Home / About Us
We are YO, born in 2019. By observing the small details in life, we carefully understand the needs of our closest family members and friends, and activate the designer's instinct to discover and solve problems. This is what we value. If you can feel the beauty of life through our products, it will be our greatest honor.


YO sterile thermal evaporative humidifier was developed by a team led by Japanese engineer Tomoya Yamaguchi. Committed to delivering the concept of healthy humidification to every family.


Our philosophy is to bring technology into life and health into families. We develop household appliances with the goal of improving product performance and creating a comfortable life.


We hope to re-understand the impact of air humidity on the human body and come up with the most convenient way to achieve the best temperature and humidity conditions.
