Ultra-Low EMF in Infrared Saunas: Meaning & Measurement

What does ultra-low EMF mean in an infrared sauna, and how is it measured?

Answer

“Ultra-low EMF” in an infrared sauna refers to a design that keeps electromagnetic field exposure as low as reasonably achievable during use. EMF is a broad term that can include several types of fields produced by electrical power and electronics—most commonly extremely low frequency (ELF) magnetic fields from AC wiring and heaters, and electric fields from energized components.

Because there’s no single universal “ultra-low” definition across the entire sauna industry, the phrase usually signals that the manufacturer has engineered the heater system, wiring layout, shielding, and grounding to reduce readings at the user’s position (where your body actually sits) rather than only near the power entry point.

EMF is typically measured with handheld meters, and the exact number you see depends on what you’re measuring and how you measure it:

Magnetic fields are often reported in milligauss (mG) or microtesla (µT). A gauss meter or a tri-field meter can measure this.
Electric fields are commonly reported in volts per meter (V/m), measured with an electric-field meter or tri-field meter.

For meaningful comparisons, measurements should specify the distance from the source and the location inside the sauna—such as at the backrest, bench, or where your torso and legs will be. Readings can vary significantly between a measurement taken inches from a heater panel versus one taken at the seated position. Results can also change depending on whether the sauna is actively heating, whether lights or control panels are on, and how the meter is oriented.

FAQ

Is ultra-low EMF the same as zero EMF?

No. Any powered electrical product can generate some EMF, especially when current is flowing. “Ultra-low” generally means the sauna is engineered to reduce EMF levels to very low readings at user distance rather than eliminating EMF entirely.
