WHY CHOOSE AN INOGEN OXYGEN CONCENTRATOR?

There are a variety of options available to meet your supplemental oxygen needs, so why choose an Inogen Oxygen Concentrator rather than a competitor's product? Inogen products have been developed from the very beginning to improve the lives of those using oxygen therapy. Inspired by a beloved grandmother named Mae, Inogen was founded to create an oxygen solution that improved users' freedom, independence and mobility while helping them breathe better. Mae was convinced that there had to be a better option for oxygen therapy when she was diagnosed with COPD in the summer of 2000. After Inogen developed the very first Inogen One, Mae told us that it was better than anything she could have ever hoped for. We have continued to strive for that level of success year after year with innovative solutions for all of our oxygen users, and it continues to be our number one goal.

Our lightweight portable oxygen concentrator units are designed to help you live your life better on oxygen therapy. Even while receiving your supplemental oxygen, Inogen believes you should be able to continue to participate in your daily activities and do the things you love, all while getting the oxygen you need with our quiet oxygen concentrator units. There are other products from other companies that can provide you with supplemental oxygen therapy, but few are as lightweight, easy to use, portable and versatile as an Inogen oxygen concentrator.

CHOOSE INOGEN FOR OUR CHANGING WORLD

The way we interact now is changing almost every day because of the novel coronavirus pandemic. With those changes, we are learning to adjust our habits as well as the ways in which we move through the world. For people with breathing difficulties, this has been a nerve-wracking experience, and learning how to incorporate new protocols along with oxygen use can seem overwhelming. The great news is that with an Inogen oxygen concentrator, these adjustments are relatively easy.

Many states and cities now require wearing a cloth face covering when you are out in public. It is expected that these requirements will continue for some time, and are likely to continue for travel as well. If you use any of our Inogen One lightweight portable oxygen concentrator units, you can easily wear a cloth face covering right over the top of your nasal cannula without compromising the face covering or impacting your oxygen therapy at all. This means that you can follow government safety mandates, worry-free, and still get the oxygen you need no matter where you go. Additionally, each Inogen oxygen concentrator is easy to maintain and clean, which means that you can easily disinfect your portable oxygen concentrator and your nasal cannula and tubing every time you get home from a public place. This helps keep you, and everyone in your household, safe from potential infection.

We recognize that using your oxygen therapy while out in public during a pandemic is a new and unusual experience, and we want to make it as comfortable and as easy as possible for you. For more information about COVID-19 and Inogen oxygen concentrators, feel free to contact us any time.
