C4 Recovery Vs. M-Cryo Elite: A Quick Overview

The US cryotherapy market is quickly expanding and is expected to be worth $6.72 billion by 2026.1 This is mostly due to technological advancements and enhanced safety of the machines.

The cryotherapy machine standards and regulations are also stricter. This has resulted in wide acceptance of cryotherapy services. Quality machines are also easily accessible.

Here’s a quick review of the C4 Recovery vs. M-Cryo Elite cryo chambers – two quality cryo machines currently in the market.

Comparison of the C4 Recovery vs. M-Cryo Elite Cryotherapy Machines

Their Similarities Explained

Country of origin

The C4 Recovery and M-Cryo Elite cryotherapy machines both come from the USA. M-Cryo Elite has manufacturing plants in Richardson, Texas, while the manufacturer of the C4 recovery is in various states. This includes California, Utah. Michigan, Minnesota, and Tennessee.

All materials come from local sources, which makes it easy to have repairs done. There are no risks of unavailable or delayed replacement parts. You can also easily get assistance with installations and customer support.  

What Are Their Main Differences?

Cooling Method

The C4 Recovery cryo-chamber uses a refrigeration cooling method. This is where oxygenated air is cooled and supplied to the cryo-chamber.  It is very safe as the risk of inhaling harmful gases is considerably reduced.  This also makes this type of cooling perfect for whole-body cryotherapy machines.

The M-Cryo Elite, on the other hand, uses a nitrogen cooling method. This is where liquid nitrogen serves to cool the cryo chamber. With this type of cooling, your clients have to keep their heads outside the chamber. 

Warranty Period

The C4 Recovery has a 1-year warranty, while the M-Cryo Elite has a 2-year warranty. This only covers breakdowns that come from flaws in the manufacturer’s parts and systems. Thus, you may have to incur the cost of any man-made damage.

The Sale of Goods Act protects you from taking the liability of such faults. It, however, doesn’t define the time period for the manufacturer’s guarantee. Studies have shown that the generally accepted time is 6 years.2

Safety Features

Safety is one of the major concerns of cryotherapy clients.  

Both systems have safety measures in place, but the M-Cryo Elite has onboard O2 sensors. They control the level of oxygen in the cryo chamber. This ensures that your clients don’t suffocate during sessions. 

Both machines don’t require a dry-out time. 

Levels of Efficiency

The M-Cryo Elite has an electronic lift system and can handle 15-20 sessions per hour. Since it’s nitrogen-cooled, it can only service one person per session. 

The C4 Recovery, on the other, can handle up to 12 treatments per hour. It accommodates 2 people per session. 

C4 Recovery Vs M-Cryo Elite: Which One Should You Go For?

Both cryotherapy machines have their distinct benefits. Thus, the choice boils down to your unique business needs. C4 recovery is perfect if you’re looking for a refrigeration-cooled machine. Conversely, The M-Cryo Elite is one of the best nitrogen-cooled machines.

Cryo Innovations XR Cryotherapy Machine vs Impact Cryo Machine

Cryo Innovations manufactures the XR cryotherapy machines. The headquarters of this company is in Newport Beach in California. The machine’s core marketing point is being among the safest cryo machines available. 

Impact Cryotherapy manufactures the Impact cryo chamber and is based in Atlanta, Georgia. The company boasts of well-designed cryo chambers.

Cryo Innovations XR Vs Impact Cryo: A Quick Overview

Let us take a quick look at some of the key distinguishing factors between the two whole body cryotherapy machines.

Safety Features

Starting with the XR, the machine has extremely well-thought safety features that make it a favorable choice as an investment. It has safety emergency buttons that, when activated, cause the machine to shut down automatically, ensuring the safety of the user. 

These features make the machine a preferred choice for gyms, spas, and small businesses in general.

Other safety features

  • They have a two-step fingerprint authorization by an approved operator and a user.  
  • It requires the presence of an operator who touches the screen in 30-second intervals to verify their alertness regarding monitoring the user.
  • They are designed not to operate if a user’s head is below the top opening. The door automatically opens, stopping the nitrogen flow.

Unlike the XR, there is no explicit mention of impact cryotherapy’s key safety features. However, it provides features like ease of door operation from the inside.

The machine also turns off automatically after the three minutes required run-time. A key safety measure of the Impact machine is training users on the protocol. Full trained Impact employees also install the machines.


The XR machine has very advanced digital features and uses a Wi-Fi-enabled connection to update regularly and perform software diagnostics.

Moreover, it comes with management features for owners with businesses in different locations that help them manage all machines from one device.

The feature also makes it easy to transfer client data from one location to another seamlessly.  

The Impact Machine works with the company’s software called smart sauna. The software integrates the user interface and monitoring system along with safety protocols.  

It enables the machine to communicate with the technician and also ensures that the machine runs without hitches.


The XR machine has a beautiful compact design and does not require a huge space. LED lights in the interior light the cabin with beautiful colors to the user’s comfort.

It comes with a three-year warranty.

The Impact cryotherapy features a unique design and comes with an adjustable height riser platform to cater to users of different heights. The interiors are anti-microbial cryogenic panels. It has a one year warranty.

Cryo Innovations XR Vs Impact Cryo: Final Words

When it comes to design, both machines are well designed and built. The significant difference between them seems to be in their safety measures. 

Even though both manufacturers have gone to great lengths to keep the user safe, the XR cryotherapy machine has far more elaborate safety features.

Will Cryotherapy Help Your Sex Life?

This Valentine’s Day you may find yourself tempted to buy roses and chocolates for your loved one. But would a trip to a cryotherapy chamber be more romantic? Can cryotherapy help your sex life? Yes, and in more ways than one! Furthermore, cryotherapy and its resulting benefits can help lead you to a happy and healthy sex life and give you the boost that you and your partner need.

Getting freezing cold this Valentine’s Day might just help your sex life.

Inflammation and Sex

One of the greatest frustrations for a healthy sex life is erectile dysfunction (ED). According to Harvard University ED is caused by an insufficient blood flow.¹ This is often caused by inflammation of the endothelial cells that line the inner layer of arteries and veins. In an effort to study how anti-inflammatory medications affect the endothelial cells researchers studied how common NSAIDs affected ED. The question was basic: will an anti-inflammatory pill reduce endothelial cell inflammation and cure ED? Unfortunately not. In fact, it made it worse. According to the American Urological Association not only was the ED made worse, it brought higher levels of endothelial inflammation.²

Exercise and Inflammation

Inflammation as an issue can seriously derail your sex life! Muscle soreness is no fun when you are trying to be intimate with your partner. But one common problem with athletic people is muscle soreness due to inflammation. It is common for people to take an Advil or aspirin after a hard workout, but this can make ED worse in some men. Cryotherapy can provide quick and drug-free relief from inflammation and hopefully remove any need for an after-workout aspirin. Tylenol can substitute for those who still need a bit of pain relief after exercise but who are worried about ED complications as it is not an NSAID.³

Cryotherapy and Women

A woman’s sex life can improve with cryotherapy in a number of ways. Cryotherapy helps build stronger collagen networks, resulting in less wrinkles. The skin benefits alone help me feel better and more confident in myself. Cryo helps me keep a clear complexion and even skin tone over my entire body. After a difficult workout I am often tired and I just want to rest. But after a cryotherapy treatment I am less sore, invigorated with energy, and I feel happy that I did something for myself. This helps me be a better partner with my spouse and maintain a feeling of closeness.

Cryotherapy and Overall Health

Cryotherapy added to an ordinary exercise program can have extraordinary benefits. The first and foremost benefit is reducing inflammation throughout the entire body. Additionally, less sore muscles means less discomfort and an improved desire to work out harder. Healthline reported that exercise can improve a couple’s sex life in 23 different ways. Accordingly this includes benefits that cryotherapy augments, including:

  • Less stress and anxiety
  • Increased stamina
  • Improved blood flow
  • Stress Relief

Cryotherapy and Stamina

Stamina is built by stressing the body through exercise and training the body to endure more intense and longer lasting exercise over time. Regular exercise alone builds stamina; however, pairing cryo 2 or 3 times per week helps build stamina because it allows you to work out harder with less soreness. The majority of people who fail at an exercise routine stop working out because of pain or soreness. Cryotherapy reduces soreness and exercise fatigue, so your 30 minute workout can easily become a 45 or 60 minute exercise routine.

How are you spending this Valentine’s Day? A little cold might heat things up!

The Final Valentine’s Verdict?

Most of the time people are conflicted about what to do for their loved one on Valentine’s Day. The best gifts are those that show thought about a future together. Surprise your partner with something he or she may have never tried: whole body cryotherapy! It will be exciting, fun, and you will both laugh at the experience. Regular cryotherapy can help your sex life by helping you reduce inflammation, boost energy, and feel better about yourself. That is a gift any cupid would love.

Best Cryo Chambers of 2021

After the whipsaw of the 2020 many small business owners are beginning to reopen or restart their business ventures. The whole body cryotherapy market has felt a surge as clients seek out cryotherapy for immune system benefits.¹ Is now the right time to launch a cryotherapy business? Here is our take of the best cryotherapy chambers and cryosaunas for 2021.

How Did We Base Our Decisions?

To keep ourselves objective our findings were based upon measurable features of the cryotherapy machines. We weighed the field to determine our top three choices based upon the following questions:

  1. How much would this machine cost to purchase and run for one year, assuming 20 sessions per month (session base at $35).
  2. In a worst-case scenario what machine provides the safest experience and/or reduces owner liability the most?
  3. Response time of customer service inquiries.
  4. Warranty terms


Known for an abundance of safety features and lowest nitrogen consumption the XR leads the top of the list for cryosaunas. We chose this unit for a handful of reasons:

  • Best nitrogen consumption in class at 3-5 L per session
  • Highly mobile, easy to move room to room on 8 wheels
  • Remote monitoring via cloud software
  • California based support center (very responsive in our tests)
  • Consistent performance and cold temperature
  • Fingerprint security for operator and client
  • Client facing screen showing session statistics and video

Cryo Innovations proved unique in our study also for their ability to scale locations. A single business owner with 4 locations can monitor each chamber simultaneously from anywhere in the world. Additionally every person who operates or uses the chamber must log themselves in with a fingerprint. This provides more safety than any other chamber, and prevents unscrupulous employees from giving away sessions without payment.


The Cryo Arctic has shown great promise, especially in the area of esthetics. It’s cool lines lend themselves nicely to any space. Powered by a nitrogen/electric system the Arctic provides a cold cryo session without any exposure to nitrogen gas. Our other favorite features are:

  • Sleek design available in white or black
  • Bluetooth speaker system
  • Moveable window that provides for true whole body or partial body treatments
  • Client facing screen displaying remaining time

Two concerns kept the Arctic from the #1 slot: nitrogen consumption is a whopping 12L per session, and it is an expensive machine. Many entrepreneurs have noted that they could purchase two cryosaunas for the price of the Arctic.


The German made LifeCube is an eyecatcher. Standard models have an appealing shape, but LifeCube can design any shape you may like within reason. Available in single or double-room styles, this electric chamber cools down to -166°F. Other features we loved are:

  • Chamber is easily controlled with an app from a phone.
  • Multiple color options available.
  • Surround sound system
  • Automatic door opener

As it is an electric chamber it is categorically more expensive than a nitrogen powered chamber. If pricing concerns are not a problem this may be the excellent addition for your business. One concern we noted is their customer service. We had two staff members contact LifeCube and both inquiries took over 48 hours to receive a response. While not a deal breaker as the company is based in Germany, it may not be comfortable for a business owner who needs help to not receive it immediately.

  1. While cryo itself does not “boost” the immune system it does help people continue to live active lifestyles. This in turn can help develop a stronger body, and potentially a better immune system.

Cryo Innovations: XR Cryotherapy Machine

The XR cryotherapy machine has a reputation for being one of the safest whole-body cryotherapy machines.

They are based out of Newport Beach, California (USA) and their CEO is Keith Scheinberg.

He highlights on their website that if this machine was in the market in 2015, it would have prevented the cryotherapy tragedy that saw a woman lose her life inside a cryotherapy chamber.1

But how safe is the XR really?

Here’s an overview of this cryotherapy machine and its defining features.

XR Cryotherapy Machine – Overview

Cryo Innovations claims to be one of America’s top experts when it comes to whole body cryogenic technology.

This company takes pride in being able to promise, and deliver innovation in terms of tech and safety features.

Cryo Innovations XR protects users and accommodates the business needs of customers.

Innovative Safety Features

To prevent accidents, this cryotherapy machine has safety sensors that, when triggered, cause the machine to immediately shut down.

The machine’s door also has proximity sensors that cause the nitrogen valves to stop when it’s open.

Other safety features include:

  • Thermal imaging to provide real-time reports of the customer’s vitals and to detect the presence of a client’s head.
  • Shut off valve and stop button that makes it possible to stop the flow of nitrogen during an emergency.
  • A monitoring system that shows the operator the client’s diagnostics including the pulse, blood oxygen levels, and temperature levels.

This machine also comes with gloves, robes, and soft protective boots.

Tech Features

This machine has health waivers digitally stored to minimize your business’s liability and has a point of sale system that reminds your clients to renew or upgrade their subscriptions.

The WIFI connectivity ensures you get live diagnostics and enables the software to update automatically.

If you have multiple-location cryotherapy businesses, then you’re definitely going to enjoy the location management features.

They allow you to monitor your franchise from one device and make it possible to transfer customer files across different locations.

MMA Fighter Hurt In Cryotherapy Chamber

On November 26, 2020, professional MMA fighter Athena Martinez was badly hurt in a cryotherapy chamber in Syndey, Australia. She suffered severe burns on her legs resulting in large frostbite-type blisters. Her injury required immediate surgery and skin grafts, all documented on her social media and picked up by news outlets worldwide. It is the worst injury made public after the fatal injury suffered in 2015 in Las Vegas. The cryotherapy industry will suffer another setback. It is only a matter of time.

Was CryoMed To Blame For The Athlete Hurt in the Cryotherapy Chamber?

No. CryoMed as a manufacturer is unlikely at fault, but someone was hurt in their cryotherapy chamber. Whenever someone suffers an injury in a cryotherapy chamber the brand of chamber unfortunately receives the blame. All chambers we review are safe to operate, although some have more features than others. The problem is either with the operator acting negligently or the system itself failed, which itself is rare. According to Australian news sources Martinez was provided a six-minute session (i.e., two sessions of three minutes back-to-back).

After Athena Martinez was hurt in the cryotherapy chamber she stated publicly on her Instagram that she was neither told she was receiving a double session nor aware that it was happening. But Martinez is not new to cryotherapy and has used cryo many times according to her trainer and people familiar with the matter. Could a “double session” have even happened? Not according to the manufacturer. The CryoMed has an electric lift that automatically lowers at the end of the 3 minute session. Anyone in a cryosauna would know if the lift was operating. If the double session occurred the lift would lower, stop, and then rise again before the second session began.

Was The Operator To Blame For The Athlete Hurt in the Cryotherapy Chamber?

Why she was unintentionally hurt in a cryotherapy chamber is being debated. It appears the operator was improperly trained or neglected the training provided. 3 minutes in a nitrogen chamber is the industry standard. From our preliminary investigation it appears the operator ran two sessions while Martinez was aware of that fact. But operators can only work on the training they have received. Companies must train their staff rigorously and educate them on why the training matters. Too often we have reviewed training products and found them too simple. This creates a lazy attitude towards cryotherapy and ignores the dangers cryo can present. This event is all the more reason to train your staff well, and train them yourself.

How Dangerous Is Cryotherapy?

Just like any treatment of the human body cryotherapy poses dangers if people ignore proper safety protocols. But the incidence of injury from cryotherapy is much lower than many people think. More injuries happen from treadmills, bicycles, and even tanning beds when people are using them appropriately. Unfortunately cryotherapy receives more attention simply because it is an exotic and sometimes controversial therapy and many people are unaware of how it actually works.

How You Can Talk To Customers About It

This event has been receiving less attention than the Las Vegas death in 2015 of Chelsea Ake-Salvacion, but the attention it is receiving is not good. Some manufacturers and reps of electric chambers have used this as marketing fodder, which we do not support. If your customers ask about what happened tell them the truth. Use it as an opportunity to explain why sessions in nitro chambers are 3 minutes maximum. Explain that events like this remind us about why a customer’s skin must be dry and they must wear gloves and slippers. Here are some potential talking points:

  • Yes, that happened, but that is exactly why we always make sure you are dry and that you wear the right PPE. We want to keep you safe.
  • Unfortunately someone was injured, but it only happened because they didn’t follow the rules.
  • This is why we always ask you if you are dry and if you are healthy. Cryotherapy is a serious therapy, and we want you to be totally safe.

Since 2015 our industry has suffered a fatality, a very public injury with Antonio Brown, and now this severe injury to Ms. Martinez’ legs. Be honest with your customers about what is happening, but also assure them that you are doing your best to keep them as safe as possible.

Cryotherapy Machines from Finland: An Overview of the Cryocabin

Designed specifically for commercial use, the CTN Cryocabin from Finland is a great choice for your business. This cryotherapy chamber has a great design, it’s safe, easy to install and operate, and comes with excellent customer service. The exquisitely crafted chamber comes with a sturdy carbon film exterior wall and a wood interior. Let’s dive a little deeper and look at an overview of the Cryocabin.

Overview of the Cryocabin

Space and Mobility

The CTN Cryocabin aims to give the user the best experience possible without them feeling too cramped. It is a small enough machine to fit into most standard doorways without any strain. Each unit also comes equipped with rollers that are incredibly handy when lugging around the 415 kg machine. This makes it easy to take it to expos, trade shows, and even make home visits for clients who prefer a more homey experience. The units typically come in either grey or white colors.

Precise Cold Diffusion

This cryo machine evenly distributes the cold through the chamber’s multi-directional sprayers. With this, it can control the flow of air and provide the client with a directional spray that suits their preferences. It also makes adjustments to the airflow so that users don’t have to keep rotating for even air distribution. This feature ensures that your clients don’t experience any focused cold air on their feet which typically causes a stinging sensation.1  

Cryocabin Safety Features

The CTN Cryocabin comes with two cooling options, liquid nitrogen or liquid air. While they are both safe, liquid air advocates claim that it is the safest option since liquid air is essentially gas that has been condensed.

Finland imposes strict quality standards that are among the highest in the world and each Cryocabin unit has to meet these standards before it can be shipped.

Here are some of the criteria that the cabin must meet:

  1. The backpressure has to be completely self-regulating to enable it to operate with tanks whose pressure ranges from 22 to 28 psi
  2. In the event that a user lowers their body below the manufacturer’s recommended level, a sensor should be able to detect this, stop the gas, and suck out all the gas already in the chamber to keep them safe.
  3. The cabin’s software should be able to detect the location of the user’s head. The cabin must be at a height that offers optimal levels of comfort.

This chamber also comes with 100% breathable air and emergency shutdown to ensure its user’s safety should anything happen.

Cryocabin Price and Efficiency: Is It Worth the Hype?

This cryotherapy machine is one of the most efficient chambers in the market, consuming an average of 1L per minute. It also comes with a warranty of up to 3 years and can provide more than 100 sessions per day, making it perfect for busy premises.

COVID and the Cryo Arctic

With California and numerous states enforcing stricter COVID rules the question about infection rates has reached cryotherapy. Specifically, how can small businesses that use the popular Cryo Arctic enclosed chamber protect their customers?¹

Is the air inside “safe” without a mask?

Masks Are Never Perfect

Wearing masks for skin protection in cryotherapy is a matter of preference. Some wear masks to prevent cold air inhalation or to protect their lips, others do not. But with COVID making a comeback we must ask: how can we sanitize the air in a Cryo Arctic? If someone with COVID or any respiratory illness does a cryo in an enclosed chamber, how long must the chamber be open to clean the air? What if a person with COVID—who shows no symptoms—infects the chamber before an elderly person arrives?² As a business owner and a medical professional I am concerned for myself and every Arctic owner who is struggling.

Air Quality In Cryo Is The Future

People have been wearing facemasks for nearly a year now, and frankly there is no end in sight. Cryo in the era of COVID now requires hospital-level wipedowns, single-use feet and hand coverings, and facemasks for everyone. Apart from touchpoints cryo consumers have become aware that the air they breathe is concerning. Cold air simply will not disable the virus; there must be an air-out time in between sessions.

What Alternatives Do We Have Now?

For current Cryo Artic owners it may help to keep the door open after a session with a floor fan circulating air through the chamber. Other measures may put your customers at ease:

  • Limit cryo to appointments only to prevent uncontrollable traffic
  • Open all windows and keep the chamber window open when not in use
  • Invest in a hospital grade air purifier
  • Sanitize the entire room with a disinfectant fogger at the end of the day

For small business owners who are uncertain on what type of chamber to add it may be best to review models of cryosaunas that allow the customer to keep their head out of the chamber. The future of our industry is unknown, and investing in an enclosed chamber right now may bring more headaches than anticipated.

What About N95 Masks?

Are N95 masks the solution for cryotherapy? Probably not. N95 masks are effective only if they are fitted and worn correctly. Just buying a box of N95’s is not sufficient. They must be fitted by trained specialists who ensure a correct fit and seal is made. If this was possible nationwide for everyone it would be ideal, but COVID has taught us that it is not. These special masks are most effective in clinical situations by those who are trained to wear them. In a cryo setting a surgical mask or a mask of cloth can provide protection from the cold, but they are not perfect.

This N95 is ineffective as it is too big and not sealed to his face because of facial hair.


  1. I am using Cryo Arctic in this example as it is more popular than other enclosed whole-body chambers. It is not an attack or disparagement of Cryo Arctic at all.
  2. Masks have shown promise in reducing the transmission of COVID when they are worn correctly.

Do Not Wear Clothing During Cryotherapy!

I love cryotherapy and try to get my cryo in three times per week or more. At home this is easy, but when I travel it can be challenging to find a cryotherapy provider in an unfamiliar city. Despite the challenge I do enjoy trying different chambers and seeing how cryotherapy is growing in the United States. In pre-covid days my goal was to try every chamber and I nearly have. But I noticed a concerning trend in some shops that offered enclosed chambers: people wearing clothes while doing cryo!

How is this cryotherapy? Will this eventually harm the industry?

Wearing Clothes Is Not True Cryo

Cryotherapy is best performed wearing only one’s undergarments. As a woman I prefer a sports bra and my underwear or a bikini bottom. But I am seeing more and more of people wearing outdoor clothing inside the chamber. I recently came across this problem on the east coast where I found a US Cryo C1 Recovery Chamber. I love US Cryo products and was excited, but I saw something very odd when I arrived: two women wearing their clothes inside the chamber! When I asked the operator why they were clothed she gave a conflicting set of answers:

  1. “They said they didn’t like the cold so they were not going to wear their swimsuits.”
  2. “They are still okay because their clothes are loose.”

Specifically these two young women were both wearing the proper PPE of slippers, gloves, and a facemask. But they also had on knee high socks, running shorts, beanies, and t-shirts. The only skin exposed to the cold was their mid-thigh, forearms, and neck. While this could be proper attire for a morning run in city it actually defeats the purpose of doing cryotherapy.

True Cryotherapy Requires Skin Exposure

I love cryotherapy for its therapeutic effects. From a nurse’s standpoint I know that vasoconstriction in a cryo setting simply won’t happen if a person is wearing clothing. The body’s heat will remain trapped–even under a t-shirt–and prevent the cold from doing its work. I personally wear only my undergarments, slippers with low socks, and gloves. That’s it. I want to provide my body with the greatest amount of exposure to the cold to reap the greatest benefits of cryotherapy.

Wearing Clothes Is Bad For Business

From a personal standpoint I can see a cryo business allowing a paying customer to enjoy cryo however they want. But ultimately that is bad for the business. The customer will feel cold but will not benefit from cryotherapy. This doesn’t create a customer who purchases cryo packages or visits multiple times per week. Instead it compounds the problem: the person becomes convinced that cryo is a fad and could even become a harsh critic of cryotherapy, all while never truly experiencing cryotherapy.
