Saunum Air 5 Sauna Heater – Stainless Steel
Description The Saunum Air 5SS Sauna Heater (Black) is built for sauna owners who want comfort that feels consistent from head to toe. Traditional saunas often run very hot near the ceiling while staying noticeably cooler at floor level. Saunum’s patented air mixing technology pulls hot air from above, blends it with cooler, oxygen-rich air from below, and redistributes it throughout the room. The result is a more even temperature, more comfortable breathing, and a better overall session. This model combines a clean Nordic black steel finish with practical performance features: a 132 lb stone

Description
The Saunum Air 5SS Sauna Heater (Black) is built for sauna owners who want comfort that feels consistent from head to toe. Traditional saunas often run very hot near the ceiling while staying noticeably cooler at floor level. Saunum’s patented air mixing technology pulls hot air from above, blends it with cooler, oxygen-rich air from below, and redistributes it throughout the room. The result is a more even temperature, more comfortable breathing, and a better overall session.
This model combines a clean Nordic black steel finish with practical performance features: a 132 lb stone capacity for softer heat and richer steam, plus an integrated Himalayan salt system that circulates salt ions through the sauna air. It’s sized for sauna rooms from 106 to 212 cubic feet, is UL-listed, and is engineered for water-tossing steam sessions.
Important: This heater requires a compatible control and 132 lbs of sauna stones (4 boxes) sold separately.

Climate Equalizing Air Mixing System
Saunum’s climate equalizer helps reduce the common “cold feet / hot head” effect by balancing heat and breathability across the sauna.
The system:
• Draws hot air from the ceiling zone via telescopic intake
• Pulls cooler air from the lower area
• Blends both air streams inside the heater
• Outputs mixed air back into the sauna for a more even experience
What you feel:
• More consistent heat from floor to ceiling
• More comfortable breathing and longer sessions
• Better steam circulation throughout the room
Himalayan Salt Therapy System
The Air L5 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.
