Coway, the "Best Life Solution Company," is committed to advancing its corporate social responsibility (CSR) by consistently championing both environmental preservation and social equity. Rather than viewing its corporate citizenship through any singular lens, Coway aims to address a diverse range of societal needs through distinct, dedicated initiatives. This June, Coway helped enable positive transformation across communities in the company’s native South Korea via a dual approach: protective environmental stewardship and proactive social inclusion. From revitalizing local waterways to championing indoor health equity and promoting inclusion for disabled individuals, Coway’s ongoing CSR campaigns exemplify its dedication to building a healthier, more harmonious future. Restoring Ecosystems Hand-in-Hand with Local Communities   Participants of Coway’s 2026 River Plogging Campaign Environmental sustainability at Coway is not just some passive corporate mandate, but instead is an active, shared endeavor that engages employees, local communities and future generations in an effort to bring about real change. One such example of this philosophy is the Coway River Plogging Campaign, which marks its fifth consecutive year of activity in 2026. This campaign, in which both company employees and consumers alike are able to participate, blends health-conscious walking and jogging with hands-on environmental cleanup along local rivers and coastal areas. By combining jogging or walking along waterways with trash collection, the program aims to preserve the health of our rivers and oceans while fostering a culture of simple acts of environmental stewardship in everyday life. This year’s campaign drew 460 participants, propelling the campaign’s total number of contributors across the past five years to an impressive 6,800. For 2026, Coway also expanded the scope of the program’s involvement to local running crews, daycare centers and even newcomers to the Coway R&D Center in order to help clean up the areas surrounding its operating sites in Seoul, South Korea. Ensuring Health Equity for Vulnerable Households Coway understands that true social accountability means ensuring that all the fundamental pillars of health – including clean indoor air – are accessible to all. In line with this pledge, Coway officially renewed its commitment to the ‘Indoor Environmental Improvement for Vulnerable Groups’ agreement, as organized by the South Korean Ministry of Climate, Energy and Environment. This public-private joint agreement unites government forces with major domestic companies in order to create a collaborative framework aimed at installing environmental safety nets for the most vulnerable in society. This year, Coway was proud to stand alongside 16 other participating companies, marking its ninth consecutive year of unwavering participation since 2018.   Coway Receives Recognition for its Commitment to the ‘Indoor Environmental Improvement for Vulnerable Groups’ Agreement For the past nine years, Coway has been providing its state-of-the-art air purifiers alongside complimentary filter replacement and expert maintenance services to help realize the agreement’s goals. To date, Coway has supplied a total of 147 air purifiers to households in need across South Korea, a contribution that previously earned the company the prestigious Minister of Climate, Energy and Environment Citation. Furthermore, Coway has been extending this support to local youth facilities and schools, subsequently having donated over 500 air purifiers as of 2025. Fostering Social Harmony Through Music   The Coway Mulbit Choir Holds its Third Annual Regular Concert Alongside ecological stewardship, Coway’s CSR vision also embraces the core tenets of Diversity, Equity and Inclusion (DEI). This commitment was beautifully underscored on June 23, when the Coway Mulbit Choir, a professional choir of visually impaired vocalists, staged its third annual regular concert in Seoul. Held under the title ‘The June We Loved’, this free-of-charge performance drew a packed auditorium of over 650 attendees made up of local residents, Coway employees and their families. In a break from traditional choral practice, the second half of the concert transformed into a musical drama, with the immersive narrative even having some of the choir members themselves perform as actors onstage to deliver powerful messages of nostalgia, shared comfort and the unifying power of empathy to their captivated audience. Redefining the Corporate Journey Toward Sustainable Wellness By actively addressing environmental restoration, health equity and excellence in diversity through dedicated, parallel tracks, Coway is charting its own distinct path for CSR excellence. The wide range of activities, achievements and activations undertaken by Coway this June showcase how, when corporate capacity and commitment align with community needs, the resulting impact can truly help transform society.

Coway's Water Sommeliers Established in 2019, Coway’s Water Taste Evaluation & Research Lab, located in the company’s Environmental Technology Research Institute (R&D Center) in Seoul, Korea, is home to a unique group of experts: nationally-certified water sommeliers. Coway is the only company in the industry operating a dedicated water taste research lab. Harnessing Science for Better Tasting Water Similar to their namesakes in the wine industry, water sommeliers are specialists able to evaluate the sensory qualities of water, ensuring that Coway’s water purifiers deliver water that is as enjoyable to drink as it is safe. By studying the factors that influence water quality and taste, they validate and enhance the drinking experience. This year, Coway certified 15 new water sommeliers, bringing the company’s total to 44 – the largest in the industry. Among them, 10 hold Advanced Level certifications, enabling them to lead training and education in water taste.   Coway’s Environmental Technology Research Institute (R&D Center) in Seoul, Korea Since the launch of the initiative in 2012, Coway has been expanding its water sommelier program in order to strengthen its research capabilities. The lab also pioneered the industry’s first proprietary water taste standard, the ‘GPT (Good Pure Tasty) Water Index.’ Today, water sommeliers play a central role in product development, assessing water taste and quality throughout filter design and testing processes. Their expertise ensures Coway is delivering to its customers water that is not only clean and safe, but that is also consistently pleasant across the company’s diverse range of markets.   Coway's Icon Water Purifier 2 (CP-7211N) Achieving International Certification and Recognition Beyond this taste expertise, Coway has also achieved international recognition for the water safety and performance of its products. Coway was the first in the industry to obtain global certification from the Water Quality Association (WQA), a recognized international certification body for water purifiers, back in 2008. Additionally, Coway’s filters have been certified by the WQA to a variety of leading industry standards, including NSF/ANSI 42 (aesthetic effects), 53 (health-related effects) and 58 (reverse osmosis systems). More than 80 of the company’s products carry the WQA’s Gold Seal Mark, a clear assurance of product quality, durability and safety. Setting the Global Benchmark for Water Expertise Moreover, Coway’s specialized overseas research & development (R&D) systems empower the company to develop custom products tailored to the specific requirements of each country it operates in. By collecting and analyzing water samples the world over, Coway has developed its proprietary “Water Map”, a database containing findings from approximately 2,700 water sources in 41 countries. This extensive catalog of samples allows Coway to deliver optimal and localized products and services that align with each region’s unique water characteristics. With the industry’s largest team of certified water sommeliers, advanced R&D capabilities and internationally-certified products, Coway continues to set the benchmark for water expertise. Coway’s mission is simple yet powerful: to deliver water that is safer, cleaner and consistently better-tasting, every single day.
