Hyungjoo Kim
Hyungjoo Kim is a dentist-turned-inventor and the founder and CEO of Carepod, a wellness hardware company built around a humidifier you can actually take apart and sterilize. Frustrated that every humidifier he bought for his sick daughter grew mold and bacteria within weeks, he engineered a filter-free, three-part, stainless-steel design that can be boiled clean and comes out 99.9% germ-free. Founded in South Korea in 2015, Carepod's award-winning humidifiers now sell across the United States, Canada, Australia and beyond, and have been featured by Entrepreneur, Forbes and Health Magazine.

Growing up in smog-choked Shanghai and arriving to California's startling blue skies as a teenager, he turned personal contrast into a global mission. Clarity's tissue-box-sized solar-powered sensors have recorded over 500 million measurements, informed London's low-emission zones, and earned Lu a spot on TIME's 100 Most Influential Climate Leaders of 2025.
