The Inogen at Home model is the only continuous flow and at-home model Inogen offers. It has a noise level (45 decibels) that is similar to other continuous flow portable oxygen concentrators we’ve researched. This model is different than the other Inogen models in that it runs on electricity, so there is no charging time or battery life to consider. It uses about 100 watts of energy, which is approximately the same as a standard 100-watt lightbulb (standard lightbulbs used in the home). If you need a continuous flow oxygen concentrator and spend most of your time at home, the Inogen at Home model could be a perfect fit for you.
