Portable oxygen concentrators at American Oxygen
A portable oxygen concentrator (POC) is a lightweight, FDA-cleared device that pulls oxygen from the air so you can move freely — no tanks. Most are pulse dose (they deliver oxygen when you breathe in); a few offer continuous flow for higher or overnight needs. Your prescription sets the flow — we help you match the model.

Your prescription comes first — then it's about weight, oxygen output and how you live.
| Choose this if… | Our pick | Why |
|---|---|---|
| You want the best all-around value | OxyGo NEXT — $1,995 | Inogen-built platform, 6 settings, up to 13h, 5-yr warranty. |
| You're on a tight budget | Rhythm P2-S3 — $995 | Lightest Rhythm, FAA-approved, 3 settings. |
| You want the lightest possible unit | Inogen Rove 4 (2.9 lb) / OxyGo FIT+ | Ultralight for all-day carry and travel. |
| You need higher output (settings 5–6) | OxyGo NEXT · Rhythm P2-E6/E7 · Rove 6 | More oxygen per breath for higher pulse settings. |
| You need continuous flow (higher/overnight) | Philips SimplyGo (CPO) | Steady stream for prescriptions a pulse unit can't meet — talk to us first. |
| You want a premium unit for less | CPO OxyGo NEXT — $1,295 | The star platform at a Certified Pre-Owned price, warranty by AO. |
We help you choose the right unit — not the most expensive one. Buying guidance, not medical advice; your prescription sets the flow.
Pulse dose vs. continuous flow
Light, mobile, most common
Conserves oxygen, so units run 3–5 lb and last hours per charge. Great for daytime mobility, travel and errands.
- Settings shown as levels (1–6)
- Best for staying active & flying
- Most of our models are pulse dose
Steady stream, higher output
Delivers a constant liters-per-minute flow like a home unit. Heavier, but needed for continuous or higher-flow prescriptions.
- Best for higher-flow / overnight needs
- Transportable rather than ultralight
- See the Philips SimplyGo (continuous) and Rhythm TOC3
Flying with a portable oxygen concentrator (FAA rules)
Every new portable we sell is FAA-approved.
U.S. airlines with 19+ seats must allow it onboard under the Air Carrier Access Act — with advance notice and enough battery. A few things to plan:
- 150% battery rule: bring batteries for 1.5× your total travel time
- Notify your airline 48–72 hours ahead
- Carry your prescription / physician's letter
- Fully charge before departure
- TSA allows POCs through security & onboard
- We'll build the right battery kit for your trip
Airline policies vary — confirm with your carrier. See FAA and TSA guidance for official rules.

Portable oxygen concentrators — frequently asked questions
Do I need a prescription to buy a portable oxygen concentrator?
Yes. POCs are FDA-cleared medical devices and require a valid prescription — even when you pay cash. Send us your doctor's script and we make the rest easy. Accessories like cannulas, filters and batteries are sold without a prescription.
Are your portable oxygen concentrators FAA-approved for flying?
Every new portable we sell carries FAA-compliant labeling for U.S. air travel. Bring batteries for 150% of your travel time and notify your airline 48–72 hours ahead. Always confirm with your carrier.
What's the difference between pulse dose and continuous flow?
Pulse dose delivers oxygen when you inhale (lighter, longer battery — most portables). Continuous flow delivers a steady stream (needed for some higher or overnight prescriptions, e.g., Philips SimplyGo). Your prescription decides.
Which portable oxygen concentrator is best for travel?
For most travelers, the OxyGo NEXT (up to 13h, 6 settings) or Inogen Rove 6. Want the lightest? Inogen Rove 4 (2.9 lb) or OxyGo FIT+. On a budget? Rhythm P2-S3 ($995).
How much does a portable oxygen concentrator cost?
New units run $995–$3,399; Certified Pre-Owned and Open Box start around $1,100. Pay monthly with Affirm.
Can I buy a portable oxygen concentrator without insurance?
Yes — we're a cash-pay retailer, so you can buy outright or finance with Affirm, no insurance required (prescription still needed). Medicare generally covers rentals, not purchases.
Is a Certified Pre-Owned or Open Box concentrator safe?
Yes. Each is inspected, function-tested, sieve-column and battery-checked, cleaned, and backed by warranty by American Oxygen. Condition is disclosed per unit.
Is the OxyGo NEXT the same as an Inogen?
It's built by Inogen on the same platform as the One G5 / Rove 6, at a lower price. We're an authorized OxyGo dealer. This is a product comparison — we are not an authorized Inogen dealer.
How long do batteries and sieve columns last?
Batteries are user-replaceable; sieve columns (the unit's 'lungs') are typically replaced about once a year. We stock both.
Can I use a portable oxygen concentrator while sleeping?
Only if your prescription and delivery type allow it — some patients need continuous flow overnight. Share your Rx and we'll tell you honestly which units fit. (We don't give medical advice.)
Which portable is lightest for travel?
The lightest units are the Inogen Rove 4 (2.9 lb) and OxyGo FIT+; the Rhythm P2-S3 (3.3 lb) is the lightest budget option. Filter by Lightest above.
Do you ship nationwide and offer local pickup in Miami?
Yes — free U.S. shipping over $99, shipped from Doral, FL, plus local pickup and an in-person showroom serving Miami and South Florida.
Not sure which one is right for you?
Send us your prescription or just tell us how you'll use it — travel, daily errands or overnight — and our Doral team will match you to the right concentrator and battery kit. English & Spanish.
