Choose the Rove 6 if…
You need higher flow settings (5–6), the longest battery life for full days away from an outlet, or the higher oxygen output to stay active and on the go.
Your Questions, Answered
Do I need a prescription?
Yes — U.S. law requires one for portable oxygen concentrators. It's simple: after you order, email or fax your prescription, or we'll help retrieve it from your doctor's office. Your unit ships as soon as we have it.
Will Medicare or insurance cover it?
Most outright online purchases aren't covered, because coverage is usually tied to local rental programs. Buying privately gives you full ownership, no rental restrictions, and the freedom to travel — and flexible financing (Affirm, PayPal Credit, Shop Pay) keeps payments low. Some private plans also offer partial reimbursement; we'll tell you what to ask.
Are these brand-new and genuine?
Yes. We're a fully authorized Inogen dealer. Every unit is brand-new, factory-sealed, with authentic U.S. serial numbers and the full factory warranty. Unauthorized sellers risk used, refurbished, or counterfeit units with no protection — we never cut that corner.
What if I find it cheaper elsewhere?
We'll match it. We back every concentrator with a best-price guarantee on authorized pricing — and we have phone-only offers we can't post online, so it's always worth a quick call before you buy.
What if it isn't the right fit?
Our specialists match you to the right unit before you buy, so it's right the first time — and eligible, unopened items are backed by our customer-friendly return policy.
How fast will it ship, and is there support after?
In-stock units ship within 1–2 business days with free next-day options on select models, and tracking is emailed automatically. After the sale you're backed by U.S.-based specialists, a 3-year warranty (with optional extended and lifetime coverage), and our BBB A+ track record.
Is pulse dose enough, or do I need continuous flow?
Both the Rove 4 and Rove 6 deliver pulse-dose oxygen — released the moment you inhale — which works well for many daytime and active users. If your prescription calls for continuous flow (often for nighttime or higher demand), we carry continuous-flow units too. One call and we'll confirm what matches your prescription.
