Top Tips to Buy a Portable Oxygen Concentrator (POC)

In recent years, Portable Oxygen Concentrators (POCs) have become essential for individuals with chronic respiratory conditions. Whether you're managing COPD, sleep apnea, or recovering from a respiratory illness, choosing the right POC can significantly improve your mobility and quality of life. 

Here are key tips to help you make an informed decision when buying a portable oxygen concentrator: 

1. Check the Oxygen Flow Type 

There are two types of oxygen delivery systems: 

  • Pulse Dose (on-demand): Releases oxygen only when you inhale. Lightweight and battery-efficient. 

  • Continuous Flow: Delivers a steady stream of oxygen regardless of breathing pattern. Ideal for those with higher oxygen needs. 

👉 Tip: Ensure the model you choose meets your doctor's prescribed flow requirements. 

2. Look for Battery Life and Power Options 

Battery life can vary from 2 to 10+ hours depending on the model and setting. Look for devices that: 

  • Offer extended battery packs 

  • Include AC and DC charging options (for home and car) 

👉 Tip: Frequent travelers should consider dual battery support for uninterrupted oxygen therapy. 

3. Weight and Portability 

Most POCs weigh between 2 kg to 5 kg. If you're buying for elderly users or plan to move around a lot, go for a lightweight model with a comfortable carry bag or trolley. 

👉 Tip: For maximum mobility, check if the device is FAA-approved for air travel. 

4. Noise Level Matters 

Some devices can be noisy, especially at higher settings. Look for models with noise levels under 40 decibels for quieter performance—ideal for night use or in public places. 

5. Maintenance and Warranty 

Choose a brand that offers: 

  • Minimal maintenance (no water refills or filters) 

  • Clear warranty terms (at least 1–2 years) 

  • Easy access to service centers and customer support 

👉 Tip: Always buy from authorized dealers or company-verified sellers to ensure product authenticity and support. 

6. Read Reviews and Compare Brands 

Popular brands like Oxymed, Philips Respironics, Inogen, and AirSep are known for their reliability. Read verified user reviews and compare: 

  • Features vs. price 

  • After-sales service 

  • Spare parts availability 

7. Consult Your Doctor First 

Before buying any oxygen concentrator, consult your pulmonologist or physician. They’ll recommend the right flow rate, type, and duration you need based on your health condition. 

Final Thoughts 

A portable oxygen concentrator is a valuable investment in your health and mobility. By keeping the above tips in mind, you can choose a device that fits your lifestyle, travel needs, and oxygen therapy requirements.
