. The concentration of hydrogen in hydrogen water prepared by conventional methods decreases rapidly. However, the concentration in hydrogen water prepared using nanotechnology decreases more slowly. Therefore, it is better to drink hydrogen water as soon as possible after it has been prepared using a hydrogen water cup or a hydrogen water generator.

16. Is it possible to carry hydrogen water in a glass bottle?

Hydrogen gas is extremely permeable, and it can pass through ordinary plastics, glass, and even stainless steel, which are unable to contain it. Hydrogen water can only be kept at a certain concentration for a period of time if it is stored in a sealed container made of aluminum alloy.

17. What advantages does hydrogen have over other health supplements?

Hydrogen has a good safety profile, with no dosage limitations, and there have been no observed adverse reactions to date, so it can be used with confidence. The use of hydrogen is simple and convenient; by simply replacing our regular drinking water with hydrogen water, we can protect our health. The cost of using hydrogen is low, and long-term application will not impose a financial burden on the family.

18. Can hydrogen gas replace medication?

No, hydrogen gas should only be used as a supplementary means for bodily conditioning. Any issues related to diseases and medications should be consulted with your professional doctor.

Powdered Activated Carbon (PAC)：

Powdered activated carbon is actually granular activated carbon with a finer particle size. Due to its small particle size and large surface area, its adsorption effect is superior to that of the commonly used granular activated carbon.

Granular Activated Carbon (GAC)：

This is the most commonly used type of activated carbon in water purifiers. The smaller the particles, the better the adsorption effect, but the greater the water resistance (inlet and outlet pressure difference), and there is also a higher risk of carbon leakage. Therefore, water purifier manufacturers should choose granules of the appropriate size. In large-scale water treatment equipment, 10 to 24 mesh (Φ2.0 to 0.8mm) is commonly used, while for small household water purifiers, due to the short height of the carbon column, fast flow rate, and short contact time between water and activated carbon, it is recommended to use 16 to 32 mesh (Φ1.3 to 0.6mm).

Activated Carbon Fiber Felt (ACF)：

The most significant characteristic of ACF is its large specific surface area and abundance of micropores, with the volume of micropores accounting for over 90% of the total pore volume. The micropores are small in diameter and open directly onto the fiber surface, which results in a high adsorption capacity, high adsorption efficiency, and rapid adsorption and desorption rates.

Yucheng Technology’s Aroma Shower Filter uses ACF imported from Japan, with a surface area of 2500m2/g, to quickly filter out various oxidants from tap water, such as bleach; significantly enhancing skin hydration effects and alleviating various skin issues.

Sintered Activated Carbon Filter Cartridge (CTO)：

Sintered Activated Carbon Filter Cartridge (CTO), also known as carbon block filter cartridge or compressed activated carbon filter cartridge. It is formed by heating and extruding granular activated carbon into shape. The outer layer of the carbon core is often wrapped with white polypropylene (PP) non-woven fabric. The sintered activated carbon filter cartridge combines both adsorption and filtration functions (average pore size 3 to 20 micrometers),but its filtration function is general lower than that of PP melt-blown filter cartridges, and its adsorption function is lower than that of granular activated carbon filter cartridges.

For water purifiers, the corresponding activated carbon should be selected according to the actual needs of the product to achieve optimal performance.

Well, the market is flooded with activated carbon of varying qualities. The prices of these different qualities vary significantly, and of course, so do their effect. When purchasing a water purifier with an activated carbon filter, it is essential to choose high-quality activated carbon with good efficacy to ensure the effectiveness of the water purifier. Below are some typers of Low-quality &cheap carbon particles.

These types of carbon are cheap. It contains a lot of ash and carbon fines, which generate significant dust during production, processing, and transportation. Additionally, its performance and taste are not good.

In Yucheng’s water purifiers, we use the HAYCARB brand coconut shell activated carbon imported from Sri Lanka. It is certified by NSF and comes with dust removal inspection reports, Quality Assurance Certificate. Additionally, it has the health permit approval for products involving drinking water hygiene and safety, that’s why the water from our water purifiers is hygienic, clean and tastes very good. Below are two documents of our activated carbon, feel free to contact us for more documents.

KDF is a high-purity copper-zinc alloy, a new type of water filtration medium invented by Dr. Don Heskett in 1984 in the United States. The principle of water purification is based on redox reactions, where the KDF medium exchanges electrons with pollutants, transforming many contaminants into harmless substances. KDF particles are particularly effective in removing chlorine and water-soluble heavy metals from water. They can effectively remove chlorine, organic compounds, heavy metals, and prevent the formation of carcinogenic substances like trihalomethanes, making the water safe and potable.
KDF material has a strong reactivity and extremely fast reaction speed in water, capable of eliminating up to 99% of chlorine and dissolved metals such as lead, mercury, nickel, and chromium ions and compounds. It is also highly effective in inhibiting the growth of bacteria, fungi, algae, and scale. It is used in pretreatment, primary treatment, and wastewater treatment equipment. KDF can enhance or replace existing technologies, significantly extending system life, reducing heavy metals, microorganisms, and scale, lowering overall costs, and simplifying system maintenance—hence it is known as “water gold.”

2. Amino acid scale inhibitor

Yucheng Technology’s Anti-scaling pre-filter and Aroma Shower Filter use an amino acid scale inhibitor, which is primarily made from malic acid extracted from crushed fruit peels and other natural sources. This food-grade particulate material is synthesized through pharmaceutical processes and slowly releases effective scale-inhibiting factors upon contact with water. These factors combine with calcium and magnesium ions, neutralizing their charge so that they no longer attract carbonate ions, thereby reducing the formation of scale.

3.Calcium sulfite

Calcium sulfite balls are primarily used to remove residual chlorine from water. They can eliminate 99% of residual chlorine in just 0.8 seconds. Compared to traditional activated carbon for chlorine removal, calcium sulfite offers advantages such as high efficiency, safety, high-temperature resistance, and does not promote bacterial growth. Made from natural materials like calcium sulfite through a special proportioning of characteristics and fired with a rapid process, these balls are a high-tech water treatment product that combines biological and physical science technologies. They can instantly and effectively remove residual chlorine from water, purifying and mineralizing the water quality.

Ultrafiltration (UF) membrane is a type of filtration membrane with pore sizes smaller than 0.01 micrometers. It is composed of numerous ultrafiltration membrane fibers. On a one-meter-long ultrafiltration membrane fiber, there are approximately 6 billion pores, each 0.01 micrometers in size. The 0.01-micrometer pore size can filter out most harmful substances, such as silt, rust, suspended particles, colloids, large organic molecules, microbes, bacteria, etc., while also retaining the minerals and trace elements in the water.

In the field of household water purifiers, hollow fiber ultrafiltration membranes are widely used in end-point water purification due to their high packing density, large effective area, high water throughput, simple operation, and ease of cleaning. When water enters the ultrafiltration membrane, under the action of water pressure, purified water permeates through the walls of the ultrafiltration membrane tubes. Impurities in the source water, such as bacteria, rust, and colloids, are trapped, achieving the purification process. The pore size only allows water molecules, beneficial minerals, and trace elements to pass through, thereby retaining the minerals and trace elements beneficial to the human body.

RO membrane:

RO membrane, or Reverse Osmosis membrane, operates on a principle that is counterintuitive to natural osmosis. Normally, water moves from an area of low solute concentration to an area of high solute concentration. However, when pressure is applied to the water, it flows from a higher concentration to a lower concentration—this is the principle of reverse osmosis. The pore size of an RO membrane is incredibly small, about one-millionth the diameter of a human hair (0.0001 micrometers), which is invisible to the naked eye. Bacteria and viruses are about 5,000 times larger than the pores, so they, along with other impurities and heavy metals, are flushed away in the waste water stream. Only water molecules and some mineral ions can pass through the RO membrane.

The working principle of an RO membrane involves applying pressure that is higher than the osmotic pressure, allowing water molecules and other small molecules to pass through the reverse osmosis membrane while blocking other impurities and pollutants. This process achieves water separation and purification.

RO membranes are widely used in the field of water treatment, including desalination of seawater, desalting of brackish water, and purification of industrial water. They can effectively remove most impurities and pollutants from the source water, allowing only water molecules and other small polar solute molecules to pass through, thus producing purified water.

Absolutely, you’ve got the key differences down:
Ultrafiltration (UF) membranes are known for their fast water output and high flow rates. They operate on the principle of physical filtration without producing any wastewater, which is a significant advantage in terms of water conservation. UF membranes can effectively remove many types of contaminants, including bacteria and suspended solids, while retaining beneficial minerals in the water.

On the other hand, Reverse Osmosis (RO) membranes offer a higher level of filtration precision, capable of removing not only bacteria and suspended solids but also viruses, heavy metals, and even dissolved salts. This makes RO-treated water extremely pure. However, the process is slower and produces a lower water yield. Additionally, RO systems generate wastewater, RO systems are generally more expensive than UF systems, both in terms of initial investment and maintenance costs.

Choosing between UF and RO systems depends on the specific needs and water quality requirements. If the goal is to have highly purified water and the removal of dissolved contaminants is a priority, an RO system would be the better choice despite its higher cost and wastewater production. If the water source is relatively clean, a UF system would be sufficient and more cost-effective.

The PP cotton filter cartridge is made of polypropylene, which relies on the self-adhesion of polypropylene fibers to entangle with each other, without the need for other materials for bonding, ensuring a clean and safe chemical composition. It adopts a multi-layer gradient structure, with coarser fibers on the outer layer and finer fibers on the inner layer; the outer layer is relatively loose, while the inner layer is tight. This multi-layer gradient structure allows each layer of the PP cotton filter cartridge to intercept and store impurities in the water, naturally resulting in a large dirt holding capacity. Additionally, the three-dimensional curved path micropore structure of the PP cotton filter cartridge provides a larger surface area and higher porosity. The large surface area and numerous small pores allow water to pass through the PP cotton quickly, increasing the filtration flow rate.

Most household water purifiers choose PP cotton filter cartridges for the first stage of filtration, filtering out over 80% of impurities in the water. The PP cotton filter cartridge not only directly affects the water quality but also impacts the effectiveness and lifespan of the subsequent second, third, or fourth stages of filtration, making it particularly important for water purifiers. Yu Cheng Technology uses industry high-quality PP cotton filter cartridges with a relatively high fiber density for all its filters.

The filtration precision of PP cotton filter cartridges used in households is generally between 1~5μm, designed to intercept large particulate impurities, such as suspended solids, silt, rust, etc., in the water. In areas with poor water quality, the PP cotton filter may need to be replaced every 2-3 months, while in areas with good water quality, it generally lasts six months. Therefore, if the household water purifier you purchase includes a PP cotton filter cartridge, it is recommended to replace the filter cartridge every 3-6 months depending on the local water quality.

Ceramic Filter Cartridge:

The ceramic filter cartridge is a new type of eco-friendly filter made from ceramic. Its pore size is 0.1μm. It is primarily used for filtering, antibacterial treatment, and activation of drinking water. It removes silt, rust, harmful residual chlorine, and suspended pollutants, organic chemicals, color, and odors from the water while retaining beneficial minerals.

Ceramic filter is a far more environmentally friendly option than relying on bottled water and significantly cheaper than many other filtration systems. The ceramic filter itself can be cleaned and reused.

Both PP cotton and ceramic filter cartridges are commonly used as the first stage filter in household water purifiers, and the choice between them can be made based on local water quality conditions and practical needs. For instance, if the local water quality is poor, it is recommended to choose a PP cotton filter cartridge for the first stage of filtration because it can handle a larger volume of impurities without getting clogged as quickly as ceramic filters, which have smaller pores and higher filtration precision. On the other hand, if the local water quality is good, a ceramic filter cartridge can be chosen for the first stage due to its higher filtration precision compared to PP cotton. Additionally, ceramic cartridges can be cleaned and reused multiple times, offering a longer service life.

Molecular Hydrogen, or Hydrogen Antioxidant molecules (H2-), has unique properties to be able to enter cells and fight free-radicals where no other antioxidant can. This is
particularly beneficial for diabetics, because they have so many complications related to free-radical damage caused by their diabetes. The facts are that ionized water, rich in Hydrogen gas, has been used with great success by diabetics. Does it offer a cure? Not in the sense that it will repair islet cells, but it offers prevention to many conditions caused by free-radicals which are threatening and plaguing diabetics.

How do Free Radicals form?

Free radicals may form spontaneously or they may be the result of exposure to heat,
light or something in the environment: pollutants or toxins such as cigarette smoke,
drugs, alcohol or pesticides. Sometimes the body’s immune system creates them on
purpose to neutralize viruses and bacteria.

In the human body, we have a vast array of molecules that are more susceptible to free radical attacks than others. These include fats, DNA, RNA, cellular membranes, proteins, vitamins and carbohydrates.

Negative effect caused by Toxic Free Radicals.

● Toxic free radicals break lysosomal membrane. Histamine leaks out.
● Free radicals breaking nuclear membrane altering DNA(genetic) material.Toxic free radicals attack cell membrane from inside and create easy entry for destructive enzymes and pollutants.

Effects on Your Health：

While a low level of iron isn’t harmful in and of itself, iron in drinking water is classified as a secondary contaminant according to the EPA.This is because iron often carries with it bacteria that feed off the iron to survive. These tiny organisms can be harmful when digested.
In addition, if your iron levels are too high, serious health effects can develop, including iron overload. Iron overload is caused by a mutation in the gene that digests iron. Iron overload can lead to hemochromatosis, which can lead to liver, heart, and pancreatic damage, as well as diabetes. Early symptoms include fatigue, weight loss, and joint pain.
Excessive iron is never recommended for digestion; it can lead to stomach problems, nausea, vomiting, and other issues.

Effects on Your Skin:

Water with excessive amounts of dissolved minerals such as iron and magnesium can have negative effects on your skin. They can damage healthy skin cells, which can lead to wrinkles.

In addition, water with iron doesn’t blend well with soap. This causes issues when showering and bathing, as soap scum residue will be left not only in your bathtub but on your skin as well. This can clog skin pores, which will lead to a buildup of oils in your skin. This, in turn, can lead to skin problems such as acne or eczema.

Effects on Food and Drink:

Water with iron has a metallic taste to it, which makes it very unpleasant to drink. Using this water for beverages such as coffee or tea will create to an unpleasant and dark concoction.
In addition, water with high levels of iron is not recommended for your cooking needs. Vegetables and other foods cooked in such water will blacken and absorb a bad taste.
