Philips Respironics and Inogen are both respected and innovative medical device manufacturers. While their products are universally praised and well-engineered, you want to be sure that you pick the right portable oxygen concentrator for your needs, no matter the origin. Let’s examine some of the features from the top of the line models from these two great companies, the Respironics SimplyGo Mini and the Inogen One G4.
The SimplyGo Mini is less than 10 inches in all dimensions and under 6 pounds, making it both small in size and easy to carry for almost any patient. It provides oxygen via pulse flow in 5 setting options, maxing out at 1000 mL/minute. The concentrator also has a generous battery life of about 4.5 hours on a full charge. The unit itself is protected by a 3-year manufacturer’s warranty, except for the sieve beds which are guaranteed for 1 year. Also, the Mini features a rugged casing to resist scratches, impacts, and dings from everyday use. Additionally, the SimplyGo Mini is unobtrusive and quiet, operating at a very soft 43 decibels.
Amazingly, the Inogen One G4 portable oxygen concentrator is even smaller and lighter than the SimplyGo Mini, at less than 3 pounds and under 8 inches in all dimensions. The G4features Inogen’s Intelligent Delivery Technology that allows for automatic adjustment of the oxygen dose to best suit your breathing rate, whether you’re active or sleeping. The battery life is identical to the Mini’s, an average of 4.5 hours when fully charged. The G4 also comes with a 3-year manufacturer’s warranty but is slightly quieter. It operates at around 40 decibels of noise. Like all of Inogen’s portable oxygen concentrators, the G4 is FAA approved for passenger flight use.
Both of these portable oxygen concentrators stack up well next to each other. Although the G4 is smaller and lighter, it only offers 3 oxygen pulse dose settings versus the Mini’s 5. However, the G4 does provide Inogen’s auto-adjusting technology. They both can boast an excellent battery life and discreet, quiet operation. Also, both units are protected by excellent 3-year warranties from the manufacturers.
