Frequently Asked Questions

How much does it cost?

We work directly with O2 Concepts and authorized U.S. distributors to provide brand-new Oxlife INDEPENDENCE® units. Because of our partnerships and high order volume, our pricing is among the most competitive available from any official Oxlife dealer.

If you’ve seen a lower price elsewhere, it may be a refurbished, used, or imported unit listed as “new.” If you are comparing a genuine U.S. INDEPENDENCE® system, 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 typically does not allow patients to purchase portable oxygen concentrators like the Oxlife INDEPENDENCE® outright, even though the device meets the needs of most oxygen users.

Some private insurance plans may offer partial reimbursement after purchase with proper documentation. If you’d like help understanding what to ask your insurer, we can guide you through it.

Many customers still choose to own the INDEPENDENCE® because it offers 3.0 LPM of continuous flow, long battery life, and reliable 24/7 performance — making it a powerful alternative to tank deliveries and traditional rentals.

What financing options are available?

We offer flexible financing options to make owning a brand-new Oxlife INDEPENDENCE® simple and affordable.

Apply instantly through Shop Pay Installments, PayPal Credit, or Affirm — all with fast approvals and no paperwork required.

Financing makes it easy to enjoy continuous, reliable oxygen without waiting.

Where do I send my prescription?

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

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

How does the Oxlife INDEPENDENCE® compare to other portable oxygen concentrators?

The Oxlife INDEPENDENCE® is one of the most powerful portable concentrators available and is designed for patients who require higher oxygen levels or continuous flow. Compared to many POCs, it offers:

  • Continuous flow up to 3.0 LPM — far more than most portable units
  • Pulse flow settings up to 12 for active use and battery efficiency
  • Dual-battery system supporting long runtime and swap-while-running capability
  • Reliable 24/7 use as both a portable and stationary oxygen solution
  • Energy Smart Technology® for maximum oxygen output and long battery life
  • DNA Technology® for device connectivity, diagnostics, and support
  • CPAP and BiPAP compatibility for nighttime therapy
  • A durable, travel-ready case and design built for daily use

Most portable concentrators cannot reach these oxygen levels, making the INDEPENDENCE® a top choice for users who need higher flow rates and dependable 24/7 performance.

How do the LIBERTY2® and INDEPENDENCE® compare?

The Oxlife LIBERTY2® is a wearable, shoulder-carried concentrator with continuous flow up to 2.0 LPM and pulse settings 1–10 — great for active users and travel.

The Oxlife INDEPENDENCE® is a high-output rolling unit with continuous flow up to 3.0 LPM and 12 pulse settings, dual batteries, and 24/7 capability — ideal for higher oxygen needs or CPAP/BiPAP users.

In short: LIBERTY2® is lighter and more compact; INDEPENDENCE® delivers more power and runtime.

Which Oxlife model is right for me?

Choose the Oxlife LIBERTY2® if you want:

  • A wearable, compact concentrator
  • Continuous flow up to 2.0 LPM
  • Lightweight daily and travel use

Choose the Oxlife INDEPENDENCE® if you need:

  • Higher oxygen levels (up to 3.0 LPM continuous)
  • 24/7 portable + home use in one device
  • CPAP/BiPAP support and long dual-battery runtime

If you’re unsure, our team can review your prescription and help you decide.

Kenneth Keim
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.
