Best Portable Oxygen Concentrators in 2023

Portable Oxygen Concentrators 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 increase oxygen levels 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 suffering from low oxygen concentration might be mentally confused, lose consciousness, be unable to coordinate or become giddy. In extreme cases, the individual will experience nausea, faint, and, worse, may die.

Hypoxemia is the term used to describe the blood’s lower-than-normal oxygen levels. People developing the condition will exhibit signs like anxiety and confusion, and sometimes they become excessively restless. And that is the reason why the best portable oxygen concentrator should be used to help reverse the effects.

What are Portable Oxygen Concentrators?

“Portable” means a thing that can be carried around easily. Therefore, a portable oxygen concentrator is smaller, 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 do Portable Oxygen Concentrators Works?


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

Flow Rate

Your doctor primarily determines the capabilities of your 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 flow rate level that you need, whether high or low.

Remember that companies manufacture oxygen concentrators, which all come with different flow rate levels regarding the user’s needs. 

Oxygen concentration levels

The filtration system and the nitrogen sieve system in a concentrator will determine the level of pure oxygen content delivered to a patient. Therefore, different concentrators offer different concentration levels, and a high-powered red oxygen concentrator would be helpful for patients who need high oxygen flow rates. A smaze oxygen concentrator usually features low flow rate levels.


Portable oxygen concentrators are available from different vendors but should not be expected to provide high flow rates, as they are portable. 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 sufficient with 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.

Another vital factor 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 correctly and if they don’t detect a breath.
