Before you choose to install a water filter, you need to understand the function of different types of water purifiers. They are an important criterion for you to choose a water purifier.
The pre-water filter can only filter out large particles that are generally visible to the naked eye, such as sediment, rust, bloodworms and other substances; the product structure is small and light, with a clear filtration accuracy (5, 50, 100), and a large flow rate. , It can discharge sewage, has a long service life of the filter element, and has a low failure rate. It can protect downstream equipment, such as high-end faucets from clogging, and less sediment in the water heater; it has limited functions and can only filter impurities that are greater than the set filtration accuracy, similar to yellow water. Black water, peculiar smell water, water alkali, scale, and heavy metals cannot be removed, because the filtering principle of sieving has a slight impact on the water pressure of the pipeline tap water.
The ultrafiltration water filter uses the hollow fiber membrane internal pressure or external pressure filtration technology, and the filtration pore size of the membrane reaches the nanometer level, so the filtration effect is much better than that of the pre-filter and PP cotton. Smaller bacteria, viruses, carbon black and other water-insoluble particulate matter can be intercepted and filtered; but it has no ability to remove organic pollution, chemical pollution, odor, pigment and other substances dissolved in water, resulting in poor taste after treatment of tap water .
The filtration accuracy of the reverse osmosis water filter reaches 0.5-10nm nanometers, which can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in the water; the filtration is more thorough, and the water produced by reverse osmosis and nanofiltration is clean, safe and tasteful Excellent; it can completely remove water alkali and scale, and the water purification effect is very obvious. If the water pollution is serious or the water quality is not clear, it is recommended to use this type of water purifier.

Before installing a water purifier, we must figure out what water pollution may be involved in the drinking water we usually drink.
1. Rust
Most of the water pipelines laid in cities use copper and cast iron pipes, and severe corrosion and rust will occur in more than ten years. Later, galvanized steel pipes are used, but they are not easy to oxidize and have a better anti-rust effect.
Excessive rust can easily cause excessive iron content, which will increase the burden on the kidneys and seriously affect human health.
2. Lead and other heavy metals
Many heavy metals such as lead will dissolve into the water during water transportation. Long-term drinking will increase the burden on the human liver and kidneys, and easily cause liver, kidney, heart, and nervous system diseases.
3. Residual chlorine
At present, the most economical and convenient way to sterilize tap water is to add chlorination. Chlorine has super oxidizing ability and can kill many kinds of bacteria.
Since it can be sterilized, it will naturally have a certain degree of toxicity. If a small amount of chlorine bleach is swallowed, it can irritate the esophagus, mouth, and throat and cause vomiting.
When you turn on the faucet, you can smell a pungent odor, which may be caused by too much chlorine in the water.

How to choose a water filter?
 What kind of water purifier is more suitable for me? Can the water from the water purifier be directly drunk? Is the water from the water purifier harmful to the human body?
Filter method
The filtration method of water filter is generally through physical retention, physical adsorption and other methods.
The water treatment method of the water purifier is purely physical and does not filter by chemical means.
The RO membrane reverse osmosis filtration accuracy commonly used in water purifiers is equivalent to one-800,000th of hair
The size of impurities in the water
The size of impurities in the water has been scientifically tested as follows:
·Bacteria 0.4~5 microns
·Virus 0.01-0.1 micron
·Antibiotic 0.001-0.01 micron
·Heavy metal 0.0005-0.005 microns
 Inorganic material 0.0002 to 0.0005 micron
·The molecular weight of organic matter is greater than 100
How effective is the filtering
How about the filtration accuracy of the water filter?
Bacteria removal rate: 99.9%
Organic matter removal rate: 99.7%
Heavy metal removal rate: 99.9%
Antibiotic removal rate: 99.9%
What are you worried about with such a removal rate?

A wise decision is to install a water filter. Are you still hesitating whether to install a water purifier for your home? Perhaps this article will give you some reasons.

1. Tap water is easily polluted by bacteria, viruses, heavy metals and other pollutants after being transported through pipelines. However, the chlorine method can only kill some bacteria in the water. The sediment, rust, heavy metals, volatile substances, etc. in the water are It cannot be solved by boiling water, so this method does not improve the quality of drinking water. However, the water filter can filter out all the pollutants and ensure the healthy drinking water of the family.

2. The water filter can effectively remove all kinds of pollutants in the water, such as heavy metals, residual chlorine, bacteria, viruses and other substances that are harmful to the human body. The purified water has good taste, strong activity and weak alkaline water quality, which is completely acceptable. Meet the needs of daily life.

3. Compared with bottled water, the cost of water filter is lower. The cost of drinking bottled water for a long time will be very high. Moreover, after the bottled water is opened, if it is not used up in time, it is easy to be affected by bacteria and viruses in the air. Secondary pollution, so there is not the most ideal drinking water program. And installing a water filter would be a good solution.

In the current drinking water environment, choosing bottled water or installing a water filter has become a family problem. This article will compare the advantages and disadvantages of bottled water and water filters, allowing you to make the best choice.
1. Bottled water has various water quality, various nutrition and various taste. Because the various brands of bottled water come from different regions; different regions have different water quality; different water quality will contain different nutrients; different nutrients will make the bottled water taste diverse, which can be used for consumption Provide more choices and drink the water that suits you. The installation of a water filter needs to be selected according to the water quality of the city, and it is best to choose a certified water filter.
2. The water filter needs to replace the filter element regularly. If too much foreign matter accumulates, it will cause secondary water pollution. Generally, the service life of the filter element is about six months, and the area with poor water quality needs to be replaced every three months. And high-quality bottled water does not have to worry about secondary pollution at all, because the bottled water will use fine filtration or ultrafiltration to remove harmful substances in the water during the production process, and the barrel will also be disinfected. But the cost of bottled water may be higher than the cost of the water filter.
3. The water filter is more convenient to drink. You don’t need to contact the bottled water company frequently. You need to buy bottled water in a few days. It usually takes about three to five years to buy a water purifier, and it usually only takes half a year or longer to replace the filter.
So compared to bottled water and water filter, water filter is better than bottled water.

The whole house water filtration system is an overall water treatment system that can treat domestic water and drinking water separately. This not only ensures the purity of drinking water at the entrance, but also the health of water for skin contact and equipment.
Although the quality of the water we drink from the water plant is basically guaranteed, when the tap water passes through various pipes, aging water pipes, rust-containing water towers, water tanks, etc. inevitably bring secondary pollution to the water. These will breed bacteria and contaminate drinking water. Again, although in order to eliminate these germs in the water, we have added chlorides to the water, and excessive chlorides can easily cause many diseases.
In addition to water pollution, water hardness is another indicator of water quality. Water hardness generally refers to the concentration of calcium and magnesium ions contained in the water. The main manifestation of hard water is that there are many impurities in the water, easy to form scale, heavy metals and disinfectant residues.
The hazards of hard water are manifold. In fact, the scale in the kettle is a direct manifestation of hard water. Faucets, sanitary ware, etc. are also prone to water stains and spots. Water heaters, floor heating, dishwashers, electric kettles and other electrical appliances will increase the accumulated scale due to the high content of calcium and magnesium ions in the hard water, resulting in a decrease in heat exchange efficiency. Secondly, in our daily laundry process, in order to achieve the same cleaning effect, hard water needs to use more detergents than soft water, and the clothes after washing are prone to become brittle and hard, which damages the life of the clothes. The more serious hazard of hard water is to affect health. In daily body and skin cleaning, hard water will give the skin a feeling of dryness and tightness due to high calcium and magnesium ions. For people with sensitive skin, hard water will bring more burden to the already sensitive skin. It is more likely to cause skin problems. Like skin cleansing, shampooing with hard water will also affect hair quality. In addition, hard water can cause harm to the health of the whole family. Hard water makes the skin no longer smooth and delicate, and makes the hair yellow and withered. What is more serious is that long-term consumption or use of hard water can greatly increase the incidence of various stone diseases in the body.
It is for the above reasons that more and more families choose kitchen water purifiers. However, a problem that everyone often overlooks is that drinking water purification is only the first step in healthy drinking water, and only whole house water filtration can completely solve the water quality problem. Why is whole house water purification so important?
The water purifiers we usually use can only solve drinking water, and the whole house water filtration breaks the net drinking water restriction of a single scene and equipment, and can provide clean drinking water solutions for all scenes such as drinking, eating, washing, and bathing. Other advantages of whole house water filtration include: whole house water filtration is a pretreatment of the whole house water, systematically intercepting residual chlorine, suspended solids, bacteria, viruses and other substances harmful to the human body in each water process. Therefore, the water purification effect is much stronger than that of a water purifier; the whole house water filtration has a larger output than a water purifier, which can meet more needs; the whole house water purification can be all over every corner of the house, compared to water purification Water for the device is more direct and convenient.

When you shower, some of the most common water hitchhikers aren’t doing your hair, skin, or overall health any favors. You need a body protected by a showr head filter.

People with sensitive skin
Showering with filtered water can reduce various skin conditions such as eczema, rash, dandruff and itchy scalp, so these filters are a wise choice for anyone who is prone to skin or scalp sensitivity, children, especially babies. The reason why showr head filters are beneficial to the skin is usually to remove chlorine, which is the cause of various skin irritation and skin dehydration.

Chlorine is especially irritating when warming, just like showering or bathing. Other water contaminants, such as dissolved minerals, can harden your hair, nails, and skin, strip off their natural oils, and make you fragile, itchy or dry. The shower water filter can also remove these pollutants and make you feel more comfortable.

People with asthma or other respiratory diseases
In addition to skin sensitivity, chlorine and certain dissolved minerals can also make asthma worse. When chlorinated or contaminated water is heated (used in showers or bathtubs), the problem reappears-this produces chlorinated vapor, which is exacerbated by inhalation.

People with compromised immune systems
The shower head may contain countless bacteria. Unless you are diligent in cleaning the shower head regularly, these bacteria will be atomized every time you shower. Regular cleaning will help, but the shower head filter can first prevent the accumulation of a large number of potentially harmful bacteria, thereby helping you stay healthy.

People who want to improve their overall hygiene
From the health of your lungs, eyes, skin, hair, etc., a showr head filter can refresh your self-care routine and make you feel softer and more moisturized. If you just want to enjoy a more pleasant shower or bathing experience, the showr head filter is a quick addition tool that can make a big impact.

The RO filter cartridge is the core component of the reverse osmosis system. The harmful substances in the water are completely intercepted by it. For this reason, the regular replacement of the filter cartridge is an important trivial matter for the families installed with the RO system. But with so many filter elements in the water purifier, how often does it take to replace it? But in fact, there is a signal before the RO filter cartridge needs to be replaced, so which signal reminds us to change the filter cartridge?

RO Filter Cartridge – PP Filter Cartridge
Remove sand, rust, small bugs, particulate impurities, and protect the filter cartridge behind.
Replacement period: 3-6 months
RO Filter Cartridge – Granular Activated Carbon Filter Cartridge
Absorb residual chlorine, chemicals, no-where odors and colors in the water.
Replacement cycle: 6-8 months
RO Filter Cartridge – Block Activated Carbon Filter Cartridge
Further remove large particles of impurities and no-where toner.
Replacement cycle: 6-8 months
RO Filter Cartridge – RO Membrane
The core filter element of the RO system mainly removes harmful substances such as arsenic, cadmium, lead and other heavy metals in the water, with a filtration accuracy of 0.001 microns.
Replacement cycle: 24 months
RO Filter Cartridge – Post Activated Carbon Filter Cartridge
Improve the taste of water and make the water more delicious.
Replacement period: 6-12 months
The filter cartridge is a simple separation device for purifying and separating the original fluid. It is currently used in air filtration, water filtration and other purification and filtration industries. The filter cartridge separates the solid particles in the liquid or gas, and is used to protect the normal operation of the equipment or the cleanness of the air.
With the popularization of all kinds of water purification knowledge, people have gradually realized that there is no ro filter without replacing the filter cartridge. As a consumable of ro ​​system, there is a certain life cycle, but when many people replace the ro filter cartridge, they feel that it is too expensive to replace it in time. So what harm will happen if the filter cartridge is not replaced in time?
1: Unable to purify water quality. When the RO filter cartridge reaches saturation, it cannot purify the water quality, thus affecting the water quality.
2: The water purification effect is weakened. Contaminants adhere to the surface of the RO filter cartridge and block the channels, resulting in a smaller water output and affecting water quality filtration. Incomplete filtration, there may be other harmful impurities in the water, long-term drinking is not beneficial to human health.
3: The water purifier becomes a “sewage device”. The filter element in the saturated state cannot inhibit the growth of bacteria in the water, and it is easy to make the water purifier a “hotbed” of bacteria and thus a “sewage tank”.
4: Overload work, gradual damage. The water purifier is filtered step by step. The function of the upper-level filter cartridge of the RO filter is weakened, which brings pressure to the next-level filter cartridge, causing the next-level filter element to overload and shorten its service life.

The replacement of the filter cartridge is so important, the following signals should be kept in mind before the replacement of the filter cartridge!
Signal 1: The water is too slow. In the case of the same water pressure and temperature, the RO system produces less water, indicating that the RO filter cartridge is likely to be clogged. At this time, it needs to be checked. If the filter element is really clogged, the filter cartridge needs to be replaced.
Signal 2: Water production is too fast. The water output of the water purifier is obviously accelerated. Generally, it may be caused by the damage of the RO membrane. At this time, the RO membrane needs to be replaced, otherwise the water purifier will completely lose its filtering function.
Signal 3: The taste of the water becomes worse. The RO system activated carbon filter element reaches saturation, which will cause the taste of the water to decrease. At this time, it reminds us that we need to replace the filter element quickly, otherwise the water purifier will become a “sewage device”.

A whole house water system allows you to have healthier and purer water. It will benefit your life.

Improve water quality, taste and smell-The entire house system guarantees to improve the water quality of the entire family by providing pollutant-free and odor-free water. For example, if you find sediment in the water and use a whole house sediment filter to treat your house, you will find that every tap has clean, clear water. The whole house sediment filter prevents dirt, sand and silt from clogging the pipes.

Extend the life of electrical appliances-whole house water systems are ideal for protecting your home from damage caused by various water contaminants. For example, if you encounter orange iron stains throughout your home, the whole house iron filter can remove these stains and protect your appliances by removing and preventing a large amount of scale buildup. Benefit from reduced red staining, rust particles and rotten egg smell. Improve the transparency and purity of water without any peculiar smell.

Improve health-Chlorine is a useful chemical used to treat tap water. Unfortunately, it is also a toxic chemical that is harmful to our skin and lungs. When we shower, heat opens our pores and absorbs chlorine from water and steam. The whole house carbon filter removes chlorine and provides chlorine-free showers, bathtubs and face washes for all faucets in the home.

Softer skin and hair-The whole house water softener is very beneficial to reduce the accumulation of scale in the whole family. This makes cleaning easier, hair and skin softer, clothes brighter and longer lasting. More importantly, it can prevent fouling of pipes and equipment and prevent any blockage from occurring. Due to the reduction of scale accumulation in hard water, water equipment can maximize efficiency.

A quick understanding of your water quality can help you decide if a shower water filter might be beneficial for you and your home:
Does your municipality use chlorine for treatment? And if so, how much?
Is your water hard?
You can generally find out how much chlorine is used in your communities’ water treatment online or by calling your local water board. You should also be able to access your water quality report online, which will tell you what kinds of contaminants are present in your water, and at what concentrations.
The bathroom is another important consideration when planning for your personal water experience. Showers, in particular, can cause problems if water is hard, or heavily treated with chemicals.

For example, cities commonly use chlorine to treat the water supply for bacteria and other contaminants, but this excess chlorine can be absorbed into the skin (sometimes in large quantities) when we’re showering, since most of us prefer to shower in warm water. The warmer the water, the more it opens pores, which effectively ushers chlorine (and any other water-borne contaminants that may be present in the water) right into the largest organ in our bodies —our skin.
Hot water can also cause any toxins, bacteria, or fungus in water to become airborne, turning a water-borne concern into a respiratory issue for some, especially those with already-compromised respiratory conditions like asthma.

How a Shower Water Filter Can Help
In addition to reducing chemical exposure when you shower, shower head filters can also improve your hair’s shine and feel, as well as support healthier, softer skin by minimizing contact with chemicals and toxins. If you choose a water filter that softens water as well, you’ll also notice that you need less soap, shampoo, and conditioner to get the job done as soft water helps very little product lather up quickly — saving you money with every single shower.  
Shower head filters can be useful even — and especially — if you live in a dorm, rental home, or apartment, or somewhere that already features water filtration. Not all water filters are created equal, so unless you’ve done the research to know exactly what kind of water filter your water is passing through, it may not make much difference when it comes to your general health, hair or skin care routine.
Softeners and filtration systems need to be serviced regularly to be effective, so if your landlord or property manager isn’t on top of the recommended maintenance, a shower head filter can be a great choice to ensure your shower is not only safe, but easier on your hair and skin. An extra bonus? Your shower will also be easier to clean, since shower head filters make it less likely water will leave unsightly or hard-to-remove hard water spots and residue on the shower and fixtures.
