Coway’s first R&D centre was established in 1993 and a year later, production of our very own products was carried out. The research and development is primarily focused on delivering customer satisfaction and consumer convenience rather than increasing profits for the company itself.

Equipped with 182 cutting-edge devices and equipment, our R&D centre was designated by TÜV SÜD, one of the world’s leading technical service organisations, to run self-analysis and test RoHS (Restriction of Hazardous Substances) electrical and electronic products.

Adding another feather to the cap, our R&D centre was later certified by WQA (Water Quality Association, USA) as a Recognized Testing Laboratory focused on running efficiency and safety tests.

Given the trust from these established organisations, we strive to instil our knowledge and expertise into the products and services especially for our customers all over the world.


Strengthening competitiveness of existing businesses and laying the foundation for future growth.


Yugu Factory

After a year of completion, the Yugu factory in Korea expanded and became the world’s largest consumer electronics manufacturing site in 1995. Soon after, the factory started manufacturing filters in 1997 with its high-tech Programmable Logic Controller-based automated facility that produces 1.44million water filtration devices annually.

“Coway is the largest indoor filter manufacturer not only in Korea, but the world.”

With a building area of 1,2859.98sqm and a floor area of 20,450.79sqm, the factory is equipped with nine water filtration device lines, four air purifier lines, nine filter lines and a carbon block line with an annual production of over 20million filters, water filtration devices and air purifiers. (as of April 2016)

The factory then focused on the environment and consistency with the aim of achieving zero waste, defects and breakdowns with the introduction of a system that achieves zero-fault during production, an Environmental R&D Centre and Water Analysis & Research Centre (WARC). These introductions have significantly improved productivity and quality and at the same time, reduced costs.

“Every single product goes through vigorous testing over 1,000,000 times.”
