Saunum · Made in Estonia · UL listed
The climate-equalizing heater that fixes electric sauna stratification - in the solid Nordic Black body with just 2" side clearances.
Electric saunas run 200F at your head and under 100F at your feet. The Saunum AIR pulls that scorching ceiling air down, blends it with oxygen-rich floor air, and returns soft, even heat - with AirIQ Wi-Fi control, Saunum-paired stones, Himalayan salt spheres, and an external temperature sensor all in the box.

A quiet fan draws the hottest air off the ceiling and mixes it with cooler, oxygen-rich floor air. Saunologia’s long-term reviewer measured his ceiling-to-floor spread drop from over 30C to under 15C - even heat where you actually sit and breathe.
Thermal engineer Andrus Vare designed Saunum around the soft, stone-heavy heat of historic Estonian smoke saunas, with stratification research done alongside Tallinn University of Technology. Designed and built in Estonia.
The AIR series is the Saunum we reach for in smaller rooms, and the solid Nordic Black body needs only 2" to combustibles at the sides with rear-against-wall placement - so it fits compact rooms and barrel saunas the open basket cannot. 110 lb of stone still delivers long, soft steam.
Classic Nordic, steam-rich, mild relaxing, salt-ion, and aroma sessions - set temperature, fan speed, and intake valve from the included AirIQ Wi-Fi controller or the free Saunum app, with three programmable presets.
Sauna Marketplace ships every Saunum with paired stones, the AirIQ Wi-Fi controller, Himalayan salt spheres, an external temperature sensor, and the latest prewired power box for a simpler install.
The Bens have worked hand-in-hand with the Saunum team since the brand first reached the US, run Saunum heaters in their own saunas, and have been part of Saunum pilot projects, testing, and R&D tuned for the US market. When you have a sizing, install, or steam question, you are talking to the people who helped shape the US lineup.
