We have developed a database on the world's water and air quality in the environmental analysis center. We have an infrastructure that can reliably provide clean water and air at any time and any place. We address all water quality situations that change depending on geographical conditions and environment by collecting and analyzing the water samples from about 40 countries and developing our own ‘Coway World Water Map'.
Air quality varies depending on space. In an effort for customers to enjoy clean indoor air no matter where they are, we visit various places where customers actually live to analyze air quality through ‘IAQ(Indoor Air Quality) Field Test'. As of December 2015, we developed an index on 16 different types of air quality by collecting more than 100 million air quality data from about 1,300 households. The air quality index allows us to quantify the impact of pollutants on health and provide filters best customized for each customer's needs.Our passion to study water and air led to the launch of innovative products and patents. Coway holds 3,530 intellectual property rights in total (as of December, 2015), including more than 1,800 patents related to water and air.
