Patented Climate Technology

Air-Mixing System for Balanced Sauna Heat

Saunum’s patented air-blending technology mixes rising hot steam with cooler air from the lower part of the sauna and redistributes it evenly throughout the room. This eliminates temperature layering and creates a softer, oxygen-rich sauna climate that is far more comfortable than traditional setups.

Salt & Aroma Therapy

Himalayan Salt Ion and Aromatherapy System

Integrated Himalayan salt balls release beneficial salt ions into the circulating sauna air, helping support respiratory health and skin wellbeing. The system also allows aromatherapy oils to blend gently with steam for a clean and controlled fragrance experience.
