Portable oxygen concentrators are prescribed by doctors to individuals who require supplemental oxygen, helping to treat conditions such as sleep apnea, asthma, emphysema, COPD, and other common respiratory diseases. By delivering oxygen-rich air, these devices regularly ensure that you’re receiving the prescribed oxygen levels you need to feel your best each day. Perhaps the biggest benefit of choosing a portable oxygen machine is that you can take it with you wherever you go, featuring lightweight and compact designs that are easy to transport. Our portable oxygen generators come equipped with several features – from auto-adjusting oxygen distribution to easy-to-read screens. Having access to portable oxygen when you need it most is a great way to continue enjoying the lifestyle you love!
