Questions and Answers

The challenge for the consumer today is that unless you can see it in person, you cannot tell the difference between a quality infrared sauna and a cheap knock-off as the pictures on the internet can look basically the same. The questions below are some of the more common questions we receive and will help you make an informed decision so you can purchase a high quality, therapeutic infrared sauna.

Why do so many saunas look the same from website to website?
Because they are. Many companies are importing containers of the same saunas or saunas with only slight variations. Look at the keypad to tell which are from the same factory; it’s somewhat amusing. We’re flattered that they’ve decided to knock-off the look that we pioneered many years ago.
How does a Clearlight® sauna differ?
Quality of design and construction coupled with superior and innovative heating technology. We start with the highest quality woods. All saunas are built by hand to our strict 48 point Quality Control. No sauna leaves the factory without being fully tested and approved by two levels of quality control. With the ETL and CE certification, we are bound to provide a high quality product.  We use no toxic glues.  Our saunas are hand sanded, the handles and trim are hand crafted, the tongue and groove wood is color matched to look beautiful and all Clearlight Infrared Sauna models are designed to give you a lifetime of health and relaxation benefits. Almost every other infrared sauna company uses industrial heaters that have been adapted to be used in an infrared sauna.  Not willing to settle with industrial infrared heaters, we manufacture our own patented-pending infrared sauna heaters in our factory.  We manufacture our True Wave combination Carbon/Ceramic far infrared heaters and full spectrum (near,mid,far) infrared heaters.

  • Being innovators in the infrared sauna industry, we have always set the trends that have guided the industry: Our True Wave™ far infrared heaters are the only infrared heaters on the market that combine both the high output of ceramic with the long wavelength of carbon to produce a sauna session that is unmatched. Our True Wave™ full spectrum infrared heaters deliver more near infrared, mid infrared and far infrared than any other infrared sauna on the market.  These heaters are designed specifically to heat the human body.
  • We are the industry pioneer of low EMF carbon based infrared heaters and offer the only low EMF full spectrum infrared sauna on the market.
  • We are the first company to offer a low ELF infrared sauna. All Clearlight Premier™ Far Infrared and Clearlight Sanctuary™ Full Spectrum sauna models include our ELF canceling technology.
How are our Clearlight Sauna® models different from other infrared saunas?
Our Clearlight Sauna® models are the only infrared saunas designed by a doctor. Dr. Raleigh Duncan has dedicated the last 20+ years to researching and developing technology to help heal the human body and he has been researching infrared therapy and its benefits for even longer. Our years of manufacturing infrared saunas go into every Clearlight Sauna® model While our sauna cabins are exceptional quality, with hand sanded panels, high quality close grain wood and attention to detail, the therapeutic benefits are our main focus. Our R&D department is always researching and testing new components for your sauna so when you buy one of our infrared saunas, you are buying the highest quality, most therapeutic infrared sauna available. With our limited lifetime warranty for home use, we stand behind our saunas. This warranty covers the entire sauna; the wood cabin, heaters, controls and even the audio system. We will be here next year and five years from now should you need replacement parts or have any questions about the proper use or your sauna. We believe that by committing to a lifetime warranty for our customers, it ensures that we build a high quality infrared sauna that will last. This informs every manufacturing decision we make as we know we will have to support your sauna for many years to come.
What type of infrared heater is best?
Far Infrared Heaters When comparing far infrared sauna heaters you need to look at the size of the heater, the material that is producing the infrared heat, the quality of the heat and the surface temperature of the heater. The two most common materials used in far infrared heaters are ceramic and carbon. Ceramic is a very efficient, effective material when heated to produce infrared heat. Ceramic has a very high emissivity rating, meaning it produces a lot of infrared heat. The drawback to ceramic heaters is that they tend to produce a shorter infrared wavelength. Shorter infrared wavelengths are not as readily absorbed by the human body so they are less therapeutic. Generally speaking, Carbon infrared heaters produce a longer infrared wavelength. Carbon is very light so the heaters can be bigger and can run at a lower surface temperature. These low surface temperatures produce long wave infrared heat. Long wave far infrared heat is readily absorbed by the human body and will produce more desirable therapeutic results. The drawback of carbon heaters is that, while they produce high quality infrared heat, they do not produce a lot of infrared – they are weak. In technical terms, they have a lower emissivity rating as compared to ceramic heaters. Most companies that use carbon heaters extend their heaters well up into the head region and almost to the ceiling in the sauna in an effort to try and get more heat into the sauna. They do this because of the low output of their heaters.  This is wasted infrared heat as it is only heating the air over your head and not your body directly. We also believe heating the head directly is not recommended in infrared therapy. Our True Wave™ far infrared heaters are the only infrared heaters that combine both carbon and ceramic into one heater for a truly exceptional infrared sauna experience. They are built by us and designed to heat the human body. True Wave™ Infrared Heaters produce the long wave infrared heat of a carbon heaters with the very high infrared output of a ceramic heater combined into one heater. It really is the best of both worlds and they are fantastic infrared heaters. Within seconds of sitting in any Clearlight Sauna­® model, you can feel the difference in the quality of the infrared heat. You will not find this heating technology anywhere else. It is exclusive to Jacuzzi® infrared saunas models. Full Spectrum Infrared Heaters A full spectrum infrared heater emits all three infrared wavelengths: near (IR-A), mid (IR-B) and far infrared (IR-C). Some infrared saunas offer a combination of heaters to produce full spectrum infrared heat. The sauna may have one heater that produces far infrared, one that produces mid infrared and one that produces near infrared. You will also see some infrared saunas that use low wattage (10-40 watt) LED’s to produce near infrared. Our belief is that LED near infrared light therapy is very effective for topical infrared treatments however, it is not suited for the sauna environment. You want to put the LED’s directly on your skin. The DPL Nuve by LED Technologies is a great example of an effective FDA approved near infrared handheld device. With LED near infrared embedded in the wall of the sauna, you would have to climb up on the bench to receive effective therapy as the LED’s should be right up against the area you are treating. Clearlight Sanctuary Saunas utilize a halogen full spectrum heater. We have the halogen bulbs built to our specific wavelengths and standards. Our True Wave™ full spectrum infrared heaters emit about 1/3 near infrared, 1./3 mid infrared and 1/3 far infrared and each heater is a full 500 watts of full spectrum infrared heat. By offering all three wavelengths the infrared heat will penetrate deeper past the Epidermis and Dermis into the Subcutaneous layer offering maximum effectiveness.
Why are low EMF and low ELF levels important?
Low EMF Infrared Saunas Our True Wave™ far infrared heaters are the original carbon based infrared heaters with virtually no EMF (Electromagnetic Fields).  We pioneered this technology for use in infrared saunas. More and more research is being conducted into the harmful effects of EMF. That is why our R&D department spent over two years developing both patented and patent pending methods to eliminate virtually all of the EMF from our heaters. Many of our competitors still have EMF levels 20 to 50 times higher than our True Wave™ infrared heaters. With an average EMF level of less than 1milligauss (mg), when tested directly on the heater, it is well below the CDC’s recommendation of a maximum of 3mg. 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 EMF’s. 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.” Some health effects linked with EMF are:

  • Memory Loss
  • Depression
  • Loss of Energy
  • Irritability
  • Inability To Concentrate
  • Weakened Immune System
  • Chronic Fatigue
  • Headaches

Dr. Duncan, the founder and designer of Clearlight Infrared Sauna® models, has always ensured that the therapeutic results of your sauna are our number one priority. Seeing the research and information available on the harmful effects of EMF, we felt that if there was a chance that high levels of EMF can cause health issues, we needed to find a way to bring the levels down as low as possible. We were the first company to accomplish this with our True Wave II, far infrared heaters and True Spectrum, full spectrum heaters. Low ELF Infrared Saunas ELF (extremely low frequency) is also referred to as the electric fields or dirty electricity. There are some people that are very sensitive to ELF and have various reactions including sleep disruption and agitation and there is some link to cancer as discussed in this Occupational Safety and Health Administration (OSHA) Bulletin: All of our infrared saunas include our ELF canceling technology. While EMF is canceled in the heater itself, we have to go to great lengths to cancel the ELF from our saunas.

  1. We run the electrical wires through metal conduit.
  2. We twist the wires to cancel the ELF and EMF.
  3. We protect all electronics with foil shielding.
  4. We carbonize and ground the fishnet mesh that covers our heaters to ground and cancel the ELF.

This is all very time consuming and expensive, but we believe it’s worth it.

What type of wood is best?
Western Red Canadian Cedar is considered by many to be the best wood to use for saunas. Other woods commonly used are spruce, basswood and redwood. Western Red Canadian Cedar (WRCC) wood is often used for the following reasons:

  1. WRCC wood is a soft wood that resists cracking and splitting caused by the heating up and cooling down in the sauna. No sauna wood lasts longer than cedar wood.
  2. WRCC wood contains aromatic oils that are known for their healing and cleansing properties to aid detoxification during your sauna session.
  3. WRCC wood is naturally antifungal and antibacterial owing to the unique properties of cedar oil. This is especially important in the sauna where bodies, moisture and heat combine to make the environment perfect for molds and bacteria.
  4. WRCC wood is one of the most beautiful woods available ranging from a very light honey to a deep walnut shade.
  5. Cedar wood smells good and gives you a true sauna experience. WRCC is considered non-aromatic cedar and has a very subtle smell and is satisfying to the senses.
  6. Cedar wood can be easily sanded inside the sauna to remove any stains caused by perspiration and to bring back the fresh cedar smell.

Sauna users who are very sensitive to smells (Multiple Chemical Sensitivities) may want to consider a sauna made of white woods like Basswood. These woods have less of a smell than WRCC and may be more comfortable for people with MCS. We use Eco Certified grade “A” clear Western Red Canadian Cedar or Basswood.  All of our Clearlight Sauna® models are available in both Cedar and Basswood. Our commitment to our customers is to provide the highest quality products. Our Eco Certified woods meet three sustainability standards as part of our green initiative.

What does the warranty cover and how long is the warranty?
When buying an infrared sauna it is important to understand why a Limited Lifetime Warranty on the entire sauna is important. Our Limited Lifetime Warranty covers all of the parts of your sauna for manufacture defects for as long as you own it. Almost every other infrared sauna is only covered under a 7-year warranty or less. If something goes wrong with your sauna in year 8 the manufacturer is not obligated to provide parts for saunas older than 7 years. All Clearlight Infrared Sauna® models installed for home use are covered by our Limited Lifetime Warranty. Your sauna is warranted to be free from manufacturer defects for as long as you own it. Be sure to ask when researching infrared saunas if the company offers a True Limited Lifetime Warranty. If you are using your sauna in a commercial environment, we offer a complete 5 year warranty.
Price vs. Quality
We have looked at most of the infrared saunas on the market from the low end to the high end. There is the old saying that applies: You get what you pay for. Our sauna models are the highest quality infrared saunas on the market today. Give us a call or send us an email and we’ll tell you why our saunas are superior. Buy with confidence… buy a Clearlight® infrared sauna.
How does an infrared sauna work?
The idea behind infrared therapy is to heat your body directly with infrared heat. In a traditional sauna you are just sitting in a hot room, 180-220 degrees. In an infrared sauna, the heat is heating your body directly and 20% of the heat is heating the air. You want to heat your body core, meaning your front core and your back core. Your body absorbs the infrared heat and reacts to it. The infrared heat raises your core body temperature and stimulates your lymphatic system, immune system and your cardiovascular system. Your body’s response to that is to sweat profusely. In addition to the infrared heat triggering a profuse sweat, the water in our body also resonates with far infrared heat and this also helps with the detoxification process. With this in mind, you now understand why we stress the importance of both front and back wall heaters in an infrared sauna. If you do not have front heaters in your sauna, you will not raise your core body temperature as well and you will not receive as much of the desired effect. All of our Clearlight Infrared Sauna™ models have heaters all around you… on your front, back, sides, legs and feet.
What are the benefits of a Cedar sauna?
The traditional sauna has been made predominately from close grain cedar for many obvious reasons: 1) Cedar wood is soft wood that resists the cracking and splitting caused by the heating up and cooling down in the sauna. No sauna wood lasts longer than cedarwood. 2) Cedar wood contains aromatic oils that are known for their healing and cleansing properties to aid detoxification during the sauna. Cedarwood can also help disperse excess fluids throughout the body. 3) Cedar wood is naturally anti-fungal and anti-bacterial owing to the unique properties of the cedar oil. This is especially important in the sauna where bodies, moisture and heat combine to make the environment perfect for molds and bacteria. 4) Cedar wood is one of the most beautiful woods available ranging from a very light honey to a deep walnut shade. 5) Cedar wood smells good and gives you a true experience. “Non-aromatic” cedar is used in sauna construction and the cedar scent is very subtle and satisfying to the senses. 6) Cedar wood can be easily sanded inside the sauna to remove any stains caused by perspiration and to bring back the fresh cedar smell. 7) There is a lot of misinformation about cedar wood on the internet. The Environmental Protection Agency (EPA) put it best in their September, 1993 report: “EPA believes it is unnecessary to regulate these products because they pose little or no risk to human health or the environment…EPA is not aware of any evidence of injury to human health or the environment due to their use.” Cedar is non-toxic according to the Regulatory Information for Cedar from the Environmental Protection Agency(EPA) and World Health Organization(WHO). Click Here for the report. See the following report from an independent testing lab regarding Western Red Cedar and toxicity. Click here for the report. Please note that an extremely small percentage of the population cannot tolerate the smell of cedar wood. These people have multiple chemical sensitivities(MCS). These people cannot as a rule tolerate any aromatic oils, perfumes, shampoos or herbs. We recommend our North American Basswood Saunas for these people.
What are the benefits of a Basswood sauna?
North American Basswood is a “white” wood with a yellow to whitish color. Basswood has a very dense cellular structure making it stronger, more stable and sweat resistant. It is also resistant to cracking and splitting. Basswood is also considered hypoallergenic. It has almost no odor and is one of the only woods not considered a “sensitizer” for people with Multiple Chemical Sensitivities.
How long is the warranty on my Clearlight® infrared sauna?
We take pride in being one of the few companies that provides you with a limited lifetime warranty for residential use on the entire sauna – heaters, wood, controls and electrical. Your sauna is built in a modular fashion so replacing parts is easy. We only use the highest quality materials in each Clearlight Infrared Sauna™ model to minimize the possibility of warranty issues. Very few infrared sauna companies offer this type of complete lifetime warranty. For commercial use, we offer a complete 5 year warranty on the entire sauna.
Will I need to hire an electrician?
Standard household electrical outlets are 120 volts. Most are rated at 15 amps and some, like bathrooms or kitchens, may be rated at 20 amps. Clearlight Infrared Sauna™ models run on either 120v or 240v depending on the sauna model and the size of the sauna. Please review the specification for the model you are interested in to see the electrical requirement or contact a Clearlight® Sauna specialist at 608-630-4039. Many of our sauna models will plug into any standard household outlet. Many models require you to hire an electrician to install the proper electrical circuit.
What is the optimum infrared frequency for an infrared sauna?
The infrared frequency of a far infrared heater is determined by the surface temperature of the heater itself. The lower the surface temperature of the heater, the longer the infrared wave and the more beneficial the infrared heat will be. Our large True Wave™ far infrared heaters run at an optimal 180-200°F surface temperature producing exceptional quality far infrared heat. This means our heaters produce the majority of the infrared heat in the vital wave range of 6 to 12 microns with a good portion of wavelengths at 9.4 microns, the optimal absorption range of far infrared by the human body. Only our True Wave™ heaters combine the high infrared output of ceramic with long wave carbon infrared heat to produce the most effective infrared heaters available. You can only find this combination in Jacuzzi® infrared saunas! Our True Wave™ Full Spectrum infrared heaters are powerful 500 watt heaters that produce near, mid and far infrared. Adding in full spectrum therapy to your Clearlight Sauna® will enhance the benefits if our far infrared heaters. You will get more benefit faster in a full spectrum infrared sauna.
Do you just sell your True Wave™ infrared heaters individually?
Absolutely. We have designed an infrared heater kit and control system so you can install our True Wave™ heaters in your already existing sauna or one you are building yourself. You can even install these in that small room you’ve always wanted to convert into a sauna. The heater package consists of enough heaters for your designated space, digital keypad control and power supply, all necessary cables, cedar wood, lights and accessories. Click here for more information on our heater kits and submit your room dimensions for a quote.
Is infrared heat safe?
Infrared heat is completely safe and all objects give off and receive infrared heat. In fact, it is so safe, hospitals use similar heaters to warm newborns. Infrared is a part of nature and essential for life. The human body gives off and receives infrared in the far infrared band. When a mother rubs a babies stomach to relieve pain, it is the infrared heat from her hand that is causing the healing effect. We have tuned our True Wave™ heaters to give off far infrared in this same range for maximum absorption by your body and for maximum therapeutic benefits.
Can I put my Clearlight® infrared sauna outside?
Yes, all Clearlight Infrared Sauna™ Models can be used outside with our optional water proof cover. Because we use high-pressure bindings and precision hand craftsmanship, our sauna cabinetry can endure outdoor humidity and dryness as long as you protect it with our waterproof cover. You can also check out our sauna models specifically made for outdoors. Infrared saunas are designed to heat the human body, not the air. Only about 20% of the heat from our heaters goes to heat the air. Because of this, if you live in a place where the temperature gets below 40° F, we don’t recommend putting the sauna outside. It will take much longer for the cabin to warm up and it will not get as hot. Areas of the country experience different climates, so it’s best to consult with us before placing your sauna outside.
How will my Clearlight® infrared sauna shipped?
Your new infrared sauna will generally arrive in your state within 7-10 days from the date it leaves our warehouse in Northern California. As part of our commitment to exceptional customer service, we ship every Clearlight Infrared Sauna model with a few higher levels of service. First, our freight carrier will call to schedule an appointment to deliver your sauna. There is no worry that your sauna will arrive unexpectedly. Second, your sauna will be delivered on a truck with a lift gate to ensure that any possibility of freight damage is minimized. Third, the delivery driver will move your sauna off of the truck with a pallet jack and move it as far as they can roll it. At this point, just open up the boxes and move the wall panels into place. Setup time for all of our Clearlight Sauna® models is about 45-90 minutes depending on the size and the model. White glove service is available. If you need your sauna delivered into your house or up or down stairs, please just give us a call.
Can I receive constant infrared heat from my Clearlight® sauna?
Yes. The ideal way to use any infrared sauna is to have the infrared heaters on the entire time producing the optimal infrared heat you desire. Infrared heat is most effective at lower temperatures as sweat oils secrete at lower temperatures and this sweat is different than water sweat. Your Clearlight Infrared Sauna™ is designed to heat your body more so than to heat the cabin (about 80% of the heat heats your body and 20% of the heat heats the sauna cabin). The following is our recommendation for use of your sauna: 1) Turn your sauna on and warm it up for about 10-15 minutes. The True Wave™ heaters in your sauna will reach their optimal operating temperature in this amount of time. 2) After this short warm up time, get in the sauna and turn the thermostat up very high to ensure the heaters stay on continuously during your session. Generally, your infrared sauna session will range in temperature between 100 – 125°F. 3) Sit back and enjoy your sauna session. Since the key to infrared therapy is heating your body core, you will find that you sweat more sitting up in the sauna with your back lined up with the back wall heaters heating your body core from the back. This positions you in such a way that the front wall heaters will be heating your front body core. 4) During your session the temperature will slowly climb inside the sauna cabin. Remember, your Clearlight Infrared Sauna is heating your body more so than heating the air. 5) Stay Well Hydrated. We emphasize this because it is essential to stay well hydrated when using your sauna. It is estimated that 70% of people are dehydrated. When you are dehydrated, your body holds on to water and will not allow you to sweat very much. It is recommended to drink water before you get in the sauna and bring a quart of water into the sauna with you and drink it during your session. Don’t be fooled by other manufacturers that offer constant infrared heat by reducing the output of their heaters. At the reduced output you are not receiving optimal infrared heat.
Is there anywhere I can try a Clearlight® sauna before I buy one?
Yes! Feeling the healing warmth of our infrared saunas is truly a fantastic experience. And if you live in the Madison, Wisconsin area, there is an infrared sauna studio near you! Contact Jenerate Wellness to schedule a sauna session or book one online.
Do all Clearlight saunas come with healing chromotherapy?
Our Clearlight Sanctuary models come standard with our Medical Grade Chromotherapy and our Clearlight Premier includes our Standard Chromotherapy with 15 LED lights. You can, however, upgrade any Clearlight Premier sauna to our Medical Grade Chromotherapy with 96 LED lights. With high intensity output, you’re going to benefit faster because you’re bathed in light. You can set an individual color or select auto mode, where the lights will automatically switch between colors every 25 seconds. We have also added a dimmer switch to the remote control for your comfort. View all of our sauna models.

A General Historical Overview of Infrared Saunas

For many years only high quality far infrared saunas dominated the infrared sauna market. Craftsmanship, for the most part, was very high. Woods used were Western Red Canadian Cedar and quality white woods such as Basswood, Spruce and Aspen.  The majority of infrared heaters used were ceramic and metal, with ceramic being the preferred type because of higher infrared efficiency and infrared output. There were rigid quality control of woods and glues used.  Electrical safety and consistent customer care had been the hallmarks of our industry at that time.  There were less than a handful of manufacturers in the entire US. This was the state of the industry that we grew our company in.  Quality was everything.

Over the last 10 years, however, as the internet expanded, low quality overseas manufacturing spawned numerous upstart sauna companies importing containers of infrared saunas with little to no understanding of the therapeutic benefits of infrared therapy.  They were selling a wooden box with heaters.  Also, quality and after sales service did not seem to be a big concern.  They offered low cost and low quality saunas on the internet and at big box stores… saunas as a cheap commodity.

We ordered different models from a few of the larger manufacturers and were immediately appalled at the quality of materials and construction and lack of safety down to even the basic wiring. The controls and heaters were cheap and substandard. The aesthetics were all wrong. Some had noxious odors from toxic glues being used in the manufacturing process. Others had horrible smells from the wood itself. Some of the woods had not been finished sanded; rough to the touch as you passed your hand over it. We also found staples, mismatched veneers, dangling and bare wires… not a quality product!

What was even worse was that most of these saunas had a combination of hazards ranging from high EMF levels being emitted from the heaters to toxic fumes. It was also evident that the manufacturer didn’t understand the basics of how infrared therapy works with the human body as there were multiple design flaws.  For example, many of these companies did not know where to place the heaters for optimal effectiveness and healing, a critical mistake.  Heaters positioned above the head do no good as it is the infrared wavelengths coming off the heaters directly that do the healing in an infrared sauna. Positioning heaters above the head just waste infrared energy that could be better used in the front of the sauna, or by the calves and sides of the body. This is a big functional mistake. The idea behind infrared therapy is to heat your body with the proper wavelengths so it is important to heat your front, back and sides. Without proper heater placement, you will only receive partial benefit.

We take a different approach, with heaters kept low to keep the infrared heat aimed at your body and we totally surround you with infrared heat.  There is no wasted infrared heat up over your head.  You will get more benefit faster with the maximum amount of infrared heat being absorbed by your body.

When designing Clearlight Sauna® models the sauna design, new technology, idea or manufacturing process must pass a few critical tests: Does it make rational sense to help to heal the human body?  Will it help our customers increase their overall wellness and enjoyment of their sauna?  Is it safe and does it cause no harm?  If the answer is no on any of these, then we simply do not do it.

We believe purchasing a Jacuzzi® infrared sauna is one of the best investments you can make for your health and longevity.  We pay close attention to every detail from start to finish to ensure that your sauna is of the highest quality materials and construction.  We back these words with our Limited Lifetime Warranty.
