Are all FIR saunas the same?
All FAR INFRARED RAY SAUNAS are not created equal!!
The very heart of the FIR Sauna is its Heating Elements. The majority of FIR saunas are fitted with Ceramic Heating Elements also known as ‘Ceramic Semi Conductors’ depending on the manufacturer.
Ceramic type / ceramic semi conductor elements can use up to 70% of the available oxygen inside the cabin or enclosure and breathing the oxygen-depleted air may lead to considerable discomfort for the users. Promoters of personal type sauna using the ceramic semi conductor elements would like you to believe that because the user’s head is outside the cabin you do not breathe the oxygen depleted air, but researchers have stated that the lack of oxygen taken through the skin is still felt significantly, especially as heat causes skin pores to open.
Fortunately new technology deals with this problem. There are patented, ultra-thin, super-conductive FIR emitting heating elements used in the design of space age technology FIR saunas. These elements use just 5% of available oxygen inside the cabin and the user can relax and enjoy the many benefit attached to the use of a FIR Sauna. The new portable personal FIR sauna ED2000 MK2 uses patented, ultra-thin, super-conductive FIR emitting heating elements and is designed to keep the user’s the enclosure, thus the user is much more comfortable. 12 months warranty.

Disclaimer/Contraindications
As may be noted the segment of the infrared spectrum emitted by the Infrared Thermal System is reputed to offer an astounding range of possible therapeutic benefits and effects in research conducted around the world. The data presented is offered for reference purposes only and to stimulate further observation. Infrared Thermal Systems creating a cure for, or treating of, any disease is neither implied nor should be inferred.
If you are suffering from a disease be certain to consult with a primary-care physician concerning it.
If you are using any prescription drugs check with your physician or pharmacist for any possible change in the drug's effect likely to result from any interaction with infrared energy.
If you have a recent (acute) joint injury, it should not be heated for the first 48 hours after an injury or until the hot and swollen symptoms subside. If you have a joint or joints that are chronically hot and swollen, these joints may respond poorly to vigorous heating of any kind. Vigorous heating is strictly contraindicated in cases of enclosed infections, be they dental, in joints, or in any other tissues.
