All Clearlight® Saunas are optimised for low EMF. This specifically refers to EMF, meaning electromagnetic frequencies. ELF (extremely low frequencies) is another type of “EMF”, is more complex, and not so easy to mitigate.
According to our website, the Threshold of Concern level for ELF is 1,000 mV. Our wooden cabin saunas have a lower ELF in comparison to the Dome sauna because of the thickness of the cabin walls. The Dome sauna has a thinner wall due to the design and will have a higher ELF reading than our cabin saunas - still much lower than the Threshold of Concern.
Please see the below video explaining the above in further detail;
