5 Liter Portable iGo 2 Oxygen Concentrator

Our new 5 Liter Portable iGo 2 Oxygen Concentrator made by Devilbiss is the ultimate take-it-with-you solution for oxygen anywhere you need it. At just 4.85 lbs (2.2 kg) and measuring a compact 8.4" × 3.5" × 8.6", it slips easily into its included over-the-shoulder carry case and fits perfectly in tight spaces at home, in the car, or at the gym. If you want true portability without sacrificing performance, this is the one.

It’s great for EWOT using the reservoir bag method — a convenient, on-the-go way to add oxygen to your workouts. Like our stationary 5-liter model, it is not designed for on-demand high-flow EWOT (which studies such as those by von Ardenne show requires at least 8 LPM), but it delivers reliable pulses of 90%+ pure oxygen that work very well with a reservoir bag. You can run it in SmartDose™ mode (which automatically adjusts to your breathing) or switch to manual mode — a key feature many of our EWOT customers prefer for consistent delivery during training.The same compact unit is also excellent for ozone applications. It serves as a reliable oxygen feed source for making ozonated water and ozonated glycerin at home or in small travel setups. It comes with two rechargeable batteries for extended run time, whisper-quiet operation (<37 dBA), rugged overmold protection, and FAA-compliant design — everything you need for real everyday portability and convenience.
