Saunum AIR and AIR L Pro | Air Circulating Sauna Heaters for US and Canadian Market

(5 customer reviews)

You should come out of the sauna feeling better than you did before.  In traditional smoke saunas of Finland and Estonia, that’s how it was.  Today, people “endure” the sauna for just 10-15 minutes at a time.  That’s because stale heat in electric saunas settles at head height, making you feel dizzy while your feet stay cold.

Saunum blends the hot air from the ceiling with oxygen rich air near the floor and creates a more even, comfortable environment.

Say goodbye to hard-to-breathe and burning steam, and join the thousands of customers around the world who say they would never go back.  Saunum Air is UL-approved for North America and ship daily out of greater Chicago.

The built-in Himalayan salt reservoir, WiFi-enabled AIRIQ controller, and thoughtful design will deliver optimal conditions that hit every sense with an enveloping warmth.

Billy's Saunum Review:

You Deserve The

Saunum Experience.

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.

Don't Settle For a Hot Room

Saunum Air Flow

Electric saunas have one big problem.


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.

The World’s Most Advanced Sauna Solution

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.

Calculating You Sauna Volume to Size Your Saunum Air and Air L Heater

Selecting the right heater for your sauna involves considering the room's volume and the materials used in its construction. Materials like glass, tile, brick, concrete, or stone, which do not retain heat well, necessitate a more powerful heater.

Step-by-Step Calculation:

  1. Determine Room Volume: Calculate the room's volume by multiplying its height (Z), width (X), and length (Y) in feet. This gives you the basic cubic volume of your sauna.

  2. Account for Specific Materials: If your sauna includes walls made of glass, tile, brick, concrete, or stone, you need to adjust the volume calculation. First, calculate the total square footage of these materials by adding up their surface areas. Then, for each square foot of these materials, add an additional 3.9 cubic feet to the room's volume. This compensates for their lower heat retention.

  3. Adjust for Log Walls: If your sauna has log walls, take the room's volume from step 1 and multiply it by 1.5. This accounts for the insulating properties of logs.

  4. Final Volume: The resulting figure from these calculations represents the sauna's adjusted volume, which you can use to select the appropriate heater size. If your calculated volume is between two heater sizes, opt for the larger size to ensure adequate heating.

Sauna Room Heights:

  • Standard sauna room heights range from 83 to 91 inches.
  • For installations involving the Saunum Air L climate device, the minimum ceiling height is 71 inches.

Refer to Table 1 in the provided pages (12-13) for optimal sauna sizes for the Saunum Air climate device. This guide ensures you choose a heater with sufficient output for your sauna's specific conditions and materials.

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.  

Yes, there is a Saunum option for most indoor and outdoor Auroom and SaunaLife saunas.  Please get in touch for options.

There’s a Saunum dealer in Australia:

We’ll have to stop free shipping (a $500 value) in the coming weeks.  Moreover, the stock is tight in North America and we are unsure when more will arrive.  We recommend getting your orders in now for fast and free shipping.

The Saunum Air is specific to the North American market.  In the UK, you are looking for a Saunum Primary – get ahold of Lewis at The Cedar Sauna Company for more info.

Saunologia's Saunum Review

Saunologia is a Finnish sauna design company that helps customers around the world to secure healthy, sustainable and functional sauna designs. It was founded by Dr. Lassi A Liikkanen and is based in Finland. It features some of the best information about sauna design available in print and online. Sauna Marketplace is not affiliated with Saunologia.

Learn more about Liikkanen's work by reading his highly acclaimed The Secrets of Finnish Sauna Design.

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.

    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!!

    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.

    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.

About Saunum
Like Sauna Marketplace, Saunum believes that the sauna should be more than a hot room.  They believe the sauna shouldn't have to be 'endured', and that you should leave the sauna feeling better than you entered. The Founders knew this could be accomplished, as they grew up in smoke saunas that are common in Finland and Estonia.  Smoke saunas had lower temperatures, more humidity, and much more even temperatures throughout. Their experience also showed them the importance of oxygen in the hot room, and how low oxygen would make you feel depleted after the sauna. They worked with Universities in Estonia to develop simple, patented solutions that take the hottest air from the ceiling of a sauna and blend it with oxygen rich air at the floor level. The result is the most comfortable, invigorating sauna experience on the market. Also like Sauna Marketplace, Saunum likes to back everything up with data.  The big picture is develop 'smart sauna' technology that blends the perfect sauna environment depending on the outcome desired by the user, and personal preferences. Saunum heaters in North America include the Saunum Air and Saunum Air L series.  The Saunum Air L keeps the rocks lower and is better for most medium to large sauna spaces. We also have the Saunum AirSolo for those who want the Saunum air circulating system with another another electric heater or even a wood stove. Reach out to your Sauna Marketplace representative today for pairing your new or existing hot room with the perfect Saunum product.  Trust us, it's worth it!
