What is Exercise with Oxygen Therapy (EWOT)?

Exercise with Oxygen Therapy is the practice of breathing higher concentrations of oxygen while exercising. This approach is also known as Oxygen Enhanced Exercise. EWOT is a wellness practice, not a medical treatment.

Turbo Oxygen EWOT System in a Nutshell

The Turbo Oxygen EWOT System comprises:

  • Oxygen Machine, which takes oxygen from the ambient air, concentrates it, and feeds it to the reservoir bag.
  • Oxygen Reservoir Bag, which stores oxygen and makes it available for the user during EWOT.
  • Dual-inlet Turbo Mega-Flow Mask, our patented mask (US Patent 11,305,079), which is connected to the Reservoir Bag through two connector hoses.

Selecting the Right Turbo Oxygen (EWOT) System

The Turbo Oxygen System is available in many variants. The best EWOT system for you depends on how many people will use it, how long your sessions are, the space you have and your budget. Let's have a look at the factors that will help you choose the right Turbo Oxygen System for you.

1. Oxygen Flow Rate

Flow rate is the amount of oxygen delivered by the Oxygen Machine in a minute. So, a 10 LPM machine delivers 10 liters of oxygen per minute, while a 5 LPM machine delivers 5 liters per minute.

The main difference between the 10 LPM and 5 LPM systems lies in the filling time. A 10 LPM machine fills the Oxygen Reservoir Bag faster than a 5 LPM machine.

A 10 LPM System is ideal for:

  • Multiple users doing EWOT sessions, as it reduces waiting time between sessions
  • Faster bag fill time
  • Users who want to go beyond 15-minute sessions. In this case, you can run the 10 LPM oxygen machine while exercising, adding 10 liters of oxygen per minute to the bag.

A 5 LPM System is a good option if:

  • You are comfortable with a slower bag fill time
  • You want a more budget-friendly setup

2. Reservoir Bag Size

We offer two variants of the Oxygen Reservoir Bag: the 900 Liter Bag and the 500 Liter Bag. As the name suggests, a 900-liter bag stores 900 liters of oxygen and a 500-liter bag stores 500 liters of oxygen.

900L Bag

  • One full bag lasts 15 minutes or more of EWOT
  • Ideal for full-length sessions without interruption
  • Great if you prefer longer workouts or higher breathing intensity
  • Bag size when fully inflated: 8 ft (H) x 3.5 ft (W) x 3.5 ft (D)
  • Filling time: about 90 minutes with a 10 LPM machine, about 3 hours with a 5 LPM machine

500L Bag

  • One full bag lasts about 8–10 minutes of EWOT
  • Good option if space is limited or if you prefer two shorter EWOT sessions a day (for example, two sessions of 7–8 minutes)
  • Bag size when fully inflated: 5 ft (H) x 3.5 ft (W) x 3 ft (D)
  • Filling time: about 50 minutes with a 10 LPM machine, about 100 minutes with a 5 LPM machine

Note: the filling times above are based on the machine running at its maximum flow rate. How long a full bag lasts depends on your breathing rate, lung capacity and how vigorously you exercise. The session times above are for vigorous exercise; at a lower intensity, a full bag may last longer. For more detail, see our reservoir bag guide.

Choosing The Right Oxygen Concentrator

10 LPM Machine

  • Suitable for longer EWOT sessions or multiple users sharing the system
  • Faster refill time with less waiting

5 LPM Machine

  • Budget-friendly option
  • Good option if you're comfortable with a slower fill time and longer wait time

Already have a stationary oxygen concentrator? You only need a reservoir bag kit. Our bag kits work with any stationary oxygen concentrator; a continuous-flow concentrator of 5–10 LPM is ideal.

Choosing The Right Reservoir Bag

900 Liter Bag

  • Best for longer sessions or multiple users sharing the system
  • Requires fewer refills

500 Liter Bag

  • Best if you plan to do shorter EWOT sessions
  • Good option for saving space

Choosing The Right Mask

  • Small- Suitable for persons who are 5’3” or below
  • Medium- Suitable for users 5'4" to 5'11"
  • Large- Suitable for users 6'0" and above

How Often Should I Do EWOT?

We recommend EWOT sessions of about 15 minutes, 3–5 times per week. If you're new to EWOT, start with shorter sessions of 8–10 minutes and build up gradually. Responses vary from person to person and depend on your overall health, fitness level and exercise routine, so set realistic expectations and stay consistent.

Why is the Turbo Oxygen System Affordable?

Our goal is to make EWOT more accessible for individuals from all walks of life. That's why we offer two system levels, 5 and 10 LPM machines, and bag kits for people who already own a concentrator, so you only pay for what you need.

If you use oxygen for a medical condition, talk to your doctor before trying EWOT. EWOT is not a medical treatment. Keep your EWOT setup away from smoking, open flames and heat sources.
