Best Portable Oxygen Concentrators

Compare Features, Benefits and Prices of Portable Oxygen Concentrators

Portable oxygen concentrators (POCs) are an essential part of supplemental oxygen therapy for active adults with COPD who want to maintain an independent lifestyle. But, if you're new to oxygen therapy, how do you go about choosing a POC that will best meet your needs? Begin by asking yourself how the model you're considering compares to other models based on:

  • Affordability
  • Ease of use
  • Convenience 
  • Portability
  • Noise level
  • Size and weight
  • Pulse-dose vs. continuous flow

Then, compare prices to get the quality you need at a price you can afford. Remember, too, Medicare (and some private insurances) will pay for a POC if you meet certain criteria. Find out if you qualify for Medicare reimbursement or for reimbursement through private insurance.

Which POC is Best?

By far, the most common question I get asked about portable oxygen concentrators is which one is best. That's a difficult question to answer because everyone's different. When asked, the answer that I give most frequently is that the model you choose should complement your ​lifestyle and individual oxygen needs.

To give you an idea of what they have to offer, the list below includes features and benefits of POCs that are among the most popular:
