As some of Coway's high-tech products can have a high initial cost to consumers when they first hit the market, Coway adopted a rental business model in 1998 to make them more accessible. As the cost to consumers decreased over time, people began widely adopting the products. Coway's attentive after-rental service also raised its corporate reputation with cody system, a trained purifier expert visited customers regularly, changing filters and ensuring that products are in optimal condition, free of charge. In 2006, the number of Cody System experts had risen to 11,000 with customers nationwide numbering over four million.

In 2003, Coway enlarged its business to go global with its first overseas business starting in Japan. Coway then expanded to Thailand, China, and Malaysia. By May 2007, Coway opened its first U.S. subsidiary in Los Angeles, signaling its commitment to the U.S. market. The company has also set up a number of logistics bases and planned to establish subsidiaries in Europe.
