Recommended series/model of ultrafiltration water purifier: HU603-3A, HU203-3, HU603-5(A)
 
In 1985, Zhang Ruimin, then director of Haier, took the lead in smashing 76 "third-class" refrigerators, resulting in a giant brand of Chinese home appliances, so far, Haier's turnover has exceeded 200 billion yuan, and rich household appliances have already entered thousands of households. From 2010 to the present, Haier has carried out the layout of the whole product line in the water purifier market, and most of the water purification products on the market are involved, Haier is one of the drafting units of the national standard "reverse osmosis water purifier water efficiency limit value and water efficiency grade", and it is also one of the first brands to pass the A-level water efficiency certification.
 
Although it is a big coffee in domestic home appliances, compared with brands such as Midea and Qinyuan that have been deeply cultivated in the water purification market for many years, Haier's start is indeed late, and its products are relatively popular. In terms of household end water purification products, Haier also takes into account the R&D and sales of RO reverse osmosis water purifiers and ultrafiltration machines, the comprehensive performance of the products is good, and the cost performance is relatively high, taking HRO4H22-4 (J) as an example, the price is only 2500 yuan, but it is equipped with a high-end Dow RO membrane in the United States, and the water purification flow rate reaches the current mainstream 400G, which is enough to meet the direct drinking water needs of a family of four. Unfortunately, the rated total water volume of most of Haier's products is small, generally only 2000-3000L, and the durability of the filter element needs to be improved compared with first-line brands.
 
"Big data" is playing an increasingly important role in product development and decision-making support, and through years of accumulation, Haier, like Qinyuan, has carried out big data collection on water quality across the country, and has now established a water quality database covering major population areas. Considering that the water quality varies greatly in various parts of China, the high-end model represented by the HRO6H22-4 can monitor the inlet water quality in real time through the built-in sensor, and adjust the output power of the booster pump with the circuit control system to achieve intelligent adjustment of the pure wastewater ratio from 1:1 to 2:1, so that the machine can achieve a better balance between the purification effect and wastewater discharge according to the different water quality environments in China.
 
In terms of appearance design, whether it is RO reverse osmosis water purifier or ultrafiltration machine, Haier's product modeling is still based on traditional modeling, and compared with the increasingly popular one-piece design, Haier simply replaced the stainless steel material on the basis of this public model, and strengthened the hard sense of external lines, the overall shape presents a strong American heavy metal style, and the product perception has been improved, but from the perspective of practicality, the non-integrated design is always easy to hide dirt and dirt, and it is relatively troublesome to clean up later. In addition, Haier has not launched smart water purification products so far, which is a small pity.
 
Overall, Haier's water purification products are still worth buying, and consumers who pursue cost-effectiveness can pay attention to models such as HRO4H22-4 (J) and HRO4h29-4, which can be purchased at a price of less than 3,000 yuan. Consumers who pursue high-end can pay attention to models such as HRO6H22-4, which are Haier's highest level in terms of design and water purification effect; If you live in areas with soft water quality such as South China, ultrafiltration models such as Haier's HU603-3A are also worth buying, but it should be noted that ultrafiltration water is not recommended to drink directly. The installation service after-sales system that is widely distributed throughout the country is also the advantage of Haier to gain many fans.
