Who is this good for?
Anyone who wants more time away from an outlet — appointments, errands, church, family visits, and travel days.
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.
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.
