Portable Oxygen Concentrators

Portable oxygen concentrators are lightweight, travel-friendly oxygen generators that are designed for oxygen therapy on-the-go. Unlike home oxygen concentrators, which require an AC power source, portable oxygen machines offer greater versatility in power options. They can run on machine-specific lithium batteries as well as AC and DC power.

We break down the differences between portable oxygen concentrators and home use concentrators in this chart.

The Benefits of Using a Portable Oxygen Machine

More Cost-Effective Over Time

Portable oxygen machines have a higher upfront cost than oxygen cylinders, but unlike tanks, they don’t run out of oxygen. This eliminates recurring costs due to oxygen tank refills.

Travel-Friendly

Many portable O2 machines are FAA-approved for use on commercial airlines. Oxygen cylinders, on the other hand, are not allowed on planes.

Greater Independence

Portable oxygen concentrators give users the freedom to leave the house and live their lives, greatly improving their quality of life.

Discreet

Modern portable oxygen machines are compact and stylish units that deliver medical-grade oxygen without sacrificing aesthetics. Many of them can be transported in small carry-on bags or totes that don’t draw attention in public.

Safer Than Oxygen Tanks

Oxygen tanks contain compressed oxygen gas under high pressure and can be dangerous if stored incorrectly or dropped. Portable O2 concentrators, on the other hand, won’t pose a danger if accidentally dropped or tipped over.

How to Choose a Portable Oxygen Concentrator: Recommendations from RespShop Experts

With so many portable oxygen concentrators for sale online, how do you determine which one is the best for you? Here are key features we recommend paying attention to when shopping for a portable O2 generator.

Size and Weight

The unit should be light and compact enough for you to comfortably carry around for long periods.

Battery Life

The longer the battery life, the longer you can go without having to recharge your battery or replace it. However, keep in mind that there is a trade-off between battery life and price: extended-life batteries typically cost double that of standard ones.

Price

Portable oxygen machines range in price from a little less than $2000 to over $3000. The cost largely depends on the brand, battery life, oxygen capabilities, length of warranty, and the presence of any smart features.

Oxygen Delivery Mode

Pulse Dose: machine detects breathing and provides a bolus, or “pulse” of oxygen.

Continuous Flow: machine supplies a constant stream of oxygen.

Dual Mode: some portable O2 machines feature both oxygen delivery modes.

Digital and Smart Features

Newer portable oxygen machines feature smartphone connectivity for real-time monitoring. It’s a convenient way to keep track of a loved one’s oxygen usage so you know they are receiving the therapy they need.

Maintenance Requirements

Some machines feature external air filters that need regular cleaning. Others don’t need any cleaning other than the occasional wipe down with a damp cloth.

Warranty

Most portable O2 concentrators come with 2-year manufacturer warranty, although some brands offer a 3-year warranty.

Why is Regular Maintenance of Portable O2 Generators Important?

Regular maintenance of portable oxygen generators is crucial for both the machine's longevity and your health. Fortunately, these machines are easy to maintain, typically requiring only weekly filter cleanings.

Filters keep dust and debris from entering the machine. Regular cleaning not only extends the lifespan of the concentrator but also protects you from inhaling dust and other airborne particles.

Depending on how often you use your concentrator, you may need to replace the oxygen sieve bed annually. Oxygen sieve beds, also known as oxygen cartridges, are the heart of the machine. They produce pure oxygen by removing nitrogen from the air, concentrating the oxygen.
