Frequently Asked Questions

How much does it cost?

We work directly with Inogen and offer authorized, brand-new units. Because of our direct partnership and high order volume, our pricing is among the most competitive available from any official Inogen dealer.

If you’ve seen a lower price elsewhere, it may be a refurbished or imported unit listed as “new.” If you are comparing a genuine U.S. Inogen product, we’re happy to review it and match or beat it whenever possible. Our goal is simple: make life-changing oxygen therapy accessible and affordable — never confusing or stressful.

Does Medicare cover this?

Medicare currently classifies portable oxygen concentrators like the Inogen systems as “luxury” or “convenience” items, which means they do not approve them for direct purchase.

Some private insurance plans do offer partial reimbursement after purchase when proper documentation is submitted. If you would like help determining whether your plan offers this, we can guide you through what to ask your insurer.

Even without Medicare coverage, many customers choose to own an Inogen because of its reliability, mobility, and long-term cost savings compared to rentals.

What financing options are available?

We offer flexible financing options to give you affordable access to a brand-new Inogen unit with low monthly payments.

You can apply instantly through Shop Pay Installments, PayPal Credit, or Affirm, all with fast approvals and no paperwork.

Financing makes it easy to enjoy the freedom of portable oxygen without waiting.

Where do I send my prescription?

If your model requires a prescription, you can email it to us at support@vitalcareusa.com.

If you don’t have a copy on hand, we can also contact your doctor’s office and help retrieve it after your order is placed.

How do the Inogen Rove 6 and G5 differ?

The Inogen Rove 6 is the newest generation, offering upgrades in durability, usability, and power compared to the G5. Improvements include:

  • A redesigned contoured carry handle
  • A more intuitive control panel
  • Stronger durability and improved reliability
  • Smoother pulse delivery at higher settings
  • A refreshed design and upgraded user interface

Both systems are excellent — the Rove 6 simply adds refinements that make everyday use easier and more comfortable.

Inogen® Rove 6 Portable Oxygen Concentrator
Love my new Rove 6

Love my new Rove 6. Gives me twice the amount of time than my Rove 4. Very satisfied.

Eleanor H.
Vital Care USA
Great for everyday use

I’ve been using my Rove 6 daily for six months now and it still feels brand-new. I take it grocery shopping, to church, and even on short flights. It’s light, quiet and gives me a sense of freedom I haven’t had in years.

Roger D.
Vital Care USA
Perfect for musicals

We took our Rove 6 to a theater show last week and it ran quietly throughout the performance. Small enough to keep at our feet.

Pat L.
Vital Care USA
Better than expected

The unit charges faster than advertised and feels solid. I can see why Vital Care gets such good reviews.

Thomas A.
Vital Care USA
Reliable through travel

I flew to Denver with the Rove 4 and it never skipped a beat. Even at altitude it delivered steady oxygen flow.

George T.
Vital Care USA
Made our Europe trip possible

We toured Spain for two weeks and the Rove 6 handled train rides and flights perfectly. Local outlets worked fine with our converter.

Gerald M.
Vital Care USA
Excellent long-term performance

We’ve had our Rove 4 for almost a year now and it’s still running like the day it arrived. My husband uses it for daily walks around the neighborhood and recharges it every night. Filters are easy to replace, and Vital Care always ships extras fast.

Patricia J.
Vital Care USA
Incredible machine

Took the Rove 6 to our daughter’s wedding in Hawaii and it kept me comfortable through the entire day. Battery swaps were quick and easy.

Thomas P.
Vital Care USA
Perfect for concerts and dinners

I took my Rove 6 to a musical downtown and it handled the entire show on a single charge. It’s a bit audible in silence but totally fine in public venues.

Howard G.
Vital Care USA
Travelled through Europe flawlessly

Used the Rove 6 across Italy and France for two weeks. Airline staff were very familiar with it and we never had trouble charging.

James P.
Vital Care USA
Couldn’t be happier

This concentrator has restored my confidence to travel and socialize again.

Joanne P.
Vital Care USA
Exceptional comfort

I forget I’m even using it most of the time. The airflow feels natural and smooth.

Helen M.
Vital Care USA
Feels reliable

After months of use I can say this concentrator has zero surprises—no odd alarms, no battery issues. It simply does its job.
