Two infrared saunas can look nearly identical but differ in wavelength, heater type, wood, EMF levels, and electrical requirements – differences that directly affect performance and comfort. Here's what to check before you buy.
Spectrum, Heaters, and Infrared Heat: The First Three Questions to Ask
Infrared saunas are often described as far infrared or full spectrum, and those terms refer to the wavelengths of infrared light the heaters produce. Full spectrum infrared saunas combine near, mid infrared, and far infrared light, while far infrared saunas rely solely on the longest wavelength. Either way, the heat reaches you differently than it does in a traditional sauna. Where a traditional sauna heats the surrounding air, infrared models direct energy straight at the body, so you can warm up without heating the entire cabin.
These differences matter beyond marketing language, since full spectrum and far-infrared models often use different heaters, heater placement, and price points. When comparing options, check exactly which wavelengths a sauna uses and where its heaters are positioned. Airpuria carries a wide selection of infrared saunas from premium brands, and browsing the indoor sauna collection is a good place to start comparing specifications across models.
Carbon Heaters, Ceramic Heaters, and Full-Spectrum Infrared Heaters
The heaters matter just as much as the type of infrared a sauna produces. Most models use carbon heaters, ceramic heaters, or a combination of both, and full spectrum infrared heaters add separate near-infrared emitters (small heating elements) alongside the far-infrared panels. Infrared sauna companies use different names for the same heater setups, so compare the spec sheets rather than the labels.
Heater placement affects how evenly the sauna heats your body. A model with heaters only behind the back will feel different from one with heaters covering the sides, back, and lower body. When comparing models, check heater type, panel placement and coverage, warm-up time, and operating temperature.
EMF Levels in an Infrared Sauna
EMF is another specification to evaluate when comparing infrared saunas. "Low EMF" is commonly used to describe the electromagnetic fields produced by heaters and electrical components, but the term isn't standardized, so actual readings can vary depending on how and where they're measured.
If EMF matters to you, look at the actual measurement rather than relying on the label alone. Check where the reading was taken and whether the sauna is third-party tested or certified for low EMF.
Wood, Placement, and Power: What the Room Requires
Cedar and hemlock are the main wood options across infrared sauna models, but wood type is only part of the construction. Also check how panels are assembled, what adhesives are used, and whether the manufacturer discloses VOC emissions.
Size and placement matter just as much. Check available space, door clearance, ventilation, and electrical requirements before ordering. We provide detailed specs for every sauna we offer, so use those along with photos to get a clear sense of materials and build quality before you buy.
Indoor and Outdoor Saunas: Choosing Where the Cabin Goes
Where you plan to put the sauna determines which model will work best. For an indoor sauna, start by checking the room, doorway width, floor, and space needed around the cabin. Confirm the room can handle the sauna's electrical requirements.
Outdoor models have a few additional considerations. You'll need a stable, level surface that can support the sauna, a suitable power connection, and a model built to handle your area's weather. Airpuria carries several options. Browse our indoor saunas or outdoor saunas based on where you decide to install it.
Electrical Requirements for a Home Sauna
Electrical requirements vary by model, so it's worth reviewing a few things before you order:
-
Circuit type: Some models use a standard 120V outlet, while others require a dedicated 240V circuit installed by an electrician.
-
Your panel's capacity: Send the sauna's specs to your electrician so they can confirm your home's electrical panel can support it.
-
Outdoor power access: For outdoor installations, the distance from the panel and the type of protection needed can affect installation cost.
What Installation Actually Involves
A little planning makes delivery and setup straightforward. Here are the things to confirm before the sauna arrives:
-
Delivery method: Services vary, so ask whether the sauna will be brought inside your home, and have a plan to move it the rest of the way if needed.
-
Assembly help: Some people assemble the sauna themselves, while others prefer to hire a professional for the install.
-
Fit and clearance: Measure the doorway, stairs, and the space where the sauna will be located. Compare those measurements with the model's dimensions and leave enough room around the cabin for heat to dissipate and for maintenance access.
Size also affects both the price and where you can install the sauna. A 2-person cabin may fit comfortably in a room where a 4-person model won’t.
Using Your Infrared Sauna Well
Infrared sauna sessions are widely used for relaxation and post-workout muscle recovery. The deep penetrating heat raises your body temperature and promotes sweating, so you come out of a session relaxed and refreshed. Regular sauna use has also been studied for cardiovascular and recovery benefits, and that's part of why many athletes keep sauna sessions in their routine.
How an Infrared Sauna Session Fits the Rest of Your Routine
Sauna time rewards the people who already sleep, hydrate, and train well, and it adds to those habits rather than replacing them. If you have a specific health concern, consult your physician before starting. For practical guidance on session length and temperature, see the sauna temperature guide.
Making Your Final Decision
With the health considerations covered, the rest comes down to comparing models on spectrum, heater layout, EMF, wood, placement, and power. If you're unsure where to start, fill out our sauna questionnaire, or contact us directly and our team can help you find the right fit.

Infrared Sauna FAQ
Are infrared saunas really worth it?
Infrared saunas are a worthwhile investment for anyone looking to incorporate heat therapy into a regular recovery or wellness routine. Unlike traditional saunas, infrared saunas heat the body directly rather than superheating the air, so sessions run at lower temperatures while still delivering relaxation, muscle recovery, and a healthy sweat.
What are the do's and don'ts of using an infrared sauna?
Stay hydrated before and after a session, read the manufacturer's guidelines, and consult your physician about any medical concerns before starting. Begin with shorter sessions and increase length and temperature gradually as your body adjusts.
What do 10 minutes in an infrared sauna do?
For many people, a short 10-minute session is a reasonable way to see how you tolerate the heat before building up. But the right starting point depends on your health, so check with your doctor first. Then, increase session length and frequency gradually as your body adapts.
How hot does an infrared sauna get?
Most infrared saunas run about 100–170°F, varying by brand and type. For an exact answer, check three numbers on the spec sheet: operating temperature range, warm-up time from cold, and panel surface temperature.
What is the best infrared sauna for home?
The right infrared sauna is sized to your space and performs well on spectrum, heaters, build quality, and EMF disclosure. Airpuria carries a wide selection of premium infrared saunas to fit a range of spaces and goals. Browse the collection or contact us for personalized guidance.
