The difference between the Economy and Premium systems comes down to the oxygen machine and the warranty included. The Premium system features a Devilbiss oxygen machine made in the USA and comes with a 3-year warranty on the machine, bag, and mask. It is designed for higher durability. The Premium Oxygen Machine delivers oxygen more efficiently at a higher 20 PSI output pressure. The Economy system uses the O2E2 oxygen machine (12.5 PSI output pressure) and includes a 1-year warranty, making it a more affordable option while still providing the same EWOT functionality.

The EWOT System typically arrives in 3 separate packages: the Oxygen Machine, Bag System, and Bag Stand. These packages may arrive on different dates and through different shipping carriers, so there’s no need to worry if one package arrives before the others. In most cases, the Oxygen Machine ships via FedEx, while the Bag System and Bag Stand are usually shipped through UPS or USPS.

Yes, you can leave the oxygen reservoir bag filled between sessions. You do not need to empty the bag after each use. A small amount of air may slowly escape through the pressure relief valve, which is completely normal. Just make sure the valve is turned counterclockwise, and the blue cap remains securely in place.

You’ll need approximately 25 sq. ft. of space for the reservoir bag setup, along with additional room for the oxygen concentrator and your preferred exercise equipment, such as a bike, treadmill, or elliptical. For proper airflow, the oxygen concentrator should have 1–2 feet of clearance on all sides, and the reservoir bag should be placed at least 1-2 feet away from the wall.

All of our oxygen concentrators produce sound levels below 50 dB, which is roughly equivalent to the noise level of a quiet conversation or a household refrigerator. Most users find the sound level comfortable for home use.

Filling times vary depending on the size of the reservoir bag and the flow rate of the oxygen machine. The following estimates are based on the oxygen machine running at its maximum flow rate. 

900 Liter Reservoir Bag

• With a 10 LPM Oxygen Machine: approximately 1.5 hours
• With a 5 LPM Oxygen Machine: approximately 3 hours

500 Liter Reservoir Bag

• With a 10 LPM Oxygen Machine: approximately 1 hour
• With a 5 LPM Oxygen Machine: approximately 1.5 hours

LPM stands for litres per minute — the rate at which the oxygen concentrator produces oxygen. The higher the LPM, the faster your reservoir bag fills. A 10 LPM machine fills your bag in approximately half the time of a 5 LPM machine, is built for more frequent and demanding use, and offers greater long-term durability. The 5 LPM is the budget-friendly option and perfectly capable for individual home use when you have flexibility in your schedule to allow longer bag fill times. If your sessions are frequent, or you want the shortest possible wait between sessions, the 10 LPM is the better investment.

Yes. EWOT is designed for regular, consistent use. Most users complete a 15–20 minute session daily or several times a week. The concentrator is built for reliable home use and performs consistently with regular sessions. Daily use is not only safe — it is how you get the most out of your EWOT practice.

Any exercise that gets your body moving works well with EWOT. You can use cardio equipment — a treadmill, exercise bike, cross trainer, or rower — or do bodyweight and resistance exercises such as push-ups or bench press. The key is to keep moving throughout your session so your body is actively consuming the oxygen being delivered. The type of exercise matters less than consistency and effort level. Start at a comfortable pace and build intensity as your practice develops.

The oxygen reservoir bag requires no cleaning. For the mask: soak it in a 3% hydrogen peroxide solution for 5–10 minutes, ensuring all surfaces are fully covered. Rinse thoroughly with clean water to remove any residue, then allow the mask to air dry completely before use. For the oxygen concentrator: clean the reusable cabinet air filter at least once or twice a week to maintain optimal performance and airflow. Regular filter cleaning extends the life of your concentrator and ensures consistent oxygen output.

When done correctly, EWOT is a safe and effective wellness practice that can help you reach your fitness and wellness goals. We recommend speaking with your doctor before starting EWOT, particularly if you have existing health conditions, to confirm it fits safely into your routine. Your physician can help you determine the right session length and intensity for your individual situation.
