Portable Oxygen Concentrator Buying Guide for U.S. Users
Portable oxygen concentrators (POCs) have become an essential tool for Americans living with respiratory conditions like COPD, pulmonary fibrosis, or chronic heart failure. But with dozens of models and strict airline rules, how do you choose the right one?
This guide answers the most common questions U.S. users have about POCs.
✅ What Is a Portable Oxygen Concentrator?
A portable oxygen concentrator is a compact medical device that pulls in ambient air, removes nitrogen, and delivers concentrated oxygen to the user. Unlike oxygen tanks, POCs:
• Weigh less (typically 4–6 lbs)
• Run on rechargeable batteries
• Are approved for daytime and travel use
• Are FDA-regulated and require a doctor’s prescription
📌 Note: Always choose a unit that’s FDA-cleared and backed by clinical-grade performance.
✈️ Can You Fly with a POC in the U.S.?
Yes, but only FAA-approved models are allowed onboard. Examples include the Inogen One series, Philips SimplyGo, and SeQual Eclipse.
Here’s what you need:
• FAA-compliant device (check label or specs)
• Enough battery power for 150% of total flight time
• Advance notification to the airline
• Medical clearance form if required by the carrier
TSA allows medical devices as carry-ons with no extra fees.
✅ Pro Tip: Pack your device in a carry-on bag with spare batteries and a charging cord.
🔄 Pulse Flow vs. Continuous Flow: What’s the Difference?
Choosing the right oxygen delivery mode is crucial.
| Feature | Pulse Flow | Continuous Flow |
|---|---|---|
| Oxygen Delivery | On inhalation only (saves power) | Steady stream regardless of breath |
| Battery Life | Longer (4–9 hours) | Shorter (2–4 hours) |
| Use Case | Daily activity, light mobility | Nighttime, higher O₂ demand |
| Device Size | More compact | Typically heavier or stationary |
👩⚕️ Consult your physician to determine which flow type suits your oxygen needs.
🧳 Portability, Weight, and Battery Life
Most portable concentrators weigh 4.5–6 lbs, small enough to carry or wear in a shoulder/backpack case.
Battery duration varies:
• Standard battery: 2–4 hours
• Extended battery: up to 9 hours
• Car and AC chargers available for on-the-go use
Look for models with quiet operation (below 45 dB) if you’re using them in public or during sleep.
⚠️ Prescription Requirements & Device Safety
All medical-grade POCs require a valid prescription in the U.S.
Be cautious of devices sold online without prescription—many are:
• Not FDA-approved
• Ineffective at delivering therapeutic oxygen levels
• Potential safety risks
✅ Always check the oxygen concentration (should be ≥90%) and ensure the supplier is certified.
💵 How Much Does a POC Cost in the U.S.?
| Type | Average Price (USD) |
|---|---|
| New Portable Unit | $2,000 – $4,000 |
| Refurbished / Used Unit | $1,000 – $2,500 |
| Weekly Rental (avg.) | $120 – $180 |
Optional accessories (spare battery, travel cart, case) may cost $200–$500+.

🏥 Will Medicare or Insurance Cover My Device?
Yes—under certain conditions.
Medicare Part B: Covers as Durable Medical Equipment (DME) if prescribed
Medicare Advantage: May cover broader range—check with provider
Private Insurance: Usually requires prior authorization
In most cases, insurance plans rent the equipment monthly, rather than paying for it in full.
📍 Use your ZIP code to check eligibility with local DME providers.
🧼 Maintenance, Safety, and Daily Use
Keeping your POC clean and safe is key to long-term use.
Maintenance tips:
• Clean or replace filters weekly
• Wipe exterior with a dry cloth (no water or aerosols)
• Store batteries in a cool, dry place
• Keep device away from heat, fire, or direct sunlight
❓ Frequently Asked Questions
Q1: Can I sleep with a portable oxygen concentrator?
✅ Yes—if your doctor prescribes nighttime use and the device provides continuous flow.
Q2: How loud are these machines?
📉 Most are under 45 decibels, similar to a quiet office or soft fan.
Q3: Can I test before buying?
🔄 Many suppliers offer weekly rental programs or 30-day returns on new units.
✅ Ready to Find the Right Oxygen Concentrator?
Choosing the right POC improves your freedom, health, and comfort. Whether traveling or staying active at home, an FDA-approved, prescription-ready unit can make all the difference.
