RO reverse osmosis water purifier recommended series/model: A large flow series, V6 series, K7 series
 
Founded in 1992 in Shenzhen, Guangdong, Angel entered the water purification industry earlier than Qinyuan, and has established a comprehensive water purification product line, covering the entire household, commercial and other water purification fields. Angel has good technical strength, participated in the drafting of a number of industry standards for water purifiers, and is also one of the drafting units of the mandatory national standard of "Water Efficiency Limit and Water Efficiency Grade of Reverse Osmosis Water Purifier". At present, Angel's market share ranks in the second echelon, and it has a high brand awareness in the offline market.
 
Since the technical threshold of the water purifier is not too high, in order to strengthen the difference of products, many companies are keen on "stacking", although the "stacking" products are not necessarily sophisticated, but the good materials are definitely the performance basis of the ultimate product. As early as 2014, Angel signed a strategic cooperation agreement with Dow of the United States, and its high-end A large flow series of models are equipped with the best Dow RO membrane recognized in the industry, with a water purification flow rate of up to 500G and a rated water purification of up to 7000L. However, the price of A large flow series is more than 5000 yuan, and the cost performance is average.
 
As for the V6 and K7 series, they are equipped with ordinary RO films, although the water purification performance has decreased compared with the high-end A series, but the price is almost halved, which is a cost-effective choice launched by Angel to seize market share. The K7 is more simple in appearance and shape, and the texture is quite delicate; Although the V6 is a traditional shape, it has the function of ultrafiltration water, RO and purified water, which is better than the K7 in terms of practicality in application scenarios. It should be reminded that Angel also has a lot of low-throughput models below 100G, and the price is also high, so it is not recommended to buy.
 
The "folded" filter element is the unique feature of Angel water purifier, whether it is A large flow series, or V6 and K7. The traditional PP cotton filter element mainly uses the direct roll process, although the filtration effect is outstanding, but it will have a certain impact on the flow rate, Angel will cut the PP cotton raw material into long strips, and then fold and reduce the cylindrical shape, the PP cotton filtration area is increased by nearly 9 times, which can effectively intercept insect eggs, rust, colloids and other pollutants, and reduce the impact on the water flow rate. In addition to PP cotton, Angel also introduced this process into the US PRO composite filter element, which is surrounded by a pleated ultrafiltration membrane and wrapped with a sintered high-density activated carbon rod inside, which can efficiently remove most impurities and adsorb residual chlorine and odor molecules, reducing the filtration pressure of the RO membrane.
 
Unfortunately, Angel has not improved much in terms of appearance and styling overall, and the traditional design of the exposed filter element is still the mainstream form of Angel's product water purifier, and the rough industrial style of ten years ago continues to this day, and there are few eye-catching design features. In addition, Angel has not launched a smart water purifier so far, and there is still some room for catching up with the trend of the times in the upgrading of the product, but fortunately, Angel's humanized functions are relatively in place, such as the built-in OWP work delay protection technology similar to that of Janet, and the water will be automatically cut off after one hour of continuous work; On the basis of the filter element life replacement reminder light, a buzzer is added, which allows users to detect the condition of the filter element in time, and consumers can also purchase a faucet with TDS detection light, which can be detected at the first time when the water quality changes, which is more intuitive and convenient.
