How It Compares Unlike basic far-infrared saunas that use only carbon panels, the FD-1 combines both short-wave Spectrum Plus™ and long-wave Carbon 360° heaters — delivering full-spectrum infrared coverage for deeper penetration, higher temperatures, and a more complete therapeutic experience. Compared to traditional saunas, it operates at lower temperatures (up to 170°F vs. 190–212°F) while delivering deeper tissue penetration through infrared wavelengths, making it more comfortable for longer sessions.
