Respironics SimplyGo Mini vs. Inogen One G3

When comparing two different portable oxygen concentrators, there are a variety of factors you need to consider. Are they truly portable? Are they light? Small? How is the battery life? What about a warranty? The factors can easily seem endless. Use this guide to help you as you explore your options and make your choice between two excellent portable oxygen concentrators, the SimplyGo Mini and the Inogen One G3.

The SimplyGo Mini is both compact and lightweight at less than 10 inches in all dimensions and under 6 pounds. It can provide pulse flow oxygen up-to 5 settings and up to a maximum of 1000 mL/minute. The unit’s battery life is above average at 4.5 hours, enough for most activities. The unit is covered by a 3 year manufacturer’s warranty, except for the sieve beds which are guaranteed for 1 year. Also, the Mini is equipped with a reinforced casing to stand up to the bumps, bangs, and dings that accompany an active lifestyle. The unit is quiet during operation, only generating a soft 43 decibels of noise.

The Inogen One G3 portable oxygen concentrator is comparable in size and weight to the SimplyGo Mini, at about 6 pounds and under 9 inches in all dimensions. While it also delivers oxygen via pulse dose at a choice of 5 settings, the G3 boasts Inogen’s custom technology that automatically adjusts the oxygen dose to best complement your current breathing rate. The battery life differs just slightly from the Mini, with an average of 3 hours of operation on a full charge. Like the Mini, the G3 carries a 3 year manufacturer’s warranty and produces only 39 decibels of noise. The G3 is also FAA approved for passenger flight use.

Respironics SimplyGo Mini vs. Inogen One G3 Portable Oxygen Concentrator

To conclude, you can see that these are both great portable oxygen concentrators. Most of their features are nearly identical, but the SimplyGo Mini does enjoy an additional 90 minutes of average battery life. However, the Inogen One G3 features auto-adjusting technology to maximize the efficiency of your oxygen delivery, which can certainly be a useful feature for some patients.
