Oxlife Freedom Portable Concentrator Review

For a long time receiving an oxygen prescription meant giving up your freedom and independence to do the things you want to do, how you want to do it. Similar to what the Covid pandemic did to the world. For respiratory patients, oxygen tanks were the only guaranteed source of medical-grade oxygen. They were so cumbersome, heavy, and difficult to refill and maintain. But, to address these nightmares oxygen patients were experiencing, manufacturers of oxygen delivery systems made huge strides. The introduction of portable oxygen concentrators in the early 2000s was perhaps one of the first notable steps.

A portable oxygen concentrator unlike the oxygen tanks which store oxygen is an electrical device that draws oxygen from the air around them while filtering out other unnecessary gases. One of those portable oxygen concentrators is the Oxlife Freedom portable oxygen concentrator. Like other O2 Concepts devices, it is known for its patented energy smart technology – the Dynamic Network Analysis: DNA technology and its Dryer Management System. In addition, it offers pulse flow settings to oxygen patients, as opposed to the Oxlife Independence which also delivers continuous flow oxygen. Let’s take a closer look at the features below.


What are the Features of the Oxlife Freedom Portable Oxygen Concentrator?

Special features:

Dryer management system: This helps remove moisture from the air coming into the concentrator, to preserve the sieve beds and the unit in extension. It is one of the features peculiar to devices made by O2 Concepts.

DNA technology: This is a safety feature where the unit connects via a network server system to healthcare providers and manufacturers. This way, the concentrator is monitored for normal functioning.

Intelligent delivery system: You don’t need to worry about using this oxygen concentrator while you are sleeping. The Oxlife Freedom intelligent delivery system will carefully monitor your breathing. Even shallow mouth breathing may be detected by this technology, so you won’t have to worry about receiving enough oxygen whilst asleep.


Other features:


Size, Weight, and Design

The Oxlife Freedom is a relatively small unit, measuring 9.4 inches in height, 3.4 inches in depth, and 9 inches in width. It weighs 5.88 pounds, which ranks it as one of the lightest portable oxygen concentrators on the market.

Being this small and lightweight, the unit would not cause any obstruction in the room and would be easy to move around with.


Flow Rate

Like a few other portable oxygen concentrators, the Oxlife Freedom portable oxygen concentrator provides only pulse flow oxygen settings. It uses its intelligent delivery system to read your breathing rate and deliver the pulse flow rate suited for that activity. The unit has pulse flow settings from 1 to 5 and a maximum oxygen output of 3,000mls/minute.


Battery Life

The word “Freedom” in the name of this oxygen concentrator is there because it does give you freedom. It has an impressively long battery life that can last hours. So, you don’t need to worry about running out of power whilst you’re out on errands. It makes use of a lithium-ion battery which has a very good battery duration.

On another note, there is the option for the single battery for short trips and the double battery for longer errands. The single battery lasts for about 4 hours on a pulse setting of 2, while the double battery would last you double the time of the single – 8 hours also on setting 2.

So how are these batteries charged when they are used up? There are three charging options which include:

  • AC power supply: The concentrator can be connected to the standard wall outlet and allowed to work and charge at the same time. This takes about 2 hours.
  • DC power supply: For those that spend more time on the move in their vehicles, it could be charged with the cigarette lighter slot via a DC power adapter. This shouldn’t take long, but if it is being used at the time, charging would definitely take longer.
  • External battery charger: This comes in really handy for holiday trips. You wouldn’t need to stop your oxygen therapy.


Control panel

Its control panel is known to be user-friendly, with a trans-reflective screen in both low and bright light. The prominent indicators on the screen are those for the flow rate and battery power. Its buttons are large and easily accessible, making quick changes to the flow rate quite simple. Whenever there is a problem that needs your attention, an audible alarm would go off and the issue would be clearly displayed on the screen. So, you are never confused. You can also tell if you are currently receiving remote access service or being GPS tracked by indicators at the top of the screen.


Oxygen concentration

This oxygen concentrator maintains oxygen purity between 87% and 95% like a standard portable unit.


Accessories that can be used with the Oxlife Freedom Portable Oxygen Concentrator

  1. Accessory bag or Carry bag
  2. Rechargeable battery (Two batteries – single or double)
  3. AC power supply
  4. DC power supply
  5. External battery charger
  6. Filter
  7. Oxygen tubing

Is the Oxlife Freedom FAA Approved?

Yes, it does. It is approved for in-flight use.



The Oxlife Freedom oxygen concentrator has a manufacturer’s 3-year warranty for the device itself, and a 1-year warranty for the sieve beds that come with it. However, this information should always be confirmed by the dealer before purchase.



So, I guess O2 Concepts were not exaggerating when they named the system “Freedom”. With Freedom, you’ll be able to leave the house and accomplish more than you could have imagined while on oxygen therapy. The device is far lighter, smaller, and more adaptable than the oxygen tanks that came before it.

It also features “smart” technology that keeps an eye on your oxygen consumption, device health, and much more to help you take charge of your health. Additionally, it keeps you in touch with the manufacturers and respiratory specialists who can assist you in an emergency. Take the bold step and give this oxygen unit a try.ox
