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!

James New England

“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!”

Cheryl Florida

“Courtney was very helpful. She answered all my questions! Infact, after receiving my Inogen 5 I have a few more questions which I'm sure Courtney will answer for me. It came quickly. Courtney had it sent out for the next day at 10:30 am. I am very happy with my Inogen 5. I feel I can go places now without worry I am going to run out of oxygen!”

John Washington

“This has been the best online buying experience I have ever done, Leo has been more than helpful, unlike other places when I was shopping around and reading reviews Main clinic supply answered the phone right away every time, my package said overnight before 10:30AM, it was here at 10:15AM the next day! Can't say enough good things, they realize you need your oxygen now they get it to you fast!”

Howard Virginia

“Mr. Kyle Sill was wonderful. Patiently explained all the options, answered all my questions helpfully and knowledgeably, and with his help, I was able to buy the perfect concentrator to meet my needs. Unfailingly polite, respectful, personable. My experience with Main Clinic Supply was pleasant and satisfying in all respects, and I would recommend them to anyone.”

Tim Indiana

“We just purchased our 2nd Inogen portable O2 unit from Main Clinic Supply. The staff was very professional and shipping/receipt was very timely. We sent the old unit in for service and to have as an emergency backup and it was sent back the next day and in good working order. Great service!”

Russell California

“This is the second Inogen oxygen concentrator that I have purchased from Ricky Gardea with the lifetime warranties. He is very knowledgeable and professional. I have another Inogen floor model that I purchased from Inogen direct but Ricky is much better, at least for me. The service that I have received at Main Clinic Supply and its delivery process (FedEx) is outstanding. I can speak with over 12 years experience in purchasing and using oxygen concentrators.”

Joyce North Carolina

“I really needed this portable oxygen system for the longest time. I finally made up my mind to get one even though they are expensive. I suffer from Asthma/Chronic obstructive pulmonary disease. I was always stuck in the house on my oxygen 24/7 and could not go anywhere or do anything. Your representative, Dylan, was excellent and very knowledgeable and because of his expertise, I was sold. So glad, Dylan helped me out regarding my new "freedom".”

Stephanie Missouri

“Thank you Main Clinic Supply for exemplary customer service, excellent communication, and expeditious shipping of the InogenOne G5 Oxygen Concentrator! My dad is elated with the product!!”
