The Best Portable Oxygen Concentrators of 2020

Respiratory problems and breathing disorders are among the most significant health concerns that anyone ever experiences, but they no longer have to rid you of your independence. A range of specialized respiratory aids are now readily available, restoring comfort and normality to the lives of millions. Portable oxygen concentrators are among the most beneficial products on the market, delivering transformations that were once unfathomable. Better still, it can often fit directly in your pocket.

What Exactly Is A Portable Oxygen Concentrator?

Portable oxygen concentrators, otherwise known as POCs, are medical devices that deliver increased oxygen levels to help promote increased blood oxygen levels in patients. While oxygen concentrators have existed for many years, the lightweight oxygen concentrators offer mobility. In turn, users can now gain the benefits of an oxygen concentrator while they are on the go. POCs work on the following basic principle:

  • The device receives natural air, which is composed primarily of nitrogen and partly oxygen.
  • It then purifies the air, removing some of the nitrogen until oxygen is the main substance.
  • The POC subsequently spits the air out directly into the user's respiratory system.

POCs are, like traditional oxygen concentrators, deliver the purified air through a mask and tubes. Lightweight portable oxygen concentrators can be powered by an electrical outlet or batteries while the best portable oxygen concentrators are also equipped with adapters to facilitate charging while driving. The vast majority of models are pocket-size, although some bigger units that can still be carried around (in the same way that an oxygen tank might) can be classified under this section too.

Who Are Portable Oxygen Contractors For?

Oxygen contractors, including POC devices, are normally exclusively open to individuals that have been medically advised to purchase one. This advice is usually the result of a medical diagnosis relating to respiratory health issues that can benefit from oxygen therapy. Aside from confirming that oxygen therapy is the most suitable solution, a doctor can inform patients and caregivers about what density of filtration is required. This is traditionally measured in liters per minute (LPM). 

POCs can be used to treat a wide range of acute and chronic conditions to deliver short-term blood oxygen improvements or ongoing regulation. The most common issues include the following:

  • Asthma – when an asthma attack strikes, a burst of increased oxygen will make it easier to breathe and help combat the issues caused by mucus accumulation and airway inflammations.

  • Chronic obstructive pulmonary disease – COPD is a chronic lung condition where individuals will need regular, and potentially constant, oxygen support. FAA-approved portable oxygen concentrators are the best solution for ongoing care.

  • Respiratory Distress Syndrome – RDS sufferers need oxygen therapy because their lungs often collapse as a result of reduced surfactant production. However, this is a condition usually limited to infants, particularly those that have been prematurely.

  • Bronchopulmonary dysplasia – BPD sufferers will usually require surgery to treat their long-term lung condition, but may also use ongoing oxygen therapy following surgery.

  • Pneumonia – when you have pneumonia, the infection and inflammation can fill your lungs with fluid. Oxygen therapy courtesy of POCs can help regulate oxygen levels to support the body's natural defense systems.

  • Sleep apnea – if you regularly experience sleep apnea, the use of oxygen can stop the throat from collapsing while also promoting better oxygen levels.

  • Cystic fibrosis – the potentially life-threatening condition causes a thick, sticky mucus to block tubes and airways but the best portable oxygen concentrators can help manage the condition through ongoing usage.

A number of less common uses are possible too. Anyone experiencing respiratory disorders should seek medical support to determine whether oxygen therapy is a suitable management tool.

What Benefits Can POCs Deliver?

Depending on the individual circumstances of the breathing condition, high flow portable oxygen concentrators can deliver a wide range of benefits for users, including but not limited to;

  • A better night's sleep due to increased oxygen saturation levels, particularly for individuals who suffer from sleep apnea or asthma. 
  • Increased energy levels due to improved sleep and the fact that your lungs are no longer struggling to breathe fresh air.
  • An improved sense of independence as you can breathe more easily, even on the go, thanks to the POC device's capabilities.
  • A greater sense of mental clarity as the increased blood oxygen feeds the brain with the sweet, sweet O2 it craves.
  • Reduced physical discomfort due to better lung performance and oxygen supplies to all organs throughout the body.

In turn, oxygen therapy provided by the best portable oxygen contractors will significantly increase your quality of life. Whether it's managing discomfort, gaining direct health benefits, or restoring normality to your daily activities doesn't matter. Your opportunities for social activities will improve while you'll also have better control of completing tasks around the home. 

It is no exaggeration to state that individuals living with respiratory problems will enjoy a far brighter future as a result of oxygen therapy. In many cases, it can actively extend your lifespan too. For the best results, though, it's imperative that you find a suitable POC unit.

Portable Oxygen Contractors Versus Oxygen Tanks

The fundamental functions of POCs and traditional oxygen tanks are almost identical. They help treat and manage symptoms related to the same extensive list of breathing conditions. However, the differences between the two types of units do mean that each option is better suited to some situations more than others. While there is no one right or wrong solution for everyone, it's important to analyze the pros and cons of each.

Portable Oxygen Contractors Pros & Cons


  • The biggest benefits gained from portable oxygen contractors is that they extract and filter the surrounding air. This means that there is no limit to how much oxygen is available.
  • POCs additionally offer greater lifestyle upgrades due to their size and lightweight nature. When supported by the choice of battery or A/C power, you can make it work in a versatile way.
  • The units are a cheaper long-term investment as you will not need to replace gas canisters or add new and costly features. You are essentially set to go from day one.


  • The biggest challenge relates to power supplies. When the unit isn't plugged in, it's likely that you'll gain around five hours of battery power. If you're out for longer, spare batteries are needed.
  • POCs are quite loud, especially if you choose an inferior machine. While users will probably acclimatize to this quite quickly, it's likely that it may cause disruption for loved ones.
  • The initial outlay is costly and will require a $1,500+ investment even for a basic model. The best portable oxygen contractors are closer to the $2,500-$3,000 mark.

Standard Oxygen Tanks Pros & Cons


  • The most obvious benefit is that oxygen tanks do not require a power supply, either through A/Cs or batteries. This does, of course, mean you'll have access to its full function at any time.
  • Oxygen tanks are additionally silent in their performance, aside from the sound of actually breathing in and out. This is a noticeable benefit over POCs, especially for loved ones.
  • Oxygen tanks are far cheaper as an initial purchase as you do not need to invest in the POC unit, which makes the outlay far smaller.


  • Oxygen tanks are very heavy, particularly when full, and are not portable unless you have a specialized cart. This means that any lifestyle benefits are severely impacted as a direct consequence.
  • The costs are greater in the long haul because oxygen canisters must be replaced on a frequent basis. Even when oxygen supplementation isn't needed on a 24/7 basis, it becomes very costly.
  • Oxygen tanks only deliver a certain amount of oxygen. If it runs out, you will no longer have access to blood oxygen upgrades. When going away, you'll have to take several items.

What Is Pulse Oxygen Flow And Continuous Oxygen Flow

When checking out lightweight portable oxygen concentrators, you will often see the terms pulse flow and continuous flow. They describe the two ways in which the filtered oxygen can be delivered to your nasal passage. 

Pulse oxygen, also known as pulse dose or PD, is when the oxygen is delivered based on your breathing habits. So, it adapts to your rate of breathing and offers a fully personalized performance. It gives you more oxygen when your body needs it, and less when the body is back to a 'normal' breathing routine.

Conversely, continuous flow is when the oxygen is distributed at a set rate. The liter per minute rate can be set accordingly, but it will stay at a constant. Each solution is suited to some situations better than others while the best portable oxygen contractors are capable of performing both functions. After all, your oxygen needs can change drastically throughout the day.

What To Look For In A Portable Oxygen Contractor

Confirming that a portable oxygen contractor will improve your quality of life is one thing, but finding the right unit is another challenge altogether. When analyzing the marketplace, your natural instinct is to look solely at portable oxygen concentrators prices. While this is a key factor, you should be prepared to check out a wide range of contributing factors. The most telling features are listed below:


First and foremost, the best portable oxygen contractor must be safe to use for your specific breathing disorder and lifestyle. A medical diagnosis will give you a list of attributes related to your condition. Crucially, if you are planning to use it for travel to a vacation, you must seek Federal Aviation Association, or FAA approved portable oxygen concentrators.

Size and weight

The physical dimensions of the portable oxygen contractor are essential features of the decision-making process. After all, if it's not truly portable, you may as well stick with a traditional oxygen contractor unit. A POC can weigh as little as 3lbs whereas standard units are around 50lbs. Do not underestimate the significance that this can have on your lifestyle and daily habits.

Liter flow

High flow portable oxygen concentrators are essential for those with severe chronic respiratory conditions. However, individuals with progressive troubles may also want to look at devices with higher liter flow levels as a precaution for the future. The settings can be lowered in the meantime before being increased if and when the circumstances require it.


While it's not the only key factor, you should not ignore the costs. After all, the best portable oxygen concentrators will cost a four-figure fee. Cheap doesn't necessarily equate to value, particularly when you consider the impact that the purchase will have on your health. An affordable unit that delivers life-changing benefits for many years is the ideal solution.


No two people are the same, and you need a POC that can deliver the exact level of supplementary oxygen that you require. Some devices can use both pulse-flow and continuous flow oxygen. Whether it's a hybrid or a unit that focuses on just one of those features, the ability to adjust the settings over time is crucial. Only a personalized item will bring comfort and performance.


Oxygen machines and equipment naturally make mechanical sounds from the power supplies and air filtration mechanisms. A unit that runs at a low decibel level will add to the convenience of your daily life while it can also protect your hearing health. You will not achieve total silence, but finding a quiet portable oxygen concentrator can make a world of difference.


Choosing a well-known manufacturer, like Vital Lite or Inogen One, brings an increased level of reliability. Furthermore, your increased trust in the brand will deliver peace of mind. On a side note, it can also aid the cause when looking for accessories, repairs, or replacement parts. For the sake of performance and convenience, do not overlook this issue.

Battery power


When you compare portable oxygen concentrators, you must remember that they are designed to add independence. However, the lifestyle benefits are a little redundant if the unit dies after just an hour. Even with spare batteries, it would restrict you in many aspects of daily life.

Portable Oxygen Contractors FAQs

Are POCs covered by Medicare?

Unfortunately, no. Medicare slashed its reimbursement rates for oxygen equipment in half in 2013, leaving providers unable to maintain their contracts. As such, Medicare no longer buys or covers the costs associated with portable oxygen contractors.

Why should I only buy from trusted suppliers?

When checking portable oxygen concentrators prices, it may be possible to find cheaper alternatives. However, if your doctor has prescribed oxygen therapy, it is not an issue where you can afford to cut corners. Your health is far too important to take risks. 

What accessories should I consider?

While not all users will need all accessories, there is a long list to consider. The best are; a carry case or backpack, spare batteries, charger adapters, backup oxygen tubes, battery charging units, and spare charger cables. 

How quickly will I notice the benefits?

When using the oxygen contractor unit, the benefits of restored blood oxygen levels can be felt instantly. It will put your body and mind at ease. Moreover, the lifestyle rewards are delivered right away, although it can take a little adjustment. 

What happens if I take too much oxygen?

Anyone that has a respiratory needs the supplementary oxygen. However, too much oxygen in the blood can cause toxicity, leading to serious illnesses. This is one of the many reasons for seeking medical prescriptions rather than self-diagnosis.

What else should I know about using POCs?

When using a POC unit, it's vital that you avoid flammable products and remain 2m away from heat sources. Avoiding smoking, including secondhand smoke, is also vital while oxygen containers must stay upright at all times.


Portable oxygen contractors are incredibly important medical devices that filtrate the air to promote improved blood oxygen levels for individuals living with respiratory conditions and breathing disorders. While primarily thought of as a unit to be used by senior citizens, they also offer effective symptom management for much younger people that have chronic conditions. 

Whether oxygen therapy is required for acute or chronic symptoms, matching yourself to the best portable oxygen contractor unit will deliver immediate benefits that will transform your life for the better.
