Infrared saunas, scored
Ranked by composite. The EMF column is the honest line: a low-EMF claim only counts when a named third party measured it where you actually sit. Almost no brand can show that, which is why so few clear the top bands.
Read the bands carefully
Most saunas here land in Limited. That is mostly a statement about evidence, not build quality: their low-EMF claim is not yet verified at the seat by a named third party, and EMF is our heaviest-weighted dimension. A Limited sauna can still be well built and pleasant to use - it just has not proven the one number its marketing leans on hardest. Read Limited here as claim unverified at the seat, not bad sauna.
We do reward documented testing: a brand that publishes a named lab report showing a low figure scores above one with a bare or unsourced claim, even when the measurement was taken at the heater rather than the seat. But that partial credit is capped - only an at-the-seat figure clears the top bands. See the methodology.
