Saunum Air L 13 – Stainless Steel
Overview
The Saunum Air L 13 is a unique heater with a sauna climate regulating system that is ideal for creating an extraordinary sauna session in a more intensively used sauna. The large stone volume of the Saunum Air L 13 and the patented air-blending system ensure exceptional steam that is soft and long, and evenly distributed throughout the sauna.
Key Features
- Revolutionary Air Mixing Technology – No more cold feet! No other sauna heater has Saunum's patented air blending system, which mixes cooler, oxygen-rich air from the floor with hot, oxygen-poor air off the ceiling and distributes it throughout the room for a more even temperature and better breathability. Saunum ensures that heat and oxygen are more consistent from head to toe.
- Scandinavian Design – With its elegant stainless steel finish, Saunum combines contemporary Scandinavian design and premium-quality materials.
- Massive Stone Capacity – Stones are the heart of a Nordic sauna. Greater stone capacity results in softer, more even heat, and can produce more luxurious steam. The Air L boasts a massive 190 pound stone capacity (required 6 boxes sold separately).
- Himalayan Salt Reservoir – Himalayan Salt Spheres are positioned within the air stream so that salt ions are propelled throughout the sauna to deliver health benefits more effectively.
- Dry your Sauna – Go ahead, toss water onto the rocks! Saunum is engineered for water-tossing, and when you're done enjoying the steam, the patented fan system will conveniently help dry your sauna.
- UL Certification – Safety and reliability are priorities at Saunum, and each product is engineered to exceed strict UL standards.
- Available Aromatherapy – Add another sensory layer with Saunum's optional aromatherapy system, which infuses aroma into the steam to further transform your experience.
- For sauna rooms from 424 to 565 cu. ft.

About Saunum
Even heat, floor to ceiling

The L 13 has the muscle for my big room and still keeps every seat the same temperature thanks to the circulation. Impressive engineering. Sauna Co. arranged freight smoothly and confirmed my electrical needs in advance.
The even-heat tech transformed our large sauna from patchy to perfect. Build quality is superb. Sauna Co. kept me updated from order to delivery.
We seat eight and everyone's comfortable wherever they land, which never happened with our old heater. Soft, full steam too. Delivery hit the promised window.
A higher-output L-series unit needs proper service and a controller — support made that clear before I bought. Once running, the even heat is sublime. Packed and shipped beautifully.
Uniform, gentle heat that fills a large space without scorching the top bench. Quiet circulation, gorgeous stainless. Communication was excellent throughout.
