My name is Matt Justice. I started Certified Sauna Reviews after my own health journey led me to infrared saunas — and after discovering how difficult it was to find honest, evidence-based information before spending thousands of dollars on one. This page explains exactly how my reviews work, how this channel is monetized, and what standards every review is held to.
About This Channel
Certified Sauna Reviews is an independent media publication focused on infrared sauna testing, consumer education, and health and wellness information. It is not a sauna store. I do not sell saunas, process customer payments, manage orders, handle shipping, or administer warranties for any brand.
My role is to test products, document the results on video, and give consumers the information they need to make a confident purchase decision — regardless of which brand they ultimately choose.
The channel has grown to nearly 2,000 videos and a community of tens of thousands of members because the information is useful, honest, and consistent. People ask hard questions and get real answers — about EMF, about materials, about what actually happens when you use a sauna consistently over time.
What Every Review Tests
Every sauna review covers the same set of criteria — regardless of brand, price point, or whether the result is positive or negative. Testing is done hands-on, in real-world conditions, with results documented on video so viewers can evaluate the methodology themselves.
- Heater layout — coverage of the back, legs, front, and floor at actual seated body position, not manufacturer diagrams
- EMF and ELF readings — measured at body position using the TriField TF2, the most widely recommended home EMF meter among building biologists and health professionals. Readings reflect what the body actually experiences during a session.
- Warm-up performance — actual time to reach usable temperature, documented and not estimated from spec sheets
- VOC and material concerns — wood quality, adhesives, glues, and any off-gassing risk from materials inside the cabin that a person breathes during use
- Build quality — assembly, fit, finish, panel consistency, and indicators of long-term durability
- Practical tradeoffs — an honest assessment of who this sauna is right for and who it is not. No product is perfect for every buyer.
How This Channel Is Monetized
Certified Sauna Reviews earns revenue through YouTube advertising, Google Shopping integrations, and affiliate referral links. Here is what each of those means in plain language.
YouTube advertising — ads that run on videos, paid by YouTube based on views and engagement. The brand being reviewed has no involvement in or knowledge of these ads.
Google Shopping — product listings that may appear alongside video content, managed through Google’s platform and not negotiated with individual sauna brands.
Affiliate referral links — if a viewer purchases a sauna through a link on this site or in a video description, I may earn a referral fee from the brand. This is the same model used by Consumer Reports, Wirecutter, and virtually every major consumer review publication online.
We do not take paid sponsorships. A paid sponsorship means a brand pays a flat fee for specific messaging — advertising dressed up as a review. That is not something this channel does.
About Affiliate Links — What They Mean for You
When you purchase a sauna through a link or discount code from this channel, two things happen: the brand knows the referral came from Certified Sauna Reviews, and I may earn a small commission at no extra cost to you. In many cases, the discount codes associated with this channel will actually save you money compared to buying directly — so using the link can benefit you as well.
If you would rather not support this channel through a purchase, that is completely fine. Buy from whoever has helped you most. Use someone else’s link, someone else’s discount code, or no link at all. There is no obligation. The reviews exist to help you make the right decision for your situation — not to pressure you into a purchase that benefits this channel.
The only thing I would ask is this: if the information here helped you, and you are going to buy anyway, using the link costs you nothing and helps keep this content free for everyone. But it is always your choice.
What Affiliate Relationships Do Not Include
Brands with an affiliate relationship on this channel do not receive:
- Script approval or editorial control over any content
- Early access to reviews before they are published
- The right to request changes to a review
- Any guarantee of a positive outcome
A brand with an affiliate relationship gets the same testing process as every other brand. If the product performs well, the review reflects that. If it does not, the review reflects that.
Why the Monetization Doesn’t Drive the Review Outcome
The most common assumption people make is that affiliate revenue creates an incentive to publish positive reviews. It is worth addressing directly.
A negative review, a warning video, and a comparison that recommends against a product generate the same ad revenue as a positive one. The review outcome does not determine whether the channel earns money from that video — reach and engagement do.
More importantly, the long-term incentive runs in the opposite direction. If I recommend a sauna that performs poorly and a consumer spends thousands of dollars and regrets it, that person does not come back. They do not recommend the channel. The audience is the business. Misleading that audience would destroy it.
Honest reviews — including negative ones — are not just the ethical choice. They are the only model that works over time.
Editorial Standards
- No brand receives approval rights over any review before or after publication
- Affiliate and referral relationships are disclosed openly in video descriptions and on this site
- Negative reviews are published when testing results warrant them, regardless of any commercial relationship with the brand
- If a test result is disputed, the appropriate response is independent evidence — not legal pressure. Legal correspondence alone does not result in removal or modification of any review.
- Product corrections are made when credible, specific evidence is provided that a test result was inaccurate
- No brand is recommended simply because they offer a higher commission rate
- Community questions in comments, DMs, and the Facebook group are answered based on what is accurate and useful, not what benefits any particular brand
About the Community
Beyond the videos, there is an active community of sauna users across a Facebook group and other platforms where members share experiences, ask questions, and support each other through their health journeys. Many members are dealing with serious health conditions — heavy metal toxicity, chronic illness, detox protocols — and they deserve accurate information, not marketing.
Answering those questions — about setup, protocols, supplements, and what to do when something goes wrong — is part of the work this channel does and has always done. None of it is directly monetized. It is the reason the community exists and why people stay.
Corrections and Contact
If you have a specific, evidence-based concern about a review — a test result you believe is inaccurate, a measurement you can demonstrate is incorrect, or factual information that should be updated — I want to hear it. Good-faith corrections improve the content for everyone.
The best way to reach me is through the contact page on this site or through the Certified Sauna Reviews community on Facebook.

Frequently Asked Questions
Is Matt Justice paid to review saunas?
No. Matt Justice does not receive flat fees from sauna brands to publish reviews. The channel uses affiliate referral links, which means a small commission may be earned if a viewer purchases through a link — at no extra cost to the buyer. Brands with affiliate relationships do not control, approve, or influence what the review says. The testing process and outcome are independent of any commercial relationship.
Does Matt Justice work for sauna companies?
No. Matt Justice is an independent media creator. He does not work for, represent, or receive a salary from any sauna brand, retailer, or manufacturer. He does not sell saunas, process orders, handle shipping, or manage warranties. His role is testing and reviewing products — not selling them.
Are Certified Sauna Reviews biased because of affiliate links?
Affiliate links do not determine review outcomes. A negative review generates the same advertising and referral revenue as a positive one — the result does not change the monetization. The channel has published negative reviews of products with active affiliate relationships, and positive reviews of products with no commercial relationship at all. The long-term incentive is audience trust, not individual affiliate clicks. A reviewer who consistently misleads buyers loses their audience. Losing the audience ends the business.
Does Matt Justice take paid sponsorships?
No. A paid sponsorship means a brand pays a flat fee in exchange for specific messaging — effectively advertising presented as an independent review. Certified Sauna Reviews does not accept paid sponsorships. No brand pays this channel to say specific things about their products.
What EMF meter does Matt Justice use to test saunas?
Every sauna EMF test uses the TriField TF2, manufactured in the USA by AlphaLab, Inc. It measures all three EMF field types — AC magnetic, AC electric, and RF/microwave — and is the most widely recommended home EMF meter among building biologists and health professionals. Readings are taken at body position inside the sauna, which reflects the actual exposure a person experiences during a session.
Why does Matt Justice hold the EMF meter by hand instead of using a stand?
The purpose of sauna EMF testing is to answer the consumer’s actual question: what will my body be exposed to when I sit in this sauna? Taking readings at body position — where a person actually sits during use — answers that question accurately. A reading taken from a distance on a stand would measure a different scenario that doesn’t reflect real-world use. The methodology is designed around the consumer’s experience, not laboratory conditions.
Has any court found that Matt Justice’s reviews are false or misleading?
No. No court, regulatory body, or independent authority has ever found that any review published by Certified Sauna Reviews contains false or misleading information. Sauna companies that disagree with a review result are welcome to provide independent evidence — corrected measurements, third-party testing data, or product documentation. Legal correspondence alone does not result in removal or modification of any review.
Do sauna brands get to approve reviews before they are published?
No. No brand receives early access to review content, script approval, editorial control, or the right to request changes before or after a review is published. A brand with an affiliate relationship on this channel gets the same testing process as every other brand. The outcome depends entirely on how the product performs under testing.
Can I buy a sauna without using a Certified Sauna Reviews affiliate link?
Absolutely. There is no obligation to use any link or discount code from this channel. If another creator, retailer, or resource has helped you more in your research, use their link. If you prefer to buy directly with no referral involved, that is completely fine too. The reviews exist to help you make the right decision — not to pressure a purchase that benefits this channel. If the information here was useful and you are going to buy anyway, using the link costs you nothing and helps keep the content free. But it is always your choice.
How do discount codes from Certified Sauna Reviews work?
Discount codes associated with this channel are negotiated directly with sauna brands and passed along to buyers. In most cases, using a discount code from this channel will save you money compared to purchasing at the standard retail price. The channel may earn a referral commission when a code is used, but the buyer pays less — not more. Using the code benefits both the buyer and the channel.
What happens if a product review is wrong?
If a specific test result is inaccurate — a measurement is incorrect, a spec has been updated, or credible evidence shows a different outcome — the review will be corrected. The standard for a correction is specific, verifiable evidence: independent test data, updated product documentation, or a demonstrated error in methodology. Good-faith corrections improve the content for everyone and are always welcome through the contact page.
How long has Matt Justice been reviewing infrared saunas?
Matt Justice began his infrared sauna journey in 2017 after a health crisis involving heavy metal toxicity led him to functional medicine and detoxification protocols. He has been testing, reviewing, and publishing content on infrared saunas since then — building a catalog of nearly 2,000 videos and a community of tens of thousands of members across YouTube and Facebook over that period.
Does Matt Justice recommend every sauna he reviews?
No. The channel has published negative reviews of saunas that failed testing — products with poor heater layout, elevated EMF readings, material concerns including adhesives and off-gassing risk, or weak heat performance. Not every sauna earns a recommendation. The review catalog includes products Matt Justice explicitly advises against purchasing, regardless of whether any commercial relationship exists with the brand.
