Household water purifier water dispenser selection guide: understand the filtration technology focus on water quality needs focus on brand after-sales

Water purifier needs in different scenarios
                    
                
 Drinking scenarios: For families with drinking needs, such as tea, milk powder, etc., you need to consider a water purifier that can provide water with the right temperature and high purity. The all-in-one water purifier and dispenser is a good choice, which combines the functions of water purifier and water dispenser, and can be filtered directly on a machine to choose the desired temperature and water volume, which is convenient, without the need to bury the line, and there is no problem of residual water in the water pipe. However, its water purification flux is generally smaller than that of a kitchen water purifier, and it may be slower to receive a large amount of water. If your home is large and populous, you can also choose the combination of “kitchen water purifier + pipeline machine”, the kitchen water purifier is responsible for filtration, pipeline machine for heating and controlling the amount of water, temperature, but you need to bury the line in advance before the renovation.

Kitchen water scenario: Kitchen water consumption is large, and the speed of water discharge is required to be high. Therefore, when choosing a water purifier, pay attention to its flux, the larger the flux, the faster the water speed. Reverse osmosis water purifier and ultrafiltration water purifier are common choices. Reverse osmosis water purifier has high filtration precision and can remove various harmful substances in the water, but the water output is relatively small; ultrafiltration water purifier has a large water output, which can meet the demand for large amounts of water in the kitchen, but it can't completely filter heavy metal ions. If the local water quality is good, ultrafiltration water purifier can basically meet the demand; if the water quality is poor, especially heavy metals, bacteria and other pollutants in the water is more, reverse osmosis water purifier is more appropriate.

Whole house water scene: If you want to meet the whole house “drinking, food, washing, bathing, ice” and other diversified water needs, you can consider choosing a water purifier with a variety of functions, such as instantaneous water purifier, which integrates a hot water machine, pipeline machine, cold drink machine, ice machine and other functions, can save a lot of bottles and cans and kettles, etc. However, the price of this type of water purifier is relatively high, but it is not very expensive. However, this type of water purifier price is relatively high, need to choose according to the family budget and actual needs. In addition, you can also choose the “kitchen water purifier + drinking machine” program, the kitchen water purifier to meet the kitchen large amount of water and the whole house of the basic water purification needs, drinking machine to meet the drinking of the temperature and the amount of water to the precise control.

Factors to consider when choosing a water purifier
                    
                
Filtration: common filtration methods include RO reverse osmosis filtration, ultrafiltration filtration, etc. RO reverse osmosis technology has the highest filtration precision, and can remove bacteria, viruses, heavy metals, organics and other impurities in the water, and the filtered pure water can be directly consumed; ultrafiltration filtration can remove sediment, suspended solids, rust, bacteria, colloid, and some large molecules of organic matter in the water, etc., but it can not completely filter heavy metals, ions, and so on. Ions. If the local water quality is poor, it is recommended to choose RO reverse osmosis water purifier; if the water quality is good, ultrafiltration water purifier can also meet the basic needs.

Filtration level: choose at least 5 levels of filtration membrane water purifier, 6 level is even better. Generally the first two layers are PP cotton + front activated carbon cartridge, used to filter dust impurities; the middle is RO membrane, filtration accuracy can reach 0.0001 micron; the back two layers are activated carbon, can make the water become soft and sweet, improve the taste.

Heating system: common heating system has rare earth thick film, stainless steel heating, quartz tube heating and so on. Rare earth thick film heating has the advantages of high efficiency, fast heating, anti-dry burning, long service life; stainless steel heating is relatively common, but there may be uneven heating; quartz tube heating may be fragile. If the heating function has high requirements, it is recommended to choose rare earth thick film heating water purifier.

Water quality: it is recommended to choose pH value is weakly alkaline or with mineralization of weak alkali, strontium-rich filtration technology such as water purifier, so that the water tastes better, but also more in line with human health needs.

Filter material: the main factor affecting the water purification effect of the water purifier is the filter. The market water purifier mainly uses PP cotton filter, activated carbon filter, ultrafiltration membrane filter, RO filter, etc. PP cotton filter is mainly used for coarse filter, blocking rust, sand and other large particles of impurities; activated carbon filter used to adsorb odor in the water, chlorine and some organics, to improve the taste of water; ultrafiltration membrane filter can remove bacteria, colloid and macromolecular organics; RO filter is the core of the reverse osmosis water purifier, which can filter out almost all the impurities. RO filter is the core of reverse osmosis water purifier, which can filter out almost all impurities. Different materials have different replacement cycles and need to be replaced regularly according to the actual situation.

Water purification: the service life of a water purifier is mainly determined by its rated water purification, once the water purification reaches the amount of water, the water purifier's water purification capacity will be greatly reduced, this time you need to replace the filter cartridge in a timely manner. Therefore, when choosing a water purifier, pay attention to its rated water purification, choose a larger water purification products, you can reduce the frequency of filter replacement.

Membrane specifications: also known as the flux of the water purifier, mainly affects the water purifier's water discharge rate, generally expressed in gallons (G), 1G = 3.785L. common flux specifications on the market are 400G, 600G, 800G, 1000G and so on. If you have a large family or use a lot of water, it is recommended that you choose a water purifier with a larger capacity to ensure that you can meet your daily water needs.

Additional features: In addition to the basic water purification function, nowadays water purifiers have added many additional features, such as TDS detection function to monitor the water quality in real time; zero stale water function can avoid the phenomenon of stale water in the water purifier when it is not used for a long time; UV lamp sterilization function can further kill bacteria and viruses in the water to protect the safety of drinking water. These additional functions can be selected according to individual needs.

The importance of brand and after-sales service
                    
                
 Brand: Choose a well-known brand of water purifier, its product quality and after-sales service is more guaranteed. Big brands usually invest more in research and development, production, quality control, etc., and the performance and stability of their products are better. For example, Qinyuan, Xiaomi, Ekite, Angel, Midea, etc. are more well-known brands in the market, and their products have a good performance in filtration effect, durability and other aspects.

Certification: water purifiers need to pass some certifications, such as 3C certification, mainly to protect the electrical safety performance of the product; health license approval, used to protect the health performance. Any product that does not have these two certifications has certain hidden dangers, when choosing to pay attention to check whether the product has the relevant certification.

After-sales service: good after-sales service can make users feel more at ease in the process of use. When choosing a water purifier, it is important to understand the brand's after-sales service, including whether to provide door-to-door installation, cartridge replacement reminder, fault repair and other services, as well as the response speed and quality of after-sales service.
