In the infrared saunas we sell, the EMF tiers mean this: Low EMF panels measure 5 to 10 milligauss (mG), Ultra Low EMF panels measure 3 to 5 mG, and Near Zero EMF panels measure under 3 mG, all taken 2 to 3 inches from the heating panel. Full Spectrum is not an EMF tier at all; it describes a heater mix of near, mid and far infrared, and most Full Spectrum cabins in our range use Near Zero EMF carbon panels. Those are the manufacturer figures for Maxxus, Dynamic and Golden Designs, and they are printed in the spec table on each product page.
EMF tier is one of the three infrared decisions (with heat type and capacity) covered in our Home Sauna Buying Guide. Here is what the numbers actually mean, what they do not mean, and how much each step up costs.
What is EMF in an infrared sauna?
EMF stands for electromagnetic field. Anything carrying electric current produces one, and the magnetic component is measured in milligauss (mG). Field strength falls off quickly with distance, so the number only means something with a stated measurement distance attached. That is why the sauna figures above are all quoted at 2 to 3 inches from the panel: it is the industry convention for a worst-case reading, close to the source.
Saunas get more attention on EMF than, say, a toaster because of the exposure pattern. You sit within a foot or two of the panels for 30 to 45 minutes, several times a week, and your back may rest against one. Panel design (shielded wiring, how the carbon element is laid out, where the leads run) is what separates the tiers.
Sauna EMF tiers in real numbers
| Tier | Published reading (2 to 3 in. from panel) | Where you find it |
|---|---|---|
| Low EMF | 5 to 10 mG | Entry tier on Maxxus Low EMF and most non-Elite Dynamic cabins |
| Ultra Low EMF | 3 to 5 mG | Maxxus S-Line Ultra Low and Dynamic "Elite" models |
| Near Zero EMF | Under 3 mG (one Maxxus Bellevue model is rated under 2 mG) | Maxxus Near Zero, every Golden Designs infrared cabin, most Dynamic Full Spectrum models |
| Full Spectrum | Not an EMF rating; near, mid and far infrared heaters together | Maxxus Full Spectrum, Dynamic FS models, Golden Designs Reserve Edition and hybrids (far infrared panels usually Near Zero rated) |
Two things worth noticing. The tiers overlap at the boundaries (5 mG sits at the top of Ultra Low and the bottom of Low), so a "Low" and an "Ultra Low" cabin from the same brand may be closer than the names suggest. And the gap between Low and Near Zero is a factor of roughly two to three at the panel surface, which shrinks further at seating distance. It is a real engineering difference, not a marketing one, but it is a difference of degree.
What the tier names do not tell you
There is no government standard, in the US or elsewhere, that defines "Low", "Ultra Low" or "Near Zero" EMF for saunas. The figures are set and tested by each manufacturer. That is why we list the exact milligauss reading and the measurement distance in the spec table on every sauna page, so you never have to ask. A "Low EMF" label with no number attached is not comparable to anything, and we will confirm the figure in writing before you order if you want it on record.
Also note that the rating applies to the far infrared carbon panels. On Full Spectrum cabins, the near infrared elements and, on hybrids, the stove are typically not rated separately.
Is sauna EMF something to worry about?
Major health bodies, including the World Health Organization, have not established that everyday low-level magnetic field exposure causes health problems, and they describe the evidence as limited rather than settled. What most guidance does say is that reducing unnecessary close-range, repeated exposure is a reasonable precaution. Regular sauna use fits that description, which is the honest case for paying attention to the tier without treating it as a medical decision. If EMF is a specific concern for you, or you are buying for a household with young children, choosing Ultra Low or Near Zero is a modest cost for a lower reading.
How much does a lower EMF tier cost?
Less than most people expect, because the cabins are otherwise identical. Live examples from our catalog on the day of writing:
| Cabin | Low EMF | Ultra Low EMF | Near Zero EMF |
|---|---|---|---|
| Dynamic Avila 1 to 2 person | $1,899 | $2,099 | n/a |
| Maxxus Seattle 2 person | $2,299 | n/a | $2,699 |
| Maxxus S-Line 2 person | $2,899 | $3,299 | n/a |
| Dynamic Bergamo 4 person | $3,299 | $3,999 | n/a |
| Maxxus 4 person hemlock | $3,699 | n/a | $4,499 |
So the step from Low to Ultra Low runs about $200 to $700, and Low to Near Zero about $400 to $800, depending on cabin size. Golden Designs skips the question entirely: every infrared cabin they make, from the $3,999 1 person Reserve Edition to the $9,999 8 person Full Spectrum, is Near Zero rated.
Which EMF tier should you choose?
- Low EMF is fine for most buyers, particularly if you sauna a few times a week and are choosing on price or capacity first. 5 to 10 mG at the panel is already a shielded design.
- Ultra Low EMF is the sensible middle if you will use the cabin daily and the $200 to $700 premium is easy to absorb.
- Near Zero EMF is worth it if EMF is the reason you are reading this article, if children will use the cabin, or if you are already looking at Golden Designs or a Full Spectrum model, where it comes standard.
Do not let the EMF tier override the two decisions that change your daily experience more: cabin size and whether you want far infrared only or Full Spectrum. Our Sauna Comparison Chart lines up every brand by tier and capacity in one table.
Frequently asked questions
What is a low EMF infrared sauna?
A low EMF infrared sauna uses heating panels rated at 5 to 10 milligauss measured 2 to 3 inches from the panel, which is the entry shielding tier on Maxxus and Dynamic cabins. Ultra Low EMF panels measure 3 to 5 mG and Near Zero EMF panels under 3 mG at the same distance.
What does Near Zero EMF mean on a sauna?
Near Zero EMF means the far infrared panels measure under 3 milligauss at 2 to 3 inches, the lowest published tier from Maxxus, Dynamic and Golden Designs. It does not mean zero, and it does not cover near infrared elements or a hybrid's stove, which are usually not rated separately.
Is Full Spectrum the same as Near Zero EMF?
No. Full Spectrum describes a heater mix of near, mid and far infrared in one cabin, not an EMF level. Most Full Spectrum cabins we carry do use Near Zero rated far infrared panels, and the EMF line in the spec table on each product page confirms it.
Does a lower EMF sauna cost a lot more?
Usually $200 to $800 more for the same cabin. For example, the Maxxus Seattle 2 person is $2,299 in Low EMF and $2,699 in Near Zero EMF, and the Dynamic Avila is $1,899 in Low EMF and $2,099 in Ultra Low EMF, prices as of the day of writing.
