What kind of water purifier should be used for household use? Is it better to use a household water

The surface of the sprayed parts and plastic parts of the water dispenser should be smooth and flat, uniform in color and luster, and firm in coating, and there should be no cracks, scratches, blisters, leakage spray, deformation and other defects. The water dispenser is filled with buckets, which can withstand impact and pressure without deformation. If the faucet does not open, the bucket water level should not drop, and the faucet does not drip.

After turning on the faucet, the water should be smooth and there should be bubbles rising in the bucket. The bucket should be easy to disassemble. The switch control button should be sensitive, correct and reliable.

After the power is turned on, each indicator should be displayed normally, after the refrigeration and heating display are extinguished, the temperature of the cold water released should be 5 10, and the hot water should be more than 85, the more water released, the better its performance is proved. Whether it has and is equipped with anti-secondary pollution technology and measures, good brand water dispensers have anti-secondary pollution devices. Safety performance When consumers buy, they should first identify the brand of the product and the CCEE product certification mark of the China Electrical Safety Certification Committee.

The selection of materials is mainly reflected in the cold and hot water buckets for water, the pipeline materials in contact with water and the faucets. If the manufacturer chooses low-quality stainless steel processing cold and hot water barrels and pipelines in contact with water, it will cause material corrosion and water pollution after a long time. The appearance surface should be smooth and flat, uniform color, firm coating, there should be no cracks, scratches, blistering, deformation and other defects, the joints are evenly connected, and all kinds of signs are clear and complete.

The performance of the whole machine The water dispenser is placed with a full bucket to ensure that the machine is not deformed with the impact and pressure of the full bucket. After turning on the faucet, the water comes out smoothly and there are bubbles rising in the bucket. After the power is turned on, the indicators are displayed normally, after the refrigeration and heating display are extinguished respectively, the temperature of the cold water released is 5-10, the hot water is more than 85, and the more water is released, the better its performance.

Kangdi water purification is OK, the quality is reliable, the factory sells directly, the material has nothing to say, and the after-sales service has nothing to say.

1. Is it better to have a water purifier or a water purifier?

Water purifiers. The main function of the water purifier is: to remove harmful substances such as residual chlorine, impurities, odors and bacteria in the water, to filter out impurities, rust, some bacteria, viruses, colloids, etc. in the tap water.

And the cost is much lower than that of bottled water, and the water tastes good and can be drunk directly. It has a large water yield, can be used for cooking rice and soup, which is convenient and fast, and can be prepared and drunk without waiting, so it is the most ideal drinking water solution for families.

Water purifiers. The water purifier can also improve the tap water, the water purifier uses water purification technology, which can completely filter these harmful substances and retain the minerals and trace elements needed by the human body. Therefore, it is necessary to install a water purifier to solve the scale of tap water, heavy metals, volatile substances and bacterial corpses, but the cost is high.

2. Classification of household water purifiers.

1. Pre-filter.

The pre-filter can filter out large particles of impurities that are generally visible to the naked eye, such as sediment, rust, bloodworms and other substances. The structure of the product is small and lightweight, and there is a clear filtration accuracy) The flow rate is large; It can be drained, the filter element has a long service life, and the failure rate is low. It can protect downstream equipment, such as high-grade faucets without clogging, water heater liner with less sediment, etc.

2. Ultrafiltration membrane filtration.

Because the ultrafiltration membrane adopts hollow fiber membrane internal pressure or external pressure filtration technology, the filtration pore size accuracy of the membrane reaches the nanometer level, so the filtration effect is much better than that of the pre-filter and PP cotton, which can not only filter out the above substances, but also smaller bacteria, viruses, carbon black and other water-insoluble particulate matter can be intercepted and filtered.

3. Reverse osmosis membranes.

The membrane materials currently used are mainly cellulose acetate and aromatic polyamides. Its components are hollow fiber, roll, plate and frame and tube. It can be used for separation, concentration, purification and other chemical unit operations, with higher filtration precision, and is mainly used in civil pure water preparation and seawater desalination industry.

3. Installation of water purifier.

1. Turn off the main switch of tap water.

Before the water purifier is installed, it is necessary to turn off the main switch of tap water, install stainless steel tee and ball valve at the position of water intake, and then connect the water inlet of the water purifier with a PE pipe and connect the flushing port with a PE pipe of about 15 cm.

2. Install the sealed ultrafiltration element.

When the water purifier is installed, the sealed ultrafiltration element in the accessories must be taken out in the fifth-stage ultrafiltration device, installed on the ultrafiltration device, and fixed with an old-fashioned board.

3. Start rinsing.

Check and turn off the refrigeration and heating switch, plug in the power supply and start flushing, and close the ball valve after there is no black water at the flushing port.

4. Rinse the hot and cold water bucket.

Open the bottom drain (soft plug + nut cap) of the hot and cold water bucket and rinse it for 25-30 minutes until there is no small white foam in the water.

5. Tighten the screw cap.

Tighten the drain nut, turn on the hot and cold faucet, and drain a little water. (Note: The heating switch can only be turned on when water flows out of the hot water port to prevent dry boiling).

In fact, the water purifier and the water purifier are the same thing, there is no difference, you should be talking about a water dispenser, then this must be a water purifier is better, saving money and convenient. The main thing is to hurry up hygiene.

There are five types of household water purifiers, which are specifically divided into:

Pre-filter: Solve the rust, sediment, suspended solids, etc. caused by the secondary pollution of the tap water pipe network and water tank, and protect the household water equipment from unnecessary damage or maintenance caused by impurities.

Water purifier: From the level of deep purification of the water in the whole house, the water becomes green and blue, and the water is removed from the discoloration, odor, organic residue, bleaching powder residual chlorine, heavy metals (such as lead, mercury, chromium, arsenic), etc., and impurities are removed. The purified water is very healthy for bathing, washing face, brushing teeth, washing rice, and washing vegetables.

**Water softener: Solve the problem of scale in domestic water, prolong the life of wading equipment and reduce the failure rate, and take a bath in household water is the same as doing a spa.

Water purifier: a kind of water purification equipment, through the reverse osmosis method, the raw water is filtered (physical treatment method) and then produced without adding any compounds. It can remove discoloration, odor, residual chlorine, heavy metals, bacteria, viruses, etc. in the water, and it can be drunk directly.

Ultrafiltration: retains beneficial minerals and removes residual chlorine, discoloration and odor, bacteria and viruses, heavy metals, etc.

The choice of water purifier can be based on:

1. According to the local water quality, we can observe whether there will be scale in the tap water at home, and whether there is any discoloration and odor. You can also search for local raw water sources, industry, mining, or call ** to the local health department to ask how the local water quality is. Then ask the property in the community whether it belongs to the secondary water supply and water pipes, etc., so as to judge the general situation of water quality.

2. According to the water demand of the household, the drinking water in the household can be divided into the daily life water that is not imported and the drinking water that is inlet according to the use. For domestic water, you can choose whole-house water purification, such as **clean water and **soft water.

If you want to drink water directly, you can choose a water purifier or an ultrafiltration machine, and then use it with a pipeline machine.

3. It is best to purchase household water purifiers according to the installation location and space before decoration, and you can measure the position and size of the water purifier at home in advance. If it has been renovated, you can consult a professional water purifier personnel to provide the location and method of water purifier installation, reference opinions, etc.

1. Understand the local water quality first: the water quality in the north of China is hard and has many impurities, the water quality in the south is soft, and the heavy metals and secondary pollution are serious.

2. Check whether it is convenient to replace the draft liquid of the water purifier filter element: whether it is a standard model, because the standard model filter element is easier to buy.

3. Choose a cost-effective water purifier: the quality of the water purifier should be good, the performance should be stable, and there should be strong professional technology and good after-sales service.

Note. 1. Look at word of mouth, quality, brand, and after-sales.

2. The water purifier is divided into two series, and the ultrafiltration water purifier has a simple structure, which can filter impurities, rust, bacteria and other impurities and harmful substances in the water; Reverse osmosis water purifier is suitable for family use, its water purification effect is ideal, it can effectively remove bacteria, heavy metals, organic matter, different colors and odors in the water, etc., and can be drunk directly.

3. The difference between ultrafiltration and reverse osmosis: the purification effect is different, the precision of ultrafiltration purification membrane is, and the accuracy of reverse osmosis membrane is.

4. Tips: Before using it for the first time, the water purifier should be rinsed to flush off the protective liquid in the water purifier, and rinse for 15 minutes until the produced water is clear and foam-free. Turn off the sewage faucet, bury the purification faucet, and use it normally after five minutes of water production.

The selection method of household water purifier is as follows:

1. Select according to local water quality. The principle of the water purifier is to filter harmful substances to the human body and purify the water quality through the terminal water treatment. Depending on the water quality in different places, the functional design of the water purifier is also different.

Generally speaking, the water quality in the north is hard and there are many impurities, so you should choose a water purifier or water softener with ion exchange resin filter element; The water quality in the south is soft, heavy metals and secondary pollution are serious, and families with high water quality requirements can choose a pure water machine, and if the local water quality is better, you can choose an ultrafiltration machine.

2. The filter element must be suitable. The water purifier is mainly filtered through activated carbon, ceramics, etc., which is easy to breed bacteria and pollute the water source; The second-generation water purifier uses artificial polymer membrane filtration, which has a significant effect on removing harmful substances in the water, but it also filters out trace elements that are beneficial to the body; The third-generation water purifier adopts nanocrystalline filter technology, which solves the defects of the second-generation water purifier. Therefore, when choosing a water purifier, you must be clear about the filtration technology and filter material.

3. Understand the filtration level of the water purifier clearly. Many high-level products on the market are filtered through repeated filtration, and the filtration effect is the same, in fact, we need to remove the role of each filter element when we consumers water purifiers. Water purification products are developed according to different use needs, and the filtration levels of the products are different to meet the needs of consumers in all directions.

4. Understand the size and installation location. Under normal circumstances, it is better to purchase a water purifier before decoration, consumers should measure the location and size of the water purifier to be installed at home in advance, or reserve the installation space and installation before decoration*, so that they can have a bottom in their hearts in the purchase of the store and avoid the twists and turns of improper purchase. If it has been renovated, you can ask the installer to come to your home to help check the layout, and provide the installation location and * reference opinions of the water purifier.

Generally, there are door-to-door installation services.

5. Choose a regular brand. If it is an unfamiliar brand, you may wish to check the test report and qualification certificate of the water purifier to see whether the brand has a health license endorsed by the national department, whether it has passed the appraisal of the national technical supervision department, and meets the national "drinking water quality standards". This is a necessary condition to ensure the purchase of a regular water purifier.

Today, with the continuous improvement of people's quality of life, water purifiers have gradually entered thousands of households from the beginning of the unknown, becoming an important part of people's quality of life, escorting people's life health and safety.

However, in order to help you alleviate the difficulty of choosing, the top five of the top ten brands are specially recommended to help you narrow the range of choices.
