Discover the Benefits of our Portable Oxygen Concentrators

Have you been prescribed supplemental oxygen therapy for a respiratory condition? Do you need a personal portable oxygen concentrator for the freedom to travel, leave the house, and enjoy life? A portable oxygen concentrator (POC) allows you to continue your daily routine and travel plan with minimal inconvenience. Have a look at what our portable oxygen concentrators can do for you.

The Freedom Of A POC - Portable Oxygen Concentrator

You do not have to put life on hold or sit on the sidelines when you have a POC (portable oxygen concentrator). They are designed for maximum mobility, allowing you to stay active and independent. It goes where you go, works where you work, and even travels when you need a vacation. A portable oxygen concentrator is the ultimate convenience for people with breathing difficulties.

Our Inogen concentrators are even FAA-approved, ensuring you can take your concentrator on flights!

Ultra Quiet Operations and State-Of-The-Art Technology

One of the things that bothered people with older oxygen machines was their noise. The machines disturbed their peace at night and the people in their household. We have the quietest oxygen concentrators on the market.

Our concentrators use cutting-edge technology that has consistent and reliable oxygen delivery, adapting to your breathing patterns for optimal support. Then, with extended battery options, you can enjoy up to 10 hours of uninterrupted oxygen, reducing the need for frequent charges.

We Have Thousands Of Happy Reviews!

“The Portable Oxygen Specialist was extremely knowledgeable and patient. He answered all of my questions and was not pushy. He also kept me posted of shipping and delivery dates. It was delivered via FedEx the next day! He also offered to help setup the machine. However, the instructions with photographs were extremely easy to follow to setup even for my father who is elderly and has limited vision. My father loves the machine!”
