Saunum is an Estonian sauna technology company that solves the biggest comfort problem in traditional saunas: uneven heat distribution. In a typical sauna, the air at ceiling height can reach 200°F while the air at foot level sits below 100°F — meaning hot, harsh air in your face and cold feet on the floor. Saunum's patented air-blending system (the Climate Equalizer) draws hot steam from the ceiling, mixes it with cooler, oxygen-rich air near the floor, and redistributes an even, breathable steam throughout the entire room. The result is temperature equalized by more than 60%, softer steam that's easier on the lungs, and sessions you can enjoy longer. Every Saunum heater includes a built-in Himalayan salt reservoir that projects ions into the air, plus WiFi control through the AirIQ app. We carry the full Saunum lineup: electric heaters, standalone AirSolo climate devices, pre-assembled outdoor sauna cabins, and accessories. Free shipping on all Saunum products, 0% APR financing available.

The Saunum Air series are wall-mounted electric sauna heaters with the Climate Equalizer built in. Unlike traditional heaters that simply radiate heat from stones, Saunum Air heaters actively circulate and blend the air inside your sauna for an even temperature from floor to ceiling. All models include a built-in Himalayan salt reservoir and are WiFi-compatible with the AirIQ controller.
Air 5 (4.8 kW) — The compact model for smaller home saunas. Provides the full air-blending experience in a lower power output for rooms that don't need heavy heating capacity. 240V.
Air 7 (6.4 kW) — The mid-range model for standard home saunas. The most versatile option in the Air lineup, balancing power with room coverage. 240V.
Air 10 (9.6 kW) — The high-power model for larger saunas. Enough output for spacious home or light commercial use. 240V.
Air Perfect — A package variant with optimized components for a complete ready-to-install setup.
Each Air heater is available as heater only (you supply the controller and stones) or as a complete package with the AirIQ WiFi controller and olivine sauna stones included. The complete packages are the better value for new builds. We also carry the Air L Package — an extended version with increased power and capacity for larger sauna rooms.

Already have a sauna heater from another brand? The AirSolo is Saunum's standalone climate device that pairs with any sauna heater — Harvia, HUUM, or any other brand — to add Saunum's air-blending technology to an existing sauna. The AirSolo blends hot air and steam from the ceiling with cooler air at the floor, equalizing the temperature and steam distribution throughout the room. Air passes over Himalayan salt spheres to project ions for respiratory and skin benefits. No heater replacement required — the AirSolo is a supplementary device. Shop all air circulating systems.
AirSolo Wall — An in-wall mounted version with adjustable height. Installs flush into the sauna wall for a clean, integrated look. Best for new builds or renovations where you can cut into the wall cavity.
AirSolo 70 — A freestanding unit at 75" height. No wall modification required — simply place and connect. Weighs approximately 66 lbs.
AirSolo 80 — A freestanding unit at 85" height. The taller option for saunas with higher ceilings where the blending intake needs to reach closer to the ceiling.
AirIQ WiFi Controller — Saunum's programmable smart controller with three preset programs and WiFi connectivity for remote control from the Saunum app. Controls temperature, timer, and delayed start. Included in all Saunum complete heater packages; available separately for heater-only buyers.
Auto Leil — An automated water and scent dispenser that mounts to your Saunum heater. Delivers precise, timed doses of water (and optional essential oil) onto the sauna stones for consistent steam without manually ladling water. Customize steam intensity and interval through preset steam types. One of our most popular Saunum accessories — pulls strong search traffic for automated sauna water dispensers.
Safety Rail — A protective rail for Saunum Air series heaters. Prevents bathers from accidentally contacting the hot heater surface. Recommended for family saunas or commercial installations.
Olivine Sauna Stones (33 lbs) — Saunum's own olivine diabase stones, rounded and sized 2"–4" for optimal steam production. Manufactured from premium raw stone for consistent heat retention and clean steam.
Harvia and HUUM are excellent heater manufacturers, but they're conventional heaters — they heat stones, you add water, and heat rises to the ceiling while the floor stays cold. Saunum's patented Climate Equalizer actively circulates air to eliminate that temperature stratification. The result is a fundamentally different sauna experience with more even heat, softer steam, and better breathability. If sauna comfort and air quality are your top priorities, Saunum is in a class of its own. If you want the widest heater selection and lowest entry price, Harvia has more options. If you want design-forward aesthetics, HUUM is the competition. Read our full Harvia vs. Saunum comparison for a detailed breakdown.
Yes — that's exactly what the AirSolo is for. The AirSolo is a standalone climate equalizer that pairs with any brand of sauna heater. You don't need to replace your Harvia, HUUM, or other heater. The AirSolo installs as a supplementary device and handles the air blending independently. Choose the AirSolo Wall (in-wall), AirSolo 70 (freestanding 75"), or AirSolo 80 (freestanding 85") based on your sauna's layout and ceiling height.
The Air 5 (4.8 kW) is for smaller rooms, the Air 7 (6.4 kW) covers standard home saunas, and the Air 10 (9.6 kW) handles larger or commercial spaces. Use our sauna heater sizing calculator to match the right kW to your sauna's cubic footage. When in doubt, size up — a slightly oversized heater heats faster and runs at lower effort.
Yes — all Saunum Air electric heaters require a dedicated 240V circuit and professional installation by a licensed electrician. Saunum does not offer a 120V option.
