Experience the sauna as it was meant to be -a rejuvenating ritual that leaves you feeling better than when you entered. Without combustion of a wood stove, American electric saunas tend to have stale, harsh heat settled at head height. This can cause dizziness, while leaving feet cold. If you’ve ever “endured” a sauna session, listen up.
Saunum Air revolutionizes the experience by blending the hottest air from the ceiling with oxygen-rich air near the floor, creating a more even and comfortable environment. Say goodbye to hard-to-breathe air and burning steam. Breathe easy with the most versatile sauna heater on the planet.
With the external temperature sensor (now shipping free with Sauna Marketplace orders!) the Saunum Air gets hotter than ever. This is also our favorite heater for “slow-and-low” sauna sessions with high humidity and softer heat flowing over included Himalayan salt spheres and Aromatherapy cup at the base. Truly a world-class Spa experience.
Saunum Air is UL-approved for North America and ships daily out of greater Chicago. At Sauna Marketplace, every Saunum heater comes with specially selected rocks paired by Saunum, Wi-Fi enabled AirIQ Controller, Himalayan salt spheres, External Temperature Sensor, US-based support, and the latest integrated power box for simplified installation.

Saunum's unlike any other sauna. It's like a sanctuary for wellness and recovery. The moment I step into a Saunum I feel the warmth envelope my body. I start to feel stress and fatigue melt away.
You can really feel the difference thanks to its air blending system. Normally in saunas you can feel cold air at the bottom and much more hot air at the top.
Saunum's air blending technology allows all the air to blend evenly throughout the sauna and it really gives you the best experience you could possibly have without any cold spots or hot spots throughout the sauna. It allows you to breathe deeply and comfortably without experiencing too much fatigue.
Saunum has really transformed the way I experience sauna and has become a real integral part to my personal wellness routine. Saunum isn't just a sauna, it's the perfect sauna.
Electric saunas have one big problem.
Stratification.
Hot air rises and becomes stale without combustion from a wood fire. It’s not uncommon for an electric sauna to be 200 degrees at head height and under 100 degrees at foot height.
The best oxygen is low, while the best heat is high, where your head is most sensitive to heat.
Saunum Air is the only heater designed to solve heat stratification in saunas, providing even heat and oxygen levels throughout the space.
These state-of-the-art sauna heaters deliver a superior sauna experience, thanks to the patented air blending technology that mixes cool, oxygen-rich air from the floor with hot, oxygen-poor air from the ceiling. This technology ensures consistent temperature and oxygen levels throughout the sauna, improving comfort and enhancing your sauna sessions.
Saunum Air Series is available in elegant Nordic Black and polished Stainless Steel finishes, a nod to Scandinavian design aesthetics. They come with an adjustable valve for cool air intake, located 12 inches off the floor, and an output for blended air, ensuring perfect air circulation.
The Standard Saunum Air Series can accommodate rooms from 123 to 353 cu. ft., with each model designed for a specific range: the Saunum Air 5 for 106-212 cu. ft., the Saunum Air 7 for 177-282 cu. ft, and the Saunum Air 10 for 247-424 cu. ft. All models operate on 240VAC and are UL-certified, assuring safety and reliability.
The newest Saunum Air L series comes in three additional sizes. The Saunum Air 10 L 247-459 cu. ft, The Saunum Air L 13 for 317-565 cu. ft, or the Saunum Air L 15 for 459-741 cu ft.
*Contact us to calculate the impact of glass and uninsulated materials to best size your saunum.
Each Saunum Air model features a large stone capacity, ranging from 99 lbs to 231 lbs, producing softer, more even heat. The unique Himalayan Salt Reservoir, included with all models, releases healthful salt ions throughout the room, while an optional aromatherapy system enhances the sauna experience further. The Saunum Air Series also offers a Wi-Fi control option for convenience and customizability.
With the Saunum Air Series, you can experience the best of sauna bathing, delivered through innovative technology and elegant design. Transform your sauna sessions with Saunum – it’s all about the air you heat, feel, and breathe.
Note: Saunum Air Stainless body requires 30 inches of clearance on the sides and 20 inches in front of the fan:
Note: Black solid body Saunum Air requires 2" on each side and 20 inches in front of fan.
Saunum Air is the US version of the Saunum primary with UL listings. The tradeoff with UL listings is they require a maximum temperature of 194 degrees Fahrenheit, while European models can be programmed to 230f. However, with air movement and a more evenly heated sauna, you’ll find 194 degrees in the Saunum is a far more envigorating experience than any other heater on the market.
Compared to the solid black finish, the stainless steel rock basket distributes more air from the side of the heater, resulting in greater side clearances and higher minimum ceiling heights. The stainless steel options can handle larger spaces as well.
The minimum ceiling heights are to provide the minimum safety clearances and are not necessarily the physical limitations of the heater.
Yes, the Saunum AIRIQ WiFi upgrade lets you control the Saunum from your phone.
No, the Saunum distributes power to the fan.
We are working on pairing Saunum with our larger SaunaLife and Thermory barrel saunas. It may require a heat shield and other considerations. Please get in touch with us for details.

Before the introduction of the Saunum circulating air heater, Erkka Suominen, a long-time sauna and hockey enthusiast, had a traditional setup in his small apartment sauna with a Harvia Cilindro. "I knew there was room for improvement," Erkka expressed, highlighting his discontent with the uneven heat distribution in his sauna, forcing him to uncomfortably raise his feet to the upper platform for a smoother sauna experience.
In late 2022, Saunologia gave him an opportunity to test out the Saunum circulating air heater, which draws in hot air and moisture from the edge of the ceiling and blows it down to the floor, evening out temperature differences and moving the steam lower in the sauna. The experiment was carried out in November-December 2022, with the heater noticeably improving Erkka's sauna comfort. "Now, I'm able to spend a longer time in the sauna than before," he stated.
A month into the trial, Erkka found that he could create different sauna conditions with the Saunum heater by changing the combination of the sauna room's target temperature and fan strength. After the experiment, he also noted a significant reduction in temperature differences within the sauna, saying, "Before, the temperature difference from the ceiling to the footboard was more than 30 C, but now it's below 15 C."
Six months after the beginning of the experiment, Erkka was delighted with the Saunum air heater's performance. He remarked, "Saunum rocks and is in heavy use." Moreover, he found the Saunum remote control practical, allowing him to turn on the sauna from his phone.
In summary, the introduction of the Saunum circulating air heater significantly improved the sauna experience for Erkka, enhancing the heat distribution and allowing him to spend more time comfortably in the sauna.

I have had hard times to explain the effect of Saunum to my friends without actually making a demo with fan off and fan on. And then I have not heard anybody to say that there is not really enough difference 🙂 I took a pic of the lower end of sauna door being moist. I have not seen it in any other sauna, because hot moist air tends to go up and there is quite chilly air close to floor or even at any hight below heater’s upper point. I used to lift my feet up because of that. Until I had my Saunum heater installed.
Joseph Sherman –
Where do I start?! I would give Ben and Sauna Marketplace 10 stars if I could. I started out on the journey of researching saunas early this year and asked dozens and dozens of questions. Ben was extraordinary with his patience and detailed responses. During the process, someone told me about the Saunum heater which was just released in the states this year. This added another layer of questions as the Saunum heater is simply too big for the smaller barrels. I think Ben and I had a string of 50 emails back and forth before I made the purchase.
Once I made the decision to buy a Thermory 61 with a Saunum 7 heater, delivery was just as advertised. The customer service didn’t end there though…
Once the barrel was built, it was time to install and connect the heater. Turns out that the electricians that I hired messed up the wiring from the breaker box to the sauna and for a period of time, the heater would just not heat correctly. Before we discovered the electrician’s rookie mistake, Ben and his tech team stayed involved and helped me through the trouble shooting process. They were very patient and responsive.
Thank you Ben!!
Bob Halkdis –
First of all I want to say Ben was fantastic and very informative with all the products on his website.
He recommended the Saunum Air and this was the best decision for my 6×8 ft 7 feet high cedar sauna.
I got the 7kw with Wi-Fi and the power is plenty. I can take a dry sauna with no water on the rocks or add water and it becomes a steam room. The best part is when you turn the fan on and add water you can sit at lower level and not get too hot or cold. You don’t need to build an upper-bench with the fan system.
I have been in saunas most of my life and Saunum changes the game. It is built solidly and pumps out tons of heat.
I would recommend this unit big time Saunum hit it out of the park with the fan system.
Friends who normally would not use a sauna
Actually enjoyed ours and had no problems breathing or staying comfortable.
Before you buy a sauna heater make sure you talk to Ben about this unit and the benefits.
Verified owner Mark (verified owner) –
Amazing heater, definitely worth the premium. The loyly experience is entirely different with the fan off and on. With the fan on, your body can get very hot but the heat feels less harsh. With the fan off you have a classic sauna. I recommend running the fan for a few minutes after pre-heating the room to get the entire room up to temp, instead of just the top half. That feature is not possible with a regular electric setup unless you have a solidly designed and robust forced downdraft ventilation system. It is truly a unique sauna experience.

Powerful and evenly distributes the heat. 40 Celsius outside and 200+ degrees in there
