Greeting

Hello, I am Tae-Woong Cha, CEO of
ClearChang is a company that integrates air purification and ventilation technology to create healthier, more sustainable indoor environments.
A window is not merely a boundary between inside and outside.
It connects people and links the world together.
And we asked ourselves
“Can a single window protect the health of a family?”
That question was the beginning of ClearChang.Through technology, we aim to create ‘sustainable air’ and
build a world where clean air, intelligent automation, and environmental responsibility coexist.Technology that connects the world transparently — that is ClearChang.
