Description
The Saunum Air L 15 Sauna Heater redefines the traditional sauna experience with its innovative patented air blending technology and advanced climate equalizing system. Designed to eliminate the common sauna problem of uneven heat distribution, this premium heater ensures consistent warmth and oxygen levels from head to toe.
Traditional sauna heaters often create hot air near the ceiling while leaving cooler air at the floor, resulting in uncomfortable temperature differences. Saunum solves this issue with a unique air mixing system that blends cooler oxygen-rich air from the floor with hotter air from the ceiling and redistributes it evenly throughout the sauna.
This revolutionary approach creates a more balanced climate, making the sauna experience more comfortable, breathable, and relaxing.
With its massive 198-pound stone capacity, the Air L 15 produces exceptionally soft, long-lasting steam when water is poured over the stones. The heater also includes a Himalayan salt reservoir, allowing salt ions to circulate throughout the sauna for added wellness benefits.
Finished in Nordic black steel, the Saunum Air L 15 combines elegant Scandinavian design with cutting-edge sauna engineering, making it an ideal centerpiece for larger residential or commercial sauna spaces.

Air Mixing Climate Equalizer System
The defining feature of the Saunum Air L heater series is its patented heat equalizing system, which dramatically improves sauna comfort.
The system works by:
• Drawing hot air from the sauna ceiling
• Pulling cooler oxygen-rich air from near the floor
• Blending the air together inside the heater
• Redistributing the mixed air evenly throughout the room
This process eliminates temperature layering and ensures consistent heat throughout the sauna.
Benefits include:
• No more cold feet
• More comfortable breathing
• Balanced heat distribution
• Improved oxygen circulation
Himalayan Salt Therapy System
Inside the heater’s air circulation system sits a Himalayan salt tray containing natural salt spheres.
As the blended air passes through the salt tray, salt ions are carried throughout the sauna, enhancing the sauna environment.
Benefits may include:
• Improved respiratory comfort
• Cleaner sauna air
• Enhanced wellness experience
The tray is removable and can also support optional aromatherapy scents.
Stone Capacity & Steam Experience
The Air L 15 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.
