How to Buy a Portable Oxygen Concentrator

If you or a loved one needs supplemental oxygen, a portable oxygen concentrator (POC) can provide life-changing mobility and freedom. But buying the right one isn’t just about picking the cheapest or lightest device — it's about matching your prescription, lifestyle, and long-term needs. In this guide, we’ll walk you through exactly how to buy a POC in a smart, safe, and cost-effective way.

1. Get a Proper Prescription First

Your starting point should be a consultation with your physician or pulmonologist. A prescription will clarify:

• Your required oxygen flow rate (e.g. pulse dose settings or liters per minute for continuous flow)

• How often and when you’ll use the POC (walking around, sleeping, traveling)

• Whether a lightweight or more powerful model is needed

Having a prescription ensures you purchase a medical-grade POC, which offers therapeutic oxygen levels — not just an oxygen “gadget.”

2. Understand the Key Features to Compare

When evaluating POCs, pay attention to these critical factors:

• Oxygen Delivery Type

  • Pulse-dose POCs deliver oxygen only when you inhale — good for most users and very battery efficient.

  • Continuous-flow POCs produce a steady stream of oxygen — important if your doctor prescribes a constant flow.

• Flow Settings & Output

  
  

  Make sure the POC supports the flow settings your prescription requires.

• Battery Life

  
  

  How long the battery lasts depends on your flow setting. Also check whether the manufacturer sells extended or external batteries.

• Weight & Portability

  
  

  Most POCs weigh between ~4–6 lbs.

• Noise Level

  
  

  Useful especially if you plan to use the device in quiet spaces or while sleeping.

• Travel / FAA Approval

  
  

  If you fly, you’ll want a POC that’s FAA-approved. Many airlines require you to carry enough battery for 150% of the flight duration.

• Warranty & Support

  • Confirm how many years the device is covered (look for 2–3+ years, depending on the brand).

  • Buy from authorized dealers to ensure you can get repairs or customer service later.

• Maintenance

  
  

  Regular filter cleaning or replacement is essential for performance.

• Legitimacy / Safety

  
  

  Be careful of ultra-cheap POC devices with no medical certification — some may not deliver real therapeutic oxygen.

3. Evaluate Cost and Insurance Options

• Typical Price Range: In the U.S., new POCs often cost $2,000–$6,000.

• Insurance & Medicare:

  • Many POCs are classified as durable medical equipment (DME), so part of the cost may be covered.

  • However, note: Medicare may not cover the full purchase — sometimes only rental is covered.

• Cost-Saving Tips:

  • Ask about seasonal promotions.

  • Consider financing or payment plans if available.

  • Because it’s a medical necessity, some POC costs may be tax-deductible — check with a tax advisor.

  
  

4. Avoid Unsafe or Fake Devices

• Only buy from trusted, authorized medical suppliers — not shady listings or unauthorized third-party sellers.

• Ensure the POC is FDA-cleared for medical use.

• Check for customer support, warranty, and service options. Devices without these are risky.

• Be wary of “too good to be true” offers: very cheap devices from unknown brands may not deliver therapeutic oxygen.

  
  

5. Think Long-Term Use vs Travel Needs

• If traveling by air is a priority:

  • Confirm the POC model is on the airline’s accepted list.

  • Make sure you have enough battery capacity to cover 150% of expected flight time, including layovers.

• If you're mostly using it at home or locally:

  • Battery life and weight are still important, but you might prioritize a model with more oxygen output (if needed) and good service support.

6. Try Before You Buy / Ask Questions

• Ask your supplier if you can demo a POC or test it for your typical usage (walking, sitting, etc.).

• Read user reviews and testimonials to learn about real-world battery performance, comfort, and durability.

• Confirm return policy and warranty details before committing.

7. Example Models to Consider

This is a list of some reputable POCs :

·        OxyGo Fit — Very lightweight (~3 lb), pulse-dose, great for high mobility.

·        Inogen Rove 6 — Durable, higher output, good travel performance.

• CAIRE Freestyle Comfort — Designed for long-term use, with good battery options.

• Rhythm Healthcare P2 Portable Oxygen Concentrator — Reliable design, solid brand.

Buying a portable oxygen concentrator is a meaningful investment in health and freedom. By starting with a prescription, understanding your oxygen needs, and carefully comparing models on factors like battery life, weight, and FAA approval, you can select a unit that truly fits your lifestyle. Always buy from authorized, reputable dealers, verify FDA clearance, and consider long-term costs like accessories, maintenance, and insurance coverage.

Choosing wisely means not just better mobility, but also safer and more reliable oxygen therapy. With the right POC, you can breathe easier and go farther — confidently.
