Clearlight Premier vs Clearlight Sanctuary
The Sanctuary edges it in our scoring, and for buyers who specifically want real near-infrared from a separate emitter, which it has and the Premier does not. If you only want far-infrared, the Premier delivers that for less. Neither has EMF verified at the seat, so the decision is feature versus price.
These are two of the closest-scoring saunas we list, both from a brand that publishes Vitatech tests it commissioned of bare heater panels (peaks of 0.12 to 0.36 mG at 2 inches; no seated in-cabin reading published). The choice between them is not about EMF, where they share the same evidence, but about spectrum: the Premier is a far-infrared cabin, while the Sanctuary adds a dedicated full-spectrum heater for genuine near-infrared.

FAQ
- Do I need the Sanctuary's full-spectrum heater?
- Only if you specifically want near-infrared. The Premier's far-infrared is the band behind most sauna research; the Sanctuary's added full-spectrum element delivers genuine near-infrared from a real, separate emitter, which is what justifies its higher price.
