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.

Frequently Asked Questions

Do I need a prescription to buy the Rhythm TOC3?
Yes, a doctor's prescription is required to purchase this oxygen concentrator. This is a federal regulation in the United States and applies in many other countries as well. If you need help obtaining a prescription, our team can guide you through the process.
Can I take the TOC3 on an airplane?
Yes, the Rhythm TOC3 is FAA approved for use on commercial aircraft. The manufacturer has confirmed that it meets all applicable FAA requirements for carrying and using a portable oxygen concentrator on board. Be sure to notify your airline in advance, as most carriers require prior approval.
How long does the battery last, and how long does it take to recharge?
Battery life depends on your flow setting. On pulse dose setting 1, the battery lasts up to 6.6 hours. On continuous flow at 3 LPM, it lasts about 1.2 hours. A full recharge takes approximately 4.5 hours. You can also plug the unit into AC power for unlimited use at home.
Can I use my HSA or FSA to pay for this concentrator?
Yes, the Rhythm TOC3 is eligible for purchase with Health Savings Account (HSA) and Flexible Spending Account (FSA) funds. Contact our team if you have questions about reimbursement or need documentation to submit a claim.
What is the difference between continuous flow and pulse dose mode?
Continuous flow delivers a steady stream of oxygen at a set rate (up to 3 LPM), which is often used during sleep or rest. Pulse dose mode senses when you breathe in and delivers a measured burst of oxygen with each breath, which conserves battery life. Your doctor will prescribe the mode and setting that is right for you.

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.
