Low EMF Infrared Saunas

What is a low EMF sauna?

A low EMF sauna is an infrared sauna described as giving off a low electromagnetic field (EMF). The description is worth as much as the maker's document behind it, so before EMF decides between two saunas, find that document for the exact model and check four things in it:

• An EMF figure with its unit. An EMF reading stated with its unit can be set against another sauna's reading; the words "low EMF" by themselves cannot.
• Where the EMF reading was taken. At the surface of one heater, or at the bench and backrest where you sit, and at what distance from the heater.
• What was switched on for the EMF test. One heater on a test bench, or the assembled cabin running as you would use it.
• Who took the EMF reading, and when. A named testing laboratory and a test date, or a reading the maker took itself.

When the makers of two low EMF infrared saunas give readings taken the same way, compare those readings; when they do not, decide between the two on heaters, size and price instead.

Low EMF infrared saunas compared: heaters and size

• For one person: set Finnmark's FD-1, rated by Finnmark for one, beside SunRay's Sedona, rated by SunRay for one to two.
• If only a 120 V supply is available: rule out the FD-3 (240 V in Finnmark's manual) and the FD-5 Trinity XL (its Harvia heater 240 V single-phase or 208 V three-phase as listed by Bathing Brands, Finnmark's distributor); for every model's supply, see indoor infrared saunas. Your licensed electrician sizes the breaker and wire from the sauna's manual, the Harvia heater's manual for a Trinity model, and your local code.
• If you want hot stones with the infrared: choose between the two Trinity models here, the FD-4 for two people and the FD-5 Trinity XL for three to four, as Finnmark rates them.
• For one kind of infrared heat over another: SunRay's cabins here use carbon far-infrared heaters, and Finnmark describes the FD-1, FD-2 and FD-3 as full spectrum; each heat type has its own collection, far infrared saunas and full spectrum infrared saunas.

Low EMF infrared sauna prices and delivery

Prices in the low EMF infrared sauna collection run from $2,698 (SunRay's Evansport) to $8,995 (Finnmark's FD-5 Trinity XL). Each sauna comes with the heaters listed in the table, and no heater package is chosen separately; the price of all 13 covers freight within the contiguous United States.

Topture is an authorized retailer of both makers in this collection, SunRay Saunas and Finnmark Designs, and if part of one of these saunas arrives broken, noting it on the Bill of Lading at delivery lets Topture's full-value freight protection replace it. The infrared saunas page walks through the rest of an order with Topture, from booking the delivery appointment to the payment options.

Next steps for a low EMF infrared sauna shortlist

Where a low EMF infrared sauna shortlist goes next depends on the question still open:

• Whether EMF should outweigh heat type, size or price: how much EMF should matter when choosing an infrared sauna weighs it against the rest of the decision.
• The EMF documentation behind a particular model: raise it with Topture's Lifetime Expert Support while you are still comparing models.
• Still choosing between infrared and a traditional sauna: answer the questions in the 60-second sauna finder to see which type fits.
