Description
The Saunum Air L 13 Sauna Heater introduces a revolutionary approach to sauna heating by combining traditional sauna steam with advanced air climate equalizing technology. Designed to eliminate uneven temperature layers commonly found in traditional saunas, this innovative heater ensures balanced heat and oxygen levels throughout the sauna room.
In standard sauna environments, hot air accumulates near the ceiling while cooler air settles near the floor, often resulting in cold feet and uncomfortable breathing conditions. Saunum solves this issue with its patented air mixing system, which blends cooler oxygen-rich air from the floor with hot air from the ceiling and redistributes the balanced air throughout the sauna.
This results in a more comfortable sauna climate where heat and oxygen are evenly distributed from head to toe.
The Air L 13 also features an impressive 198-pound stone capacity, allowing the heater to produce soft, long-lasting steam when water is poured over the stones. Integrated Himalayan salt spheres further enhance the sauna atmosphere by releasing beneficial salt ions into the circulating air.
Finished in Nordic black steel, the Saunum Air L 13 blends modern Scandinavian design with advanced sauna engineering, making it ideal for larger residential saunas or professional wellness spaces.

Air Mixing Climate Equalizer System
The Saunum Air L heater features a patented air blending system designed to solve one of the biggest discomforts in traditional saunas.
The system works by:
• Drawing hot air from the ceiling
• Pulling oxygen-rich air from the floor
• Mixing both air streams inside the heater
• Distributing the balanced air evenly throughout the sauna
Benefits include:
• Eliminates cold feet
• Even heat distribution
• Improved breathing comfort
• Balanced oxygen levels in the sauna
This technology creates a sauna climate that is far more comfortable than traditional heaters.
Himalayan Salt Therapy System
The Air L 13 integrates a Himalayan salt reservoir inside the airflow system.
As air circulates through the heater, it passes over the salt spheres, distributing natural salt ions throughout the sauna.
Benefits include:
• Improved air quality
• Enhanced sauna wellness experience
• Optional aromatherapy compatibility
The tray is removable and allows easy replacement of salt spheres or addition of aromatherapy scents.
Stone Capacity & Steam Experience
The Air L 13 holds 198 pounds of sauna stones, creating a powerful thermal mass.
Large stone capacity provides:
• Softer and more comfortable heat
• Longer-lasting steam
• Improved heat retention
• Richer steam when water is poured over stones
Required:
198 lbs of sauna stones (6 boxes) sold separately.
