We typically ship within 24–48 hours after an order is placed. Within the continental USA, we ship via ground service (UPS or FedEx) from the Dallas–Fort Worth area.

The reservoir does not need to be completely filled—just enough oxygen to support a 15-minute EWOT session. However, to fill the reservoir completely, it typically takes:

• with a 10 LPM system
• with a 5 LPM system

We recommend using an outlet timer or smart outlet to automate the filling process at the same time each day.

Both systems are great and offer the full benefits of EWOT.

However, we do sell significantly more 10 LPM systems than 5 LPM systems. Here are the main reasons people choose the 10 LPM system:

• Multiple Users: The 10 LPM system allows a second person to use the system much sooner—often within 30–45 minutes if the machine is left running while the first person uses it. With the 5 LPM system, it can take closer to 1.5 hours, making it harder for multiple users to fit EWOT into their schedule.
• Flexibility: If someone wants to use the machine at different times of the day (e.g., normally at 7 AM but today at lunchtime), the faster fill time gives more flexibility in scheduling.
• Lifespan: The 10 LPM machine typically lasts longer because it runs half as long to fill the reservoir, reducing wear and tear over time.
• High Fitness Levels: Highly fit individuals sometimes need more than 1,000 liters of oxygen to complete a 15-minute session. These users can leave the machine running during their session and receive up to an additional 150 liters of oxygen with the 10 LPM system.

Our 10 LPM system is the most popular.

Most people who choose the 5 LPM system do so due to a tight budget, often related to significant health concerns.

You do not need to leave the oxygen concentrator running while using the EWOT system. Once the reservoir has enough oxygen for your workout, you can turn the concentrator off and breathe directly from the reservoir.

However, if someone plans to use the system shortly after you, you can leave the concentrator on so the reservoir stays fuller. You can also leave it on if you need more than 1,000 liters of oxygen to complete your workout.

We recommend you do an EWOT therapy session for 15 minutes to get full benefits. Depending on your health status, we recommend you work up to 70%–80% of your theoretical maximum heart rate. For your EWOT protocol, you can calculate your theoretical maximum heart rate as 220 minus your age.

However, for people with chronic illness, getting to 70%–80% of your maximum heart rate can take 6 months or longer. Even if you never get there, don't let the pursuit of perfection stand in the way of progress. Do only what you are comfortable with and listen to your body carefully. Even doing EWOT therapy while walking on a treadmill, bouncing on a rebounder, or standing on a vibration plate offers lots of health benefits.

For most folks, we recommend doing EWOT 3–5 times per week. We suggest starting EWOT therapy slowly and listening to your body. There are people doing as little as one session per week and others using it daily, all of whom are getting great results.

When it comes to EWOT vs. HBOT, they are very similar modalities that offer very similar benefits. However, because EWOT taps into the synergies of exercise, most folks report more dramatic results in a shorter period of time using EWOT versus HBOT. Additionally, EWOT is much cheaper, less time-intensive, and can be done safely in the comfort of your own home without the risks associated with hyperbaric chambers. You can read more about the similarities and differences here.

We don't recommend filling the night before. Our Exercise With Oxygen Training (EWOT) reservoirs are made to breathe. This means that if you fill it the night before, it will partially deflate overnight. This is designed to ensure that if moisture were to somehow get into the EWOT reservoir, it has a path to escape and does not create a condition conducive to mold.

Our EWOT reservoirs are much stronger than the pressure an oxygen concentrator can produce. For that reason, you will not damage your EWOT reservoir by continuing to run your concentrator.

We don't recommend running your concentrator for hours after the reservoir is full, as this causes unnecessary wear and tear on the concentrator. However, aside from the longer run time and wear on the device, you will not damage your EWOT system by running it while the reservoir is full.

Unused oxygen will be good to use for your next session. It does not need to be purged from the reservoir.

Our EWOT reservoirs are made of FDA-approved, BPA-free, virgin LDPE. This is the same material used for food products such as ketchup bottles, frozen food, and bread packaging. The FDA approves its use in the virgin state (meaning it has never been recycled) as it is chemically resistant, repels microorganisms, and doesn't leach harmful toxins when used to store food at a variety of temperatures. As any food packaging is constantly exposed to oxygen in the air, we have chosen this material for its safety in our application.

We do not use HEPA filtration. HEPA filtration will not make the oxygen you breathe any cleaner. A HEPA filter screens out dust and debris larger than 300,000 picometers in diameter (0.3 micrometers). All oxygen concentrators use a dust filter, simply to avoid dust getting into the gas separation equipment.

The gas separation equipment is designed to allow oxygen through (299 picometers in diameter) while blocking nitrogen (305 picometers) and argon (363 picometers). A 300,000 picometer particle will not make it through the gas separation equipment regardless of HEPA filtration.

The net result is that HEPA filtration does not make the oxygen you are breathing any "cleaner."

Altitude-switching EWOT systems are designed to create a low-oxygen delivery (lower than the air you breathe) to starve your body of oxygen for short bouts. The idea is that this causes your blood vessels to dilate and allow more oxygen in when you switch back to high-oxygen breathing.

However, the low-oxygen setting promotes increased inflammation, which is not helpful to most people. Those with chronic illnesses often tell us that altitude-switching made them feel dizzy and unwell. We don't believe in altitude switching for many people with chronic conditions, and you can read our position on our blog about altitude contrast EWOT.

For those who are interested in the effects of altitude switching and are well enough to seek any benefits it may offer, you can get the same benefits by simply holding your breath for 5–7 seconds at a time, a few times per EWOT session. Holding your breath allows 0% oxygen in and will dilate your blood vessels more effectively than altitude-switching technology.

Plus, it will save you thousands of dollars by not buying altitude-switching equipment—and spare you the hassle of flipping a mechanical switch while trying to maintain your exercise momentum and balance.

We catalog some of the growing research on EWOT on our Research Page. Beyond that, you can search the government research website, PubMed, for even more studies.

EWOT is referred to by many names, but exercise with oxygen therapy is often called “hyperoxic training”, with the word “hyperoxic” meaning “a state of excess supply of O₂ in tissues and organs.”

Our CatalystOne panel uses 8 wavelengths:

• 4 red wavelengths – 630nm, 650nm, 660nm, and 670nm
• 4 infrared wavelengths – 810nm, 830nm, 850nm, and 1060nm

Different wavelengths of red and infrared light penetrate tissues at different depths and can have varying effects, although many of the benefits overlap across wavelengths. We chose wavelengths that have a high volume of research supporting their positive effects on cellular biology and human health, ensuring the broadest, research-backed benefits for our customers.

Our dual-chip LEDs allow each LED to emit both a red light and an infrared light wavelength at the same time. This provides more even coverage of the treated area while also reducing the overall panel size.
