Is Vital Care USA an authorized retailer?

Yes — 100% authorized. Vital Care USA only partners with fully authorized U.S. manufacturers and distributors. Every unit includes the full factory warranty and authentic U.S. serial numbers. Your purchase is always protected.

Are the oxygen concentrators brand new?

Every concentrator we ship is brand new in original factory-sealed packaging unless clearly stated otherwise. All standard accessories, manuals, and warranties are included.

You can also review our easy, customer-friendly return policy if you have questions about unopened items or eligibility.

Do I need a prescription to order?

Yes — U.S. law requires a valid prescription for most home and portable oxygen concentrators. After checkout, your doctor can fax or email it to us, or you can upload it directly.

You can also email your prescription directly to us at support@vitalcareusa.com.

Once we receive it, your order ships right away.

Vital Care USA is not a medical provider and cannot provide medical advice. We do not determine oxygen flow settings or therapy levels. Always consult your licensed healthcare provider before selecting a unit or changing your prescribed oxygen settings.

Does insurance or Medicare cover this?

Most online oxygen concentrator purchases are not covered by Medicare or private insurance when bought outright. This is because coverage is usually tied to local in-network rental programs.

Many customers still choose to buy privately because it gives them:

  • Full ownership of their device
  • No rental restrictions
  • Freedom to travel, fly, or stay active without paperwork
When will my order ship?

Most in-stock oxygen concentrators ship within 1–2 business days after we receive your prescription and verify the order. Tracking is sent automatically by email.

We also offer next-day delivery options on select models and locations — contact us if you need fast delivery.

For full details on shipping methods, transit times, and signature requirements, please review our Shipping Policy .

Frequently Asked Questions

How much does it cost?
We work directly with O2 Concepts and trusted U.S. distributors and offer authorized, brand-new Oxlife LIBERTY2® 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. Oxlife LIBERTY2® 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 currently classifies portable oxygen concentrators like the Oxlife LIBERTY2® as “luxury” or “convenience” items, which means they typically 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 Oxlife LIBERTY2® because of its 24/7 continuous-flow capability, 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 Oxlife LIBERTY2® 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 Oxlife LIBERTY2® 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 does the Oxlife LIBERTY2® compare to other portable concentrators?
The Oxlife LIBERTY2® is unique because it combines true continuous flow with powerful pulse settings in a wearable design. Compared to many other portable concentrators, it offers:

- Continuous flow settings up to 2.0 LPM for 24/7 support
- Pulse dose settings 1–10 for active use and battery efficiency
- Compatibility with CPAP therapy as a wearable continuous-flow option
- Energy Smart Technology® for longer battery life and efficient power use
- DNA Technology® connectivity for advanced device monitoring and support

Many traditional continuous-flow portables are heavier, cart-based systems. The LIBERTY2® is designed to give you that same level of oxygen support in a more compact, wearable format.

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.

Protect Your Investment

Inside most concentrators there are sieve beds (also called columns) containing a mineral called zeolite, which is responsible for producing medical-grade oxygen. With normal use, these components are exposed to air, moisture, and environmental particles, which can affect performance over time.

Many patients also review or replace output and particle filters as part of ongoing device care to help maintain airflow and oxygen purity. Because usage and environments vary, service needs are addressed based on device performance rather than fixed schedules.
