Lower More Effective Farinfrared
Therasauna ceramic Theramitters offer lower surface temperature and more effective natural infrared with a micron range between 7 and 14 microns which have been proven to have special regenerative effects on the body with an optimum absorption at the 9.4 micron frequency.  Therasauna emits the greatest amount of infrared in the 9.4 micron range.  Many other saunas wavelength is only 5 or 8.  The theramitters have a radiant efficiency of 96% - the highest efficiency available.

Therasauna leads the way for the most efficient ceramic heaters and the only sauna company to use clean non toxic aspen wood.   The Theramitter Heaters are patented and FDA Cleared and unique.  96% efficient and FULL Spectrum so you get the near, mid and farinfrared.   Efficient and all saunas are 120v and don't require 240v to operate like other full spectrum saunas do.

  • Therasauna is also the only sauna with the mps control unit so you can set the temperature of the heaters individually.  Heater control is great when you have multiple people using the sauna at the same time that may prefer a different temperature. 

  • Therasauna is made in the USA and saunas are made to order.   Many saunas use glue and some glues are labeled non toxic but they are not chemical free. Therasauna screws together their saunas and do not use any glue.

  • Therasauna, high-glass content, solid-ceramic TheraMitters are very different from the traditional ceramic heaters in the industry because they are unique, patented heating unit that is made of solid ceramic, and is distinct from tubular ceramic heaters that consist of wire and metal thinly coated with ceramic. Tubular ceramic heaters are similar to the process of coating metal jewelry with silver to give the impression of solid sterling silver, but after time the underlying metal starts to show after the silver plating wears off. TheraSauna is the only major manufacturer in the United States offering true solid ceramic TheraMitters, with no metal rods. TheraMitter are solid ceramic and still remain more efficient than carbon fiber and safer to use in a sauna. TheraMitters are 96% efficient and have a life-time warranty. 

Ceramic is made from natural earth elements. TheraMitter™ heaters have the highest glass content in the industry which provides uninhibited transmission and output of far infrared. Concave Ceramic TheraMitter™ heaters are able to spread infrared heat waves in a 180º pattern, effectively covering every square inch inside the sauna. Due to the quality of the reflector, all energy is given direction toward the user to improve the delivery of far infrared.

TheraSauna's proprietary, high-glass content, solid-ceramic TheraMitters™ are very different from the traditional ceramic heaters in the industry. A TheraMitter™ is a unique, patented heating unit that is made of solid ceramic, and is distinct from tubular ceramic heaters that consist of wire and metal thinly coated with ceramic. Tubular ceramic heaters are similar to the process of coating metal jewelry with silver to give the impression of solid sterling silver, but after time the underlying metal starts to show after the silver plating wears off. TheraSauna® is the only major manufacturer in the United States offering true solid ceramic TheraMitters™, with no metal rods. So when researching the various types of heaters, do not be confused by the general misrepresentation of ceramic heaters. TheraSauna® has the only high-glass content, solid ceramic TheraMitter™ in the industry.

 Many comparisons to ceramic heaters do not ackowledge the actual different ceramic types and only focus on the tubular ceramic heaters. They never compare carbon fiber heaters to our ceramic TheraMitters™ and instead, compare to tubular and rod heaters. However, the tubular ceramic and rod heater saunas are dimishing in popularity in favor of carbon fiber heaters. Yet, our solid-ceramic TheraMitters™ still remain more efficient than carbon fiber and safer to use in a sauna. TheraMitters™ are 96% efficient and have a life-time warranty. Carbon fiber heaters, by contrast, are only 55% efficient and made of plastic sheets with microscopic fibers held together with resins and epoxy glues. Carbon fiber heaters also diminish in efficiency over time, while our TheraMitters™ remain at ceramic’s emissivity level of .96 on a black body scale scale of 0-1. Since our emisivity levels are so efficient, it's no wonder our competitors never reference TheraSauna's® solid-ceramic TheraMitters™ .

The newest type of heater to emerge is a "carbon and ceramic" combination. In actuality, these are carbon fiber heaters with a small amount of ceramic powder blown into the plastic and carbon fiber compound before the adhesive epoxy glues are applied. This does not truly change the performance of the heater; it is still a carbon fiber heater that operates at a surface temperature of approximately 200°-230°F, and still grossly inefficient when compared to our proprietary ceramic TheraMitters™. These heaters are still unable to consistently reach the important 9.4 micron level of far-infrared energy and are very slow to heat the sauna to the desired temperature. Carbon fiber technology is also usually limited to reaching about 130°F cabinet temperature.

Ceramic has been proven to be the best material for producing larger amounts of far-infrared. It has the highest emissivity rate, and produces longer wavelengths. TheraSauna® delivers between 6 -14 micron of far-infrared light, and the surface temperature of the TheraMitters™ can be set to variable temperatures between approximately 126°F and 450°F while still always producing beneficial infrared. Carbon heaters, in contrast, can only operate at a lower surface temperature of about 230°F, and do not have the ability to vary the temperature. These saunas actually power down and stop producing infrared when the set temperature is reached, meaning that about 40% of the sauna session is not producing infrared for the user. TheraSauna® acheives constant infrared output with the help of its patented Stable Heat System™ which allows the sauna to continuously produce infrared during the entire sauna session.

The EMF (Electromagnetic Field) is extremely low in the Ceramic TheraMitter™ due to the fact that the wire changes direction several times over the face of the heater, thus reducing the output of EMF. The watt density of the TheraMitter™ is ideal; providing the user with the highest output of far infrared at the most beneficial micron range for the human body.       

 This “Patented Control System” automatically maintains a constant output of far infrared heat at the 9.4 micron level. Other saunas turn off after reaching their set convection air temperature, losing air temperature and creating an ineffective range of infrared. The TheraSauna® Stable Heat™ System does not turn off, but powers down and sends a trickle charge of electricity to maintain the surface temperature of the TheraMitter™ heaters, thus providing a continuous and effective 9.4 micron range of far infrared to the user. TheraMitter™ emits infrared in wavelengths of 6 to 14 microns, with the greatest output at 9.4 microns. These wavelengths are similar to those naturally emitted by the human body, so your body absorbs more beneficial far infrared in a shorter treatment time natural process rids your body of harmful toxins.  

  stableheat.jpg    stableheatsm.png  madinusa.jpg   4personstragihtbenchinside.jpg

TheraSaunas® far-infrared is produced during the entire sauna session.  When the sauna reaches temperature, the patented MPS Touch Control Screen® idles the TheraMitters™ down to surface temperature of under 230°F. The TheraMitters™ will return to 400°F and above when necessary, keeping a steady temperature and micron range. 

The far-infrared produced is still consistently reaching the optimal 9.4 micron range for human absorption due to the unique physical design of solid ceramic TheraMitters™, penetrating up to 2” below the skin. This creates an environment where the user receives more infrared in 20 minutes than they would during a 40 minute session in other brand saunas. 

Therasauna® produces zero cold spots when operating and does not vent plastics and carbon fibers  into the sauna cabinet, unlike our competitors. Carbon saunas only reach the one surface temperature of approximately 230°F and turn off after reaching their set convection air temperature, losing air temperature and creating an ineffective range of infrared. 

The TheraSauna® Stable Heat™ System does not turn off, but powers down and sends a trickle charge of electricty to maintain the surface temperature of the TheraMitters™, thus consistently reaching the 9.4 micron range of far infrared.

The best example of how TheraSauna's® Stable Heat™ System works in relation to our competitors is to imagine a light switch. If the light switch is flipped on, the light in the room will turn on. The moment the switch is turned off, the light goes out and the room is dark. Infrared is a form of light, just like the visible light in the example, but on a different spectrum that is invisible to the naked eye. TheraSauna's® Stable Heat™ System remains on during the entire sauna session, meaning infrared is produced the entire sauna session, just like turning on the light with the light switch and leaving it on the whole time you are in the room.

In a competitor's sauna, the infrared will be produced until the set temperature is reached. The moment the set temperature is reached, infrared immediately stops being produced, just like shutting off the light with the light switch. No more infrared is being produced, just like flipping the light switch to off turns off the light. So, it's much like sitting in a room with the lights on for 40 minutes, but you have to sit in the dark for half of the time. Our Stable Heat™ System prevents this from happening in TheraSauna®, giving the user a clear advantage in the amount of exposure to far infrared.

Micron Power Select™ allows you to vary the infrared output from each TheraMitter™ zone and control the infrared micron range during your sauna session. TheraMitters™ can be exclusively customized to a surface temperature between approximately 450°F down to an amazing 126°F. This is a extremely useful feature for multiple sauna users. For example, the person on the right can set their back TheraMitters™ on full power and their feet to half power while the person on the left can set their back TheraMitter™ to 80% power and their feet to 60% power. This highly innovative feature allows you to program your sauna to your personal comfort level. The MPS settings can be adjusted from 100% to 7% for each zone. On the MPS Touchview Control screen in "MPS SETUP," you can choose the level for each TheraMitter™. The levels can be set in any combination at 7%, 13%, 20%, 27%, 33%, 40%, 47%, 53%, 60%, 67%, 73%, 80%, 87%, 93%, or 100%

The SpectraWave™ function is an exclusive feature that allows the sauna to move through a specific infrared spectrum. The sauna’s onboard computer system has 8 different pre-selected power settings and it will scroll through a new setting every 2 minutes. This feature allows TheraSauna® to produce near, middle, and far infrared energy when this feature is utilized. You can use the SpectraWave™ mode by navigating to the "USE NOW" screen and selecting "WAVE" in the mode section. See below for some sample SpectraWave™ power settings:


7 Day Programmable Control
mpscontrol.jpgmpssetup.jpgmpspreheat.jpgmpsclock.jpg mps-audio.jpg


 The MPS Setup screen allows you to set a custom session based on your preferences. Turning down the percentage will reduce the power level of the Theramitter™. The MPS Setup screen allows you to control how hot your sauna session is and also allows you to vary the levels of infrared. When you save these settings, the system will use the settings the next time MPS Mode is selected in the "Use Now" screen.


The Audio screen offers 5 unique & relaxing music tracks that can be played during your sauna session.  Choose from Rolling Waves, Oceanside, Jungle Symphony, Bubbling Brook, Peaceful Forest, or a mix of these tracks for the perfect relaxing sound therapy for your sauna session.

Infrared energy heats objects (like your body and the inside wood of the sauna) directly and penetrates up to 2 inches below the surface. Cedar and redwood contain a natural insecticide within the wood called turpines. When these naturally occurring oils within the wood are heated, they gas off a substance called cedrine. Cedrine attacks the central nervous system of insects and kills them. It can also cause vomiting and convulsions in humans. TheraSauna® is made of Aspen, which is a clear wood grown at elevations where the trees do not produce an insecticide. Aspen is 99% non-toxic and non-allergenic.
