Founded in the United States in 1925, Eco has been focusing on the field of water purification for nearly 100 years, and has now become a subsidiary of Warren Buffett's company, and the world's first water softener was born in the hands of Lindsay, the founder of Eco. Eco is the first ISO certified water treatment product manufacturer, has a deep accumulation in research and development technology, more than 95% of the components for its own research and development, manufacturing, currently has 38 water purification equipment production lines in the world, its ERO-375 and HERO-375 series reverse osmosis water purifiers through NSF, WQA and other authoritative certification, ERO-375 series in the United States "Consumer Reports" also won a high score of 91 points. In the Chinese market, Eco has close strategic cooperation with famous real estate companies such as Vanke, Sunac and Poly, and provides integrated water purification solutions for many high-end residences.
 
At present, Eco has more than 10 types of household terminal water purifiers on sale, including RO reverse osmosis water purifiers and ultrafiltration products, but Eco's main focus is on systematic water purification projects such as residential buildings and commercial buildings, as well as the field of whole-house integrated water purification. Although the factory directly under Jiangsu has been in operation for many years, the localization of its water purifiers still needs to be improved, especially in the filtration program.
 
The water quality situation in various parts of China is quite different, and the secondary pollution of tap water pipelines is relatively serious, and the water purifier has high requirements for intercepting large particle pollutants such as rust and colloids. Therefore, even if Eco's products have received good evaluations in foreign evaluation institutions, but the problem of "water and soil adaptation" has to attract the attention of consumers, Eco also mentioned on its product introduction page that considering the normal service life of the water purifier, it is not recommended that some areas with poor water quality buy its water purifier, even if they live in areas with better water quality, consumers should also install a pre-PP cotton filter device to ensure the long-term normal operation of the water purifier.
 
Although the filtration solution does need to be optimized, as a long-established manufacturer of water purification equipment, Eco has naturally accumulated a lot of housekeeping skills. The water pressure problem of high-rise residential buildings has been plaguing water purification equipment manufacturers, for water purifiers, too much or too small water pressure will affect the normal operation of the internal filter element, and even cause harm to its service life, Eco's ERO311-4-UC has a unique built-in intelligent pressure sensor, which can automatically adjust the output pressure of the booster pump through circuit control to achieve the effect of "pressure stabilization", with parallel double RO membrane design, The water purification flow rate of ERO311-4-UC reaches the top 800G in the industry, and it only takes 6 seconds to fill a cup of 200ml of direct drinking water.
 
ERO311-4-UC as Eco's flagship product, in the shape of the natural is also quite painstaking, in fact, as consumers pay more and more attention to the visual pleasure brought by "appearance", the appearance design has been in recent years many water purification manufacturers to try to explore the direction. Different from the minimalist design that the new brand is keen on, the design language of ERO311-4-UC takes "elegance" as the theme, the shell with black as the main color appears calm and atmospheric, the rose metal lines on the edge outline the exquisite beauty, and the display screen dotted in the lower left corner is not only practical, but also enhances the overall sense of science and technology, but the price of up to 10,000 yuan has also reduced the market competitiveness of this product to a certain extent.
 
If you want to buy cost-effective models, consumers can pay attention to ERO001-3, ERO002-3 and other models, whose water purification flow rate is 100G, and the water production rate is 50%, which is a relatively acceptable choice, and the price is between 2000-3000 yuan; The 800 series, which has a higher sales volume, is actually not worth recommending, although its powerless design is more attractive to users who are unwilling to modify indoor circuits, but its water purification flow rate is only 50G, and the pure wastewater ratio is 1:3, which means that three cups of wastewater need to be discharged to produce a cup of pure water, which is really difficult to achieve. Flagship products such as the ERO311-4-UC have excellent performance and deserve the attention of consumers with sufficient budgets.
