Founded in 1936, Conligan is an American brand with a history of more than 70 years of water purification and enjoys a high reputation and brand recognition in the North American market. Many of Corrigand's products, including water-related components and raw materials, have passed NSF 42, 53, 58 and 401 certifications, and have obvious advantages in the fields of central water purification, central soft water, and commercial water purification, and the products have been recognized by major institutions. The world's tallest building, the Burj Khalifa in Dubai, uses Conligan's water purification solution, and Conligan's customers also include the Grand Lisboa Hotel in Macau and the Shanghai Pharmaceutical Research and Development Laboratory.
 
However, Kangligan did not pay enough attention to the household end water purification market, the number of products is very scarce, RO reverse osmosis water purifier is only US-3 this model on sale, its filter element filtration scheme is also quite simple, activated carbon RO membrane The combination of activated carbon is a little powerless in dealing with the complex water pollution environment in various parts of China, activated carbon and RO membrane lack of filter layer, and the loss of carbon powder can easily lead to RO membrane blockage. US-3's water purification performance is quite average, the water purification flow rate is only 50G, the user needs to wait for about 1 minute to receive a full glass of water, and the water storage bucket has become an indispensable auxiliary accessory, but the water storage bucket has the risk of secondary pollution of purified water, less than 1000L of rated total water purification, which means that the frequency of filter element replacement is high. The US-3 is priced at nearly 5,000 yuan, and there are more high-end flagships from other brands to choose from at this price point.
 
Although the water purification performance is not ideal, Corrigan still inherits the unique rigor of the American brand. Kangligan's water purifier is made of antibacterial material injection molding; The unique hidden design of the pipeline, the interfaces of all filter elements are integrally formed, and there is no water pipe connection inside, which effectively reduces the hidden danger of water leakage; In terms of material selection, Kangligen has built-in Japanese Kuraray coconut shell sintered activated carbon, which can greatly increase the density and number of micropores of activated carbon with the sintering process, thereby improving the adsorption capacity of activated carbon and ensuring that the effluent quality is refreshing and delicious.
