RO reverse osmosis water purifier recommended series/model: WTE-PT63-4015, WTE-PT63-4012  
 
"Mastering the core technology" is Gree's proud Slogan in air conditioning products, although it is positioned as a comprehensive home appliance company, but Gree's current revenue source is mainly its air conditioning business, the road to diversification is still long, the market recognition of Gree's horizontal extension of household appliances needs to be improved, and the water purifier is only a subtle branch of Gree's multi-product strategy line, but as one of the largest home appliance companies in China, Gree still has something remarkable in terms of brand reputation, product quality and after-sales service.
 
The design of Gree water purifier is relatively mediocre, rarely see the unique appearance of the shape, the traditional style is still the mainstream form of Gree products, the biggest feature is that the first filter layer abandons the commonly used PP cotton, but directly uses the external pressure PVDF ultrafiltration membrane, PVDF Chinese name is polysylidene fluoride, the disadvantage of this material is that the filtration accuracy is lower than the general ultrafiltration membrane, but the acid and alkali resistance is strong, can resist high concentration of residual chlorine oxidation, and can be repeatedly cleaned and utilized. Gree claims that through this improvement, it can effectively protect the post-filter membrane, so that the overall filter element life is increased to 3 years, and the user needs daily cleaning and maintenance is only the first ultrafiltration membrane, although this scheme can indeed reduce the cost of water purification in the later stage, but it has also made a certain compromise in terms of flux, and the water purification flow rate is only 100G, so the water purifiers that use this filtration scheme are equipped with water storage buckets.
 
In order to dispel the user's concerns about the secondary pollution of the water storage barrel, Gree also set up a filter layer after the water storage barrel, which uses the composite filter element of ultrafiltration membrane activated carbon, which can effectively filter germs and improve the taste, although the risk of secondary pollution of the water storage barrel is small, but over time, the sealing of the water storage barrel will be reduced, so this design is still very necessary for products with buckets, but frankly speaking, the water storage barrel is still just a fig leaf for low-throughput products. And the mainstream model WTE-PC16-5X608A is priced at nearly 4000 yuan, and the cost performance is average.
 
In addition, Gree has also launched large-throughput products that cater to the mainstream of the market, WTE-PT63-4012 is Gree's representative work, its purification performance is good, the purification flow rate reaches 400G, the pure wastewater ratio is 2:1, both the water purification rate and the water purification efficiency are at the first-class level, but the filter element scheme of this product also has similar defects as the Xiaomi water purifier, that is, there is no obstruction between the activated carbon filter element and the RO membrane, and the falling toner is easy to flow directly into the RO membrane to cause blockage. The measured value of its rated total water purification is only 2000L, which is not satisfactory considering the selling price of more than 4000 yuan. However, WTE-PT63-4012 is one of the few models with a new design, and its simple and beautiful shape has also captured many consumers.
 
On the whole, Gree's high-end water purifiers are at a decent level on the market, and the high pricing has weakened the attractiveness of Gree's products to a certain extent; The performance of low-end products is quite average, priced at more than 2000 yuan, and there are more and better products to choose from at this most competitive price. However, as a veteran home appliance manufacturer, Gree's advantage lies in the service outlets all over the country.
