Why Jacuzzi® Saunas


As a leader and innovator in the infrared sauna industry for over 20 years, we have been manufacturing infrared saunas that are both luxurious and effective. While our cabins are exceptional quality, the therapeutic benefits of infrared heat are our main focus.

Over the last eight years, there has been a big debate as to whether Carbon heaters or Ceramic heaters are “better.” Carbon heaters produce high quality, long wave infrared heat. The problem is they do not produce a lot of infrared heat; in our testing carbon heaters appeared weak. On the other hand, Ceramic heaters are very powerful and emit a lot of infrared heat, but the wavelength tended to be shorter, thus less therapeutic.

Our R&D department has ended that debate by introducing the ONLY combination Carbon/Ceramic far infrared heater. Clearlight True Wave™ Far Infrared Heaters combine both Carbon and Ceramic to produce healing infrared heat that is unmatched. Our heaters are comprised of micro-thin carbon fibers (1/1000th the thickness of a human hair) combined with our patented micro fine ceramic compound for higher infrared output (emissivity). We manufacture all of our heaters, in our own factory, in a special process wherein the carbon/ceramic layers are alternated with layers of a woven substrate, which unite under high heat and pressure to make one combined heater. This innovative process produces a heater with tremendous output and high thermal emissivity. The heater is then tested under power for several hours and measured for the electrical draw, surface temperature, and emf output in twelve locations.

The carbon in our heaters allows the heater to produce long wave far infrared heat. This long wave infrared heat penetrates deeper into your body and the infrared heat is more readily absorbed. The ceramic in our heaters gives the heaters a very high infrared output when compared to traditional carbon heaters so we can concentrate the heat directly on your body. All Clearlight Sauna® models utilize our True Wave™ Far Infrared Heaters.
We also developed the first and only virtually no-EMF combination carbon/ceramic heaters. This patent pending process allows us to cancel out virtually all of the EMF (electromagnetic fields).

Using a laboratory grade EMF meter and measuring directly on top of our True Wave heaters, our heaters have an average EMF output of about 2.5 milligauss (mg). Compare that to over 100mg for most of our competitors’ carbon based heaters. In addition, when we test where you’re actually sitting in the sauna, there is virtually no EMF.

"I’ve had the Clearlight sauna in operation for 2 weeks now and my wife and I are loving it. It has helped her rheumatoid arthritis and osteoarthritis pain immensely – she’s in it every day. The biggest thing I’ve noticed is the improvement in the quality of my sleep. I go to sleep more readily when I retire, sleep sounder, and don’t get up in the night as often as I did pre-sauna. I was out of town this week for 3 nights and really could tell a difference in sleep quality since I did not have it available"

Why are True Wave Far Infrared Heaters Better for you?

The larger size of our True Wave™ Far Infrared heaters means more surface area, resulting in lower surface temperature. The result of this low temperature: our heaters produce more FAR or LONG wave infrared heat which is more therapeutic for your body. This means better performance within the optimal wavelength range of 6 to 12 microns, with a large portion of wavelengths at 9.4 microns. The human body absorbs more infrared at 9.4 microns.

With the high far infrared output (emissivity) of our heaters, you not only get the highest quality infrared heat, but you get a lot of it, right where you want it – your body core. We position our heaters so that they surround your body, concentrating the heat on your body core.

The key to infrared therapy is heating your body directly. You want heat on the front of your body and on the back of your body. Every Clearlight Sauna® model has heaters on the front wall, back wall, side walls, underneath the bench, next to your calves and in the floor. Surround Yourself In Wellness™ with Jacuzzi® infrared saunas.

Clearlight Jacuzzi® Saunas Core Body Temperature and Heart Rate Study

All Clearlight Infrared Sauna® models have been shown to raise core body temperature. The data above from the Arcadia Cancer Clinic in Germany shows an average of a 3% core body temperature increase in a 40-minute Clearlight Infrared Sauna session.
All Clearlight Infrared Sauna® models have also been shown to increase your heart rate during a sauna session. The data above from the Arcadia Cancer Clinic in Germany shows an average of a 68% increase in heart rate in a 40-minute Clearlight Infrared Sauna session.

What to Look for when Choosing a Far Infrared Heater

We understand the difficulty in choosing an infrared sauna and trying to determine which heaters will work best for you. The following are a few questions to ask when comparing various heaters:
heater placementheater-comparison-hm3
1) What is the surface temperature of the heater?
This is one of the most important questions because it determines both the size the of the infrared wavelength, as well as the overall effectiveness of the heater. The two scientific principles that govern infrared emissions are called Planks Law and Weins Law. Both of these scientific laws have an equation with several constants and the only variable is the surface temperature of the heater. They both say that the lower the surface temperature of the heater, the longer the infrared wave will be, and thus the more effective the infrared heat will be for you.

2) Does the sauna have front and back heaters?
One of the keys to sweating and effective detoxification in an infrared sauna is to warm your body and raise your core body temperature. You want a sauna that heats both the back and front of your body. You cannot effectively detox in an infrared sauna without warming your front core. Many saunas on the market today don’t include front heaters or they have very small front heaters for aesthetic reasons – a huge mistake in our opinion. Our Clearlight True Wave™ heaters are positioned so that they cover your full back area as well as your front core. They do an excellent job of warming your body core and thus raising your core body temperature.

3) Is the far infrared heat directed where it’s most needed?
We’ve found that the problem with traditional carbon heaters is that, while they produce high quality infrared heat, they don’t produce a lot of it and it’s not concentrated on your body. These heaters work well when they are within a few inches of your body, as in some of the lay down infrared units, but not when they are in a large sauna cabin. And when these heaters go all the way up over your head, they are really just heating the sauna cabin air. Because infrared heat travels in a straight line, you want to make sure that the heaters are directing the heat toward your body core, not just into the air around you.

4) Radiant heat vs. reflected heat:
You will see many heaters on the market that are a thin, single rod with a metal reflector behind it. Generally, these heaters produce low quality far infrared heat when compared to a large flat panel far infrared heater. First, a single rod heater must run at a much higher surface temperature than a large flat radiant heater to produce sufficient infrared heat. As mentioned above, the higher the surface temperature, the less effective the infrared heat will be.

Gentle Heat that Penetrates Deep!

Because of the lower surface temperature of our True Wave™ Far Infrared Heaters, sitting in your Clearlight sauna is more enjoyable. You’ll find the heat in your Clearlight Sauna® model gentler than most, yet deeper and more penetrating – which is simply, overall, a better sauna experience.

In their book Beyond Antibiotics, Drs. Michael A. Schmidt et al. state the following:

“Saunas are being used by some doctors to stimulate the release of toxins from the bodies of their patients. They have found that a lower temperature (105-125℉ ) sauna taken for a longer duration is most beneficial. These low temperatures stimulate a fat sweat, which eliminates toxins stored in fat, as opposed to the high temperature sauna, which encourages a water sweat.”

Clearlight Jacuzzi® Saunas Use Tuned Far Infrared

The human body sends and receives far infrared waves. The range of far infrared waves generated by the human body is 6 to 20 microns. The optimal micron output range of an infrared heater is between 6 and 12 microns, which is very close to the resonant frequency of a water molecule and the optimum infrared absorption rate of the human body. This similarity makes sense since our bodies are almost 70% water. This range, sometimes called the “Vital Rays,” appears to have special regenerative effects on the body.

When far infrared waves are applied to water molecules, these molecules begin to vibrate. This vibration reduces the ion bonds and the eventual breakdown of the water molecules causes encapsulated gasses and other toxic materials to be released.

The Clearlight True Wave™ patent pending heater design allows for better performance well within this vital wave range of 6 to 12 microns, with a good portion of wavelengths at the frequency at which a water molecule resonates or vibrates. This vibration causes a release of cellular toxins such as mercury, aluminum, cholesterol, and toxic gasses such as sulfur and formaldehyde. This optimal micron output also allows for deeper penetration of far infrared heat, which improves pain relief, detoxification, circulation, and increased peripheral blood flow.

Our Carbon/Ceramic Combination Far Infrared Heaters Compared to Other Heaters

Don’t be fooled by marketing hype and supposed studies stating that only one material is better for producing far infrared heat – know the facts. When evaluating a material for it’s properties to give off far infrared heat, we evaluate its “emissivity.” Emissivity is the measure of an object’s ability to emit far infrared energy. Emissivity can have a value from 0 (shiny mirror) to 1.0 (blackbody).

Raytek, one of the leading infrared instrument manufacturers, has the following emissivity tables on their website. When reading the table, please note the values in 5-14 micron ranges – the “vital” range for healing the human body (the symbol μm stands for “micron”). You will see that ceramic has an emissivity of .95 – the closest to a perfect black body at 1.0. That is why the patented ceramic compound that we add to our True Wave™ heaters is so important.

Please note the highlighted entries in the table:

Emissivity Table for Non-Metals (Ceramic vs. Carbon)

Table for Metals (Ceramic vs. Steel and Incoloy Rods)

Most infrared heaters used in our competitors’ saunas were designed for industrial use. These infrared heaters are most either used to cure the paint on cars because it heats the paint from the inside out, or as room heaters. Clearlight Infrared True Wave™ heaters were designed by us, specifically for use in our saunas, to heat the human body.

Clearlight True Wave Full Spectrum Infrared Heaters

All Clearlight Sanctuary Sauna™ models include our True Wave™ Full Spectrum infrared heaters. These heaters are high output infrared heaters producing near, mid and far infrared. Every Clearlight Sanctuary Sauna™ model has 1,000 watts of full spectrum infrared. That’s 25 times the power of our closest competitor.

What is Full Spectrum Infrared?

The infrared spectrum is comprised of near, mid and far infrared. While the majority of the benefit you receive in your Jacuzzi® sauna comes from the far infrared band, there are added benefits and enhancements by adding in all three wavelengths.

Our Clearlight True Wave™ Full Spectrum heaters emit about 1/3 near infrared, 1/3 mid infrared and 1/3 far infrared. The following are some of the benefits of full spectrum infrared therapy:

• Near Infrared is the shortest wavelength, and will be absorbed just below the surface of the skin creating a sweat that promotes healing and revitalization.

• Mid infrared is a longer wavelength that can penetrate deeper into the body’s soft tissue increasing circulation, releasing oxygen to reach injured areas.

• Far infrared is the longest wavelength, which penetrates the fat cells causing vasodilation, where the fat cells vibrate to expel toxins, resulting in the greatest levels of detoxification, while also stimulating your metabolism to aid in weight-loss.

Clearlight Jacuzzi® Infrared Saunas are Low EMF and ELF

As a premier wellness company, your health and safety are our number one focus. Our True Wave™ far infrared and full spectrum infrared heaters are the most effective and safest infrared heaters available. Clearlight Infrared Sauna® models are the only ONLY infrared sauna that cancels out both EMF and ELF. Electromagnetic Fields (EMF) are energy waves with frequencies below 300 hertz or cycles per second. Extremely low frequency (ELF) are the electric fields with frequencies from 3 to 30 hertz.

All Clearlight Infrared Sauna® models offer the lowest and safest EMF and ELF levels of any infrared sauna on the market, bar-none. The EMF levels in your Clearlight Premier™ and Clearlight Sanctuary™ saunas will be mostly below 1mg when tested directly on the heater itself. When tested for where you are actually sitting in the sauna, the EMF levels are virtually 0mg. The ELF levels in your Clearlight Infrared Sauna™ are 3 – 5 times below the threshold of concern. All of our competitors are over 20 times above the threshold of concern.

Be sure to ask when shopping for an infrared sauna if their infrared saunas are both low EMF and low ELF.

I have always known of the benefits of saunas and regularly would use the one in my gym. I was elated when my friend referred me to your company making it possible to have and use an infrared sauna in the privacy of my own home.

I use my sauna every day the first thing each morning and can see how my body is detoxifying as a result. My aches and pains have decreased considerably and my skin has a beautiful glow. After each use, I have an immense feeling of wellness and vigor that takes me through the day. Having my infrared sauna in my home is no less than having heaven on earth.

Low EMF (Electromagnetic Field)

As the pioneer of low EMF carbon infrared sauna heaters, our patent-pending infrared heater technology reduces the EMF levels where you sit in the sauna to virtually zero. Our exclusive manufacturing process allows us to cancel out EMF to levels that are virtually undetectable.

Using ultra-sensitive EMF testing equipment, all of our heaters are tested to ensure safe levels of EMF. Electromagnetic Fields are measured in milligauss (mG). It is generally accepted that exposure to EMF should not exceed 3 milligauss. The EPA (U.S. Environmental Protection Agency) has proposed a safety standard of 3 mG. Sweden has also set a recommended safety limit of 3 mG. When EMF levels are measured inside your Jacuzzi® sauna, all around your seated position, EMF levels are virtually undetectable.

Please see the testing below performed by EMF testing lab VitaTech Electromagnetics. These EMF readings are measured directly on the heater. Remember, where you are seated in the sauna, the levels are virtually zero.

Low ELF (Extremely Low Frequency)

Extremely low frequency (ELF) radiation is at the low-energy end of the electromagnetic spectrum and is often referred to as the Electric Fields. The most common ELF field is radiated by utility power lines. You are exposed to these fields whenever you are near electrical appliances of any kind.

The effect of the electric field strength on a person’s body is defined as body voltage strength and is expressed in millivolts (mV). Out in nature, far away from electrical sources, the human body’s natural body voltage is near 0mV. It has been found that when this body voltage rises, in sensitive individuals, it can cause disturbed sleep, irritating sensations and other ailments.

The Threshold of Concern level for ELF is 1,000 mV. When testing Clearlight Saunas, with our low ELF technology, users test as low as 200 mV – five times below the threshold of concern. When testing our competitors’ saunas, their ELF levels exceed 20,000 mV – twenty times above the threshold of concern.

Each individual’s levels will vary, as some people are more conductive due to the makeup of their body (higher salt levels, for example). In our testing, we did not have anyone test above the threshold of concern in a shielded Clearlight Infrared Sauna®.

Shielded Metal Conduit Wiring

Shielded Metal Conduit Wiring
Clearlight Jacuzzi® saunas are one of the only infrared saunas with the electrical wiring run through metal conduit. This shields both the ELF and EMF to ensure that your sauna is the safest available. In addition to running the wiring through metal conduit, we also twist the wires, as this further reduces ELF and EMF levels. Another Jacuzzi® infrared sauna exclusive!
When directly testing our sauna heaters, as opposed to the individual user, our ELF levels are equally impressive. The Threshold Of Concern when testing the sauna itself is 10 Volts/Meter (V/m). Clearlight Infrared Saunas® average 3.4 V/m. Our competitors measure 300+ V/m.

Clearlight Jacuzzi® Saunas are the ONLY Infrared Sauna with virtually no EMF and no ELF!

See the full test report here (2.47 MB PDF)
Ask any of our competitors what levels of EMF and ELF their sauna heaters emit. You will be shocked at how high the levels are or the fact that they may not even know! The following are some examples of tests in our competitors saunas:
Infrared Heater EMF Comparison
*acceptable levels should be below 3mG.

What are EMF/ELF?

Electromagnetic Fields (EMF) are energy waves with frequencies below 300 hertz or cycles per second. The electromagnetic fields we encounter daily come from every day things such as power lines, radar and microwave towers, television and computer screens, motors, fluorescent lights, microwave ovens, cell phones, electric blankets, house wiring and hundreds of other common electrical devices.

Levels of electromagnetic fields (EMF) from human-made sources have increased steadily over the past 50-100 years. Most EMF exposures come from increased use of electricity and new technologies. In the past decades, potential adverse effects from EMF exposure on human health have been an important topic of research. In fact, in California, the California Public Utilities Commission (CPUC) created the California Electric and Magnetic Fields Program to research and provide education and technical assistance on the possible health effects of exposure to EMF.

In the California EMF report published in 2002, the researchers concluded, among other things, that “To one degree or another, all three of the DHS scientists are inclined to believe that EMFs can cause some degree of increased risk of childhood leukemia, adult brain cancer, Lou Gehrig’s Disease, and miscarriage.” and indicated that levels below 3 mG are safe.

Are EMF & ELF harmful to the human body?

Numerous studies have produced contradictory results, yet some experts are convinced that the threat is real.

Dr. David Carpenter, Dean at the School of Public Health, State University of New York, believes it is likely that up to 30% of all childhood cancers come from exposure to EMFs. The Environmental Protection Agency (EPA) warns “There is reason for concern” and advises prudent avoidance.”

Martin Halper, the EPA’s Director of Analysis and Support says “I have never seen a set of epidemiological studies that remotely approached the weight of evidence that we’re seeing with EMFs. Clearly, there is something here.”

Concern over EMFs exploded after Paul Brodeur wrote a series of articles in The New Yorker Magazine in June 1989. Because of Paul Brodeur’s reputation, his articles had a catalytic effect on scientists, reporters and concerned people throughout the world.

In November 1989, the Department of Energy reported that “It has now become generally accepted that there are, indeed, biological effects due to field exposure.”

The EMF issue gained more publicity in 1990 when alarming reports appeared in Time, The Wall Street Journal, Business Week and popular computer publications. Both ABC’s Ted Koppel and CBS’s Dan Rather also aired special segments on EMFs.

Some health effects linked with EMF are:

  • Memory Loss
  • Depression
  • Loss of Energy
  • Irritability
  • Inability To Concentrate
  • Weakened Immune System
  • Chronic Fatigue
  • Headaches
The following are links to more information about the effects of EMF / ELF and Clips from a variety of sources:
Excerpt from Peter Asmus book “Introduction to Energy in California” (University of California Press, 2009):

“Remember when people who spoke of cigarettes causing cancer were derided as being alarmist nuts? (If you do remember that, you are at least 55 years old!) Today people who assert that there could be, let alone that there is, a risk associated with cell phone use are viewed as a bit wacky. Well, the Marlboro man died of lung cancer and it appears there is a growing body of information to suggest that the Nokia man might be saddled with dementia or Alzheimers (among others) for the privilege!

Consider the following findings:
• 3% of the population may have severe reactions to electromagnetic fields (EMFs) thought by some to shorten life expectancy.
• Young people who start using cell phones before the age of 20 have a fivefold increase in brain cancer risk.
• Up to one-third of the population may suffer from electrical hypersensitivity from EMF exposure.

Wood Care in your Infrared Sauna

Clearlight Jacuzzi® saunas are made from the highest quality woods. All structures using wood are susceptible to minor dents, scratches and scuffing. This is normal and will not affect the integrity or operation of your sauna.

Wood is a living material that continues to respond to climate conditions, even after being manufactured into a sauna. Variations in the color or grain, and irregularities such as fine cracks, are part of the natural beauty of the wood and in no way should be considered defects. During normal operation, wood may crack slightly due to the changes in moisture level. This will not affect the structural integrity of the sauna.

Prior to shipping, the wood is inspected for consistency, color and quality. Our saunas are shipped around the globe and can experience slight blemishes, scratches or scuffs in transit. In most cases, these blemishes on the exterior of the sauna can be concealed by using a small amount of furniture polish, oil or other furniture treatment. The interior blemishes, scratches, or scuffs can be either left alone or sanded. Please avoid any treatment containing benzene or a high concentration of alcohol.


Assembly of your Clearlight Infrared Sauna is quick and easy. It usually takes two people about 2-3 hours to assemble the sauna, depending on the model. No tools are required for the overall assembly, except a screwdriver for the door handle, and the included allen wrench to connect the glass in our Clearlight Sanctuary saunas. Your infrared sauna is pre-wired and made with precision craftsmanship, so it connects together with ease.

We build your infrared sauna in our factory, and every sauna is built and tested to ensure it meets our strict quality control standards. We then disassemble it, box it up and ship it to you. This way we ensure you will receive your sauna in perfect condition. If you need help while setting up your sauna, simply call us at 800 674 8896. We are happy to be of service!

All Clearlight Sauna® models are not just made with high quality and craftsmanship, but with the knowledge and experience brought by Dr. Raleigh Duncan. With many years of experience as a Doctor of Chiropractic and research into infrared therapy, Dr. Duncan’s knowledge and expertise can be felt in every model.

“Many years ago, I received a call from a man very worried about his wife. She had been diagnosed with severe fibromyalgia, an extremely debilitating disease. She was racked with pain throughout her body most of the time and could only walk with great effort. She hardly slept at night and said that she could feel pain in every hair follicle on her head. Once a robust women, she loved her work in the publishing industry as well as gardening and cooking. Now she could only work a few hours per week by phone from a chair in her house.
They had tried the rounds of doctors and practitioners, without much help, and were exhausted physically, emotionally and financially. He felt that the type of deep heat our infrared saunas provided might just do the trick and help the women that he dearly loved.

At the time we were not sure if we could help as we had no direct experience with fibromyalgia. We had a quick conference to decide what course to take. To do nothing would be unthinkable, but we couldn’t offer false hope in order to get a sale either. We were clear that we were in the business to help people, not take advantage of them. We offered to let them use a new sauna for two months that we would deliver and set up at no charge. We made it clear that they were under no obligation whatsoever at anytime, we just hoped it would help and if not, we would pick up the far infrared sauna.

After just two weeks he called back, overjoyed. His wife was sleeping better now, sometimes through the whole night. She had much less pain and her spirits had also improved. She now had hope! They bought the sauna; she went into almost total remission except for a few flare-ups now and then. The sauna was her sanctuary of health. She was able to return to work and hobbies full time.
