Portable Oxygen Concentrators or POCs are special breathing devices used by people dealing with sleep apnea or other breathing-related conditions. A POC is extremely helpful at times when your body isn’t inhaling the optimum amount of oxygen on its own. In that case, you will have to use an oxygen concentrator to recoup for the lack of oxygen inhaled by your body.

However, things are changed now, as oxygen concentrators have become smaller and more efficient, thus making it easier for people to use them.

What To Know About Portable Oxygen Concentrators?

There are two types of Portable Oxygen Concentrators, which are; Intermittent Flow or Continuous Flow. Intermittent flow concentrators are also known as pulse flow because these units can be set to adjust the rise time, so the level of oxygen can be increased or decreased in accordance to the breathing cycle of the user. Oxygen will be provided only when the user inhales, not when he/she exhales, thus saving oxygen in the process.

Then comes the continuous flow concentrators, which will deliver oxygen continuously as per the level set by the user in the beginning. Out of the two, the intermittent oxygen concentrator is far better in terms of operation, plus it is cost effective as well.

How To Choose The Best Portable Oxygen Concentrator

A portable oxygen concentrator can help you with sleep apnea and breathing problems, but in order to do so, it needs to operate efficiently day-in and day-out. To find such a machine, you will have to pay attention to the following factors.


Portable oxygen concentrators can be used at home as well as outdoors. Highly portable oxygen concentrators are very lightweight and come in a wide range of sizes. The POCs operate on batteries, which is also a variable aspect, as some POCs may have larger battery life than others. So, you need to make sure that you are getting the product that you need in the first place.


With every POC having the exact same operation, the factor that will help you decide as to which POC you should take to your home is the price of the unit. You will see portable oxygen concentrator being sold for thousands of dollars and then there are models, which you can get at less than $500, so if you are getting the exact same thing in a $500 POC, then why waste $1000+? Be smart and choose the product that is well within your budget and offers all the necessary features as well.


This is a very important factor because most people use POCs at night when they are about to go to sleep. After wearing the CPAP mask and turning on the Portable Oxygen Concentrator when they lay down on their adjustable beds, the last thing they want to hear is the whirring sound coming out of the portable oxygen concentrator.

That whirring sound will not please them at all. I hope you too want a POC that doesn’t make any sound while operating, right? So, find a machine that produces 45dB or lesser noise.


In a portable oxygen concentrator, one thing that we all would like to see is its portability, which can only come if the machine is sleek, lightweight and easy to carry. Look for a machine that doesn’t weight more than 15 lbs or else it will become difficult for you to move with it.

Level Of Oxygen Purity

This factor also varies from model to model, but as long as you are getting at least 90 percent oxygen purity, then that’s great.

Battery Life

You need to check as for how many hours the machine operates on a single full charge. The POC with the longest operation on a single charge is the one you should keep at the top of your list. Also, check as to how many hours does the battery takes to recharge because some batteries take 3-4 hours, which is way too more.

Ease Of Use

Check how easy or difficult it is to use the POC. The machine should be comfortable in using even for a person who is not too well-versed with technology. If it is easy to change the level of oxygen, turn on/off power saving mode and sleep mode, then the portable oxygen concentrator is easy to use.


Portable oxygen concentrators are special machines designed for people who need supplementary treatment for their breathing conditions. It is possible for people to correct their sleep-related problems, which occur because of shortness of breath. I have discussed seven portable oxygen concentrators, which are packed with many incredible features to make your life easier at home as well as outdoors.
