Harvia Saunum AIR 7 Sauna Heater Stainless - 4745090017908

Saunum’s patented air blending system improves the sauna experience by mixing heat and steam from the ceiling with cooler, oxygenated air from the floor, balancing room temperatures by over 60% for a more comfortable, breathable environment. This eliminates the common issue of extreme temperature variation, where the ceiling can exceed 200°F while the floor remains under 100°F. The climate equalizing system ensures consistent temperature and oxygen levels throughout, enhancing your sauna session for longer, more intense sweating. also enriches the air with Himalayan salt ions for health benefits like decongestion and inflammation reduction, and offers aromatherapy options to elevate relaxation. With six customizable sauna styles—Russian Banya, Finnish Sauna, Estonian Sauna, Yoga Sauna, Salt Sauna, and Aroma Sauna—you can adjust airflow, temperature, and steam to create the perfect sauna experience.  

What our Experts Think

• Revolutionary air-mixing sauna experience
  The Saunum AIR 7 stands out for its patented climate equalizer technology, blending hot ceiling air with cooler floor air to eliminate “hot head, cold feet” imbalance and deliver more uniform heat throughout the room.
• Consistently comfortable heat profile
  Unlike traditional heaters, it creates a softer, more breathable sauna environment, allowing longer sessions without the harsh temperature layering typical in standard electric units.
• Ideal for medium-sized premium saunas
  Designed for rooms around 212–282 cu. ft., the 6.4kW output is optimized for efficient, even heating rather than raw intensity.
• Exceptional steam quality (large stone mass)
  Supports up to ~132–154 lbs of stones, producing rich, gentle, long-lasting löyly (steam bursts) with superior thermal stability.
• Premium wellness-focused features
  Includes a Himalayan salt reservoir system, designed to distribute salt ions through airflow for an added wellness and spa-like experience.
• Modern stainless steel build
  Scandinavian-inspired stainless steel construction delivers a high-end, architectural look suitable for luxury sauna builds.

Q&A

Maintenance Tips

• Re-stack & replace sauna stones (6–12 months): Uses up to ~154 lbs of stones—keep them loosely arranged to support airflow and stable heat distribution.
• Maintain proper stone airflow: Do not overpack; the Saunum system relies on air circulation for even heat and consistent climate balance.
• Clean air circulation components regularly: The built-in air-mixing fan system should stay free of dust and obstructions for optimal performance.
• Use clean water only: Avoid oils, salt, or chemicals on stones to prevent residue buildup and protect heating elements.
• Check heating elements periodically: Ensure stones are not pressing directly on elements to prevent overheating or premature wear.
• Wipe stainless steel surfaces: Remove moisture and mineral stains to maintain corrosion resistance and premium finish.
• Monitor salt reservoir (if used): Keep Himalayan salt modules clean and properly positioned to maintain airflow ionization benefits.
• Ensure proper ventilation & sauna sizing: Maintain correct room volume range (approx. 212–282 cu ft) for efficient, balanced operation.
