This is the Best Portable Oxygen Concentrators in 2020

An Oxygen concentrator is a machine used to supply up to 95% of pure oxygen to patients if you have never had someone close to you use the oxygen concentrator it might be puzzling when you meet someone using it.  So why do people use oxygen concentrators even at home? An oxygen concentrator helps to increase the levels of oxygen in the blood, which means that individuals who use oxygen concentrators lack enough oxygen.

Oxygen deficiency is detrimental to the heart and overall body health. A person who suffers from low oxygen concentration might be mentally confused, can lose consciousness, be unable to coordinate, or just become giddy. In extreme cases, the individual will experience nausea, might faint, and, worse still, they may die.

Hypoxemia is the term used to describe the lower than normal levels of oxygen in the blood, and people who are developing the condition will exhibit signs like anxiety, confusion and at times they become excessively restless. And that is the reason why the best portable oxygen concentrator should be used to help reverse the effects.

What is Portable Oxygen Concentrators?

Therefore, a portable oxygen concentrator is one that comes in a smaller size, is mobile and provides oxygen therapy to individuals who require additional oxygen than the levels present in ambient air. We will, therefore, try to cover everything about portable oxygen concentrators.

How does Portable Oxygen Concentrators Works?


The Portable oxygen concentrator works by drawing in ambient air that consists of nitrogen and oxygen from within the room that it has been placed, which then goes through the compressor where oxygen is compressed. Nitrogen is then removed from the air, and the mechanism therein adjusts the way the air is delivered. The released air is completely purified and is provided to the patients by the use of a nasal cannula, mask, or oxygen tubing.

Things to consider before buying Portable Oxygen Concentrators

before buying Portable Oxygen ConcentratorsBefore purchasing an oxygen concentrator, there are several factors that one has to consider, such as portability. Some concentrators come with a bag to make it convenient for you to move with it anywhere, even when boarding a plane. So to help you in the selection process, we will provide you with almost everything about portable oxygen concentrators that will guide you in selecting the best portable oxygen concentrator.


Using an oxygen concentrator is not the best thing, but important, it will, therefore, have people give you unwarranted special attention. So to prevent being the center of attraction, it could be of convenience if the oxygen concentrator was whisper silent. With this regard, it all boils down to their construction and power levels.

The smaller units tend to be less noisy, whereas the high powered tends to be a bit noisy. The high flow rate of oxygen concentrators is also noisy because they require higher power to process the high rate of oxygen flowing through them effectively.

Flow Rate

Your doctor primarily determines the capabilities of your oxygen concentrator flow rate. Flow rate refers to the rate at which oxygen moves to the patient through the machine, so before you purchase the concentrator, discuss with your doctor the level of flow rate that you need, whether high or low.

Remember that different companies manufacture oxygen concentrators, and they all come with different flow rate levels as regards the needs of the user. 

Oxygen concentration levels

The design of the filtration system and the nitrogen sieve system in an oxygen concentrator will determine the level of pure oxygen content that is delivered to a patient. Therefore, different concentrators offer different levels of concentration, a high powered oxygen concentrator would be useful for patients who need high oxygen flow rates, and a small size oxygen concentrator usually features low flow rate levels.


Oxygen concentrators come in different sizes, which will either promote or discourage portability. It, therefore, goes without saying that the units which provide higher flow rates usually are more substantial and heavier; they thus need higher power, because of the hard work that they are pre-disposed to carry out.

Portable oxygen concentrators are available from different vendors but should not be expected to provide high flow rates, as they are to be portable while in use. Remember that the filtration tools incorporated in the concentrator have been minimized to make the concentrator lightweight. Therefore, patients who require high oxygen flow rates might not be sufficed with the portable oxygen concentrators. 

Carrying containers

Some of the high powered concentrators do come with a carrying container. However, the bags and containers work effectively with the portable concentrators ensuring that you get your constant dose of oxygen wherever you want to go.

Another vital factor that you should consider when buying portable oxygen concentrators is the ease of changing the filter system. Some concentrators will warn you if the machine is not working right, also if they don’t detect a breath.

Summary / Conclusion

The above excerpt aims to give you information about everything about portable oxygen concentrators to guide you in decision making. Different patients have different needs and thus different types of concentrators; however, before you settle for a concentrator, let your doctor recommend one about your condition. All the above portable oxygen concentrators are functional and have incorporated innovative features.
