Best Low-EMF Infrared Saunas for Home Use
Written by Maria Almeida
EMF specifications have become an important comparison point for many people shopping for an infrared sauna. Manufacturers commonly use terms such as “low EMF” and “ultra-low EMF,” but those labels do not always mean exactly the same thing from one product to another.
A useful comparison therefore goes beyond the marketing label. Published measurements, measurement distance, heater placement, sauna size and the manufacturer’s documentation can all provide important context.
In this guide, we explain what low EMF means in the context of infrared saunas and compare two models from our current selection: the Dynamic Cordoba Infrared Sauna, for which the manufacturer states under 3 mG at 6–8 inches, and the KUNSANA 2–3 Person Corner Infrared Sauna, for which the manufacturer states an Ultra-Low EMF specification of 0–1 mG.
Looking for a low-EMF infrared sauna?
Two models in our current selection are particularly relevant.
The Dynamic Cordoba Infrared Sauna is a 2-person cabin for which the manufacturer states under 3 mG at 6–8 inches.
The KUNSANA 2–3 Person Corner Infrared Sauna is designed for 2–3 people, and the manufacturer states an Ultra-Low EMF specification of 0–1 mG.
These are manufacturer-stated measurements and may not be directly comparable, since testing distance, location and methodology can differ between brands. When EMF is a priority, compare the manufacturer's current numerical measurements and the conditions under which those measurements were taken.
Low-EMF Infrared Saunas to Consider
The two models below both include EMF-related positioning, but they are different in capacity, layout and controls.
The Dynamic Cordoba is a 2-person traditional cabin. The KUNSANA 2–3 Person Corner model is a larger corner-style sauna with a published Ultra-Low EMF specification of 0–1 mG.
Dynamic Cordoba DYN-6203-01 Elite Ultra Low EMF Infrared Sauna

Both models provide a manufacturer-stated numerical EMF measurement in the product information currently available to us: the Dynamic Cordoba is stated as under 3 mG at 6–8 inches, and the KUNSANA 2–3 Person Corner model is stated as 0–1 mG.
These manufacturer measurements may not be directly comparable, since testing distance, location and methodology can vary between brands. That difference also does not by itself determine which sauna is the better fit for a particular home. Capacity, dimensions, heating configuration, electrical requirements, controls and installation space should also be considered.
What Does EMF Mean?
EMF stands for electromagnetic field.
Electrical devices and wiring can produce electromagnetic fields, and infrared saunas contain electrical components such as heating panels, controls and wiring.
Because users sit relatively close to the heating system, manufacturers often include EMF information in infrared sauna specifications.
For comparison purposes, the most useful information is usually a specific measurement accompanied by details about where and how the measurement was taken.
What Does Low EMF Mean in an Infrared Sauna?
“Low EMF” is commonly used as a product description, but it should not be treated as a universal technical threshold unless the manufacturer defines the measurement criteria.
One manufacturer may describe a sauna as low EMF without publishing a specific numerical range, while another may provide measurements in milligauss.
That is why shoppers should look beyond the label itself.
When available, review the numerical measurement, the distance from the heating panel, the location inside the cabin and any testing information provided by the manufacturer.
Low EMF vs. Ultra-Low EMF
The terms “low EMF” and “ultra-low EMF” are frequently used in infrared sauna marketing, but terminology can vary among manufacturers.
An “ultra-low” label should therefore not automatically be interpreted as a standardized category across the entire sauna industry.
A numerical specification can make products easier to compare, provided the measurement conditions are also understood.
On this page, the Dynamic Cordoba's manufacturer states under 3 mG at 6–8 inches, while the KUNSANA 2–3 Person Corner model's manufacturer states an Ultra-Low EMF specification of 0–1 mG.
What Is mG?
mG stands for milligauss, a unit commonly used to express magnetic-field strength in product specifications and EMF measurements.
When an infrared sauna manufacturer provides an mG figure, the number should be considered together with the measurement conditions.
Distance matters. A reading taken very close to an electrical component may differ from a reading taken at the position where a user normally sits.
For that reason, comparing two numbers without knowing how they were measured may give an incomplete picture.
Why Measurement Distance Matters
EMF readings can vary depending on where the measurement is taken.
In an infrared sauna, measurements may differ near a heating panel, wiring or control component compared with another part of the cabin.
When reviewing a manufacturer's EMF specification, look for information about the measurement location and distance.
If those details are not published, avoid assuming that an EMF number from one sauna was measured under the same conditions as a number from another sauna.
Heating Panels and EMF
Infrared sauna heating systems contain electrical components, so heater design and placement are relevant when reviewing EMF information.
Both models featured on this page use carbon infrared heating panels.
The Dynamic Cordoba uses seven low-EMF carbon heaters, while the KUNSANA 2–3 Person Corner model uses eight far-infrared panels.
Panel count alone does not determine EMF level. Heater construction, wiring, electrical design, measurement distance and other factors can influence published readings.

Does Lower EMF Automatically Mean a Better Sauna?
EMF is one specification among many.
A lower published EMF number should not cause shoppers to ignore capacity, cabin dimensions, heater placement, electrical requirements, construction, controls, warranty information and installation needs.
The most appropriate sauna is one whose overall specifications fit the intended space and use.
If EMF is particularly important to your buying decision, prioritize clear manufacturer documentation and comparable measurements rather than relying solely on labels such as “low” or “ultra-low.”
Capacity and Cabin Size
The two featured models also differ substantially in capacity.
The Dynamic Cordoba is designed for 2 people, while the KUNSANA 2–3 Person Corner sauna is designed for 2–3 people.
A smaller cabin may make more sense when floor space is limited. A larger cabin may be preferable for couples or shoppers who want additional interior room.
For capacity-specific guidance, see our guides to 1-person infrared saunas and 2-person infrared saunas.
Electrical Requirements
Electrical specifications should always be verified before purchasing an infrared sauna.
The Dynamic Cordoba lists a 120V standard outlet.
The KUNSANA 2–3 Person Corner model lists 1760W on a 120V connection. Verify the manufacturer's current electrical specifications before installation rather than assuming its requirements based on capacity or heater count.
Follow the manufacturer's installation instructions and consult an appropriately qualified professional if there is uncertainty about the electrical setup.
Smart Controls and Other Features
EMF may be the main reason someone reaches this guide, but controls and convenience features can still affect everyday use.
The Dynamic Cordoba includes Bluetooth audio and chromotherapy.
The KUNSANA 2–3 Person Corner model includes a dual-control LCD, chromotherapy, a Bluetooth speaker and an LED reading light.

Frequently Asked Questions
What does low EMF mean in an infrared sauna?
It generally indicates that the manufacturer is positioning the sauna as producing relatively low electromagnetic-field readings. However, there is no single meaning that should automatically be assumed from the label alone. Look for numerical measurements and measurement conditions when available.
What does ultra-low EMF mean?
Ultra-low EMF is another term used by manufacturers to describe certain products. Because terminology may vary, a numerical measurement is more useful for comparison than the label by itself.
What does 0–1 mG mean?
It indicates a magnetic-field measurement expressed in milligauss. For the KUNSANA 2–3 Person Corner model featured here, the manufacturer states an Ultra-Low EMF specification of 0–1 mG. Measurement conditions should still be reviewed.
Is the Dynamic Cordoba ultra-low EMF?
Yes. The product information currently used on this site describes the Dynamic Cordoba as Ultra Low EMF, with the manufacturer stating under 3 mG at 6–8 inches.
Should EMF be the only factor when choosing an infrared sauna?
No. EMF information can be one comparison point, but capacity, dimensions, heating configuration, electrical requirements, construction, controls, warranty and installation suitability should also be evaluated.
Final Thoughts
Low-EMF terminology can be useful when comparing infrared saunas, but the label itself provides only part of the information.
The Dynamic Cordoba is a 2-person sauna for which the manufacturer states under 3 mG at 6–8 inches, while the KUNSANA 2–3 Person Corner model is stated by its manufacturer as 0–1 mG and provides 2–3 person capacity with a corner-style design.
These manufacturer-stated measurements may not be directly comparable, since testing conditions can differ between brands.
When EMF is a priority, look for numerical measurements and information about how those measurements were obtained. Then consider those figures alongside the sauna's capacity, dimensions, heating system, electrical requirements and controls.
