What Is the Difference Between Oxygen Concentrators of Different Brands?

A portable oxygen concentrator is a medical oxygen system used to treat respiratory disorders. There are many reasons why people need oxygen therapy as they age. Health issues such as sleep problems, COPD, low blood iron, or surgical recovery will leave us with low oxygen. 


With so much information on the Internet, it is easy to get overwhelmed. It can be tough to distinguish between different brands without the correct information and choosing the right one for you. 

Here is a short guide to help you choose. 

Choosing A Portable Oxygen Concentrator 

Unlike other oxygen devices like bulky oxygen concentrators, portable oxygen concentrators are built to be compact and powerful.  They provide the individual with as much mobility as possible while also guaranteeing their oxygen requirements. 

Oxygen concentrators are pretty complicated. There are several variables to consider when choosing a POC, including:

  • the supply of oxygen
  • battery capacity
  • weight
  • scale
  • model
  • accurate oxygen sensing
  • simple controls
  • price
  • size/portability
  • operating range of altitude
  • noise
  • power efficiency
  • need for upkeep

It's necessary to understand your oxygen requirements before buying any portable oxygen concentrator. Ask these questions the next time you go to the doctor or pulmonologist:

  • How frequently do I need per day to use oxygen?
  • When sleeping, can I use my oxygen concentrator?
  • Should I use oxygen for pulse flow or continuous stream?
  • What are my oxygen requirements?      

You can easily provide your respiratory consultant with the number when you buy a portable oxygen concentrator. This helps them authenticate your use of oxygen.
