Sauna Buyers Guide

Sunlighten offers three different sauna collections: Solo, Signature and mPulseWith so much information on the internet, researching infrared saunas can be confusing. There are hundreds of saunas online that look similar at various price points, with widely varying claims of health benefits. The truth is, there are many factors to consider when buying a sauna. Read on to take the guess work out of your own sauna purchase!


EMF Technology: Look for infrared saunas that have extremely low Electro Magnetic Fields (EMF). Check to make sure your sauna has third-party tested results on its EMF levels. Learn more about EMF.

Non-toxic materials: Your new sauna should be made from 100% non-toxic materials, inside and out. This means everything from carbon heater panels that are heat-sealed (ensuring no wires or glues that may give off gas) to the wood used in the structure of the sauna. Sunlighten saunas use Basswood, which is the only wood not listed on the toxic wood chart.

Safety Certified: Has your sauna been through third-party testing to ensure safety? Make sure it has an electrical certification to ensure it meets safety and performance standards. You can check this by looking for a safety agency mark on the product. Without this mark, there is no proof that a product passes electrical safety standards.

Sauna Heater Effectiveness

Look for a Carbon Heater and check Heater Emissivity: Sauna heater emissivity is the most important element to consider: it determines how efficient infrared heat is conducted and emitted. This is the active ingredient needed to achieve the known health benefits of infrared therapy. To get the maximum benefit from your infrared sauna, make sure you are purchasing a sauna with a heater that is proven effective at delivering the highest concentration of infrared. Always ask for emissivity data before purchasing.

Carbon heaters (rather than ceramic or ceramic/carbon blends) emit infrared wavelengths at a more constant temperature through large panels creating an even distribution of comforting infrared heat throughout the sauna. Here at Sunlighten, we tested the carbon/ceramic concept years ago and found no advantage to blending the materials (View Study). Hotter is not always better – with hotter temperatures you will spend less time in the sauna, making your sessions less effective. What truly matters is how effective the sauna heaters are at conducting infrared heat!

Sauna Durability & Value

Like the old adage says: You get what you pay for.

Inexpensive saunas are made with low-end materials, offer less effective sauna health benefits and can lead to costly repairs or replacement down the road. Many bargain saunas are assembled using thinner planks and wood with knots in it, like hemlock, spruce and pine, which makes the cabin less durable. Saunas made from thicker, more quality wood such as basswood or cedar will stand up over time.

Cheaper saunas are also less efficient at providing the valuable health benefits of saunas. Rather than simply heating the ambient air to draw out toxins, far infrared therapy should heat your core to expel these toxins (view Study). As a result, you get a truly deep, productive sweat where toxins reside, at the cellular level. If an infrared sauna is only emitting heat that is 50% infrared and 50% hot air, you will not get an increase in core temperature or the benefits of detoxification. Most low-end saunas are less than 70% efficient at producing infrared heat. Look for proven emissivity of 95% and above (view Sunlighten Emissivity Data).
