🧭 How to Choose the Right Portable Oxygen Concentrator

Here are a few key factors to consider:

• Battery Life: Look for extended battery options if you're active or traveling.
• Weight: Anything under 5 lbs is easy to carry regularly.
• Flow Settings: Most POCs use pulse flow; those who need continuous flow should consult a respiratory therapist.

Ask your doctor for a prescription and flow rate recommendation before purchasing.

❓ Frequently Asked Questions

Do I need a prescription?
Yes. All oxygen concentrators require a doctor’s prescription.

Can I travel with a portable oxygen concentrator?
Yes, if it’s FAA-approved (all the models above are).

What’s the difference between pulse and continuous flow?
Pulse flow delivers oxygen when you inhale. Continuous flow delivers a constant stream. Most POCs use pulse flow due to battery and size constraints.
