My Dad's Oxygen
Jeff, Thank you again for helping in getting the portable oxygen for my father’s needs. He absolutely LOVES the new equipment and the portability now, which has allowed him so much more freedom of activity! I appreciate your help, especially since it was a weekend. So grateful.

Absolutely one of the best companies
I've dealt with Jeff and his staff for a few years now and he is always a very professional type that truly cares about the customer and works toward getting the individual what is needed. He is a fair and honest person that knows his products.

Great experience!
Jeff is a blessing. I wasn't aware, after my purchase, that my needs were so different. I'm a neck breather. He went above and beyond to make sure my purchase was exactly as needed. HE took the initiative to contact my Dr to find out exactly what my needs were. With today's challenges, he nailed it. I WILL DEFINITELY recommend Jeff and his company for all your needs with oxygen. He's giving me independence again. He could have just concentrated on a sale. Nope, he wanted everything to be right,instead of just a sale.Jeff, you rock !! Thank you for all your help.

Extremely Satisfied!
Mr. Morris, My husband is extremely satisfied with 3 things. One, fast delivery, two your interest, three the machine itself…I am happy that we can finally enjoy dinner in a 1st class restaurant. Thank you!

Highly recommend!
Could not have had a more pleasurable experience with my purchase. They went above and beyond. Ask for Todd or Jeff for all of your oxygen needs and I promise you won’t go wrong. Would be from again 100 times out of 100!!

Great Company!
We had been looking at portable oxygen for my husband for quite some time. He had the small green canisters but wanted something lighter and more aesthetically pleasing. I came upon Inspired Oxygen and made an inquiry. Todd, the owner, called us that night and introduced himself, the company and the product. It seems like all we had to do was sign for the UPS delivery and take the product out of the box. Great company to handle your needs and I would recommend them without hesitation.

Can I use insurance to purchase a G4 unit from Inspired Portable Oxygen?

No. Typically, Insurance doesn’t purchase portable concentrators. Insurances may pay a rental fee for medical equipment and supplies only if a supplier has a Medicare or Medicaid supplier number. Inspired Portable Oxygen, the operator of this website, does not have a Medicare or Medicaid supplier number. Insurance will not pay for any medical equipment and supplies we sell to you.

Is financing available for the G4?

Yes, We do offer easy financing with approved credit. Please give us a call to discuss which package works best for you and we will help you get started on the simple financing application.

Will the Inogen G4 work for me?

Depending on your oxygen prescription, it’s likely that it will! The most common prescription for oxygen is 2-3 liters per minute, and the G4 can deliver that amount of oxygen using intelligent pulse dose delivery. The Inogen One G4 portable oxygen system is available by prescription only. If you have been prescribed oxygen, there is a good chance that the FIT System will work for you.

I'd like to get a loved one an Inogen G4. How do I do that?

If your loved one is on oxygen, there is a good chance Inogen will work for them! You can purchase a G4 or any other model to own and we will help you get the necessary doctor’s Rx.

My current oxygen equipment provider said they cannot assist me in getting a G4 portable. What should I do?

Because most oxygen equipment companies are dealing with Medicare and Insurance constraints, the G4 is not offered from most medical equipment companies. This is the main reason we are a discount retailer and why we assist so many oxygen users. You can purchase a new system from us, at a huge discount, and still keep your current oxygen equipment you may be getting through insurances.

How much does the Inogen One G4 cost?

Cost depends on which package you choose. You may want a system with one battery, or two. You may want to upgrade your warranty on the G4 device. We offer Exclusive G4 freedom/sale packages with discounts up to 60% off Inogen’s Suggested Retail Price.
