Its development was supported by research in collaboration with Tallinn University of Technology, where thermal stratification and air movement in sauna rooms were analyzed. The goal of this research was to address the challenge of achieving uniform temperature at both head and foot levels.

Saunum’s patented Air-Blending System distributes the steam more evenly from head to toe, creating a soft and balanced climate within the sauna where it’s easier to breathe and healthy negative salt ions are added to the air.
