What to Consider Before You Buy a Portable Oxygen Concentrator

Price

As mentioned earlier, the initial investment for an oxygen concentrator can be steep. This makes affordability a significant concern for oxygen users seeking a suitable POC.

When searching for an affordable portable oxygen concentrator, it’s important to compare the upfront cost against the long-term benefits.

Remember that while the initial price is high, a POC is an investment that will pay for itself. Oxygen tanks are cheaper but tank refills are an ongoing expense.

If you’re looking for the best portable oxygen machine on a budget, the SimplyGo Mini and the X-PLOR are good options. Both are priced under $2000, have FAA approval, and can be charged using both AC and DC power sources.

For a comparison of how they measure up in terms of user experience, maintenance requirements, and more, see our detailed review of the SimplyGo Mini vs. X-PLOR.

Battery Life

For many aspiring POC owners, battery life is the most important feature. No one wants to worry about low battery power on their outings.

Since battery runtime depends on the specific oxygen setting, we recommend closely examining the battery duration information for each POC.

This information can be found in the “Technical Specifications” section of each machine’s user manual. 

In general, if you want more battery power, the best portable oxygen machine is one that offers a 16-cell/extended battery. The SimplyGo Mini Extended Battery for instance, gives you double the runtime when compared to the standard option.  

Another solution to increase battery runtime is buying multiple batteries. This method lets you charge one battery while using the other, ensuring you have an uninterrupted oxygen supply.

Weight

Finding the right balance between weight and oxygen output is key when buying a portable oxygen concentrator. You’ll want a POC that meets your prescribed oxygen treatment demands and is lightweight enough for you to comfortably carry for hours.

In our portable oxygen concentrator review, the Belluscura X-PLOR stands out as the most lightweight pulse dose POC. However, it does sacrifice battery duration (up to 4 hours only at lowest setting) for greater portability. 

Oxygen Output

Oxygen output determines the amount of oxygen available to the user per minute. It is measured in “milliliters per minute” (mL/min) or more commonly, in “liters per minute” (L/min or LPM).

We strongly recommend making sure your POC is capable of delivering your prescribed amount of oxygen. Always check your prescription before buying. When in doubt, ask your doctor if the oxygen machine you have your eyes on is right for you. 

If getting in touch with your doctor is too much of a hassle, why not consult our medical staff?

Our respiratory therapists and sleep technicians can let you know what machines are compatible with your prescription and provide expert recommendations. Best of all, no appointment is needed!

The Verdict: Which Pulse Dose Portable Oxygen Concentrator Should You Buy?

No matter your priorities or passions, there’s a portable oxygen machine available that fits your lifestyle. For the frequent traveler, the Belluscura X-PLOR, with its compact size and lightweight design, is the best portable oxygen concentrator.

If near-silent operation is your top priority, you can’t go wrong with the dependable Inogen One G5. 

Alternatively, if you don’t consider yourself tech-savvy and want an intuitive POC without all the bells and whistles, the Philips Respironics SimplyGo Mini is your best pick.

Worried about running out of battery power? The CAIRE FreeStyle Comfort boasts battery life that won’t let you down.
