Improve the water quality of household tap water

Tap water contains harmful substances such as scale, heavy metals, volatile substances and bacterial corpses, and home water filters can effectively remove various pollutants through physical filtration methods, and the outlet taste is good, which can effectively prevent harmful substances in tap water from harming the human body.

Replace barreled water

Many families will choose to buy bottled water, but ignore the high cost, short shelf life, and are susceptible to secondary pollution. After the bottled water is opened, the bacteria and other microorganisms in the water will multiply, and the bottled water cooperates with the water dispenser After use, it is in an open state, and harmful substances in the air can easily enter the inside of the bottled water through the water inlet, breeding a lot of bacteria.

Water quality is safe, convenient and economical

Home water filters can effectively remove bacteria, scale, heavy metals and other harmful substances in the water. The water quality is safe and clean. Of course, the home water filters mentioned here are water purifiers using RO reverse osmosis technology. pure water. In comparison, the cost of bottled water and bottled water is higher, and the bottled water industry is mixed, and the quality is difficult to distinguish.

Warning for home water filters

After the home water filters are installed, they will not be once and for all, because home water filter cartridges are consumables. When the filter time of the water filter is too long, the filtering effect will be slowly lost, so it is also important to replace the filter cartridges in time. . After all, there are many situations that affect the service life of home water filter cartridges, such as different drinking water volume, water stop, idle, etc. will affect the filter element.

Therefore, consumers need to pay attention to whether the quality of the purchased water filters is qualified before purchasing home water filters. When buying, they must choose regular merchants. Do n’t be greedy and buy low-quality water filter products, but it is easy to cause secondary Pollution.

Home water filters are also of great significance to consumers’ drinking water safety, but the water filter products currently on the market lack a lot in the sense of continuous safety. The most urgent needs of users are not only for a short time or a period of time. It is a long-lasting safety of drinking water.

You choose a home water filter. The first step is to confirm whether you choose an ultrafiltration water purifier or a reverse osmosis water filter. What is the difference between these two types of home water filters? Simply put, ultrafiltration water purifiers retain minerals, while reverse osmosis water purifiers are almost free of minerals.

Ultrafiltration Home Water Filter

Recommend friends who have low water hardness, no heavy pollution areas, and municipal water supply.

Reverse Osmosis Home Water Filter

Recommend the purchase of friends of heavy industrial cities and municipal water supply with high water hardness or serious pollution

The following points need to be considered when purchasing a home water filter:

1. What kind of water do you want to drink, pure water or mineral water?

2. Give yourself a budget.

3. Consider the cost of later use. When buying a water filter, don’t think that the system itself is very cheap. Just buy it. Replacement of the filter element in the later period may cause higher filter costs.

4. Convenience of later maintenance of water purifiers. Some home water filters may require professional personnel to replace the filter element for replacement. Not only need to pay the cost of the filter element, but also pay the on-site cost of employees. It is also a good idea to choose a machine that can easily replace the filter element yourself.

5. Purchase a certified home water filter.

Common problems with water quality
The water quality from the water plant is clean and can reach the standard for direct drinking. However, after long-distance pipeline transportation, due to the old and rusty pipeline, the urban high-rise water tank and the building group reservoir are not clean or are not disinfected all year round, which will cause secondary pollution.
Pollutant
Bacteria, viruses and algae reproduction
Chlorine and chloride
Sediment rust
Heavy metals such as lead and mercury
Radioactive material
Fertilizers and pesticides

Why is it necessary to install a whole house water filter?
Function: filter out all large particles of impurities such as sand, rust, insect eggs and so on.
Installation method: Install the whole house water filter at the main water pipe of the household.
Filtration standard: Filtration accuracy is usually around 40 microns
Post-maintenance: The pre-filter needs regular replacement of the water filter element, which needs regular replacement within 4-6 months.

Why is it necessary to install the kitchen RO system?
Function: The whole house water filter can only filter out large particles of impurities, while the kitchen water purifier also needs to filter out small particles of impurities such as odor, bacteria, pesticides.
There are two kinds of water used in the kitchen: one is vegetable washing water, and the other is direct drinking water.
Ordinary water filter: filters out bacteria, viruses, pesticides, etc., but retains calcium and magnesium ions. If it is boiled with a kettle, there will still be scale, which is what we usually call water containing trace elements. There is no need for electricity and no waste water.

RO system: filter out all impurities (including calcium and magnesium ions) in the water, it is soft water that can be directly consumed. There must be electricity and waste water.
Shower water filter
Main function: Turn hard water into soft water.
The difference between hard water and soft water lies in the mineral content of the water, which usually refers to the content of calcium and magnesium ion compounds in the water. The higher the content, the harder the water is, and the softer the conversely.

Reminder: Be sure to replace the water filter element in time

In fact, many consumers do not understand that contaminated water purifiers will breed bacteria to produce secondary pollution, and the quality of their purified water is not even as good as that of tap water.
If the household terminal water filter uses purified ro membrane to filter out pure water, the water filtered by the non-reverse osmosis type water purifier cannot guarantee qualified water quality. Moreover, the tap water contains high chlorine, and the water from the water purifier still contains chlorine. Only RO system can remove chlorine, so if you want to buy a water purifier, it is recommended that you choose a reverse osmosis water filter system.

The principle of reverse osmosis: when the same volume of dilute solution and concentrated liquid are placed on both sides of a container, and the middle is blocked by a semi-permeable membrane, the solvent in the dilute solution will naturally pass through the semi-permeable membrane and flow toward the concentrated solution The liquid level on the side of the concentrated solution will be higher than the liquid level of the dilute solution by a certain height, forming a pressure difference to achieve an osmotic equilibrium state. This pressure difference is the osmotic pressure. If a pressure greater than the osmotic pressure is applied on the concentrated solution side, the solvent in the concentrated solution will flow to the dilute solution. The flow direction of this solvent is opposite to the original infiltration direction. This process is called reverse osmosis.
Reasons for odor in water purifier
1. The service life of the filter element is up, there is no regular maintenance or replacement, the weather is hot, and the filtered bacteria, plant spores will ferment due to the increase in temperature, affecting the color and quality of the water.
2. If there is no one at home for a period of time, if it is not used, if the used filter element is stopped in the middle, when it is used again, it may cause fermentation pollution of the filter element due to interruption of use and affect water quality.
The technician reminded that the water purifier should regularly replace the filter element, and it is recommended to install an automatic water drain valve to automatically drain about 2 liters every 24 hours to simulate the state of use and maintain normal water flow to avoid water odors.

Water is the source of all things. Human life is inseparable from water. It is as important as air. In recent years, the industry has developed rapidly, and it has also aggravated the situation of water pollution. According to the World Health Organization of the World Health Organization, more than 2 million children worldwide suffer from diseases caused by water pollution every year. It is urgent to use drinking water safely and effectively. As an ordinary family, how to choose a suitable water filter system according to your own situation?

Why do We Need a Water Filter System?
According to reports, 80% of water pollution is caused by domestic sewage. Domestic sewage contains various toxins, solid waste, plastic garbage and bacterial pollutants. These toxic substances will be washed through the sewer or rainwater and flow into the ground to cause water pollution. Drinking water without sterilization is a common cause of diarrhea. Various bacteria in the water can also cause malaria, schistosomiasis and cholera. Most viral diseases such as hepatitis, polio and gastroenteritis are also caused by water pollution. Long-term use of drinking water with excessive heavy metals can also cause hair loss, liver cirrhosis, kidney failure and neurological disorders.
This shows that heavy metals, bacteria, and viruses in drinking water are the root cause of most water pollution diseases. Drinking water safety is of vital importance to human health.
The Principle of water filter system.
Choose a good water filter system first of all we need to understand its basic principles. water filter systems usually remove unwanted substances from water by screening, adsorption, ion exchange, etc. Different filters can remove harmful substances larger than its own pore size, and it can act on different harmful substances according to the filtering accuracy of the filter.
Common water filter system filters are as follows:

PP cotton water filter is used to remove all kinds of visible suspended matters such as dust, rust and sediment in water;
Activated carbon water filter is used to remove residual chlorine, absorb odors and colors in water and some organic matter;
Ultrafiltration water filters are less than 0.01 microns, used to remove bacteria, rust, colloids and other harmful substances in water, and retain the original trace elements and minerals
RO water filter system can intercept substances larger than 0.0001 microns, and can filter all components except water, including bacteria, viruses, suspended solids, metal ions, etc.

It is wise to install a whole house water filter, and one obvious benefit is to allow your entire household to be purified of water. Such as showers, faucets, laundry, watering flowers and so on. You need to understand some common sense of the whole house water filter cartridge, including their type, service life and function.

Types of Whole House Water Filter Cartridges

Generally speaking, the size of the whole house water filtration is fixed, and the common ones are 4.5×20 inch, 4.5×10 inch, 2.5×20 inch; they will also have different levels, there are first level, second level and third level. Many families will choose to install a three-level 4.5×20 inch whole house water filtration system. If you are considering what kind of whole house water filtration to install, three-level 4.5×20 inch may be a good choice. The whole house water filtration system needs regular replacement of water filter cartridges. More households will use PP sediment filter, GAC water filter cartridge and CTO water filter cartridge as their water purification core; of course, if your city ’s water quality is ph Too high, then you need to install a demineralized water filter element.

The Function of the Whole House Water Filter Cartridge

Each whole house water filter cartridge has its own function. There is rarely a middle water filter that can remove all pollutants in the water, which is mainly related to the complexity of the pollutants. Generally speaking, water pollutants include sediment, rust, bugs, chlorine, pigments, bacteria, antibiotics, compounds, etc. A whole house water filter cartridge removes one type of pollutants. PP sediment filter removes sedimentary pollutants in the water, including sediment, rust, small bugs; activated carbon water filtration removes chlorine, pigments and other pollutants in the water, the body surface filter is GAC water filter cartridge and CTO water filter cartridge.

The Service Life of the Whole House Water Filter Cartridges

Different types of whole-house water filter cartridges have their own service life. Generally speaking, the service life of sediment water filtration is 4-6 months; while the activated carbon filter cartridges are as long as 6-12 months. You need to judge the replacement cycle based on household water consumption and municipal water.

Reverse osmosis, commonly called RO, is the process of demineralizing water by flowing through a semi-permeable membrane under pressure.

If we think that pure water is to be produced from salt water, a “force” (pressure) must be applied in the salt water-containing column to force the water to flow in reverse so that water molecules flow through the semi-permeable membrane to the fresh water chamber.

Reverse osmosis can remove dissolved salts (ions), particles, colloids, organic matter, bacteria and pyrogens from water.

Reverse osmosis membranes repel pollutants based on their size and charge. Any contaminant with a molecular weight greater than 180 Da is most likely to be rejected by the normal operation of the reverse osmosis system.

In addition, the greater the ionic charge of the pollutant, the less likely it is to pass through the reverse osmosis membrane.

Reverse osmosis membranes will not remove gases such as CO2 or O2. These gases are not highly ionized (charged) when in solution, and have a very low molecular weight.

Water is electrically neutral, which means that when expressed in equivalents, the sum of cations is equal to the sum of anions. This also happens with RO permeate, and for each cation that passes through the membrane, the anion must also pass.The permeate is always electrically neutral and will maintain a charge balance.

Reverse osmosis applications

Reverse osmosis is very effective in treating brackish water (surface and ground), tap water and seawater, regardless of size.

Some application examples:

Municipal drinking water

Food and beverage industry

Agricultural irrigation

Industrial ultrapure water

Industrial process water

Wastewater reuse

Power industry (boiler feed water, cooling tower)

Municipal / industrial water reuse

Home use

You need to carefully consider whether to install the home water filter. This is very expensive if you purchase and install a home water filter as an experience. You spend more than just some money, and even include the health of you and your family. Before installing home water filter, you need to understand the 4 advantages of water filtration.

1. Solve the problem of secondary water pollution

You can’t live without tap water every day. Is the tap water as clean as it looks? Maybe it’s not what you think is different. There is no doubt that the water in the waterworks is clean. The only drawback is that it contains chlorine. Water plants use chlorine to kill bacteria in the water. Chlorine inevitably exists in tap water. The harm of chlorine may be more serious than you think. One of the best ways to remove chlorine is to install a home water filter. The activated carbon water filter in the home water filter can effectively remove the chlorine in the water. Perhaps another matter is more worthy of your attention. The tap water will be contaminated through the pipeline, and the tap water that reaches your home contains pollutants that you can’t see. Installing a home water filter allows you to say goodbye to secondary pollution.

2. Replace expensive bottled water

Maybe you are still buying expensive bottled water, which is a waste of water. Bottled water is not only expensive, but you need to drink it in a short time, because they can easily breed bacteria.

3. Tap water meets the standard of direct drinking

One advantage of installing a home water filter is that you can drink tap water directly, which is a convenient thing.

4. Low cost

You only need to spend a little money to buy a home water filter, you can drink clean water for unlimited times, and no longer have to worry about buying expensive bottled water.

It is necessary to keep you healthy with fresh air and safe water . An air purifier allows you to breathe fresh air; if you install a home water filter that allows you to drink clean and healthy water, then you better buy a home water filter.

You may have had such an experience. When you go home for a trip, the colored water flows out when you open the faucet. This is because it contains rust, sand and bacteria. Why is the tap water so dirty? The water plant will have water purification equipment, so the water should be clean. However, due to the aging of the transportation pipeline, it will cause secondary pollution of the tap water. Even if the tap water that normally looks clean may have been polluted. So installing a home water filter can keep you away from the trouble of tap water being contaminated by secondary water.

Can the clear water drink? Clear water will give you the illusion that it is clean. This is because your eyes do not have the function of a microscope. There may be a lot of harmful substances such as bacteria, antibiotics, and compounds in tap water that looks clean. There is no better way to remove these harmful substances than buying a home water filter.

Will bottled water be a better choice? Not really. The large-capacity bottled water that you usually buy requires you to drink it quickly in a short time. This is because the opened bottled water can easily breed a large number of bacteria, which can easily threaten our health. Install a home water filter, it will allow you to drink safe and healthy water at any time.

What kind of home water filter to buy and install? There are many water purification products on the market, which require you to buy according to your family’s situation. What you need to know is the running water situation in your city and the number of people in your family. Generally speaking, the whole house water filter is a simple way, it can make all your household water can be purified. Another ro system is also a good choice. RO system can ensure that your drinking water feels safe, after all, it is currently the most advanced water filtration product.

How to buy and install home water filter? A simple way is to purchase a water filter with third-party certification. This is the best way to buy a high-quality home water filter quickly.

Everyone want the water in your kitchen faucet to be clean, but it may contain contaminants, some of which may be harmful to your health. Well, it’s no wonder that almost half of Americans say they first filter or boil water when drinking tap water at home. According to Consumer Reports’ 2019 Water Quality Survey, the survey is based on a sample of 4,225 U.S. adults representing the nation.

The biggest complaint about drinking water is the unpleasant taste and smell. The survey also shows that in addition to the water filters built into many refrigerators, water filter pitchers are also the type most people use.

The water filter pitcher is definitely easy to use. Just fill the faucet water in it and wait for the water filter cartridge to filter the water. They are also relatively cheap, usually less than $ 40.

1. Target pollutants

Whether the quality of the filter is certified by the NSF / ANSI standard is a good indicator to measure the quality of the filter. The standard measures the ability of the filter to remove certain pollutants. Another indicator to note is whether the company is a member of the Water Quality Association (WQA).

The design of most water filter pitchers only improves the aesthetic aspects (taste and smell) of drinking water. One of the best is to find a certification body that has obtained NSF / ANSI 42 certification, not every pitcher can do it.

On the other hand, if you want to remove certain harmful contaminants, such as heavy metals, make sure that the filter has passed NSF / ANSI 53 certification. However, it is difficult to find NSF / ANSI 53 certified filters of this size. If your household water contains serious contaminants, you may need to focus on a larger, more advanced filtration system.
