DeVilbiss iGo2 Portable Oxygen Concentrator — Full Review
Published 2026-07-21
Most portable concentrators in this price range are pulse-dose only. The DeVilbiss iGo2's ability to also deliver continuous flow at rest is what sets it apart — it means one unit can potentially cover both daytime pulse-dose activity and overnight continuous-flow needs, depending on your prescription.
Why continuous flow matters
Continuous flow delivers a steady stream of oxygen regardless of breathing pattern, which some patients need overnight or during sleep when breathing becomes shallower and less regular — a pattern that can under-trigger pulse-dose sensors on other devices.
Trade-offs
Units that support continuous flow tend to be a little heavier and drain the battery faster in that mode than pure pulse-dose devices, so expect shorter runtime per charge when running continuous flow versus pulse-dose.
Bottom line
If your prescription includes continuous flow at any point in the day, the iGo2 is worth a look precisely because it avoids owning two separate machines. Talk to your treating physician about your specific flow requirements before choosing a mode-flexible unit like this one — our team can walk through the spec sheet with you on a call.
