2.The water purifier can well prevent the harm of secondary pollution caused by barreled water, which is more economical and cost-effective. 
3.The water purifier is opened immediately for drinking, which is basically safer and more convenient than boiling water.
4.The water purifier is a pollution-free and clean-free equipment, safe and reliable, and does not occupy a lot of space.
5.The cost of water purifier is lower than that of bottled water, and bottled water is pure water, lacking trace elements and mineral elements.If you eat it often, the water purifier is more effective. Precautions for installing the water purifier
1.Fill the glass with water, observe it in the light, and investigate whether there are other substances in the water, which can be a good way to observe your own water quality problems.
2. After receiving water, you can smell the smell. Do you have chlorine and other smells? Some words are not suitable for drinking directly.
3.Use tap water to make tea and wash clothes. If the tea changes and the clothes become hard in the sun, it means that the content of rust and miscellaneous matters in tap water is high.
4.Drink your own tap water directly. If you find that it is astringent, it means that there are many precipitates in the water, and you need to drink it after the water purifier.
5.If conditions permit, let more professional personnel check the condition of tap water. In addition, you can also purchase your own inspection tools to check and scientifically understand your own water quality problems.
6.You can properly ask about the overall water quality of your city from the news or environmental protection department before considering whether to install a water purifier.The above is an analysis of the advantages of the water purifier, which makes it clear that the water purifier is a relatively safe and cost-effective equipment.Research shows that the filter core of the water purifier can well block a large number of organic substances, impurities and some heavy metal ions, and can well prevent the body from ingesting toxic substances,and better ensure human health.
Use method of water purifier
1.If any abnormality or ambiguity is found during the use of the product, please call the regional sales service center or customer service in time.
2.Keep the ultrafiltration membrane filter element in a wet state after use.If the ultrafiltration membrane filter element is dried, the water yield will drop sharply and cannot be recovered.
3.Frequent washing of the water purifier can effectively prolong the service life of the water purifier.
4.With the long-term use of the water purifier, its water yield will gradually decline, but the water quality is still qualified and can be used safely.
5.When the water purifier fails, please immediately close the tap water inlet valve, cut off the water inlet of the water purifier, and do not disassemble it by yourself.
6.If the water purifier is not used for more than three days, the water purifier shall be repeatedly flushed for 2-5 minutes until the water in the water purifier is drained.
7.When the water supply is stopped, please turn on the sewage tap to drain the sediment and rust in the water supply pipe, and then turn on the purification tap to use the purified water.
8.The total water yield of the water purifier is related to the water quality of the water purifier.If the water quality of the water purifier is good, the total water yield will increase, and if the water quality of the water purifier is poor, the total water yield will decrease, and the service life of the corresponding filter element will be slightly shorter.
9.It is better to replace the filter element by the local maintenance service center or under the guidance of the professional service personnel of the local service center.I must pay attention to these nine aspects when using the water purifier. The service life of the water purifier will be significantly improved, which can save me a lot of money.
Water purifier purchase guide
1.Whether there is a product hygiene license approval.
Users must recognize the importance of product quality when purchasing water purifiers.Provisions on the sanitary supervision and administration of drinking water;It has obtained the hygiene license from the superior health supervision department, and has been identified by the technical supervision department to meet the national Standard for Drinking Water Quality.
2.Choosing the right filter element is crucial.
The first generation of water purifier is mainly filtered by activated carbon and ceramics,which is easy to breed bacteria and pollute the water source,and can not achieve the effect of clean water source;The second generation water purifier uses a variety of artificial polymer membrane filtration, which has a significant effect on the removal of harmful substances in water, but its fatal defect is that it filters out trace elements beneficial to the body.The third generation of water purifier uses nano-crystal filter technology, which well solves the defects of the second generation of water purifier and filters out harmful substances and heavy metals in water.So when you choose a water purifier,you must ask about the filter technology and filter material used to see if it meets your use needs.
3.Whether there is safe and effective sterilization technology.
There are two ways to sterilize the water purification equipment.One is to add disinfectant, which can kill some bacteria, but the disinfectant contains a small amount of chemical ingredients harmful to human health;The second is ultraviolet sterilization, which is one of the most effective sterilization technologies internationally recognized.Because ultraviolet sterilization is safe and efficient, it can quickly kill almost all bacteria; In addition,ultraviolet sterilization uses physical principles to sterilize without any chemical agent and will not have side effects on human body.
4.Whether there is a perfect after-sales service system.
Many consumers can't find the repair service telephone number or the address of the repair service company after purchasing some brands.This situation makes consumers very helpless and also causes a waste of resources.Many water purifiers become furnishings; After-sales of water purifier mainly focuses on the replacement of filter element.If the filter element is not replaced for a long time, it will pollute the water source, and the water purifier will also become a "sewage filter".When selecting the water purifier, we must choose perfect after-sales service, such as using the customer service system to track customer information and prompt customers and the company to replace the filter element.
5.Choose those with high performance-price ratio.
1.Different water purifiers have different water purification effects.Generally speaking, the primary filtration water purifier has a simple structure and is mainly made of activated carbon.Its filtration capacity is limited, and it can only be used for coarse filtration.The filtered water is best heated and boiled for drinking.Most of the water purifiers for primary filtration belong to low-grade water purification products, and the price of each set is between 10 yuan and 150 yuan.
2.Multi-stage filtration water purifier.This water purifier has two stages of coarse filtration and one group of fine filtration,and the fine filtration mostly adopts hollow fiber filter element, so the filtered water can be directly drunk.The multi-stage filter water purifier is a middle-grade water purification product, with the price of each set between 300 yuan and 500 yuan, which can be accepted by the working class and used by families more.
3.UF ultrafiltration nanofiltration membrane water purifier,composed of multistage prefiltration and ultrafiltration membrane, can intercept most of the bacteria and harmful substances.It is the most commonly used direct drinking water purification device with the most common separation and filtration effect in the market,while retaining the mineral trace elements beneficial to human body, and then using the advantages of KDF and activated carbon to effectively inhibit the growth of bacteria and fungi in the water and remove the color and odor, Ensure that the filtered water can be used more safely and healthily.Moreover, the water yield is relatively large, and the wastewater discharge is small, so it is faster and more convenient to use in the home kitchen without waiting for a long time. As a popular consumer product, the price of each set varies from 200 yuan to 5000 yuan according to different requirements.
4.RO reverse osmosis water purifier is the most ideal water purification product for the treatment of rural water and groundwater.It has three stages of pre-filtration,one stage of reverse osmosis membrane precision filtration and one stage of post-filtration.The filtered water is free of bacteria, viruses, heavy metals, pesticides, organic matter, minerals and peculiar smell.It is pure water and can be drunk without heating.This type of reverse osmosis water purifier is a high-end water purification product, and the price of each unit is between 1000 yuan and 5000 yuan.
6.Purchase according to water quality.
1.The hardness of water quality in different regions is different.The high hardness water quality in northern China and the limestone area in southern China have high content of calcium and magnesium ions in the water, which are easy to scale.Therefore, it is necessary to purchase an advanced filter water purifier with an ion exchange resin filter element.
2.For urban tap water with high chlorine content, strong color and odor, and high organic content, household water purifiers with high activated carbon load can be purchased.Because activated carbon has strong adsorption effect on residual chlorine and odor in water,and has obvious removal effect on organic matters.
3.For the purification of urban and rural water with turbid water quality,household water purifiers with dual functions of coarse filtration and fine filtration should be selected. If the water pollution is serious and it is required to completely remove any impurities in the water and drink directly without heating, the reverse osmosis water purifier should be purchased.
7.Some basic principles for selecting water purifiers:
1.The water purification products have high performance-price ratio: good quality and stable performance; Easy to use; Low maintenance and operation costs; Strong professional technology and good after-sales service.
2.Soft water products are selected for domestic water, and water with certain hardness (140mg/L - 200mg/L) is selected for drinking water.
3.The composite ultrafiltration machine is the best choice for areas with water hardness below 170mg/L.
4.In areas where the hardness of water is between 170mg/L and 250mg/L,it is better to use soft water for shower and laundry, and composite ultrafiltration water for direct drinking.
5.For showers in areas where the hardness of water is more than 250mg/L, it is better to use soft water for washing water, and select part of softened water (mixed with demineralized water and unsoftened water in a certain proportion) for direct drinking water, which is filtered by a composite ultrafiltration machine.
6.For water in areas with high fluorine, salt and sulfur, pure water machine shall be selected as direct drinking water and supplemented with trace elements.
7.For areas with heavy groundwater or sand and rust, it is recommended to install a precision filter after the master meter.
