Jung Hwan Lee sharing different Coway products

R&D genius spotlight: Jung Hwan Lee

Coway’s Research and Development Team is on the cutting edge of major health technologies, constantly researching to bring happier, healthier lives to millions around the world. With over 366 researchers, developing technologies around all aspects of life, it is one of the most robust teams of experts in development of clean air and water—and much more. Whether it’s billions of data points to document air quality or 23 certified water sommeliers—when we say we’re obsessed with health, we mean it.

One of our leaders with a #HealthyObsession is Principal Research Engineer Jung Hwan Lee. Working with the WaterCare Development team, Lee helped perfect the design of Aquamega, with the help of some inspiration from his kids.


“I was contemplating how to make a good habit of drinking water for children, and I developed a smartphone application to link with a water purifier. I'm a father who loves the company for providing excellent products.”

–Jung Hwan Lee, Principal Research Engineer

One of the main focuses of the Development Team is to bring efficiencies to every system within a Coway product. Lee was looking for ways to maintain the cooling functions inside Aquamega. There were some difficulties at first, finding a solution to minimize energy consumption.  One day, Lee was running errands, and the goods at a local store inspired him.

“I randomly went into a store and got an idea—I realized that creating insulation around the parts can help with energy. I learned a valuable lesson that anything can be done if you have a goal, and the passion to complete it.”

One additional challenge faced by Lee was the vastly different contaminants found in each region of the world. #Aquamega had to be versatile enough to capture all sizes and shapes of harmful contaminants in order to be effective around the world. That’s why Lee and his team regularly visit a variety of foreign places, testing and researching the best capture techniques.

“To ensure we have products that will be loved by customers, we prioritize quality and innovation. We also create products for which the customer can easily install, maintain, and manage the product.”

Usability is a huge factor to the innovation and success of Coway. They are products that work well for each user and fit beautifully into their home. In large part, it’s thanks to engineers like Lee and his team of researchers. Staying on the cutting edge means thinking on the cutting edge.


1Coway air purifiers have been proven to trap dust, pollen, dander, viruses and bacteria in the air based on KCL (Korea Conformity Laboratories) testing.They have been tested in a 30㎥ size chamber according to the Korea Air Cleaning Association standard (SPS-KACA 002-132:2022 Modified) to measure the 0.01㎛ size of particle removal rate. It was tested on maximum airflow speed in normal room temperature and humidity conditions. The performance may vary in the actual living environment of customers.
→ Tested with Airmega Aim, 100, 150, 160, AP-1216L, AP-1512HH, AP-1512HHS, 200M, Icon, IconS, 230, 240, 250, 250 Art, 250S, 300, 300S, 400, 400S, ProX

299.97% of viruses, bacteria, fungi and pollen were verified to be removed from the air for Coway air purifiers which have Green True HEPA™ filter applied based on the Japan Food Research Laboratories(JFRL) testing according to JEM 1467 standard.

3Aerosol test conducted in a Biosafety level 3 laboratory with two Coway air purifier models, Coway Airmega 250 and 400 for removal of SARS-CoV-2 Aerosol by US based MRI Global, a not-for-profit laboratory and partner of US Department of Defense. The test was conducted in a 13.1ft3 chamber. Virus was aerosolized for 15 minutes and the product was turned on high for 2 minutes. Result showed each product effectively removed over 99.98% of the SARS-CoV-2 in 2 minutes. This is a result from a laboratory experiment condition and result may vary in different conditions. This result does not imply it kills SARS-CoV-2 or prevents the transmission of Covid-19. Coway Airmega 250S and 400S are identical to the tested models and has equal performance with an additional mobile connectivity function.

4The concentration of ammonia, acetaldehyde and acetic acid were proven to be removed within 30 minutes by FCG Research Institute, Inc. Human Life Science Lab. It is not a demonstration result in the actual use space. Not all odors and gases may be supported. → Tested with Coway Airmega 150, 160, AP-1512HH, AP-1512HHS, 400, 400S

5The coverage area of the air purifier is based on an area where the air cleaner can make two air changes per hour (ACPH). An air change per hour translates to how many times an air purifier can clean an area, assuming the height of a ceiling to be 8 ft, in one hour. Therefore ** means two air changes per hour means that the cleaner can clean the area once every 30 minutes and * means air changes per hour means that the air purifier can clean the area once every 60 minutes.
