On-Demand, Reservoir, or Dual — how to choose

There are two ways to deliver high-flow oxygen during exercise. Both can meet the conditions described above: roughly 8–10 LPM, about 87–95% purity, a proper EWOT mask, and about 15 minutes of moderate exercise. Both are available in our Silver Value Line and our Gold Premium Line.

On-Demand EWOT

You turn on the concentrator, put on a specialized On-Demand mask, and start exercising. There is no bag to fill. The mask has a small reservoir attached that captures the oxygen that would otherwise be lost when you exhale, so you receive the concentrator’s output instead of losing half of it into the room.

Best when you want to start immediately, have limited space, or prefer a simpler setup with no large reservoir bag.

Reservoir EWOT

A 1000 litre bag is filled with oxygen from the concentrator before you exercise. You then breathe from that bag through a Reservoir-style mask. During the session you are breathing stored high-purity oxygen, not a mix with room air. A 10 LPM concentrator takes about 90–100 minutes to fill a 1000 L bag. That fill time is normal for any 10 litre-per-minute concentrator. Our reservoir bags hold the oxygen for up to a week, so you can prefill and use it when you are ready.

Best when you want the highest oxygen concentration during the session and you can plan the fill ahead of time.

Dual: On-Demand and Reservoir in one package

Some days you have time to fill the bag. Some days you want to start now. A Dual package includes the equipment for both methods, so you are not locked into one routine. Optimize is the only company that sells a true Dual system — On-Demand and Reservoir together — instead of forcing you to choose one style and give up the other. On this site, Dual is less than $150 more than the Reservoir package alone, in either the Silver or Gold line.

Neither method is a compromise. On-Demand is not “lesser EWOT.” Reservoir is not “inconvenient EWOT.” They are two delivery methods for the same high-flow exercise session. Choose the one that matches how you actually train — or choose Dual and keep both.

What every system still needs:

• A concentrator that can deliver 8–10 LPM at about 87–95% purity. A 5 LPM unit is for people breathing oxygen at rest, not for EWOT.

• The correct mask for that method. A hospital non-rebreather, nasal cannula, or aviator headset will dump oxygen into the room while you exhale.

• Stationary exercise: treadmill, bike, rebounder, or similar. Packages do not include the exercise equipment.

Gold or Silver is a separate choice. Gold is the premium concentrator, masks, tubing, and reservoir bag. Silver is the same On-Demand, Reservoir, or Dual setup with the value-line components. Pick the delivery method first, then pick Gold or Silver.
